CHAPTER TWENTY-NINTH.

Signs of Vegetation.—The Fantastic Notion of a French Author.—A Magnificent Country.—The Kingdom of Adamova.—The Explorations of Speke and Burton connected with those of Dr. Barth.—The Atlantika Mountains.—The River Benoué.—The City of Yola.—The Bagélé.—Mount Mendif.

From the moment of their departure, the travellers moved with great velocity. They longed to leave behind them the desert, which had so nearly been fatal to them.

About a quarter-past nine in the morning, they caught a glimpse of some signs of vegetation: herbage floating on that sea of sand, and announcing, as the weeds upon the ocean did to Christopher Columbus, the nearness of the shore—green shoots peeping up timidly between pebbles that were, in their turn, to be the rocks of that vast expanse.

Hills, but of trifling height, were seen in wavy lines upon the horizon. Their profile, muffled by the heavy mist, was defined but vaguely. The monotony, however, was beginning to disappear.

The doctor hailed with joy the new country thus disclosed, and, like a seaman on lookout at the mast-head, he was ready to shout aloud:

“Land, ho! land!”

An hour later the continent spread broadly before their gaze, still wild in aspect, but less flat, less denuded, and with a few trees standing out against the gray sky.

“We are in a civilized country at last!” said the hunter.

“Civilized? Well, that’s one way of speaking; but there are no people to be seen yet.”

“It will not be long before we see them,” said Ferguson, “at our present rate of travel.”

“Are we still in the negro country, doctor?”

“Yes, and on our way to the country of the Arabs.”

“What! real Arabs, sir, with their camels?”

“No, not many camels; they are scarce, if not altogether unknown, in these regions. We must go a few degrees farther north to see them.”

“What a pity!”

“And why, Joe?”

“Because, if the wind fell contrary, they might be of use to us.”

“How so?”

“Well, sir, it’s just a notion that’s got into my head: we might hitch them to the car, and make them tow us along. What do you say to that, doctor?”

“Poor Joe! Another person had that idea in advance of you. It was used by a very gifted French author—M. Méry—in a romance, it is true. He has his travellers drawn along in a balloon by a team of camels; then a lion comes up, devours the camels, swallows the tow-rope, and hauls the balloon in their stead; and so on through the story. You see that the whole thing is the top-flower of fancy, but has nothing in common with our style of locomotion.”

Joe, a little cut down at learning that his idea had been used already, cudgelled his wits to imagine what animal could have devoured the lion; but he could not guess it, and so quietly went on scanning the appearance of the country.

A lake of medium extent stretched away before him, surrounded by an amphitheatre of hills, which yet could not be dignified with the name of mountains. There were winding valleys, numerous and fertile, with their tangled thickets of the most various trees. The African oil-tree rose above the mass, with leaves fifteen feet in length upon its stalk, the latter studded with sharp thorns; the bombax, or silk-cotton-tree, filled the wind, as it swept by, with the fine down of its seeds; the pungent odors of the pendanus, the “kenda” of the Arabs, perfumed the air up to the height where the _Victoria_ was sailing; the papaw-tree, with its palm-shaped leaves; the _sterculier_, which produces the Soudan-nut; the baobab, and the banana-tree, completed the luxuriant flora of these inter-tropical regions.

“The country is superb!” said the doctor.

“Here are some animals,” added Joe. “Men are not far away.”

“Oh, what magnificent elephants!” exclaimed Kennedy. “Is there no way to get a little shooting?”

“How could we manage to halt in a current as strong as this? No, Dick; you must taste a little of the torture of Tantalus just now. You shall make up for it afterward.”

And, in truth, there was enough to excite the fancy of a sportsman. Dick’s heart fairly leaped in his breast as he grasped the butt of his Purdy.

The _fauna_ of the region were as striking as its flora. The wild-ox revelled in dense herbage that often concealed his whole body; gray, black, and yellow elephants of the most gigantic size burst headlong, like a living hurricane, through the forests, breaking, rending, tearing down, devastating every thing in their path; upon the woody slopes of the hills trickled cascades and springs flowing northward; there, too, the hippopotami bathed their huge forms, splashing and snorting as they frolicked in the water, and lamantines, twelve feet long, with bodies like seals, stretched themselves along the banks, turning up toward the sun their rounded teats swollen with milk.

It was a whole menagerie of rare and curious beasts in a wondrous hot-house, where numberless birds with plumage of a thousand hues gleamed and fluttered in the sunshine.

By this prodigality of Nature, the doctor recognized the splendid kingdom of Adamova.

“We are now beginning to trench upon the realm of modern discovery. I have taken up the lost scent of preceding travellers. It is a happy chance, my friends, for we shall be enabled to link the toils of Captains Burton and Speke with the explorations of Dr. Barth. We have left the Englishmen behind us, and now have caught up with the Hamburger. It will not be long, either, before we arrive at the extreme point attained by that daring explorer.”

“It seems to me that there is a vast extent of country between the two explored routes,” remarked Kennedy; “at least, if I am to judge by the distance that we have made.”

“It is easy to determine: take the map and see what is the longitude of the southern point of Lake Ukéréoué, reached by Speke.”

“It is near the thirty-seventh degree.”

“And the city of Yola, which we shall sight this evening, and to which Barth penetrated, what is its position?”

“It is about in the twelfth degree of east longitude.”

“Then there are twenty-five degrees, or, counting sixty miles to each, about fifteen hundred miles in all.”

“A nice little walk,” said Joe, “for people who have to go on foot.”

“It will be accomplished, however. Livingstone and Moffat are pushing on up this line toward the interior. Nyassa, which they have discovered, is not far from Lake Tanganayika, seen by Burton. Ere the close of the century these regions will, undoubtedly, be explored. But,” added the doctor, consulting his compass, “I regret that the wind is carrying us so far to the westward. I wanted to get to the north.”

After twelve hours of progress, the Victoria found herself on the confines of Nigritia. The first inhabitants of this region, the Chouas Arabs, were feeding their wandering flocks. The immense summits of the Atlantika Mountains seen above the horizon—mountains that no European foot had yet scaled, and whose height is computed to be ten thousand feet! Their western slope determines the flow of all the waters in this region of Africa toward the ocean. They are the Mountains of the Moon to this part of the continent.

At length a real river greeted the gaze of our travellers, and, by the enormous ant-hills seen in its vicinity, the doctor recognized the Benoué, one of the great tributaries of the Niger, the one which the natives have called “The Fountain of the Waters.”

“This river,” said the doctor to his companions, “will, one day, be the natural channel of communication with the interior of Nigritia. Under the command of one of our brave captains, the steamer _Pleiad_ has already ascended as far as the town of Yola. You see that we are not in an unknown country.”

Numerous slaves were engaged in the labors of the field, cultivating sorgho, a kind of millet which forms the chief basis of their diet; and the most stupid expressions of astonishment ensued as the _Victoria_ sped past like a meteor. That evening the balloon halted about forty miles from Yola, and ahead of it, but in the distance, rose the two sharp cones of Mount Mendif.

The doctor threw out his anchors and made fast to the top of a high tree; but a very violent wind beat upon the balloon with such force as to throw it over on its side, thus rendering the position of the car sometimes extremely dangerous. Ferguson did not close his eyes all night, and he was repeatedly on the point of cutting the anchor-rope and scudding away before the gale. At length, however, the storm abated, and the oscillations of the balloon ceased to be alarming.

On the morrow the wind was more moderate, but it carried our travellers away from the city of Yola, which recently rebuilt by the Fouillans, excited Ferguson’s curiosity. However, he had to make up his mind to being borne farther to the northward and even a little to the east.

Kennedy proposed to halt in this fine hunting-country, and Joe declared that the need of fresh meat was beginning to be felt; but the savage customs of the country, the attitude of the population, and some shots fired at the _Victoria_, admonished the doctor to continue his journey. They were then crossing a region that was the scene of massacres and burnings, and where warlike conflicts between the barbarian sultans, contending for their power amid the most atrocious carnage, never cease.

Numerous and populous villages of long low huts stretched away between broad pasture-fields whose dense herbage was besprinkled with violet-colored blossoms. The huts, looking like huge beehives, were sheltered behind bristling palisades. The wild hill-sides and hollows frequently reminded the beholder of the glens in the Highlands of Scotland, as Kennedy more than once remarked.

In spite of all he could do, the doctor bore directly to the northeast, toward Mount Mendif, which was lost in the midst of environing clouds. The lofty summits of these mountains separate the valley of the Niger from the basin of Lake Tchad.

Soon afterward was seen the Bagélé, with its eighteen villages clinging to its flanks like a whole brood of children to their mother’s bosom—a magnificent spectacle for the beholder whose gaze commanded and took in the entire picture at one view. Even the ravines were seen to be covered with fields of rice and of arachides.

By three o’clock the _Victoria_ was directly in front of Mount Mendif. It had been impossible to avoid it; the only thing to be done was to cross it. The doctor, by means of a temperature increased to one hundred and eighty degrees, gave the balloon a fresh ascensional force of nearly sixteen hundred pounds, and it went up to an elevation of more than eight thousand feet, the greatest height attained during the journey. The temperature of the atmosphere was so much cooler at that point that the aëronauts had to resort to their blankets and thick coverings.

Ferguson was in haste to descend; the covering of the balloon gave indications of bursting, but in the meanwhile he had time to satisfy himself of the volcanic origin of the mountain, whose extinct craters are now but deep abysses. Immense accumulations of bird-guano gave the sides of Mount Mendif the appearance of calcareous rocks, and there was enough of the deposit there to manure all the lands in the United Kingdom.

At five o’clock the _Victoria_, sheltered from the south winds, went gently gliding along the slopes of the mountain, and stopped in a wide clearing remote from any habitation. The instant it touched the soil, all needful precautions were taken to hold it there firmly; and Kennedy, fowling-piece in hand, sallied out upon the sloping plain. Ere long, he returned with half a dozen wild ducks and a kind of snipe, which Joe served up in his best style. The meal was heartily relished, and the night was passed in undisturbed and refreshing slumber.

CHAPTER THIRTIETH.

Mosfeia.—The Sheik.—Denham, Clapperton, and Oudney.—Vogel.—The Capital of Loggoum.—Toole.—Becalmed above Kernak.—The Governor and his Court.—The Attack.—The Incendiary Pigeons.

On the next day, May 11th, the _Victoria_ resumed her adventurous journey. Her passengers had the same confidence in her that a good seaman has in his ship.

In terrific hurricanes, in tropical heats, when making dangerous departures, and descents still more dangerous, it had, at all times and in all places, come out safely. It might almost have been said that Ferguson managed it with a wave of the hand; and hence, without knowing in advance, where the point of arrival would be, the doctor had no fears concerning the successful issue of his journey. However, in this country of barbarians and fanatics, prudence obliged him to take the strictest precautions. He therefore counselled his companions to have their eyes wide open for every thing and at all hours.

The wind drifted a little more to the northward, and, toward nine o’clock, they sighted the larger city of Mosfeia, built upon an eminence which was itself enclosed between two lofty mountains. Its position was impregnable, a narrow road running between a marsh and a thick wood being the only channel of approach to it.

At the moment of which we write, a sheik, accompanied by a mounted escort, and clad in a garb of brilliant colors, preceded by couriers and trumpeters, who put aside the boughs of the trees as he rode up, was making his grand entry into the place.

The doctor lowered the balloon in order to get a better look at this cavalcade of natives; but, as the balloon grew larger to their eyes, they began to show symptoms of intense affright, and at length made off in different directions as fast as their legs and those of their horses could carry them.

The sheik alone did not budge an inch. He merely grasped his long musket, cocked it, and proudly waited in silence. The doctor came on to within a hundred and fifty feet of him, and then, with his roundest and fullest voice, saluted him courteously in the Arabic tongue.

But, upon hearing these words falling, as it seemed, from the sky, the sheik dismounted and prostrated himself in the dust of the highway, where the doctor had to leave him, finding it impossible to divert him from his adoration.

“Unquestionably,” Ferguson remarked, “those people take us for supernatural beings. When Europeans came among them for the first time, they were mistaken for creatures of a higher race. When this sheik comes to speak of to-day’s meeting, he will not fail to embellish the circumstance with all the resources of an Arab imagination. You may, therefore, judge what an account their legends will give of us some day.”

“Not such a desirable thing, after all,” said the Scot, “in the point of view that affects civilization; it would be better to pass for mere men. That would give these negro races a superior idea of European power.”

“Very good, my dear Dick; but what can we do about it? You might sit all day explaining the mechanism of a balloon to the _savants_ of this country, and yet they would not comprehend you, but would persist in ascribing it to supernatural aid.”

“Doctor, you spoke of the first time Europeans visited these regions. Who were the visitors?” inquired Joe.

“My dear fellow, we are now upon the very track of Major Denham. It was at this very city of Mosfeia that he was received by the Sultan of Mandara; he had quitted the Bornou country; he accompanied the sheik in an expedition against the Fellatahs; he assisted in the attack on the city, which, with its arrows alone, bravely resisted the bullets of the Arabs, and put the sheik’s troops to flight. All this was but a pretext for murders, raids, and pillage. The major was completely plundered and stripped, and had it not been for his horse, under whose stomach he clung with the skill of an Indian rider, and was borne with a headlong gallop from his barbarous pursuers, he never could have made his way back to Kouka, the capital of Bornou.”

“Who was this Major Denham?”

“A fearless Englishman, who, between 1822 and 1824, commanded an expedition into the Bornou country, in company with Captain Clapperton and Dr. Oudney. They set out from Tripoli in the month of March, reached Mourzouk, the capital of Fez, and, following the route which at a later period Dr. Barth was to pursue on his way back to Europe, they arrived, on the 16th of February, 1823, at Kouka, near Lake Tchad. Denham made several explorations in Bornou, in Mandara, and to the eastern shores of the lake. In the mean time, on the 15th of December, 1823, Captain Clapperton and Dr. Oudney had pushed their way through the Soudan country as far as Sackatoo, and Oudney died of fatigue and exhaustion in the town of Murmur.”

“This part of Africa has, therefore, paid a heavy tribute of victims to the cause of science,” said Kennedy.

