Part 24

7th.--The day was bright, clear, pleasant, with a temperature of 45°; and we breakfasted at sunrise, the birds singing in the trees as merrily as if we were in the midst of summer. On the upper edge of the hills on the opposite side of the creek, the black volcanic rock appears; and ascending these, the road passed through a basin, around which the hills swept in such a manner as to give it the appearance of an old crater. Here were strata and broken beds of black scoriated rock, and hills composed of the same, on the summit of one of which there was an opening resembling a rent. We traveled to-day through a country resembling that of yesterday, where, although the surface was hilly, the road was good, being firm, and entirely free from rocks and artemisia. To our left, below, was the great sage plain; and on the right were the near mountains, which presented a smoothly-broken character, or rather a surface waved into numberless hills. The road was occasionally enlivened by meeting Indians, and the day was extremely beautiful and pleasant; and we were pleased to be free from the sage, even for a day. When we had traveled about eight miles, we were nearly opposite to the highest portion of the mountains on the left side of the Smoke River valley; and, continuing on a few miles beyond, we came suddenly in sight of the broad green line of the valley of the _Rivière Boisée_, (wooded river,) black near the gorge where it debouches into the plains, with high precipices of basalt, between walls of which it passes, on emerging from the mountains. Following with the eye its upward course, it appears to be shut in among lofty mountains, confining its valley in a very rugged country.

Descending the hills, after traveling a few miles along the high plain, the road brought us down upon the bottoms of the river, which is a beautiful, rapid stream, with clear mountain water; and, as the name indicates, well wooded with some varieties of timber--among which are handsome cottonwoods. Such a stream had become quite a novelty in this country, and we were delighted this afternoon to make a pleasant camp under fine old trees again. There were several Indian encampments scattered along the river; and a number of their inhabitants, in the course of the evening, came to the camp on horseback with dried and fresh fish, to trade. The evening was clear, and the temperature at sunset 57°.

At the time of the first occupation of this region by parties engaged in the fur-trade, a small party of men, under the command of ----- Reid, constituting all the garrison of a small fort on this river, were surprised and massacred by the Indians; and to this event the stream owes its occasional name of _Reid's river_. On the 8th we traveled about 26 miles, the ridge on the right having scattered pines on the upper parts; and, continuing the next day our road along the river bottom, after a day's travel of 24 miles, we encamped in the evening on the right bank of the river, a mile above the mouth, and early the next morning arrived at Fort _Boise_. This is a simple dwelling-house on the right bank of Snake river, about a mile below the mouth of Rivière Boisée; and on our arrival we were received with an agreeable hospitality by Mr. Payette, an officer of the Hudson's Bay Company, in charge of the fort, all of whose garrison consisted in a Canadian _engagé_.

Here the road recrosses the river, which is broad and deep; but, with our good boat, aided by two canoes, which were found at the place, the camp was very soon transferred to the left bank. Here we found ourselves again surrounded by the sage; artemisia tridentata, and the different shrubs which during our voyage had always made their appearance abundantly on saline soils, being here the prevailing and almost the only plants. Among them the surface was covered with the usual saline efflorescences, which here consist almost entirely of carbonate of soda, with a small portion of chloride of sodium. Mr. Payette had made but slight attempts at cultivation, his efforts being limited to raising a few vegetables, in which he succeeded tolerably well; the post being principally supported by salmon. He was very hospitable and kind to us, and we made a sensible impression upon all his comestibles; but our principal inroad was into the dairy, which was abundantly supplied, stock appearing to thrive extremely well; and we had an unusual luxury in a present of fresh butter, which was, however, by no means equal to that of Fort Hall--probably from some accidental cause. During the day we remained here, there were considerable numbers of miserable, half-naked Indians around the fort, who had arrived from the neighboring mountains. During the summer, the only subsistence of these people is derived from the salmon, of which they are not provident enough to lay up a sufficient store for the winter, during which many of them die from absolute starvation.

Many little accounts and scattered histories, together with an acquaintance which I gradually acquired of their modes of life, had left the aboriginal inhabitants of this vast region pictured in my mind as a race of people whose great and constant occupation was the means of procuring a subsistence; and though want of space and other reasons will prevent me from detailing the many incidents which made this familiar to me, this great feature among the characteristics of the country will gradually be forced upon your mind.