“Yes, this country is fatal to travellers. We are moving directly toward the kingdom of Baghirmi, which Vogel traversed in 1856, so as to reach the Wadai country, where he disappeared. This young man, at the age of twenty-three, had been sent to cooperate with Dr. Barth. They met on the 1st of December, 1854, and thereupon commenced his explorations of the country. Toward 1856, he announced, in the last letters received from him, his intention to reconnoitre the kingdom of Wadai, which no European had yet penetrated. It appears that he got as far as Wara, the capital, where, according to some accounts, he was made prisoner, and, according to others, was put to death for having attempted to ascend a sacred mountain in the environs. But, we must not too lightly admit the death of travellers, since that does away with the necessity of going in search of them. For instance, how often was the death of Dr. Barth reported, to his own great annoyance! It is, therefore, very possible that Vogel may still be held as a prisoner by the Sultan of Wadai, in the hope of obtaining a good ransom for him.

“Baron de Neimans was about starting for the Wadai country when he died at Cairo, in 1855; and we now know that De Heuglin has set out on Vogel’s track with the expedition sent from Leipsic, so that we shall soon be accurately informed as to the fate of that young and interesting explorer.”[4]

[4] Since the doctor’s departure, letters written from El’Obeid by Mr. Muntzinger, the newly-appointed head of the expedition, unfortunately place the death of Vogel beyond a doubt.

Mosfeia had disappeared from the horizon long ere this, and the Mandara country was developing to the gaze of our aëronauts its astonishing fertility, with its forests of acacias, its locust-trees covered with red flowers, and the herbaceous plants of its fields of cotton and indigo trees. The river Shari, which eighty miles farther on rolled its impetuous waters into Lake Tchad, was quite distinctly seen.

The doctor got his companions to trace its course upon the maps drawn by Dr. Barth.

“You perceive,” said he, “that the labors of this _savant_ have been conducted with great precision; we are moving directly toward the Loggoum region, and perhaps toward Kernak, its capital. It was there that poor Toole died, at the age of scarcely twenty-two. He was a young Englishman, an ensign in the 80th regiment, who, a few weeks before, had joined Major Denham in Africa, and it was not long ere he there met his death. Ah! this vast country might well be called the graveyard of European travellers.”

Some boats, fifty feet long, were descending the current of the Shari. The _Victoria_, then one thousand feet above the soil, hardly attracted the attention of the natives; but the wind, which until then had been blowing with a certain degree of strength, was falling off.

“Is it possible that we are to be caught in another dead calm?” sighed the doctor.

“Well, we’ve no lack of water, nor the desert to fear, anyhow, master,” said Joe.

“No; but there are races here still more to be dreaded.”

“Why!” said Joe, again, “there’s something like a town.”

“That is Kernak. The last puffs of the breeze are wafting us to it, and, if we choose, we can take an exact plan of the place.”

“Shall we not go nearer to it?” asked Kennedy.

“Nothing easier, Dick! We are right over it. Allow me to turn the stopcock of the cylinder, and we’ll not be long in descending.”

Half an hour later the balloon hung motionless about two hundred feet from the ground.

“Here we are!” said the doctor, “nearer to Kernak than a man would be to London, if he were perched in the cupola of St. Paul’s. So we can take a survey at our ease.”

“What is that tick-tacking sound that we hear on all sides?”

Joe looked attentively, and at length discovered that the noise they heard was produced by a number of weavers beating cloth stretched in the open air, on large trunks of trees.

The capital of Loggoum could then be seen in its entire extent, like an unrolled chart. It is really a city with straight rows of houses and quite wide streets. In the midst of a large open space there was a slave-market, attended by a great crowd of customers, for the Mandara women, who have extremely small hands and feet, are in excellent request, and can be sold at lucrative rates.

At the sight of the _Victoria_, the scene so often produced occurred again. At first there were outcries, and then followed general stupefaction; business was abandoned; work was flung aside, and all noise ceased. The aëronauts remained as they were, completely motionless, and lost not a detail of the populous city. They even went down to within sixty feet of the ground.

Hereupon the Governor of Loggoum came out from his residence, displaying his green standard, and accompanied by his musicians, who blew on hoarse buffalo-horns, as though they would split their cheeks or any thing else, excepting their own lungs. The crowd at once gathered around him. In the mean while Dr. Ferguson tried to make himself heard, but in vain.

This population looked like proud and intelligent people, with their high foreheads, their almost aquiline noses, and their curling hair; but the presence of the _Victoria_ troubled them greatly. Horsemen could be seen galloping in all directions, and it soon became evident that the governor’s troops were assembling to oppose so extraordinary a foe. Joe wore himself out waving handkerchiefs of every color and shape to them; but his exertions were all to no purpose.

However, the sheik, surrounded by his court, proclaimed silence, and pronounced a discourse, of which the doctor could not understand a word. It was Arabic, mixed with Baghirmi. He could make out enough, however, by the universal language of gestures, to be aware that he was receiving a very polite invitation to depart. Indeed, he would have asked for nothing better, but for lack of wind, the thing had become impossible. His noncompliance, therefore, exasperated the governor, whose courtiers and attendants set up a furious howl to enforce immediate obedience on the part of the aërial monster.

They were odd-looking fellows those courtiers, with their five or six shirts swathed around their bodies! They had enormous stomachs, some of which actually seemed to be artificial. The doctor surprised his companions by informing them that this was the way to pay court to the sultan. The rotundity of the stomach indicated the ambition of its possessor. These corpulent gentry gesticulated and bawled at the top of their voices—one of them particularly distinguishing himself above the rest—to such an extent, indeed, that he must have been a prime minister—at least, if the disturbance he made was any criterion of his rank. The common rabble of dusky denizens united their howlings with the uproar of the court, repeating their gesticulations like so many monkeys, and thereby producing a single and instantaneous movement of ten thousand arms at one time.

To these means of intimidation, which were presently deemed insufficient, were added others still more formidable. Soldiers, armed with bows and arrows, were drawn up in line of battle; but by this time the balloon was expanding, and rising quietly beyond their reach. Upon this the governor seized a musket and aimed it at the balloon; but, Kennedy, who was watching him, shattered the uplifted weapon in the sheik’s grasp.

At this unexpected blow there was a general rout. Every mother’s son of them scampered for his dwelling with the utmost celerity, and stayed there, so that the streets of the town were absolutely deserted for the remainder of that day.

Night came, and not a breath of wind was stirring. The aëronauts had to make up their minds to remain motionless at the distance of but three hundred feet above the ground. Not a fire or light shone in the deep gloom, and around reigned the silence of death; but the doctor only redoubled his vigilance, as this apparent quiet might conceal some snare.

And he had reason to be watchful. About midnight, the whole city seemed to be in a blaze. Hundreds of streaks of flame crossed each other, and shot to and fro in the air like rockets, forming a regular network of fire.

“That’s really curious!” said the doctor, somewhat puzzled to make out what it meant.

“By all that’s glorious!” shouted Kennedy, “it looks as if the fire were ascending and coming up toward us!”

And, sure enough, with an accompaniment of musket-shots, yelling, and din of every description, the mass of fire was, indeed, mounting toward the _Victoria_. Joe got ready to throw out ballast, and Ferguson was not long at guessing the truth. Thousands of pigeons, their tails garnished with combustibles, had been set loose and driven toward the _Victoria;_ and now, in their terror, they were flying high up, zigzagging the atmosphere with lines of fire. Kennedy was preparing to discharge all his batteries into the middle of the ascending multitude, but what could he have done against such a numberless army? The pigeons were already whisking around the car; they were even surrounding the balloon, the sides of which, reflecting their illumination, looked as though enveloped with a network of fire.

The doctor dared hesitate no longer; and, throwing out a fragment of quartz, he kept himself beyond the reach of these dangerous assailants; and, for two hours afterward, he could see them wandering hither and thither through the darkness of the night, until, little by little, their light diminished, and they, one by one, died out.

“Now we may sleep in quiet,” said the doctor.

“Not badly got up for barbarians,” mused friend Joe, speaking his thoughts aloud.

“Oh, they employ these pigeons frequently, to set fire to the thatch of hostile villages; but this time the village mounted higher than they could go.”

“Why, positively, a balloon need fear no enemies!”

“Yes, indeed, it may!” objected Ferguson.

“What are they, then, doctor?”

“They are the careless people in the car! So, my friends, let us have vigilance in all places and at all times.”

CHAPTER THIRTY-FIRST.

Departure in the Night-time.—All Three.—Kennedy’s Instincts.—Precautions.—The Course of the Shari River.—Lake Tchad.—The Water of the Lake.—The Hippopotamus.—One Bullet thrown away.

About three o’clock in the morning, Joe, who was then on watch, at length saw the city move away from beneath his feet. The _Victoria_ was once again in motion, and both the doctor and Kennedy awoke.

The former consulted his compass, and saw, with satisfaction, that the wind was carrying them toward the north-northeast.

“We are in luck!” said he; “every thing works in our favor: we shall discover Lake Tchad this very day.”

“Is it a broad sheet of water?” asked Kennedy.

“Somewhat, Dick. At its greatest length and breadth, it measures about one hundred and twenty miles.”

“It will spice our trip with a little variety to sail over a spacious sheet of water.”

“After all, though, I don’t see that we have much to complain of on that score. Our trip has been very much varied, indeed; and, moreover, we are getting on under the best possible conditions.”

“Unquestionably so; excepting those privations on the desert, we have encountered no serious danger.”

“It is not to be denied that our noble balloon has behaved wonderfully well. To-day is May 12th, and we started on the 18th of April. That makes twenty-five days of journeying. In ten days more we shall have reached our destination.”

“Where is that?”

“I do not know. But what does that signify?”

“You are right again, Samuel! Let us intrust to Providence the care of guiding us and of keeping us in good health as we are now. We don’t look much as though we had been crossing the most pestilential country in the world!”

“We had an opportunity of getting up in life, and that’s what we have done!”

“Hurrah for trips in the air!” cried Joe. “Here we are at the end of twenty-five days in good condition, well fed, and well rested. We’ve had too much rest in fact, for my legs begin to feel rusty, and I wouldn’t be vexed a bit to stretch them with a run of thirty miles or so!”

“You can do that, Joe, in the streets of London, but in fine we set out three together, like Denham, Clapperton, and Overweg; like Barth, Richardson, and Vogel, and, more fortunate than our predecessors here, we are three in number still. But it is most important for us not to separate. If, while one of us was on the ground, the _Victoria_ should have to ascend in order to escape some sudden danger, who knows whether we should ever see each other again? Therefore it is that I say again to Kennedy frankly that I do not like his going off alone to hunt.”

“But still, Samuel, you will permit me to indulge that fancy a little. There is no harm in renewing our stock of provisions. Besides, before our departure, you held out to me the prospect of some superb hunting, and thus far I have done but little in the line of the Andersons and Cummings.”

“But, my dear Dick, your memory fails you, or your modesty makes you forget your own exploits. It really seems to me that, without mentioning small game, you have already an antelope, an elephant, and two lions on your conscience.”

“But what’s all that to an African sportsman who sees all the animals in creation strutting along under the muzzle of his rifle? There! there! look at that troop of giraffes!”

“Those giraffes,” roared Joe; “why, they’re not as big as my fist.”

“Because we are a thousand feet above them; but close to them you would discover that they are three times as tall as you are!”

“And what do you say to yon herd of gazelles, and those ostriches, that run with the speed of the wind?” resumed Kennedy.

“Those ostriches?” remonstrated Joe, again; “those are chickens, and the greatest kind of chickens!”

“Come, doctor, can’t we get down nearer to them?” pleaded Kennedy.

“We can get closer to them, Dick, but we must not land. And what good will it do you to strike down those poor animals when they can be of no use to you? Now, if the question were to destroy a lion, a tiger, a cat, a hyena, I could understand it; but to deprive an antelope or a gazelle of life, to no other purpose than the gratification of your instincts as a sportsman, seems hardly worth the trouble. But, after all, my friend, we are going to keep at about one hundred feet only from the soil, and, should you see any ferocious wild beast, oblige us by sending a ball through its heart!”

The _Victoria_ descended gradually, but still keeping at a safe height, for, in a barbarous, yet very populous country, it was necessary to keep on the watch for unexpected perils.

The travellers were then directly following the course of the Shari. The charming banks of this river were hidden beneath the foliage of trees of various dyes; lianas and climbing plants wound in and out on all sides and formed the most curious combinations of color. Crocodiles were seen basking in the broad blaze of the sun or plunging beneath the waters with the agility of lizards, and in their gambols they sported about among the many green islands that intercept the current of the stream.

It was thus, in the midst of rich and verdant landscapes that our travellers passed over the district of Maffatay, and about nine o’clock in the morning reached the southern shore of Lake Tchad.

There it was at last, outstretched before them, that Caspian Sea of Africa, the existence of which was so long consigned to the realms of fable—that interior expanse of water to which only Denham’s and Barth’s expeditions had been able to force their way.

The doctor strove in vain to fix its precise configuration upon paper. It had already changed greatly since 1847. In fact, the chart of Lake Tchad is very difficult to trace with exactitude, for it is surrounded by muddy and almost impassable morasses, in which Barth thought that he was doomed to perish. From year to year these marshes, covered with reeds and papyrus fifteen feet high, become the lake itself. Frequently, too, the villages on its shores are half submerged, as was the case with Ngornou in 1856, and now the hippopotamus and the alligator frisk and dive where the dwellings of Bornou once stood.

The sun shot his dazzling rays over this placid sheet of water, and toward the north the two elements merged into one and the same horizon.

The doctor was desirous of determining the character of the water, which was long believed to be salt. There was no danger in descending close to the lake, and the car was soon skimming its surface like a bird at the distance of only five feet.

Joe plunged a bottle into the lake and drew it up half filled. The water was then tasted and found to be but little fit for drinking, with a certain carbonate-of-soda flavor.

While the doctor was jotting down the result of this experiment, the loud report of a gun was heard close beside him. Kennedy had not been able to resist the temptation of firing at a huge hippopotamus. The latter, who had been basking quietly, disappeared at the sound of the explosion, but did not seem to be otherwise incommoded by Kennedy’s conical bullet.

“You’d have done better if you had harpooned him,” said Joe.

“But how?”

“With one of our anchors. It would have been a hook just big enough for such a rousing beast as that!”

“Humph!” ejaculated Kennedy, “Joe really has an idea this time—”

“Which I beg of you not to put into execution,” interposed the doctor. “The animal would very quickly have dragged us where we could not have done much to help ourselves, and where we have no business to be.”

“Especially now since we’ve settled the question as to what kind of water there is in Lake Tchad. Is that sort of fish good to eat, Dr. Ferguson?”

“That fish, as you call it, Joe, is really a mammiferous animal of the pachydermal species. Its flesh is said to be excellent and is an article of important trade between the tribes living along the borders of the lake.”

“Then I’m sorry that Mr. Kennedy’s shot didn’t do more damage.”

“The animal is vulnerable only in the stomach and between the thighs. Dick’s ball hasn’t even marked him; but should the ground strike me as favorable, we shall halt at the northern end of the lake, where Kennedy will find himself in the midst of a whole menagerie, and can make up for lost time.”

“Well,” said Joe, “I hope then that Mr. Kennedy will hunt the hippopotamus a little; I’d like to taste the meat of that queer-looking beast. It doesn’t look exactly natural to get away into the centre of Africa, to feed on snipe and partridge, just as if we were in England.”

CHAPTER THIRTY-SECOND.

The Capital of Bornou.—The Islands of the Biddiomahs.—The Condors.—The Doctor’s Anxieties.—His Precautions.—An Attack in Mid-air.—The Balloon Covering torn.—The Fall.—Sublime Self-Sacrifice.—The Northern Coast of the Lake.

Since its arrival at Lake Tchad, the balloon had struck a current that edged it farther to the westward. A few clouds tempered the heat of the day, and, besides, a little air could be felt over this vast expanse of water; but about one o’clock, the _Victoria_, having slanted across this part of the lake, again advanced over the land for a space of seven or eight miles.

The doctor, who was somewhat vexed at first at this turn of his course, no longer thought of complaining when he caught sight of the city of Kouka, the capital of Bornou. He saw it for a moment, encircled by its walls of white clay, and a few rudely-constructed mosques rising clumsily above that conglomeration of houses that look like playing-dice, which form most Arab towns. In the court-yards of the private dwellings, and on the public squares, grew palms and caoutchouc-trees topped with a dome of foliage more than one hundred feet in breadth. Joe called attention to the fact that these immense parasols were in proper accordance with the intense heat of the sun, and made thereon some pious reflections which it were needless to repeat.

Kouka really consists of two distinct towns, separated by the “Dendal,” a large boulevard three hundred yards wide, at that hour crowded with horsemen and foot passengers. On one side, the rich quarter stands squarely with its airy and lofty houses, laid out in regular order; on the other, is huddled together the poor quarter, a miserable collection of low hovels of a conical shape, in which a poverty-stricken multitude vegetate rather than live, since Kouka is neither a trading nor a commercial city.

Kennedy thought it looked something like Edinburgh, were that city extended on a plain, with its two distinct boroughs.

But our travellers had scarcely the time to catch even this glimpse of it, for, with the fickleness that characterizes the air-currents of this region, a contrary wind suddenly swept them some forty miles over the surface of Lake Tchad.

Then then were regaled with a new spectacle. They could count the numerous islets of the lake, inhabited by the Biddiomahs, a race of bloodthirsty and formidable pirates, who are as greatly feared when neighbors as are the Touaregs of Sahara.

These estimable people were in readiness to receive the _Victoria_ bravely with stones and arrows, but the balloon quickly passed their islands, fluttering over them, from one to the other with butterfly motion, like a gigantic beetle.

At this moment, Joe, who was scanning the horizon, said to Kennedy:

“There, sir, as you are always thinking of good sport, yonder is just the thing for you!”

“What is it, Joe?”

“This time, the doctor will not disapprove of your shooting.”

“But what is it?”

“Don’t you see that flock of big birds making for us?”

“Birds?” exclaimed the doctor, snatching his spy-glass.

“I see them,” replied Kennedy; “there are at least a dozen of them.”

“Fourteen, exactly!” said Joe.

“Heaven grant that they may be of a kind sufficiently noxious for the doctor to let me peg away at them!”

“I should not object, but I would much rather see those birds at a distance from us!”

“Why, are you afraid of those fowls?”

“They are condors, and of the largest size. Should they attack us—”

“Well, if they do, we’ll defend ourselves. We have a whole arsenal at our disposal. I don’t think those birds are so very formidable.”

“Who can tell?” was the doctor’s only remark.

Ten minutes later, the flock had come within gunshot, and were making the air ring with their hoarse cries. They came right toward the _Victoria_, more irritated than frightened by her presence.

“How they scream! What a noise!” said Joe.

“Perhaps they don’t like to see anybody poaching in their country up in the air, or daring to fly like themselves!”

“Well, now, to tell the truth, when I take a good look at them, they are an ugly, ferocious set, and I should think them dangerous enough if they were armed with Purdy-Moore rifles,” admitted Kennedy.

“They have no need of such weapons,” said Ferguson, looking very grave.

The condors flew around them in wide circles, their flight growing gradually closer and closer to the balloon. They swept through the air in rapid, fantastic curves, occasionally precipitating themselves headlong with the speed of a bullet, and then breaking their line of projection by an abrupt and daring angle.

The doctor, much disquieted, resolved to ascend so as to escape this dangerous proximity. He therefore dilated the hydrogen in his balloon, and it rapidly rose.

But the condors mounted with him, apparently determined not to part company.

“They seem to mean mischief!” said the hunter, cocking his rifle.

And, in fact, they were swooping nearer, and more than one came within fifty feet of them, as if defying the fire-arms.

“By George, I’m itching to let them have it!” exclaimed Kennedy.

“No, Dick; not now! Don’t exasperate them needlessly. That would only be exciting them to attack us!”

“But I could soon settle those fellows!”

“You may think so, Dick. But you are wrong!”

“Why, we have a bullet for each of them!”

“And suppose that they were to attack the upper part of the balloon, what would you do? How would you get at them? Just imagine yourself in the presence of a troop of lions on the plain, or a school of sharks in the open ocean! For travellers in the air, this situation is just as dangerous.”

“Are you speaking seriously, doctor?”

“Very seriously, Dick.”

“Let us wait, then!”

“Wait! Hold yourself in readiness in case of an attack, but do not fire without my orders.”

The birds then collected at a short distance, yet so near that their naked necks, entirely bare of feathers, could be plainly seen, as they stretched them out with the effort of their cries, while their gristly crests, garnished with a comb and gills of deep violet, stood erect with rage. They were of the very largest size, their bodies being more than three feet in length, and the lower surface of their white wings glittering in the sunlight. They might well have been considered winged sharks, so striking was their resemblance to those ferocious rangers of the deep.

“They are following us!” said the doctor, as he saw them ascending with him, “and, mount as we may, they can fly still higher!”

“Well, what are we to do?” asked Kennedy.

The doctor made no answer.

“Listen, Samuel!” said the sportsman. “There are fourteen of those birds; we have seventeen shots at our disposal if we discharge all our weapons. Have we not the means, then, to destroy them or disperse them? I will give a good account of some of them!”

“I have no doubt of your skill, Dick; I look upon all as dead that may come within range of your rifle, but I repeat that, if they attack the upper part of the balloon, you could not get a sight at them. They would tear the silk covering that sustains us, and we are three thousand feet up in the air!”

At this moment, one of the ferocious birds darted right at the balloon, with outstretched beak and claws, ready to rend it with either or both.

“Fire! fire at once!” cried the doctor.

He had scarcely ceased, ere the huge creature, stricken dead, dropped headlong, turning over and over in space as he fell.

Kennedy had already grasped one of the two-barrelled fowling-pieces and Joe was taking aim with another.

Frightened by the report, the condors drew back for a moment, but they almost instantly returned to the charge with extreme fury. Kennedy severed the head of one from its body with his first shot, and Joe broke the wing of another.

“Only eleven left,” said he.

Thereupon the birds changed their tactics, and by common consent soared above the balloon. Kennedy glanced at Ferguson. The latter, in spite of his imperturbability, grew pale. Then ensued a moment of terrifying silence. In the next they heard a harsh tearing noise, as of something rending the silk, and the car seemed to sink from beneath the feet of our three aëronauts.

“We are lost!” exclaimed Ferguson, glancing at the barometer, which was now swiftly rising.

“Over with the ballast!” he shouted, “over with it!”

And in a few seconds the last lumps of quartz had disappeared.

“We are still falling! Empty the water-tanks! Do you hear me, Joe? We are pitching into the lake!”

Joe obeyed. The doctor leaned over and looked out. The lake seemed to come up toward him like a rising tide. Every object around grew rapidly in size while they were looking at it. The car was not two hundred feet from the surface of Lake Tchad.

“The provisions! the provisions!” cried the doctor.

And the box containing them was launched into space.

Their descent became less rapid, but the luckless aëronauts were still falling, and into the lake.

“Throw out something—something more!” cried the doctor.

“There is nothing more to throw!” was Kennedy’s despairing response.

“Yes, there is!” called Joe, and with a wave of the hand he disappeared like a flash, over the edge of the car.

“Joe! Joe!” exclaimed the doctor, horror-stricken.

The _Victoria_ thus relieved resumed her ascending motion, mounted a thousand feet into the air, and the wind, burying itself in the disinflated covering, bore them away toward the northern part of the lake.

“Lost!” exclaimed the sportsman, with a gesture of despair.

“Lost to save us!” responded Ferguson.

And these men, intrepid as they were, felt the large tears streaming down their cheeks. They leaned over with the vain hope of seeing some trace of their heroic companion, but they were already far away from him.

“What course shall we pursue?” asked Kennedy.

“Alight as soon as possible, Dick, and then wait.”

After a sweep of some sixty miles the _Victoria_ halted on a desert shore, on the north of the lake. The anchors caught in a low tree and the sportsman fastened it securely. Night came, but neither Ferguson nor Kennedy could find one moment’s sleep.

CHAPTER THIRTY-THIRD.

Conjectures.—Reestablishment of the Victoria’s Equilibrium.—Dr. Ferguson’s New Calculations.—Kennedy’s Hunt.—A Complete Exploration of Lake Tchad.—Tangalia.—The Return.—Lari.

On the morrow, the 13th of May, our travellers, for the first time, reconnoitred the part of the coast on which they had landed. It was a sort of island of solid ground in the midst of an immense marsh. Around this fragment of _terra firma_ grew reeds as lofty as trees are in Europe, and stretching away out of sight.

These impenetrable swamps gave security to the position of the balloon. It was necessary to watch only the borders of the lake. The vast stretch of water broadened away from the spot, especially toward the east, and nothing could be seen on the horizon, neither mainland nor islands.

The two friends had not yet ventured to speak of their recent companion. Kennedy first imparted his conjectures to the doctor.

“Perhaps Joe is not lost after all,” he said. “He was a skilful lad, and had few equals as a swimmer. He would find no difficulty in swimming across the Firth of Forth at Edinburgh. We shall see him again—but how and where I know not. Let us omit nothing on our part to give him the chance of rejoining us.”

“May God grant it as you say, Dick!” replied the doctor, with much emotion. “We shall do everything in the world to find our lost friend again. Let us, in the first place, see where we are. But, above all things, let us rid the _Victoria_ of this outside covering, which is of no further use. That will relieve us of six hundred and fifty pounds, a weight not to be despised—and the end is worth the trouble!”

The doctor and Kennedy went to work at once, but they encountered great difficulty. They had to tear the strong silk away piece by piece, and then cut it in narrow strips so as to extricate it from the meshes of the network. The tear made by the beaks of the condors was found to be several feet in length.

This operation took at least four hours, but at length the inner balloon once completely extricated did not appear to have suffered in the least degree. The _Victoria_ was thus diminished in size by one fifth, and this difference was sufficiently noticeable to excite Kennedy’s surprise.

“Will it be large enough?” he asked.

“Have no fears on that score, I will reestablish the equilibrium, and should our poor Joe return we shall find a way to start off with him again on our old route.”

“At the moment of our fall, unless I am mistaken, we were not far from an island.”

“Yes, I recollect it,” said the doctor, “but that island, like all the islands on Lake Tchad, is, no doubt, inhabited by a gang of pirates and murderers. They certainly witnessed our misfortune, and should Joe fall into their hands, what will become of him unless protected by their superstitions?”

“Oh, he’s just the lad to get safely out of the scrape, I repeat. I have great confidence in his shrewdness and skill.”

“I hope so. Now, Dick, you may go and hunt in the neighborhood, but don’t get far away whatever you do. It has become a pressing necessity for us to renew our stock of provisions, since we had to sacrifice nearly all the old lot.”

“Very good, doctor, I shall not be long absent.”

Hereupon, Kennedy took a double-barrelled fowling-piece, and strode through the long grass toward a thicket not far off, where the frequent sound of shooting soon let the doctor know that the sportsman was making a good use of his time.

Meanwhile Ferguson was engaged in calculating the relative weight of the articles still left in the car, and in establishing the equipoise of the second balloon. He found that there were still left some thirty pounds of pemmican, a supply of tea and coffee, about a gallon and a half of brandy, and one empty water-tank. All the dried meat had disappeared.

The doctor was aware that, by the loss of the hydrogen in the first balloon, the ascensional force at his disposal was now reduced to about nine hundred pounds. He therefore had to count upon this difference in order to rearrange his equilibrium. The new balloon measured sixty-seven thousand cubic feet, and contained thirty-three thousand four hundred and eighty feet of gas. The dilating apparatus appeared to be in good condition, and neither the battery nor the spiral had been injured.

The ascensional force of the new balloon was then about three thousand pounds, and, in adding together the weight of the apparatus, of the passengers, of the stock of water, of the car and its accessories, and putting aboard fifty gallons of water, and one hundred pounds of fresh meat, the doctor got a total weight of twenty-eight hundred and thirty pounds. He could then take with him one hundred and seventy pounds of ballast, for unforeseen emergencies, and the balloon would be in exact balance with the surrounding atmosphere.

His arrangements were completed accordingly, and he made up for Joe’s weight with a surplus of ballast. He spent the whole day in these preparations, and the latter were finished when Kennedy returned. The hunter had been successful, and brought back a regular cargo of geese, wild-duck, snipe, teal, and plover. He went to work at once to draw and smoke the game. Each piece, suspended on a small, thin skewer, was hung over a fire of green wood. When they seemed in good order, Kennedy, who was perfectly at home in the business, packed them away in the car.

On the morrow, the hunter was to complete his supplies.

Evening surprised our travellers in the midst of this work. Their supper consisted of pemmican, biscuit, and tea; and fatigue, after having given them appetite, brought them sleep. Each of them strained eyes and ears into the gloom during his watch, sometimes fancying that they heard the voice of poor Joe; but, alas! the voice that they so longed to hear, was far away.

At the first streak of day, the doctor aroused Kennedy.

“I have been long and carefully considering what should be done,” said he, “to find our companion.”

“Whatever your plan may be, doctor, it will suit me. Speak!”

“Above all things, it is important that Joe should hear from us in some way.”

“Undoubtedly. Suppose the brave fellow should take it into his head that we have abandoned him?”

“He! He knows us too well for that. Such a thought would never come into his mind. But he must be informed as to where we are.”

“How can that be managed?”

“We shall get into our car and be off again through the air.”

“But, should the wind bear us away?”

“Happily, it will not. See, Dick! it is carrying us back to the lake; and this circumstance, which would have been vexatious yesterday, is fortunate now. Our efforts, then, will be limited to keeping ourselves above that vast sheet of water throughout the day. Joe cannot fail to see us, and his eyes will be constantly on the lookout in that direction. Perhaps he will even manage to let us know the place of his retreat.”

“If he be alone and at liberty, he certainly will.”

“And if a prisoner,” resumed the doctor, “it not being the practice of the natives to confine their captives, he will see us, and comprehend the object of our researches.”

“But, at last,” put in Kennedy—“for we must anticipate every thing—should we find no trace—if he should have left no mark to follow him by, what are we to do?”

“We shall endeavor to regain the northern part of the lake, keeping ourselves as much in sight as possible. There we’ll wait; we’ll explore the banks; we’ll search the water’s edge, for Joe will assuredly try to reach the shore; and we will not leave the country without having done every thing to find him.”

“Let us set out, then!” said the hunter.

The doctor hereupon took the exact bearings of the patch of solid land they were about to leave, and arrived at the conclusion that it lay on the north shore of Lake Tchad, between the village of Lari and the village of Ingemini, both visited by Major Denham. During this time Kennedy was completing his stock of fresh meat. Although the neighboring marshes showed traces of the rhinoceros, the lamantine (or _manatee_), and the hippopotamus, he had no opportunity to see a single specimen of those animals.

At seven in the morning, but not without great difficulty—which to Joe would have been nothing—the balloon’s anchor was detached from its hold, the gas dilated, and the new _Victoria_ rose two hundred feet into the air. It seemed to hesitate at first, and went spinning around, like a top; but at last a brisk current caught it, and it advanced over the lake, and was soon borne away at a speed of twenty miles per hour.

The doctor continued to keep at a height of from two hundred to five hundred feet. Kennedy frequently discharged his rifle; and, when passing over islands, the aëronauts approached them even imprudently, scrutinizing the thickets, the bushes, the underbrush—in fine, every spot where a mass of shade or jutting rock could have afforded a retreat to their companion. They swooped down close to the long pirogues that navigated the lake; and the wild fishermen, terrified at the sight of the balloon, would plunge into the water and regain their islands with every symptom of undisguised affright.

“We can see nothing,” said Kennedy, after two hours of search.

“Let us wait a little longer, Dick, and not lose heart. We cannot be far away from the scene of our accident.”

By eleven o’clock the balloon had gone ninety miles. It then fell in with a new current, which, blowing almost at right angles to the other, drove them eastward about sixty miles. It next floated over a very large and populous island, which the doctor took to be Farram, on which the capital of the Biddiomahs is situated. Ferguson expected at every moment to see Joe spring up out of some thicket, flying for his life, and calling for help. Were he free, they could pick him up without trouble; were he a prisoner, they could rescue him by repeating the manœuvre they had practised to save the missionary, and he would soon be with his friends again; but nothing was seen, not a sound was heard. The case seemed desperate.

About half-past two o’clock, the _Victoria_ hove in sight of Tangalia, a village situated on the eastern shore of Lake Tchad, where it marks the extreme point attained by Denham at the period of his exploration.

The doctor became uneasy at this persistent setting of the wind in that direction, for he felt that he was being thrown back to the eastward, toward the centre of Africa, and the interminable deserts of that region.

“We must absolutely come to a halt,” said he, “and even alight. For Joe’s sake, particularly, we ought to go back to the lake; but, to begin with, let us endeavor to find an opposite current.”

During more than an hour he searched at different altitudes: the balloon always came back toward the mainland. But at length, at the height of a thousand feet, a very violent breeze swept to the northwestward.

It was out of the question that Joe should have been detained on one of the islands of the lake; for, in such case he would certainly have found means to make his presence there known. Perhaps he had been dragged to the mainland. The doctor was reasoning thus to himself, when he again came in sight of the northern shore of Lake Tchad.

As for supposing that Joe had been drowned, that was not to be believed for a moment. One horrible thought glanced across the minds of both Kennedy and the doctor: caymans swarm in these waters! But neither one nor the other had the courage to distinctly communicate this impression. However, it came up to them so forcibly at last that the doctor said, without further preface:

“Crocodiles are found only on the shores of the islands or of the lake, and Joe will have skill enough to avoid them. Besides, they are not very dangerous; and the Africans bathe with impunity, and quite fearless of their attacks.”

Kennedy made no reply. He preferred keeping quiet to discussing this terrible possibility.

The doctor made out the town of Lari about five o’clock in the evening. The inhabitants were at work gathering in their cotton-crop in front of their huts, constructed of woven reeds, and standing in the midst of clean and neatly-kept enclosures. This collection of about fifty habitations occupied a slight depression of the soil, in a valley extending between two low mountains. The force of the wind carried the doctor farther onward than he wanted to go; but it changed a second time, and bore him back exactly to his starting-point, on the sort of enclosed island where he had passed the preceding night. The anchor, instead of catching the branches of the tree, took hold in the masses of reeds mixed with the thick mud of the marshes, which offered considerable resistance.

The doctor had much difficulty in restraining the balloon; but at length the wind died away with the setting in of nightfall; and the two friends kept watch together in an almost desperate state of mind.

CHAPTER THIRTY-FOURTH.

The Hurricane.—A Forced Departure.—Loss of an Anchor.—Melancholy Reflections.—The Resolution adopted.—The Sand-Storm.—The Buried Caravan.—A Contrary yet Favorable Wind.—The Return southward.—Kennedy at his Post.

At three o’clock in the morning the wind was raging. It beat down with such violence that the _Victoria_ could not stay near the ground without danger. It was thrown almost flat over upon its side, and the reeds chafed the silk so roughly that it seemed as though they would tear it.

“We must be off, Dick,” said the doctor; “we cannot remain in this situation.”

“But, doctor, what of Joe?”

“I am not likely to abandon him. No, indeed! and should the hurricane carry me a thousand miles to the northward, I will return! But here we are endangering the safety of all.”

“Must we go without him?” asked the Scot, with an accent of profound grief.

“And do you think, then,” rejoined Ferguson, “that my heart does not bleed like your own? Am I not merely obeying an imperious necessity?”

“I am entirely at your orders,” replied the hunter; “let us start!”

But their departure was surrounded with unusual difficulty. The anchor, which had caught very deeply, resisted all their efforts to disengage it; while the balloon, drawing in the opposite direction, increased its tension. Kennedy could not get it free. Besides, in his present position, the manœuvre had become a very perilous one, for the _Victoria_ threatened to break away before he should be able to get into the car again.

The doctor, unwilling to run such a risk, made his friend get into his place, and resigned himself to the alternative of cutting the anchor-rope. The _Victoria_ made one bound of three hundred feet into the air, and took her route directly northward.

Ferguson had no other choice than to scud before the storm. He folded his arms, and soon became absorbed in his own melancholy reflections.

After a few moments of profound silence, he turned to Kennedy, who sat there no less taciturn.

“We have, perhaps, been tempting Providence,” said he; “it does not belong to man to undertake such a journey!”—and a sigh of grief escaped him as he spoke.

“It is but a few days,” replied the sportsman, “since we were congratulating ourselves upon having escaped so many dangers! All three of us were shaking hands!”

“Poor Joe! kindly and excellent disposition! brave and candid heart! Dazzled for a moment by his sudden discovery of wealth, he willingly sacrificed his treasures! And now, he is far from us; and the wind is carrying us still farther away with resistless speed!”

“Come, doctor, admitting that he may have found refuge among the lake tribes, can he not do as the travellers who visited them before us, did;—like Denham, like Barth? Both of those men got back to their own country.”

“Ah! my dear Dick! Joe doesn’t know one word of the language; he is alone, and without resources. The travellers of whom you speak did not attempt to go forward without sending many presents in advance of them to the chiefs, and surrounded by an escort armed and trained for these expeditions. Yet, they could not avoid sufferings of the worst description! What, then, can you expect the fate of our companion to be? It is horrible to think of, and this is one of the worst calamities that it has ever been my lot to endure!”

“But, we’ll come back again, doctor!”

“Come back, Dick? Yes, if we have to abandon the balloon! if we should be forced to return to Lake Tchad on foot, and put ourselves in communication with the Sultan of Bornou! The Arabs cannot have retained a disagreeable remembrance of the first Europeans.”

“I will follow you, doctor,” replied the hunter, with emphasis. “You may count upon me! We would rather give up the idea of prosecuting this journey than not return. Joe forgot himself for our sake; we will sacrifice ourselves for his!”

This resolve revived some hope in the hearts of these two men; they felt strong in the same inspiration. Ferguson forthwith set every thing at work to get into a contrary current, that might bring him back again to Lake Tchad; but this was impracticable at that moment, and even to alight was out of the question on ground completely bare of trees, and with such a hurricane blowing.

The _Victoria_ thus passed over the country of the Tibbous, crossed the Belad el Djerid, a desert of briers that forms the border of the Soudan, and advanced into the desert of sand streaked with the long tracks of the many caravans that pass and repass there. The last line of vegetation was speedily lost in the dim southern horizon, not far from the principal oasis in this part of Africa, whose fifty wells are shaded by magnificent trees; but it was impossible to stop. An Arab encampment, tents of striped stuff, some camels, stretching out their viper-like heads and necks along the sand, gave life to this solitude, but the _Victoria_ sped by like a shooting-star, and in this way traversed a distance of sixty miles in three hours, without Ferguson being able to check or guide her course.

“We cannot halt, we cannot alight!” said the doctor; “not a tree, not an inequality of the ground! Are we then to be driven clear across Sahara? Surely, Heaven is indeed against us!”

He was uttering these words with a sort of despairing rage, when suddenly he saw the desert sands rising aloft in the midst of a dense cloud of dust, and go whirling through the air, impelled by opposing currents.

Amid this tornado, an entire caravan, disorganized, broken, and overthrown, was disappearing beneath an avalanche of sand. The camels, flung pell-mell together, were uttering dull and pitiful groans; cries and howls of despair were heard issuing from that dusty and stifling cloud, and, from time to time, a parti-colored garment cut the chaos of the scene with its vivid hues, and the moaning and shrieking sounded over all, a terrible accompaniment to this spectacle of destruction.

Ere long the sand had accumulated in compact masses; and there, where so recently stretched a level plain as far as the eye could see, rose now a ridgy line of hillocks, still moving from beneath—the vast tomb of an entire caravan!

The doctor and Kennedy, pallid with emotion, sat transfixed by this fearful spectacle. They could no longer manage their balloon, which went whirling round and round in contending currents, and refused to obey the different dilations of the gas. Caught in these eddies of the atmosphere, it spun about with a rapidity that made their heads reel, while the car oscillated and swung to and fro violently at the same time. The instruments suspended under the awning clattered together as though they would be dashed to pieces; the pipes of the spiral bent to and fro, threatening to break at every instant; and the water-tanks jostled and jarred with tremendous din. Although but two feet apart, our aëronauts could not hear each other speak, but with firmly-clinched hands they clung convulsively to the cordage, and endeavored to steady themselves against the fury of the tempest.

Kennedy, with his hair blown wildly about his face, looked on without speaking; but the doctor had regained all his daring in the midst of this deadly peril, and not a sign of his emotion was betrayed in his countenance, even when, after a last violent twirl, the _Victoria_ stopped suddenly in the midst of a most unlooked-for calm; the north wind had abruptly got the upper hand, and now drove her back with equal rapidity over the route she had traversed in the morning.

“Whither are we going now?” cried Kennedy.

“Let us leave that to Providence, my dear Dick; I was wrong in doubting it. It knows better than we, and here we are, returning to places that we had expected never to see again!”

The surface of the country, which had looked so flat and level when they were coming, now seemed tossed and uneven, like the ocean-billows after a storm; a long succession of hillocks, that had scarcely settled to their places yet, indented the desert; the wind blew furiously, and the balloon fairly flew through the atmosphere.

The direction taken by our aëronauts differed somewhat from that of the morning, and thus about nine o’clock, instead of finding themselves again near the borders of Lake Tchad, they saw the desert still stretching away before them.

Kennedy remarked the circumstance.

“It matters little,” replied the doctor, “the important point is to return southward; we shall come across the towns of Bornou, Wouddie, or Kouka, and I should not hesitate to halt there.”

“If you are satisfied, I am content,” replied the Scot, “but Heaven grant that we may not be reduced to cross the desert, as those unfortunate Arabs had to do! What we saw was frightful!”

“It often happens, Dick; these trips across the desert are far more perilous than those across the ocean. The desert has all the dangers of the sea, including the risk of being swallowed up, and added thereto are unendurable fatigues and privations.”

“I think the wind shows some symptoms of moderating; the sand-dust is less dense; the undulations of the surface are diminishing, and the sky is growing clearer.”

“So much the better! We must now reconnoitre attentively with our glasses, and take care not to omit a single point.”

“I will look out for that, doctor, and not a tree shall be seen without my informing you of it.”

And, suiting the action to the word, Kennedy took his station, spy-glass in hand, at the forward part of the car.

CHAPTER THIRTY-FIFTH.

What happened to Joe.—The Island of the Biddiomahs.—The Adoration shown him.—The Island that sank.—The Shores of the Lake.—The Tree of the Serpents.—The Foot-Tramp.—Terrible Suffering.—Mosquitoes and Ants.—Hunger.—The Victoria seen.—She disappears.—The Swamp.—One Last Despairing Cry.

What had become of Joe, while his master was thus vainly seeking for him?

When he had dashed headlong into the lake, his first movement on coming to the surface was to raise his eyes and look upward. He saw the _Victoria_ already risen far above the water, still rapidly ascending and growing smaller and smaller. It was soon caught in a rapid current and disappeared to the northward. His master—both his friends were saved!

“How lucky it was,” thought he, “that I had that idea to throw myself out into the lake! Mr. Kennedy would soon have jumped at it, and he would not have hesitated to do as I did, for nothing’s more natural than for one man to give himself up to save two others. That’s mathematics!”

Satisfied on this point, Joe began to think of himself. He was in the middle of a vast lake, surrounded by tribes unknown to him, and probably ferocious. All the greater reason why he should get out of the scrape by depending only on himself. And so he gave himself no farther concern about it.

Before the attack by the birds of prey, which, according to him, had behaved like real condors, he had noticed an island on the horizon, and determining to reach it, if possible, he put forth all his knowledge and skill in the art of swimming, after having relieved himself of the most troublesome part of his clothing. The idea of a stretch of five or six miles by no means disconcerted him; and therefore, so long as he was in the open lake, he thought only of striking out straight ahead and manfully.

In about an hour and a half the distance between him and the island had greatly diminished.

But as he approached the land, a thought, at first fleeting and then tenacious, arose in his mind. He knew that the shores of the lake were frequented by huge alligators, and was well aware of the voracity of those monsters.

Now, no matter how much he was inclined to find every thing in this world quite natural, the worthy fellow was no little disturbed by this reflection. He feared greatly lest white flesh like his might be particularly acceptable to the dreaded brutes, and advanced only with extreme precaution, his eyes on the alert on both sides and all around him. At length, he was not more than one hundred yards from a bank, covered with green trees, when a puff of air strongly impregnated with a musky odor reached him.

“There!” said he to himself, “just what I expected. The crocodile isn’t far off!”

With this he dived swiftly, but not sufficiently so to avoid coming into contact with an enormous body, the scaly surface of which scratched him as he passed. He thought himself lost and swam with desperate energy. Then he rose again to the top of the water, took breath and dived once more. Thus passed a few minutes of unspeakable anguish, which all his philosophy could not overcome, for he thought, all the while, that he heard behind him the sound of those huge jaws ready to snap him up forever. In this state of mind he was striking out under the water as noiselessly as possible when he felt himself seized by the arm and then by the waist.

Poor Joe! he gave one last thought to his master; and began to struggle with all the energy of despair, feeling himself the while drawn along, but not toward the bottom of the lake, as is the habit of the crocodile when about to devour its prey, but toward the surface.

So soon as he could get breath and look around him, he saw that he was between two natives as black as ebony, who held him, with a firm grip, and uttered strange cries.

“Ha!” said Joe, “blacks instead of crocodiles! Well, I prefer it as it is; but how in the mischief dare these fellows go in bathing in such places?”

Joe was not aware that the inhabitants of the islands of Lake Tchad, like many other negro tribes, plunge with impunity into sheets of water infested with crocodiles and caymans, and without troubling their heads about them. The amphibious denizens of this lake enjoy the well-deserved reputation of being quite inoffensive.

But had not Joe escaped one peril only to fall into another? That was a question which he left events to decide; and, since he could not do otherwise, he allowed himself to be conducted to the shore without manifesting any alarm.

“Evidently,” thought he, “these chaps saw the _Victoria_ skimming the waters of the lake, like a monster of the air. They were the distant witnesses of my tumble, and they can’t fail to have some respect for a man that fell from the sky! Let them have their own way, then.”

Joe was at this stage of his meditations, when he was landed amid a yelling crowd of both sexes, and all ages and sizes, but not of all colors. In fine, he was surrounded by a tribe of Biddiomahs as black as jet. Nor had he to blush for the scantiness of his costume, for he saw that he was in “undress” in the highest style of that country.

But before he had time to form an exact idea of the situation, there was no mistaking the agitation of which he instantly became the object, and this soon enabled him to pluck up courage, although the adventure of Kazeh did come back rather vividly to his memory.

“I foresee that they are going to make a god of me again,” thought he, “some son of the moon most likely. Well, one trade’s as good as another when a man has no choice. The main thing is to gain time. Should the _Victoria_ pass this way again, I’ll take advantage of my new position to treat my worshippers here to a miracle when I go sailing up into the sky!”

While Joe’s thoughts were running thus, the throng pressed around him. They prostrated themselves before him; they howled; they felt him; they became even annoyingly familiar; but at the same time they had the consideration to offer him a superb banquet consisting of sour milk and rice pounded in honey. The worthy fellow, making the best of every thing, took one of the heartiest luncheons he ever ate in his life, and gave his new adorers an exalted idea of how the gods tuck away their food upon grand occasions.

When evening came, the sorcerers of the island took him respectfully by the hand, and conducted him to a sort of house surrounded with talismans; but, as he was entering it, Joe cast an uneasy look at the heaps of human bones that lay scattered around this sanctuary. But he had still more time to think about them when he found himself at last shut up in the cabin.

During the evening and through a part of the night, he heard festive chantings, the reverberations of a kind of drum, and a clatter of old iron, which were very sweet, no doubt, to African ears. Then there were howling choruses, accompanied by endless dances by gangs of natives who circled round and round the sacred hut with contortions and grimaces.

Joe could catch the sound of this deafening orchestra, through the mud and reeds of which his cabin was built; and perhaps under other circumstances he might have been amused by these strange ceremonies; but his mind was soon disturbed by quite different and less agreeable reflections. Even looking at the bright side of things, he found it both stupid and sad to be left alone in the midst of this savage country and among these wild tribes. Few travellers who had penetrated to these regions had ever again seen their native land. Moreover, could he trust to the worship of which he saw himself the object? He had good reason to believe in the vanity of human greatness; and he asked himself whether, in this country, adoration did not sometimes go to the length of eating the object adored!

But, notwithstanding this rather perplexing prospect, after some hours of meditation, fatigue got the better of his gloomy thoughts, and Joe fell into a profound slumber, which would have lasted no doubt until sunrise, had not a very unexpected sensation of dampness awakened the sleeper. Ere long this dampness became water, and that water gained so rapidly that it had soon mounted to Joe’s waist.

“What can this be?” said he; “a flood! a water-spout! or a new torture invented by these blacks? Faith, though, I’m not going to wait here till it’s up to my neck!”

And, so saying, he burst through the frail wall with a jog of his powerful shoulder, and found himself—where?—in the open lake! Island there was none. It had sunk during the night. In its place, the watery immensity of Lake Tchad!

“A poor country for the land-owners!” said Joe, once more vigorously resorting to his skill in the art of natation.

One of those phenomena, which are by no means unusual on Lake Tchad, had liberated our brave Joe. More than one island, that previously seemed to have the solidity of rock, has been submerged in this way; and the people living along the shores of the mainland have had to pick up the unfortunate survivors of these terrible catastrophes.

Joe knew nothing about this peculiarity of the region, but he was none the less ready to profit by it. He caught sight of a boat drifting about, without occupants, and was soon aboard of it. He found it to be but the trunk of a tree rudely hollowed out; but there were a couple of paddles in it, and Joe, availing himself of a rapid current, allowed his craft to float along.

“But let us see where we are,” he said. “The polar-star there, that does its work honorably in pointing out the direction due north to everybody else, will, most likely, do me that service.”

He discovered, with satisfaction, that the current was taking him toward the northern shore of the lake, and he allowed himself to glide with it. About two o’clock in the morning he disembarked upon a promontory covered with prickly reeds, that proved very provoking and inconvenient even to a philosopher like him; but a tree grew there expressly to offer him a bed among its branches, and Joe climbed up into it for greater security, and there, without sleeping much, however, awaited the dawn of day.

When morning had come with that suddenness which is peculiar to the equatorial regions, Joe cast a glance at the tree which had sheltered him during the last few hours, and beheld a sight that chilled the marrow in his bones. The branches of the tree were literally covered with snakes and chameleons! The foliage actually was hidden beneath their coils, so that the beholder might have fancied that he saw before him a new kind of tree that bore reptiles for its leaves and fruit. And all this horrible living mass writhed and twisted in the first rays of the morning sun! Joe experienced a keen sensation or terror mingled with disgust, as he looked at it, and he leaped precipitately from the tree amid the hissings of these new and unwelcome bedfellows.

“Now, there’s something that I would never have believed!” said he.

He was not aware that Dr. Vogel’s last letters had made known this singular feature of the shores of Lake Tchad, where reptiles are more numerous than in any other part of the world. But after what he had just seen, Joe determined to be more circumspect for the future; and, taking his bearings by the sun, he set off afoot toward the northeast, avoiding with the utmost care cabins, huts, hovels, and dens of every description, that might serve in any manner as a shelter for human beings.

How often his gaze was turned upward to the sky! He hoped to catch a glimpse, each time, of the _Victoria;_ and, although he looked vainly during all that long, fatiguing day of sore foot-travel, his confident reliance on his master remained undiminished. Great energy of character was needed to enable him thus to sustain the situation with philosophy. Hunger conspired with fatigue to crush him, for a man’s system is not greatly restored and fortified by a diet of roots, the pith of plants, such as the _mélé_, or the fruit of the _doum_ palm-tree; and yet, according to his own calculations, Joe was enabled to push on about twenty miles to the westward.

His body bore in scores of places the marks of the thorns with which the lake-reeds, the acacias, the mimosas, and other wild shrubbery through which he had to force his way, are thickly studded; and his torn and bleeding feet rendered walking both painful and difficult. But at length he managed to react against all these sufferings; and when evening came again, he resolved to pass the night on the shores of Lake Tchad.

There he had to endure the bites of myriads of insects—gnats, mosquitoes, ants half an inch long, literally covered the ground; and, in less than two hours, Joe had not a rag remaining of the garments that had covered him, the insects having devoured them! It was a terrible night, that did not yield our exhausted traveller an hour of sleep. During all this time the wild-boars and native buffaloes, reënforced by the _ajoub_—a very dangerous species of _lamantine_—carried on their ferocious revels in the bushes and under the waters of the lake, filling the night with a hideous concert. Joe dared scarcely breathe. Even his courage and coolness had hard work to bear up against so terrible a situation.

At length, day came again, and Joe sprang to his feet precipitately; but judge of the loathing he felt when he saw what species of creature had shared his couch—a toad!—but a toad five inches in length, a monstrous, repulsive specimen of vermin that sat there staring at him with huge round eyes. Joe felt his stomach revolt at the sight, and, regaining a little strength from the intensity of his repugnance, he rushed at the top of his speed and plunged into the lake. This sudden bath somewhat allayed the pangs of the itching that tortured his whole body; and, chewing a few leaves, he set forth resolutely, again feeling an obstinate resolution in the act, for which he could hardly account even to his own mind. He no longer seemed to have entire control of his own acts, and, nevertheless, he felt within him a strength superior to despair.

However, he began now to suffer terribly from hunger. His stomach, less resigned than he was, rebelled, and he was obliged to fasten a tendril of wild-vine tightly about his waist. Fortunately, he could quench his thirst at any moment, and, in recalling the sufferings he had undergone in the desert, he experienced comparative relief in his exemption from that other distressing want.

“What can have become of the _Victoria?_” he wondered. “The wind blows from the north, and she should be carried back by it toward the lake. No doubt the doctor has gone to work to right her balance, but yesterday would have given him time enough for that, so that may be to-day—but I must act just as if I was never to see him again. After all, if I only get to one of the large towns on the lake, I’ll find myself no worse off than the travellers my master used to talk about. Why shouldn’t I work my way out of the scrape as well as they did? Some of them got back home again. Come, then! the deuce! Cheer up, my boy!”

Thus talking to himself and walking on rapidly, Joe came right upon a horde of natives in the very depths of the forest, but he halted in time and was not seen by them. The negroes were busy poisoning arrows with the juice of the _euphorbium_—a piece of work deemed a great affair among these savage tribes, and carried on with a sort of ceremonial solemnity.

Joe, entirely motionless and even holding his breath, was keeping himself concealed in a thicket, when, happening to raise his eyes, he saw through an opening in the foliage the welcome apparition of the balloon—the _Victoria_ herself—moving toward the lake, at a height of only about one hundred feet above him. But he could not make himself heard; he dared not, could not make his friends even see him!

Tears came to his eyes, not of grief but of thankfulness; his master was then seeking him; his master had not left him to perish! He would have to wait for the departure of the blacks; then he could quit his hiding-place and run toward the borders of Lake Tchad!

But by this time the _Victoria_ was disappearing in the distant sky. Joe still determined to wait for her; she would come back again, undoubtedly. She did, indeed, return, but farther to the eastward. Joe ran, gesticulated, shouted—but all in vain! A strong breeze was sweeping the balloon away with a speed that deprived him of all hope.

For the first time, energy and confidence abandoned the heart of the unfortunate man. He saw that he was lost. He thought his master gone beyond all prospect of return. He dared no longer think; he would no longer reflect!

Like a crazy man, his feet bleeding, his body cut and torn, he walked on during all that day and a part of the next night. He even dragged himself along, sometimes on his knees, sometimes with his hands. He saw the moment nigh when all his strength would fail, and nothing would be left to him but to sink upon the ground and die.

Thus working his way along, he at length found himself close to a marsh, or what he knew would soon become a marsh, for night had set in some hours before, and he fell by a sudden misstep into a thick, clinging mire. In spite of all his efforts, in spite of his desperate struggles, he felt himself sinking gradually in the swampy ooze, and in a few minutes he was buried to his waist.

“Here, then, at last, is death!” he thought, in agony, “and what a death!”

He now began to struggle again, like a madman; but his efforts only served to bury him deeper in the tomb that the poor doomed lad was hollowing for himself; not a log of wood or a branch to buoy him up; not a reed to which he might cling! He felt that all was over! His eyes convulsively closed!

“Master! master!—Help!” were his last words; but his voice, despairing, unaided, half stifled already by the rising mire, died away feebly on the night.

CHAPTER THIRTY-SIXTH.

A Throng of People on the Horizon.—A Troop of Arabs.—The Pursuit.—It is He.—Fall from Horseback.—The Strangled Arab.—A Ball from Kennedy.—Adroit Manœuvres.—Caught up flying.—Joe saved at last.

From the moment when Kennedy resumed his post of observation in the front of the car, he had not ceased to watch the horizon with his utmost attention.

After the lapse of some time he turned toward the doctor and said:

“If I am not greatly mistaken I can see, off yonder in the distance, a throng of men or animals moving. It is impossible to make them out yet, but I observe that they are in violent motion, for they are raising a great cloud of dust.”

“May it not be another contrary breeze?” said the doctor, “another whirlwind coming to drive us back northward again?” and while speaking he stood up to examine the horizon.

“I think not, Samuel; it is a troop of gazelles or of wild oxen.”

“Perhaps so, Dick; but yon throng is some nine or ten miles from us at least, and on my part, even with the glass, I can make nothing of it!”

“At all events I shall not lose sight of it. There is something remarkable about it that excites my curiosity. Sometimes it looks like a body of cavalry manœuvring. Ah! I was not mistaken. It is, indeed, a squadron of horsemen. Look—look there!”

The doctor eyed the group with great attention, and, after a moment’s pause, remarked:

“I believe that you are right. It is a detachment of Arabs or Tibbous, and they are galloping in the same direction with us, as though in flight, but we are going faster than they, and we are rapidly gaining on them. In half an hour we shall be near enough to see them and know what they are.”

Kennedy had again lifted his glass and was attentively scrutinizing them. Meanwhile the crowd of horsemen was becoming more distinctly visible, and a few were seen to detach themselves from the main body.

“It is some hunting manœuvre, evidently,” said Kennedy. “Those fellows seem to be in pursuit of something. I would like to know what they are about.”

“Patience, Dick! In a little while we shall overtake them, if they continue on the same route. We are going at the rate of twenty miles per hour, and no horse can keep up with that.”

Kennedy again raised his glass, and a few minutes later he exclaimed:

“They are Arabs, galloping at the top of their speed; I can make them out distinctly. They are about fifty in number. I can see their _bournouses_ puffed out by the wind. It is some cavalry exercise that they are going through. Their chief is a hundred paces ahead of them and they are rushing after him at headlong speed.”

“Whoever they may be, Dick, they are not to be feared, and then, if necessary, we can go higher.”

“Wait, doctor—wait a little!”

“It’s curious,” said Kennedy again, after a brief pause, “but there’s something going on that I can’t exactly explain. By the efforts they make, and the irregularity of their line, I should fancy that those Arabs are pursuing some one, instead of following.”

“Are you certain of that, Dick?”

“Oh! yes, it’s clear enough now. I am right! It is a pursuit—a hunt—but a man-hunt! That is not their chief riding ahead of them, but a fugitive.”

“A fugitive!” exclaimed the doctor, growing more and more interested.

“Yes!”

“Don’t lose sight of him, and let us wait!”

Three or four miles more were quickly gained upon these horsemen, who nevertheless were dashing onward with incredible speed.

“Doctor! doctor!” shouted Kennedy in an agitated voice.

“What is the matter, Dick?”

“Is it an illusion? Can it be possible?”

“What do you mean?”

“Wait!” and so saying, the Scot wiped the sights of his spy-glass carefully, and looked through it again intently.

“Well?” questioned the doctor.

“It is he, doctor!”

“He!” exclaimed Ferguson with emotion.

“It is he! no other!” and it was needless to pronounce the name.

“Yes! it is he! on horseback, and only a hundred paces in advance of his enemies! He is pursued!”

“It is Joe—Joe himself!” cried the doctor, turning pale.

“He cannot see us in his flight!”

“He will see us, though!” said the doctor, lowering the flame of his blow-pipe.

“But how?”

“In five minutes we shall be within fifty feet of the ground, and in fifteen we shall be right over him!”

“We must let him know it by firing a gun!”

“No! he can’t turn back to come this way. He’s headed off!”

“What shall we do, then?”

“We must wait.”

“Wait?—and these Arabs!”

“We shall overtake them. We’ll pass them. We are not more than two miles from them, and provided that Joe’s horse holds out!”

“Great God!” exclaimed Kennedy, suddenly.

“What is the matter?”

Kennedy had uttered a cry of despair as he saw Joe fling himself to the ground. His horse, evidently exhausted, had just fallen headlong.

“He sees us!” cried the doctor, “and he motions to us, as he gets upon his feet!”

“But the Arabs will overtake him! What is he waiting for? Ah! the brave lad! Huzza!” shouted the sportsman, who could no longer restrain his feelings.

Joe, who had immediately sprung up after his fall, just as one of the swiftest horsemen rushed upon him, bounded like a panther, avoided his assailant by leaping to one side, jumped up behind him on the crupper, seized the Arab by the throat, and, strangling him with his sinewy hands and fingers of steel, flung him on the sand, and continued his headlong flight.

A tremendous howl was heard from the Arabs, but, completely engrossed by the pursuit, they had not taken notice of the balloon, which was now but five hundred paces behind them, and only about thirty feet from the ground. On their part, they were not twenty lengths of their horses from the fugitive.

One of them was very perceptibly gaining on Joe, and was about to pierce him with his lance, when Kennedy, with fixed eye and steady hand, stopped him short with a ball, that hurled him to the earth.

Joe did not even turn his head at the report. Some of the horsemen reined in their barbs, and fell on their faces in the dust as they caught sight of the _Victoria;_ the rest continued their pursuit.

“But what is Joe about?” said Kennedy; “he don’t stop!”

“He’s doing better than that, Dick! I understand him! He’s keeping on in the same direction as the balloon. He relies upon our intelligence. Ah! the noble fellow! We’ll carry him off in the very teeth of those Arab rascals! We are not more than two hundred paces from him!”

“What are we to do?” asked Kennedy.

“Lay aside your rifle, Dick.”

And the Scot obeyed the request at once.

“Do you think that you can hold one hundred and fifty pounds of ballast in your arms?”

“Ay, more than that!”

“No! That will be enough!”

And the doctor proceeded to pile up bags of sand in Kennedy’s arms.

“Hold yourself in readiness in the back part of the car, and be prepared to throw out that ballast at a single effort. But, for your life, don’t do so until I give the word!”

“Be easy on that point.”

“Otherwise, we should miss Joe, and he would be lost.”

“Count upon me!”

The _Victoria_ at that moment almost commanded the troop of horsemen who were still desperately urging their steeds at Joe’s heels. The doctor, standing in the front of the car, held the ladder clear, ready to throw it at any moment. Meanwhile, Joe had still maintained the distance between himself and his pursuers—say about fifty feet. The _Victoria_ was now ahead of the party.

“Attention!” exclaimed the doctor to Kennedy.

“I’m ready!”

“Joe, look out for yourself!” shouted the doctor in his sonorous, ringing voice, as he flung out the ladder, the lowest ratlines of which tossed up the dust of the road.

As the doctor shouted, Joe had turned his head, but without checking his horse. The ladder dropped close to him, and at the instant he grasped it the doctor again shouted to Kennedy:

“Throw ballast!”

“It’s done!”

And the _Victoria_, lightened by a weight greater than Joe’s, shot up one hundred and fifty feet into the air.

Joe clung with all his strength to the ladder during the wide oscillations that it had to describe, and then making an indescribable gesture to the Arabs, and climbing with the agility of a monkey, he sprang up to his companions, who received him with open arms.

The Arabs uttered a scream of astonishment and rage. The fugitive had been snatched from them on the wing, and the _Victoria_ was rapidly speeding far beyond their reach.

“Master! Kennedy!” ejaculated Joe, and overwhelmed, at last, with fatigue and emotion, the poor fellow fainted away, while Kennedy, almost beside himself, kept exclaiming:

“Saved—saved!”

“Saved indeed!” murmured the doctor, who had recovered all his phlegmatic coolness.

Joe was almost naked. His bleeding arms, his body covered with cuts and bruises, told what his sufferings had been. The doctor quietly dressed his wounds, and laid him comfortably under the awning.

Joe soon returned to consciousness, and asked for a glass of brandy, which the doctor did not see fit to refuse, as the faithful fellow had to be indulged.

After he had swallowed the stimulant, Joe grasped the hands of his two friends and announced that he was ready to relate what had happened to him.

But they would not allow him to talk at that time, and he sank back into a profound sleep, of which he seemed to have the greatest possible need.

The _Victoria_ was then taking an oblique line to the westward. Driven by a tempestuous wind, it again approached the borders of the thorny desert, which the travellers descried over the tops of palm-trees, bent and broken by the storm; and, after having made a run of two hundred miles since rescuing Joe, it passed the tenth degree of east longitude about nightfall.

CHAPTER THIRTY-SEVENTH.

The Western Route.—Joe wakes up.—His Obstinacy.—End of Joe’s Narrative.—Tagelei.—Kennedy’s Anxieties.—The Route to the North.—A Night near Aghades.

During the night the wind lulled as though reposing after the boisterousness of the day, and the _Victoria_ remained quietly at the top of the tall sycamore. The doctor and Kennedy kept watch by turns, and Joe availed himself of the chance to sleep most sturdily for twenty-four hours at a stretch.

“That’s the remedy he needs,” said Dr. Ferguson. “Nature will take charge of his care.”

With the dawn the wind sprang up again in quite strong, and moreover capricious gusts. It shifted abruptly from south to north, but finally the _Victoria_ was carried away by it toward the west.

The doctor, map in hand, recognized the kingdom of Damerghou, an undulating region of great fertility, in which the huts that compose the villages are constructed of long reeds interwoven with branches of the _asclepia_. The grain-mills were seen raised in the cultivated fields, upon small scaffoldings or platforms, to keep them out of the reach of the mice and the huge ants of that country.

They soon passed the town of Zinder, recognized by its spacious place of execution, in the centre of which stands the “tree of death.” At its foot the executioner stands waiting, and whoever passes beneath its shadow is immediately hung!

Upon consulting his compass, Kennedy could not refrain from saying:

“Look! we are again moving northward.”

“No matter; if it only takes us to Timbuctoo, we shall not complain. Never was a finer voyage accomplished under better circumstances!”

“Nor in better health,” said Joe, at that instant thrusting his jolly countenance from between the curtains of the awning.

“There he is! there’s our gallant friend—our preserver!” exclaimed Kennedy, cordially.—“How goes it, Joe?”

“Oh! why, naturally enough, Mr. Kennedy, very naturally! I never felt better in my life! Nothing sets a man up like a little pleasure-trip with a bath in Lake Tchad to start on—eh, doctor?”

“Brave fellow!” said Ferguson, pressing Joe’s hand, “what terrible anxiety you caused us!”

“Humph! and you, sir? Do you think that I felt easy in my mind about you, gentlemen? You gave me a fine fright, let me tell you!”

“We shall never agree in the world, Joe, if you take things in that style.”

“I see that his tumble hasn’t changed him a bit,” added Kennedy.

“Your devotion and self-forgetfulness were sublime, my brave lad, and they saved us, for the _Victoria_ was falling into the lake, and, once there, nobody could have extricated her.”

“But, if my devotion, as you are pleased to call my summerset, saved you, did it not save me too, for here we are, all three of us, in first-rate health? Consequently we have nothing to squabble about in the whole affair.”

“Oh! we can never come to a settlement with that youth,” said the sportsman.

“The best way to settle it,” replied Joe, “is to say nothing more about the matter. What’s done is done. Good or bad, we can’t take it back.”

“You obstinate fellow!” said the doctor, laughing; “you can’t refuse, though, to tell us your adventures, at all events.”

“Not if you think it worth while. But, in the first place, I’m going to cook this fat goose to a turn, for I see that Mr. Kennedy has not wasted his time.”

“All right, Joe!”

“Well, let us see then how this African game will sit on a European stomach!”

The goose was soon roasted by the flame of the blow-pipe, and not long afterward was comfortably stowed away. Joe took his own good share, like a man who had eaten nothing for several days. After the tea and the punch, he acquainted his friends with his recent adventures. He spoke with some emotion, even while looking at things with his usual philosophy. The doctor could not refrain from frequently pressing his hand when he saw his worthy servant more considerate of his master’s safety than of his own, and, in relation to the sinking of the island of the Biddiomahs, he explained to him the frequency of this phenomenon upon Lake Tchad.

At length Joe, continuing his recital, arrived at the point where, sinking in the swamp, he had uttered a last cry of despair.

“I thought I was gone,” said he, “and as you came right into my mind, I made a hard fight for it. How, I couldn’t tell you—but I’d made up my mind that I wouldn’t go under without knowing why. Just then, I saw—two or three feet from me—what do you think? the end of a rope that had been fresh cut; so I took leave to make another jerk, and, by hook or by crook, I got to the rope. When I pulled, it didn’t give; so I pulled again and hauled away and there I was on dry ground! At the end of the rope, I found an anchor! Ah, master, I’ve a right to call that the anchor of safety, anyhow, if you have no objection. I knew it again! It was the anchor of the _Victoria!_ You had grounded there! So I followed the direction of the rope and that gave me your direction, and, after trying hard a few times more, I got out of the swamp. I had got my strength back with my spunk, and I walked on part of the night away from the lake, until I got to the edge of a very big wood. There I saw a fenced-in place, where some horses were grazing, without thinking of any harm. Now, there are times when everybody knows how to ride a horse, are there not, doctor? So I didn’t spend much time thinking about it, but jumped right on the back of one of those innocent animals and away we went galloping north as fast as our legs could carry us. I needn’t tell you about the towns that I didn’t see nor the villages that I took good care to go around. No! I crossed the ploughed fields; I leaped the hedges; I scrambled over the fences; I dug my heels into my nag; I thrashed him; I fairly lifted the poor fellow off his feet! At last I got to the end of the tilled land. Good! There was the desert. ‘That suits me!’ said I, ‘for I can see better ahead of me and farther too.’ I was hoping all the time to see the balloon tacking about and waiting for me. But not a bit of it; and so, in about three hours, I go plump, like a fool, into a camp of Arabs! Whew! what a hunt that was! You see, Mr. Kennedy, a hunter don’t know what a real hunt is until he’s been hunted himself! Still I advise him not to try it if he can keep out of it! My horse was so tired, he was ready to drop off his legs; they were close on me; I threw myself to the ground; then I jumped up again behind an Arab! I didn’t mean the fellow any harm, and I hope he has no grudge against me for choking him, but I saw you—and you know the rest. The _Victoria_ came on at my heels, and you caught me up flying, as a circus-rider does a ring. Wasn’t I right in counting on you? Now, doctor, you see how simple all that was! Nothing more natural in the world! I’m ready to begin over again, if it would be of any service to you. And besides, master, as I said a while ago, it’s not worth mentioning.”

“My noble, gallant Joe!” said the doctor, with great feeling. “Heart of gold! we were not astray in trusting to your intelligence and skill.”

“Poh! doctor, one has only just to follow things along as they happen, and he can always work his way out of a scrape! The safest plan, you see, is to take matters as they come.”

While Joe was telling his experience, the balloon had rapidly passed over a long reach of country, and Kennedy soon pointed out on the horizon a collection of structures that looked like a town. The doctor glanced at his map and recognized the place as the large village of Tagelei, in the Damerghou country.

“Here,” said he, “we come upon Dr. Barth’s route. It was at this place that he parted from his companions, Richardson and Overweg; the first was to follow the Zinder route, and the second that of Maradi; and you may remember that, of these three travellers, Barth was the only one who ever returned to Europe.”

“Then,” said Kennedy, following out on the map the direction of the _Victoria_, “we are going due north.”

“Due north, Dick.”

“And don’t that give you a little uneasiness?”

“Why should it?”

“Because that line leads to Tripoli, and over the Great Desert.”

“Oh, we shall not go so far as that, my friend—at least, I hope not.”

“But where do you expect to halt?”

“Come, Dick, don’t you feel some curiosity to see Timbuctoo?”

“Timbuctoo?”

“Certainly,” said Joe; “nobody nowadays can think of making the trip to Africa without going to see Timbuctoo.”

“You will be only the fifth or sixth European who has ever set eyes on that mysterious city.”

“Ho, then, for Timbuctoo!”

“Well, then, let us try to get as far as between the seventeenth and eighteenth degrees of north latitude, and there we will seek a favorable wind to carry us westward.”

“Good!” said the hunter. “But have we still far to go to the northward?”

“One hundred and fifty miles at least.”

“In that case,” said Kennedy, “I’ll turn in and sleep a bit.”

“Sleep, sir; sleep!” urged Joe. “And you, doctor, do the same yourself: you must have need of rest, for I made you keep watch a little out of time.”

The sportsman stretched himself under the awning; but Ferguson, who was not easily conquered by fatigue, remained at his post.

In about three hours the _Victoria_ was crossing with extreme rapidity an expanse of stony country, with ranges of lofty, naked mountains of granitic formation at the base. A few isolated peaks attained the height of even four thousand feet. Giraffes, antelopes, and ostriches were seen running and bounding with marvellous agility in the midst of forests of acacias, mimosas, souahs, and date-trees. After the barrenness of the desert, vegetation was now resuming its empire. This was the country of the Kailouas, who veil their faces with a bandage of cotton, like their dangerous neighbors, the Touaregs.

At ten o’clock in the evening, after a splendid trip of two hundred and fifty miles, the _Victoria_ halted over an important town. The moonlight revealed glimpses of one district half in ruins; and some pinnacles of mosques and minarets shot up here and there, glistening in the silvery rays. The doctor took a stellar observation, and discovered that he was in the latitude of Aghades.

This city, once the seat of an immense trade, was already falling into ruin when Dr. Barth visited it.

The _Victoria_, not being seen in the obscurity of night, descended about two miles above Aghades, in a field of millet. The night was calm, and began to break into dawn about three o’clock A.M.; while a light wind coaxed the balloon westward, and even a little toward the south.

Dr. Ferguson hastened to avail himself of such good fortune, and rapidly ascending resumed his aërial journey amid a long wake of golden morning sunshine.

CHAPTER THIRTY-EIGHTH.

A Rapid Passage.—Prudent Resolves.—Caravans in Sight.—Incessant Rains.—Goa.—The Niger.—Golberry, Geoffroy, and Gray.—Mungo Park.—Laing.—René Caillié.—Clapperton.—John and Richard Lander.

The 17th of May passed tranquilly, without any remarkable incident; the desert gained upon them once more; a moderate wind bore the _Victoria_ toward the southwest, and she never swerved to the right or to the left, but her shadow traced a perfectly straight line on the sand.

Before starting, the doctor had prudently renewed his stock of water, having feared that he should not be able to touch ground in these regions, infested as they are by the Aouelim-Minian Touaregs. The plateau, at an elevation of eighteen hundred feet above the level of the sea, sloped down toward the south. Our travellers, having crossed the Aghades route at Murzouk—a route often pressed by the feet of camels—arrived that evening, in the sixteenth degree of north latitude, and four degrees fifty-five minutes east longitude, after having passed over one hundred and eighty miles of a long and monotonous day’s journey.

During the day Joe dressed the last pieces of game, which had been only hastily prepared, and he served up for supper a mess of snipe, that were greatly relished. The wind continuing good, the doctor resolved to keep on during the night, the moon, still nearly at the full, illumining it with her radiance. The _Victoria_ ascended to a height of five hundred feet, and, during her nocturnal trip of about sixty miles, the gentle slumbers of an infant would not have been disturbed by her motion.

On Sunday morning, the direction of the wind again changed, and it bore to the northwestward. A few crows were seen sweeping through the air, and, off on the horizon, a flock of vultures which, fortunately, however, kept at a distance.

The sight of these birds led Joe to compliment his master on the idea of having two balloons.

“Where would we be,” said he, “with only one balloon? The second balloon is like the life-boat to a ship; in case of wreck we could always take to it and escape.”

“You are right, friend Joe,” said the doctor, “only that my life-boat gives me some uneasiness. It is not so good as the main craft.”

“What do you mean by that, doctor?” asked Kennedy.

“I mean to say that the new _Victoria_ is not so good as the old one. Whether it be that the stuff it is made of is too much worn, or that the heat of the spiral has melted the gutta-percha, I can observe a certain loss of gas. It don’t amount to much thus far, but still it is noticeable. We have a tendency to sink, and, in order to keep our elevation, I am compelled to give greater dilation to the hydrogen.”

“The deuce!” exclaimed Kennedy with concern; “I see no remedy for that.”

“There is none, Dick, and that is why we must hasten our progress, and even avoid night halts.”

“Are we still far from the coast?” asked Joe.

“Which coast, my boy? How are we to know whither chance will carry us? All that I can say is, that Timbuctoo is still about four hundred miles to the westward.

“And how long will it take us to get there?”

“Should the wind not carry us too far out of the way, I hope to reach that city by Tuesday evening.”

“Then,” remarked Joe, pointing to a long file of animals and men winding across the open desert, “we shall arrive there sooner than that caravan.”

Ferguson and Kennedy leaned over and saw an immense cavalcade. There were at least one hundred and fifty camels of the kind that, for twelve _mutkals_ of gold, or about twenty-five dollars, go from Timbuctoo to Tafilet with a load of five hundred pounds upon their backs. Each animal had dangling to its tail a bag to receive its excrement, the only fuel on which the caravans can depend when crossing the desert.

These Touareg camels are of the very best race. They can go from three to seven days without drinking, and for two without eating. Their speed surpasses that of the horse, and they obey with intelligence the voice of the _khabir_, or guide of the caravan. They are known in the country under the name of _mehari_.

Such were the details given by the doctor while his companions continued to gaze upon that multitude of men, women, and children, advancing on foot and with difficulty over a waste of sand half in motion, and scarcely kept in its place by scanty nettles, withered grass, and stunted bushes that grew upon it. The wind obliterated the marks of their feet almost instantly.

Joe inquired how the Arabs managed to guide themselves across the desert, and come to the few wells scattered far between throughout this vast solitude.

“The Arabs,” replied Dr. Ferguson, “are endowed by nature with a wonderful instinct in finding their way. Where a European would be at a loss, they never hesitate for a moment. An insignificant fragment of rock, a pebble, a tuft of grass, a different shade of color in the sand, suffice to guide them with accuracy. During the night they go by the polar star. They never travel more than two miles per hour, and always rest during the noonday heat. You may judge from that how long it takes them to cross Sahara, a desert more than nine hundred miles in breadth.”

But the _Victoria_ had already disappeared from the astonished gaze of the Arabs, who must have envied her rapidity. That evening she passed two degrees twenty minutes east longitude, and during the night left another degree behind her.

On Monday the weather changed completely. Rain began to fall with extreme violence, and not only had the balloon to resist the power of this deluge, but also the increase of weight which it caused by wetting the whole machine, car and all. This continuous shower accounted for the swamps and marshes that formed the sole surface of the country. Vegetation reappeared, however, along with the mimosas, the baobabs, and the tamarind-trees.

Such was the Sonray country, with its villages topped with roofs turned over like Armenian caps. There were few mountains, and only such hills as were enough to form the ravines and pools where the _pintadoes_ and snipes went sailing and diving through. Here and there, an impetuous torrent cut the roads, and had to be crossed by the natives on long vines stretched from tree to tree. The forests gave place to jungles, which alligators, hippopotami, and the rhinoceros, made their haunts.

“It will not be long before we see the Niger,” said the doctor. “The face of the country always changes in the vicinity of large rivers. These moving highways, as they are sometimes correctly called, have first brought vegetation with them, as they will at last bring civilization. Thus, in its course of twenty-five hundred miles, the Niger has scattered along its banks the most important cities of Africa.”

“By-the-way,” put in Joe, “that reminds me of what was said by an admirer of the goodness of Providence, who praised the foresight with which it had generally caused rivers to flow close to large cities!”

At noon the _Victoria_ was passing over a petty town, a mere assemblage of miserable huts, which once was Goa, a great capital.

“It was there,” said the doctor, “that Barth crossed the Niger, on his return from Timbuctoo. This is the river so famous in antiquity, the rival of the Nile, to which pagan superstition ascribed a celestial origin. Like the Nile, it has engaged the attention of geographers in all ages; and like it, also, its exploration has cost the lives of many victims; yes, even more of them than perished on account of the other.”

The Niger flowed broadly between its banks, and its waters rolled southward with some violence of current; but our travellers, borne swiftly by as they were, could scarcely catch a glimpse of its curious outline.

“I wanted to talk to you about this river,” said Dr. Ferguson, “and it is already far from us. Under the names of Dhiouleba, Mayo, Egghirreou, Quorra, and other titles besides, it traverses an immense extent of country, and almost competes in length with the Nile. These appellations signify simply ‘the River,’ according to the dialects of the countries through which it passes.”

“Did Dr. Barth follow this route?” asked Kennedy.

“No, Dick: in quitting Lake Tchad, he passed through the different towns of Bornou, and intersected the Niger at Say, four degrees below Goa; then he penetrated to the bosom of those unexplored countries which the Niger embraces in its elbow; and, after eight months of fresh fatigues, he arrived at Timbuctoo; all of which we may do in about three days with as swift a wind as this.”

“Have the sources of the Niger been discovered?” asked Joe.

“Long since,” replied the doctor. “The exploration of the Niger and its tributaries was the object of several expeditions, the principal of which I shall mention: Between 1749 and 1758, Adamson made a reconnoissance of the river, and visited Gorea; from 1785 to 1788, Golberry and Geoffroy travelled across the deserts of Senegambia, and ascended as far as the country of the Moors, who assassinated Saugnier, Brisson, Adam, Riley, Cochelet, and so many other unfortunate men. Then came the illustrious Mungo Park, the friend of Sir Walter Scott, and, like him, a Scotchman by birth. Sent out in 1795 by the African Society of London, he got as far as Bambarra, saw the Niger, travelled five hundred miles with a slave-merchant, reconnoitred the Gambia River, and returned to England in 1797. He again set out, on the 30th of January, 1805, with his brother-in-law Anderson, Scott, the designer, and a gang of workmen; he reached Gorea, there added a detachment of thirty-five soldiers to his party, and saw the Niger again on the 19th of August. But, by that time, in consequence of fatigue, privations, ill-usage, the inclemencies of the weather, and the unhealthiness of the country, only eleven persons remained alive of the forty Europeans in the party. On the 16th of November, the last letters from Mungo Park reached his wife; and, a year later a trader from that country gave information that, having got as far as Boussa, on the Niger, on the 23d of December, the unfortunate traveller’s boat was upset by the cataracts in that part of the river, and he was murdered by the natives.”

“And his dreadful fate did not check the efforts of others to explore that river?”

“On the contrary, Dick. Since then, there were two objects in view: namely, to recover the lost man’s papers, as well as to pursue the exploration. In 1816, an expedition was organized, in which Major Grey took part. It arrived in Senegal, penetrated to the Fonta-Jallon, visited the Foullah and Mandingo populations, and returned to England without further results. In 1822, Major Laing explored all the western part of Africa near to the British possessions; and he it was who got so far as the sources of the Niger; and, according to his documents, the spring in which that immense river takes its rise is not two feet broad.

“Easy to jump over,” said Joe.

“How’s that? Easy you think, eh?” retorted the doctor. “If we are to believe tradition, whoever attempts to pass that spring, by leaping over it, is immediately swallowed up; and whoever tries to draw water from it, feels himself repulsed by an invisible hand.”

“I suppose a man has a right not to believe a word of that!” persisted Joe.