Pointing to the group of Indians who had just arrived from the mountains on the left side of the valley, and who were regarding our usual appliances of civilization with an air of bewildered curiosity, Mr. Payette informed me that, every year since his arrival at this post, he had unsuccessfully endeavored to induce these people to lay up a store of salmon for their winter provision. While the summer weather and the salmon lasted, they lived contentedly and happily, scattered along the different streams where fish are to be found; and as soon as the winter snows began to, fall, little smokes would be seen rising among the mountains, where they would be found in miserable groups, starving out the winter; and sometimes, according to the general belief, reduced to the horror of cannibalism--the strong, of course, preying on the weak. Certain it is they are driven to any extremity for food, and eat every insect, and every creeping thing, however loathsome and repulsive. Snails, lizards, ants--all are devoured with the readiness and greediness of mere animals.

In common with all the other Indians we had encountered since reaching the Pacific waters, these people use the Shoshonee or Snake language, which you will have occasion to remark, in the course of the narrative, is the universal language over a very extensive region.

On the evening of the 10th, I obtained, with the usual observations, a very excellent emersion of the first satellite, agreeing very nearly with the chronometer. From these observations, the longitude of the fort is 116° 47' 00", latitude 43° 49' 22", and elevation above the sea 2,100 feet.

Sitting by the fire on the river bank, and waiting for the immersion of the satellite, which did not take place until after midnight, we heard the monotonous song of the Indians, with which they accompany a certain game of which they are very fond. Of the poetry we could not judge, but the music was miserable.

11th.--The morning was clear, with a light breeze from the east, and a temperature at sunrise of 33°. A part of a bullock purchased at the fort, together with the boat, to assist him in crossing, was left here for Mr. Fitzpatrick, and at 11 o'clock we resumed our journey; and directly leaving the river, and crossing the artemisia plain, in several ascents we reached the foot of a ridge, where the road entered a dry sandy hollow, up which it continued to the head; and, crossing a dividing ridge, entered a similar one. We met here two poor emigrants, (Irishmen,) who had lost their horses two days since--probably stolen by the Indians; and were returning to the fort, in hopes to hear something of them there. They had recently had nothing to eat; and I halted to unpack an animal, and gave them meat for their dinner. In this hollow, the artemisia is partially displaced on the hill-sides by grass; and descending it -- miles, about sunset we reached the _Rivière aux Malheurs_, (the unfortunate or unlucky river,)--a considerable stream, with an average breadth of 50 feet, and, at this time, 18 inches' depth of water.

The bottom lands were generally one and a half mile broad, covered principally with long dry grass; and we had difficulty to find sufficient good grass for the camp. With the exception of a bad place of a few hundred yards long, which occurred in rounding a point of hill to reach the ford of the river, the road during the day had been very good.

12th.--The morning was clear and calm, and the thermometer at sunrise 23°. My attention was attracted by a smoke on the right side of the river, a little below the ford, where I found, on the low banks near the water, a considerable number of hot springs, in which the temperature of the water was 193°. The ground, which was too hot for the naked foot, was covered above and below the springs with an incrustation of common salt, very white and good, and fine-grained.

Leading for five miles up a broad dry branch of the Malheurs river, the road entered a sandy hollow, where the surface was rendered firm by the admixture of other rock; being good and level until arriving near the head of the ravine, where it became a little rocky, and we met with a number of sharp ascents over an undulating surface. Crossing here a dividing ridge, it becomes an excellent road of gradual descent down a very marked hollow; in which, after ten miles, willows began to appear in the dry bed of a head of the _Rivière aux Bouleaux_, (Birch river;) and descending seven miles, we found, at its junction with another branch, a little water, not very good or abundant, but sufficient, in case of necessity, for a camp. Crossing Birch river, we continued for about four miles across a point of hill; the country on the left being entirely mountainous, with no level spot to be seen; whence we descended to Snake river--here a fine-looking stream, with a large body of water and a smooth current; although we hear the roar, and see below us the commencement of rapids, where it enters among the hills. It forms here a deep bay, with a low sand island in the midst; and its course among the mountains is agreeably exchanged for the black volcanic rock. The weather during the day had been very bright and extremely hot; but, as usual, so soon as the sun went down, it was necessary to put on overcoats.

I obtained this evening an observation of an emersion of the first satellite, and our observations of the evening place this encampment in latitude 44° 17' 36", and longitude 116° 56' 45", which is the mean of the results from the satellite and chronometer. The elevation above the sea is 1,880 feet. At this encampment, the grass is scanty and poor.

13th.--The morning was bright, with the temperature at sunrise 28°. The horses had strayed off during the night, probably in search of grass; and, after a considerable delay, we had succeeded in finding all but two, when, about nine o'clock, we heard the sound of an Indian song and drum approaching; and shortly after, three Cayuse Indians appeared in sight, bringing with them the two animals. They belonged to a party which had been on a buffalo-hunt in the neighborhood of the Rocky mountains, and were hurrying home in advance. We presented them with some tobacco and other things, with which they appeared well satisfied, and, moderating their pace, traveled in company with us.

We were now about to leave the valley of the great southern branch of the Columbia river, to which the absence of timber, and the scarcity of water, give the appearance of a desert, to enter a mountainous region, where the soil is good, and in which the face of the country is covered with nutritious grasses and dense forest--land embracing many varieties of trees peculiar to the country, and on which the timber exhibits a luxuriance of growth unknown to the eastern part of the continent and to Europe. This mountainous region connects itself in the southward and westward with the elevated country belonging to the Cascade or California range; and, as will be remarked in the course of the narrative, forms the eastern limit of the fertile and timbered lands along the desert and mountainous region included within the Great Basin--a term which I apply to the intermediate region between the Rocky mountains and the next range, containing many lakes, with their own system of rivers and creeks, (of which the Great Salt is the principal,) and which have no connection with the ocean, or the great rivers which flow into it. This Great Basin is yet to be adequately explored. And here, on quitting the banks of a sterile river, to enter on arable mountains, the remark may be made, that, on this western slope of our continent, the usual order or distribution of good and bad soil is often reversed; the river and creek bottoms being often sterile, and darkened with the gloomy and barren artemisia; while the mountain is often fertile, and covered with rich grass, pleasant to the eye, and good for flocks and herds.

Leaving entirely the Snake river, which is said henceforth to pursue its way through canons, amidst rocky and impracticable mountains, where there is no possibility of traveling with animals, we ascended a long and steep hill; and crossing the dividing ridge, came down into the valley of _Burnt_ river, which here looks like a hole among the hills. The average breadth of the stream here is thirty feet; it is well fringed with the usual small timber; and the soil in the bottoms is good, with better grass than we had lately been accustomed to see.

We now traveled through a very mountainous country; the stream running rather in a ravine than a valley, and the road is decidedly bad and dangerous for single wagons, frequently crossing the stream where the water is sometimes deep; and all the day the animals were fatigued in climbing up and descending a succession of steep ascents, to avoid the precipitous hill-sides; and the common trail, which leads along the mountain-side at places where the river strikes the base, is sometimes bad even for a horseman. The mountains along this day's journey were composed, near the river, of a slaty calcareous rock in a metamorphic condition. It appears originally to have been a slaty sedimentary limestone, but its present condition indicates that it has been altered, and has become partially crystalline--probably from the proximity of volcanic rocks. But though traveling was slow and fatiguing to the animals, we were delighted with the appearance of the country, which was green and refreshing after our tedious journey down the parched valley of Snake river. The mountains were covered with good bunch-grass, (_festuca_;) the water of the streams was cold and pure; their bottoms were handsomely wooded with various kinds of trees; and huge and lofty picturesque precipices where the river cut through the mountain.

We found in the evening some good grass and rushes; and encamped among large timber, principally birch, which had been recently burnt, and blackened, and almost destroyed by fire. The night was calm and tolerably clear, with the thermometer at sunset at 59°. Our journey to-day was about twenty miles.