“Oh, by all means!—Five years later, it was Major Laing’s destiny to force his way across the desert of Sahara, penetrate to Timbuctoo, and perish a few miles above it, by strangling, at the hands of the Ouelad-shiman, who wanted to compel him to turn Mussulman.”

“Still another victim!” said the sportsman.

“It was then that a brave young man, with his own feeble resources, undertook and accomplished the most astonishing of modern journeys—I mean the Frenchman René Caillié, who, after sundry attempts in 1819 and 1824, set out again on the 19th of April, 1827, from Rio Nunez. On the 3d of August he arrived at Timé, so thoroughly exhausted and ill that he could not resume his journey until six months later, in January, 1828. He then joined a caravan, and, protected by his Oriental dress, reached the Niger on the 10th of March, penetrated to the city of Jenné, embarked on the river, and descended it, as far as Timbuctoo, where he arrived on the 30th of April. In 1760, another Frenchman, Imbert by name, and, in 1810, an Englishman, Robert Adams, had seen this curious place; but René Caillié was to be the first European who could bring back any authentic data concerning it. On the 4th of May he quitted this ‘Queen of the desert;’ on the 9th, he surveyed the very spot where Major Laing had been murdered; on the 19th, he arrived at El-Arouan, and left that commercial town to brave a thousand dangers in crossing the vast solitudes comprised between the Soudan and the northern regions of Africa. At length he entered Tangiers, and on the 28th of September sailed for Toulon. In nineteen months, notwithstanding one hundred and eighty days’ sickness, he had traversed Africa from west to north. Ah! had Caillié been born in England, he would have been honored as the most intrepid traveller of modern times, as was the case with Mungo Park. But in France he was not appreciated according to his worth.”

“He was a sturdy fellow!” said Kennedy, “but what became of him?”

“He died at the age of thirty-nine, from the consequences of his long fatigues. They thought they had done enough in decreeing him the prize of the Geographical Society in 1828; the highest honors would have been paid to him in England.

“While he was accomplishing this remarkable journey, an Englishman had conceived a similar enterprise and was trying to push it through with equal courage, if not with equal good fortune. This was Captain Clapperton, the companion of Denham. In 1829 he reentered Africa by the western coast of the Gulf of Benin; he then followed in the track of Mungo Park and of Laing, recovered at Boussa the documents relative to the death of the former, and arrived on the 20th of August at Sackatoo, where he was seized and held as a prisoner, until he expired in the arms of his faithful attendant Richard Lander.”

“And what became of this Lander?” asked Joe, deeply interested.

“He succeeded in regaining the coast and returned to London, bringing with him the captain’s papers, and an exact narrative of his own journey. He then offered his services to the government to complete the reconnoissance of the Niger. He took with him his brother John, the second child of a poor couple in Cornwall, and, together, these men, between 1829 and 1831, redescended the river from Boussa to its mouth, describing it village by village, mile by mile.”

“So both the brothers escaped the common fate?” queried Kennedy.

“Yes, on this expedition, at least; but in 1833 Richard undertook a third trip to the Niger, and perished by a bullet, near the mouth of the river. You see, then, my friends, that the country over which we are now passing has witnessed some noble instances of self-sacrifice which, unfortunately, have only too often had death for their reward.”

CHAPTER THIRTY-NINTH.

The Country in the Elbow of the Niger.—A Fantastic View of the Hombori Mountains.—Kabra.—Timbuctoo.—The Chart of Dr. Barth.—A Decaying City.—Whither Heaven wills.

During this dull Monday, Dr. Ferguson diverted his thoughts by giving his companions a thousand details concerning the country they were crossing. The surface, which was quite flat, offered no impediment to their progress. The doctor’s sole anxiety arose from the obstinate northeast wind which continued to blow furiously, and bore them away from the latitude of Timbuctoo.

The Niger, after running northward as far as that city, sweeps around, like an immense water-jet from some fountain, and falls into the Atlantic in a broad sheaf. In the elbow thus formed the country is of varied character, sometimes luxuriantly fertile, and sometimes extremely bare; fields of maize succeeded by wide spaces covered with broom-corn and uncultivated plains. All kinds of aquatic birds—pelicans, wild-duck, kingfishers, and the rest—were seen in numerous flocks hovering about the borders of the pools and torrents.

From time to time there appeared an encampment of Touaregs, the men sheltered under their leather tents, while their women were busied with the domestic toil outside, milking their camels and smoking their huge-bowled pipes.

By eight o’clock in the evening the _Victoria_ had advanced more than two hundred miles to the westward, and our aëronauts became the spectators of a magnificent scene.

A mass of moonbeams forcing their way through an opening in the clouds, and gliding between the long lines of falling rain, descended in a golden shower on the ridges of the Hombori Mountains. Nothing could be more weird than the appearance of these seemingly basaltic summits; they stood out in fantastic profile against the sombre sky, and the beholder might have fancied them to be the legendary ruins of some vast city of the middle ages, such as the icebergs of the polar seas sometimes mimic them in nights of gloom.

“An admirable landscape for the ‘Mysteries of Udolpho’!” exclaimed the doctor. “Ann Radcliffe could not have depicted yon mountains in a more appalling aspect.”

“Faith!” said Joe, “I wouldn’t like to be strolling alone in the evening through this country of ghosts. Do you see now, master, if it wasn’t so heavy, I’d like to carry that whole landscape home to Scotland! It would do for the borders of Loch Lomond, and tourists would rush there in crowds.”

“Our balloon is hardly large enough to admit of that little experiment—but I think our direction is changing. Bravo!—the elves and fairies of the place are quite obliging. See, they’ve sent us a nice little southeast breeze, that will put us on the right track again.”

In fact, the _Victoria_ was resuming a more northerly route, and on the morning of the 20th she was passing over an inextricable network of channels, torrents, and streams, in fine, the whole complicated tangle of the Niger’s tributaries. Many of these channels, covered with a thick growth of herbage, resembled luxuriant meadow-lands. There the doctor recognized the route followed by the explorer Barth when he launched upon the river to descend to Timbuctoo. Eight hundred fathoms broad at this point, the Niger flowed between banks richly grown with cruciferous plants and tamarind-trees. Herds of agile gazelles were seen skipping about, their curling horns mingling with the tall herbage, within which the alligator, half concealed, lay silently in wait for them with watchful eyes.

Long files of camels and asses laden with merchandise from Jenné were winding in under the noble trees. Ere long, an amphitheatre of low-built houses was discovered at a turn of the river, their roofs and terraces heaped up with hay and straw gathered from the neighboring districts.

“There’s Kabra!” exclaimed the doctor, joyously; “there is the harbor of Timbuctoo, and the city is not five miles from here!”

“Then, sir, you are satisfied?” half queried Joe.

“Delighted, my boy!”

“Very good; then every thing’s for the best!”

In fact, about two o’clock, the Queen of the Desert, mysterious Timbuctoo, which once, like Athens and Rome, had her schools of learned men, and her professorships of philosophy, stretched away before the gaze of our travellers.

Ferguson followed the most minute details upon the chart traced by Barth himself, and was enabled to recognize its perfect accuracy.

The city forms an immense triangle marked out upon a vast plain of white sand, its acute angle directed toward the north and piercing a corner of the desert. In the environs there was almost nothing, hardly even a few grasses, with some dwarf mimosas and stunted bushes.

As for the appearance of Timbuctoo, the reader has but to imagine a collection of billiard-balls and thimbles—such is the bird’s-eye view! The streets, which are quite narrow, are lined with houses only one story in height, built of bricks dried in the sun, and huts of straw and reeds, the former square, the latter conical. Upon the terraces were seen some of the male inhabitants, carelessly lounging at full length in flowing apparel of bright colors, and lance or musket in hand; but no women were visible at that hour of the day.

“Yet they are said to be handsome,” remarked the doctor. “You see the three towers of the three mosques that are the only ones left standing of a great number—the city has indeed fallen from its ancient splendor! At the top of the triangle rises the Mosque of Sankore, with its ranges of galleries resting on arcades of sufficiently pure design. Farther on, and near to the Sane-Gungu quarter, is the Mosque of Sidi-Yahia and some two-story houses. But do not look for either palaces or monuments: the sheik is a mere son of traffic, and his royal palace is a counting-house.”

“It seems to me that I can see half-ruined ramparts,” said Kennedy.

“They were destroyed by the Fouillanes in 1826; the city was one-third larger then, for Timbuctoo, an object generally coveted by all the tribes, since the eleventh century, has belonged in succession to the Touaregs, the Sonrayans, the Morocco men, and the Fouillanes; and this great centre of civilization, where a sage like Ahmed-Baba owned, in the sixteenth century, a library of sixteen hundred manuscripts, is now nothing but a mere half-way house for the trade of Central Africa.”

The city, indeed, seemed abandoned to supreme neglect; it betrayed that indifference which seems epidemic to cities that are passing away. Huge heaps of rubbish encumbered the suburbs, and, with the hill on which the market-place stood, formed the only inequalities of the ground.

When the _Victoria_ passed, there was some slight show of movement; drums were beaten; but the last learned man still lingering in the place had hardly time to notice the new phenomenon, for our travellers, driven onward by the wind of the desert, resumed the winding course of the river, and, ere long, Timbuctoo was nothing more than one of the fleeting reminiscences of their journey.

“And now,” said the doctor, “Heaven may waft us whither it pleases!”

“Provided only that we go westward,” added Kennedy.

“Bah!” said Joe; “I wouldn’t be afraid if it was to go back to Zanzibar by the same road, or to cross the ocean to America.”

“We would first have to be able to do that, Joe!”

“And what’s wanting, doctor?”

“Gas, my boy; the ascending force of the balloon is evidently growing weaker, and we shall need all our management to make it carry us to the sea-coast. I shall even have to throw over some ballast. We are too heavy.”

“That’s what comes of doing nothing, doctor; when a man lies stretched out all day long in his hammock, he gets fat and heavy. It’s a lazybones trip, this of ours, master, and when we get back every body will find us big and stout.”

“Just like Joe,” said Kennedy; “just the ideas for him: but wait a bit! Can you tell what we may have to go through yet? We are still far from the end of our trip. Where do you expect to strike the African coast, doctor?”

“I should find it hard to answer you, Kennedy. We are at the mercy of very variable winds; but I should think myself fortunate were we to strike it between Sierra Leone and Portendick. There is a stretch of country in that quarter where we should meet with friends.”

“And it would be a pleasure to press their hands; but, are we going in the desirable direction?”

“Not any too well, Dick; not any too well! Look at the needle of the compass; we are bearing southward, and ascending the Niger toward its sources.”

“A fine chance to discover them,” said Joe, “if they were not known already. Now, couldn’t we just find others for it, on a pinch?”

“Not exactly, Joe; but don’t be alarmed: I hardly expect to go so far as that.”

At nightfall the doctor threw out the last bags of sand. The _Victoria_ rose higher, and the blow-pipe, although working at full blast, could scarcely keep her up. At that time she was sixty miles to the southward of Timbuctoo, and in the morning the aëronauts awoke over the banks of the Niger, not far from Lake Debo.

CHAPTER FORTIETH.

Dr. Ferguson’s Anxieties.—Persistent Movement southward.—A Cloud of Grasshoppers.—A View of Jenné.—A View of Ségo.—Change of the Wind.—Joe’s Regrets.

The flow of the river was, at that point, divided by large islands into narrow branches, with a very rapid current. Upon one among them stood some shepherds’ huts, but it had become impossible to take an exact observation of them, because the speed of the balloon was constantly increasing. Unfortunately, it turned still more toward the south, and in a few moments crossed Lake Debo.

Dr. Ferguson, forcing the dilation of his aërial craft to the utmost, sought for other currents of air at different heights, but in vain; and he soon gave up the attempt, which was only augmenting the waste of gas by pressing it against the well-worn tissue of the balloon.

He made no remark, but he began to feel very anxious. This persistence of the wind to head him off toward the southern part of Africa was defeating his calculations, and he no longer knew upon whom or upon what to depend. Should he not reach the English or French territories, what was to become of him in the midst of the barbarous tribes that infest the coasts of Guinea? How should he there get to a ship to take him back to England? And the actual direction of the wind was driving him along to the kingdom of Dahomey, among the most savage races, and into the power of a ruler who was in the habit of sacrificing thousands of human victims at his public orgies. There he would be lost!

On the other hand, the balloon was visibly wearing out, and the doctor felt it failing him. However, as the weather was clearing up a little, he hoped that the cessation of the rain would bring about a change in the atmospheric currents.

It was therefore a disagreeable reminder of the actual situation when Joe said aloud:

“There! the rain’s going to pour down harder than ever; and this time it will be the deluge itself, if we’re to judge by yon cloud that’s coming up!”

“What! another cloud?” asked Ferguson.

“Yes, and a famous one,” replied Kennedy.

“I never saw the like of it,” added Joe.

“I breathe freely again!” said the doctor, laying down his spy-glass. “That’s not a cloud!”

“Not a cloud?” queried Joe, with surprise.

“No; it is a swarm.”

“Eh?”

“A swarm of grasshoppers!”

“That? Grasshoppers!”

“Myriads of grasshoppers, that are going to sweep over this country like a water-spout; and woe to it! for, should these insects alight, it will be laid waste.”

“That would be a sight worth beholding!”

“Wait a little, Joe. In ten minutes that cloud will have arrived where we are, and you can then judge by the aid of your own eyes.”

The doctor was right. The cloud, thick, opaque, and several miles in extent, came on with a deafening noise, casting its immense shadow over the fields. It was composed of numberless legions of that species of grasshopper called crickets. About a hundred paces from the balloon, they settled down upon a tract full of foliage and verdure. Fifteen minutes later, the mass resumed its flight, and our travellers could, even at a distance, see the trees and the bushes entirely stripped, and the fields as bare as though they had been swept with the scythe. One would have thought that a sudden winter had just descended upon the earth and struck the region with the most complete sterility.

“Well, Joe, what do you think of that?”

“Well, doctor, it’s very curious, but quite natural. What one grasshopper does on a small scale, thousands do on a grand scale.”

“It’s a terrible shower,” said the hunter; “more so than hail itself in the devastation it ca