14th.--The day was clear and calm, with a temperature at sunrise of 46°. After traveling about three miles up the valley, we found the river shut up by precipices in a kind of canon, and the road makes a circuit over the mountains. In the afternoon we reached the river again, by another little ravine; and, after traveling along it for a few miles, left it enclosed among rude mountains; and, ascending a smaller branch; encamped on it about five o'clock, very much elevated above the valley. The view was everywhere limited by mountains, on which were no longer seen the black and barren rocks, but a fertile soil, with excellent grass, and partly well covered with pine. I have never seen a wagon-road equally bad in the same space, as this of yesterday and to-day. I noticed where one wagon had been overturned twice, in a very short distance; and it was surprising to me that those wagons which were in the rear, and could not have had much assistance, got through at all. Still, there is no mud; and the road has one advantage, in being perfectly firm. The day had been warm and very pleasant, and the night was perfectly clear.

15th.--The thermometer at daylight was 42°, and at sunrise 40°; clouds, which were scattered over all the sky, disappeared with the rising sun. The trail did not much improve until we had crossed the dividing-ground between the _Brûlée_ (Burnt) and Powder rivers. The rock displayed on the mountains, as we approached the summit, was a compact trap, decomposed on the exposed surfaces, and apparently an altered argillaceous sandstone, containing small crystalline nodules of anolcime, apparently filling cavities originally existing. From the summit here, the whole horizon shows high mountains; no high plain or level is to be seen; and on the left, from south around by the west to north, the mountains are black with pines; while, through the remaining space to the eastward, they are bald, with the exception of some scattered pines. You will remark that we are now entering a region where all the elevated parts are covered with dense and heavy forests. From the dividing grounds we descended by a mountain road to Powder river, on an old bed of which we encamped. Descending from the summit, we enjoyed a picturesque view of high rocky mountains on the right, illuminated by the setting sun.

From the heights we had looked in vain for a well known landmark on Powder river, which had been described to me by Mr. Payette as _l'arbre seul_, (the lone tree;) and, on arriving at the river, we found a fine tall pine stretched on the ground, which had been felled by some inconsiderate emigrant axe. It had been a beacon on the road for many years past. Our Cayuses had become impatient to reach their homes, and traveled on ahead to day; and this afternoon we were visited by several Indians who belonged to the tribes on the Columbia. They were on horseback, and were out on a hunting excursion, but had obtained no better game than a large gray hare, of which each had some six or seven hanging to his saddle. We were also visited by an Indian who had his lodge and family in the mountain to the left. He was in want of ammunition, and brought with him a beaver-skin to exchange, and which he valued at six charges of powder and ball. I learned from him that there are very few of these animals remaining in this part of the country.

The temperature at sunset was 61°, and the evening clear. I obtained, with other observations, an immersion and emersion of the third satellite. Elevation 3,100 feet.

16th.--For several weeks the weather in the daytime has been very beautiful, clear, and warm; but the nights, in comparison, are very cold. During the night there was ice a quarter of an inch thick in the lodge; and at daylight the thermometer was at 16°, and the same at sunrise, the weather being calm and clear. The annual vegetation now is nearly gone, almost all the plants being out of bloom.

Last night two of our horses had run off again, which delayed us until noon, and we made to-day but a short journey of 13 miles, the road being very good, and encamped in a fine bottom of Powder river.

The thermometer at sunset was at 61°, with an easterly wind, and

## partially clear sky; and the day has been quite pleasant and warm,

though more cloudy than yesterday; and the sun was frequently faint, but it grew finer and clearer towards evening.

17th.--Thermometer at sunrise 25°. The weather at daylight was fine, and the sky without a cloud; but these came up, or were formed by the sun, and at seven were thick over all the sky. Just now, this appears to be the regular course--clear and brilliant during the night, and cloudy during the day. There is snow yet visible in the neighboring mountains, which yesterday extended along our route to the left, in a lofty and dark-blue range, having much the appearance of the Wind River mountains. It is probable that they have received their name of the _Blue mountains_ from the dark-blue appearance given to them by the pines. We traveled this morning across the affluents to Powder river, the road being good, firm, and level, and the country became constantly more pleasant and interesting. The soil appeared to be very deep, and is black and extremely good, as well among the hollows of the hills on the elevated plats, as on the river bottoms, the vegetation being such as is usually found in good ground. The following analytical result shows the precise qualities of this soil, and will justify to science the character of fertility which the eye attributes to it:
