Part 21

DREAMS, trains of ideas which present themselves to the mind during sleep. The principal feature of the state of dreaming is the absence of conscious control over the current of thought, so that all kinds of fantastic notions, which in the waking state would at once be put aside, are woven into the texture of the dream. The usual content of dreams consists of aspirations or dreads, which the dreamer had recently entertained or experienced, mixed up with incidents which excited intense emotion at some earlier period of the individual's history, and especially in early childhood. The memory of unpleasant experiences, such, for example, as the horrors of trench warfare, which is repressed in the waking state, tends to force itself on the individual's attention when the conscious control is relaxed in sleep, and to give rise to disturbing dreams which may become so intense as to interfere with sleep and cause insomnia. The only rational remedy for this distressing trouble is to discover the painful incident and persuade the patient frankly to face it and not 'try to forget'. In recent years S. Freud has placed the study of dreams upon a scientific basis. He maintains that dreams represent the fulfilment of wishes. There is usually an utter want of coherency in the images that appear before the mental eye, but this excites no surprise in the dreamer. Occasionally, however, intellectual efforts are made during sleep which would be difficult to surpass in the waking state. It is said that Condillac often brought to a conclusion in his dreams reasonings on which he had been employed during the day; and that Franklin believed that he had been often instructed in his dreams concerning the issue of events which at that time occupied his mind. Coleridge composed from 200 to 300 lines during a dream: the beautiful fragment of _Kubla Khan_, which was all he was able to commit to paper when he awoke, remains a specimen of that dream-poem. Dreams are subjective phenomena dependent on natural causes. They are retrospective and resultant instead of being prospective or prophetic. The latter opinion has, however, prevailed in all ages and among all nations; and hence the common practice of divination or prophesying by dreams, that is, interpreting them as presages of coming events. Some authorities declare that all our dreams take place when we are in process of going to sleep or becoming awake, and that during deep sleep the mind is totally inactive. This is denied by the majority of philosophers, and with apparent reason.--BIBLIOGRAPHY: Havelock Ellis, _The World of Dreams_; S. Freud, _The Interpretation of Dreams_; W. H. R.

DREDGING, a term applied to the operation of removing mud, silt, and other deposits from the bottom of harbours, canals, rivers, docks, &c. The most simple dredging apparatus is the spoon apparatus, which consists of a strong iron ring or hoop, properly formed for making an impression upon the soft matter at the bottom, so as to scoop it into a large leather bag attached to the ring and perforated with a number of small holes. The means for working it is a long handle, a suspending rope, and a crane or sweep-pole planted in a boat. Much more effective is the steam dredging-machine now in common use. It has a succession of strong iron buckets on an endless chain, which travels on a frame whose lower end is vertically adjustable so as to regulate the depth at which it works. It is worked by steam, and the buckets tear up the matter at the bottom, raise it, and discharge it into punts or hoppers close to the dredging vessel. Various forms of steam-pump dredgers, in which suction-pipes are the chief features, are also used. The River Clyde, from being a shallow stream, has been converted, mainly by dredging, into a waterway carrying large vessels up to Glasgow. Dredging rivers for gold is now largely carried on; and the gold-dredge may even be floated in water artificially supplied. The operation of dragging the bottom of the sea for molluscs, plants, and other objects, usually for scientific observation, is also called dredging. The oyster-dredge is a light iron frame with a scraper like a narrow hoe on one side, and a bag attached to receive the oysters. The dredges used by naturalists are mostly modifications of or somewhat similar to the oyster-dredge. Scientific dredging has of late assumed great importance as making us acquainted with the life of deep-sea areas.

DREISENSSIA, a genus of bivalve mollusc allied to the mussels. One species (_D. polymorpha_) is a native of the streams which flow into the Caspian, but has been accidentally introduced into most rivers and estuaries of Europe, including those of Britain, where it is now abundant.

DRELINCOURT (dr[.e]-la[n.]-k[:o]r), Charles, a French Calvinistic minister, born at Sedan 1595, died at Paris 1669. He was the author of many controversial works, and of _Consolations against_ _the fear of Death_. To promote the sale of the English translation of this work, De Foe wrote his _Apparition of Mrs. Veal_.

DRENTHE (dren'te), a province of Holland, bounded by Hanover, Overijssel, Friesland, and Groningen; area, 948 sq. miles. It is in general more elevated than the surrounding provinces, especially in the centre. The soil is generally poor, and the surface largely consists of heath and morass, but the province is famed for its horses and cattle. Drenthe is remarkable for the great number of so-called 'giants' graves' or barrows scattered over the country. Its capital is Assen. Pop. 200,951.

DRES'DEN, the capital of the Republic (former kingdom) of Saxony, is situated in a beautiful valley on both sides of the River Elbe, which is here spanned by four stone bridges and an iron railway bridge. It is first mentioned in history in 1206, and has been the residence of the sovereigns since 1485; was greatly extended and embellished by Augustus the Strong (1694-1736), and rapidly increased during the nineteenth century. Among the chief sights are the museum (joined on to an older range of buildings called the Zwinger), a beautiful building containing a famous picture-gallery and other treasures; the Japanese palace (Augusteum), containing the royal library (founded by the Elector Augustus in the sixteenth century) of 570,000 volumes, besides a rich collection of manuscripts; the Johanneum, containing the collection of porcelain and the historical museum, a valuable collection of arms, armour, and domestic utensils, belonging to the Middle Ages. The palace, built about 1530, restored and remodelled externally between 1890 and 1902, and until 1918 the residence of the kings of Saxony, has also a fine interior, and contains (in what is called the Green Vault) a valuable collection of curiosities, jewels, trinkets, and works of art. The theatre is one of the finest structures of the kind in the world. The city is distinguished for its excellent educational, literary, and artistic institutions, among which are the Technical High School, much on the plan and scale of a university; the Conservatory and School of Music; and the Academy of Fine Arts. The manufactures are not unimportant, and are various in character; the china, however, for which the city is famed, is made chiefly at Meissen, 14 miles distant. The commerce is considerable, and has greatly increased since the development of the railway system. The chief glory of Dresden is the gallery of pictures, one of the finest in the world, which first became of importance under Augustus II, King of Poland and Elector of Saxony, but owes its most valuable treasures to Augustus III, who purchased the greater portion of the gallery of the Duke of Modena for L180,000. The pictures number about 3000, and in particular comprise many fine specimens of the Italian, Dutch, and Flemish schools. Besides this fine collection the museum contains also engravings and drawings amounting to upwards of 350,000. There is also a sculpture-gallery, the Albertinum, where by casts and otherwise the progress of sculpture is exemplified from the earliest times, all the most important antiques being shown. Dresden, being thus rich in treasures of art and favoured by a beautiful natural situation, is the summer resort of many foreigners. It suffered severely in the Thirty Years' War, and also in 1813, when it was the head-quarters of Napoleon's army. It was occupied by the Prussians in 1866, but was evacuated in the following spring. Pop. 548,308.

DRESDEN, BATTLE OF, a battle fought in 1813 (26-27th Aug.), between the French under Napoleon and the Allies under Schwarzenberg. Napoleon had come to the relief of the city, which was occupied by the French. The Allies assaulted and bombarded the city, and soon after a great pitched battle was fought (27th Aug.), the Allies being defeated.

[Illustration: Dresden China. Candelabrum]

DRESDEN CHINA, a delicate, semi-transparent, highly finished china made at Meissen, 14 miles from Dresden. The manufacture resulted from an accidental discovery made by B[:o]ttger, a young chemist, in 1710, and the vases, statuettes, groups of figures, candelabra, and clocks, manufactured during the eighteenth century are highly prized.

DREUX (dr_eu_; DUROCASSIS or DROCAE of the Romans), a French town, department of Eure-et-Loir, on the Blaise, near to where it joins the Eure, 20 miles N.N.W. of Chartres. It is built at the foot of a hill crowned by a dilapidated castle, which contains a chapel, founded in 1142; to which has been added the costly mausoleum of the Orleans family. A battle took place near the town in 1562 between the Royalists under Montmorency and the Huguenots under Cond['e], in which the latter were defeated. Pop. 10,692.

DREYFUS, Alfred, captain of artillery and general staff-officer in the French army, was born of a Jewish family in Mulhouse, Alsace, in 1859. In Oct., 1894, he was arrested on a charge of communicating military documents to a foreign Government, supposed to be Germany; and at a secret court-martial, which sat in December, he was condemned to public degradation and lifelong imprisonment. Early in 1895 he was sent to the [^I]le du Diable (Devil's Island), near Cayenne, to undergo his sentence. About the middle of the same year Colonel Picquart became head of the Intelligence Department, and in the course of his official duties discovered various circumstances tending to throw doubt on the correctness of the court-martial's decision, and pointing to another officer, of the name of Esterhazy, as the real traitor. Picquart was superseded by a Colonel Henry in Nov., 1897, and in the following January Esterhazy, charged by a brother of the condemned man with having written the _bordereau_, or memorandum, which was the chief document relied on by the prosecutors of Dreyfus, was acquitted by a court-martial. Two days later M. Zola, the eminent novelist, in a letter headed _J'accuse_ published in the _Aurore_, made serious charges against the general staff and the Government in connection with the Esterhazy court-martial. He was prosecuted, and condemned to pay a heavy fine and undergo a term of imprisonment. In June, 1898, M. Brisson succeeded M. M['e]line as Prime Minister, and next month M. Cavaignac, his War Minister, read to the Chamber several documents which he regarded as conclusive proof of the guilt of Dreyfus. The chief of these was soon admitted by Colonel Henry to have been forged by him, and M. Cavaignac at once resigned. In June, 1899, the Cour de Cassation ordered a fresh court-martial. The court-martial, which sat at Rennes, found Dreyfus guilty with extenuating circumstances. He was sentenced to ten years' imprisonment, but was pardoned by President Loubet almost immediately. In 1906, when Clemenceau was Prime Minister, the sentence was annulled, and Dreyfus was reinstated in the army (as major). He was shot at by a reactionary journalist in 1908, but escaped without serious injury. In Sept., 1919, Lieutenant-Colonel Dreyfus was publicly presented with the insignia of an officer of the Legion of Honour. Several times during the progress of the case France seemed on the verge of revolution.--Cf. J. Reinach, _Histoire de l'affaire Dreyfus_.

DRIFFIELD, GREAT, a town, England, Yorkshire, at the head of a navigable canal communicating with the Humber at Hull. It lies in a fertile district, has an ancient parish church, and manufactures linseed-cake and manures. Pop. 5676.

DRIFT, in geology, a term applied to earth and rocks which have been conveyed by flood-action, glaciers, or floating ice and deposited over the surface of a country. It is sometimes used in a wider sense to denote all post-Pliocene sands, gravels, and clays, such as the superficial deposits shown on the 'drift' maps of the Geological Survey.

DRIFT, in mining, a horizontal tunnel or passage excavated underground that follows the course of a vein or stratum. Drift, in musketry, is the lateral deviation of the bullet after it has left the barrel of the rifle; it is due to the spin of the bullet and the resistance of the air.

DRIFT SAND, sand thrown up by the waves of the sea, and blown when dry some distance inland until arrested by obstacles, round which it gradually accumulates until the heaps attain considerable dimensions, often forming dunes or sand-hills. Coast-land sometimes requires artificial protection from encroachment by drift-sand.

DRILL, a tool used for boring holes in wood, metal, stone, ivory, &c. It consists of a sharp spindle to which a circular motion is communicated by various contrivances. Drills are of various designs. For rock-boring the diamond rock-drill, an instrument with cutting edges made of bort or black diamond, is now generally adopted. See _Boring_.--Cf. Dana and Saunders, _Rock Drilling_.

DRILL is the A B C of all military movements. In the Training Manuals of the British army the word is defined as "the training of the soldier to perform certain movements as a second nature". It follows, therefore, that drill is an essential part of the training of every soldier, more especially in the early days of his training, in that without it, and without the power of movement in obedience to the expressed will of a superior given by it, a body of soldiers would be merely a collection of armed men who, however willing individually, would be incapable of carrying out collectively an order given for the general good. In the early days of our history, when fighting was largely individual, and the whole duty of a soldier was 'to do unto the other fellow as he would do unto you--and do it first' (with a club), drill, as we know it, was unknown; each man armed himself as he thought fit, and, beyond getting into some formation for the actual purpose of the assault, a battle was largely a go-as-you-please affair. In Saxon days the normal formation for the battle was the wedge; that is two men at the point followed by three, and so on till the available number was used up. This, of course, formed a solid pointed mass with considerable weight, and was used both for attack and defence. But once this formation was broken it was next to impossible to reform it. An instance of this weakness occurred at the battle of Hastings. The English were in this one and only wedge formation, officers and the better armed men at the point, and the less skilful and more indifferently armed at the base. Doubtless the troops had been got into this formation after much exertion in the way of pushing and vituperation, and, once in it, had been told on no account to break it. At a certain stage in the battle the heavily armoured Normans pretended flight; this was too much for the English, who broke their ranks and gave chase, each after his own

## particular source of ransom. This ended the battle; the Normans turned,

and, owing to the entire inability of the English to re-form their ranks, the wedge, and with it the English army, ceased to exist: the result of want of discipline and absence of drill.

Drill and discipline are complementary to each other. In one of the battles of the Peninsular War, the 28th (now the Gloucestershire Regiment) were being hotly attacked in front by a French column. The regiment was firing in two ranks--the front rank kneeling and the rear rank standing--when suddenly a fresh attack developed from the rear. It was a matter of seconds for the commanding officer of the 28th to order the rear rank to turn about; drill and discipline did the rest, and the rear rank turned round, knelt down, and beat off the new attack. Since then the 28th has worn its badges both front and rear of its head-dresses.

Drill is an aid to discipline in that it teaches men that there is a right and a wrong way of doing a thing. Drill and the spirit arising from it has a great steadying effect on the nerves, as when in the European War the Guards Division, after being almost decimated during a German 'push', was brought out of the line and kept to steady drill for a week. To those who did not understand this appeared harsh and futile; to those who did it appeared, as it was, the best means of steadying men tried beyond endurance, and of preparing them for further efforts. Our English drill has passed through many phases in its time; but from the days when large bodies of men performed complicated manoeuvres at the executive command of one man, through the times when drill, perhaps, was considered to be the be-all and end-all of the soldier, to modern days when it is recognized as a means to an end, the guiding principle remains the same, viz. that one of the first essentials for a soldier is that he shall be so trained by drill that he shall know instinctively how to do the right thing at the right time and in the right way. Even now, when drill movements are no longer performed in face of an enemy, accuracy and attention to detail are insisted on in all parade-ground movements as part of the education of the soldier and as an aid to discipline. Drill for the soldier takes the place of the five-finger exercises for the musician. Neither of them, in itself, is of any

## particular value, but each adds to the efficiency of those who practise it.

DRILL (_Papio leucophaeus_), a large variety of baboon, smaller and less fierce than the mandrill, and like it a native of the coast of Guinea. The face and ears are bare and of a glossy black colour, the palms of the hands and soles of the feet are also naked and of a deep copper colour.

DRILLING, the plan of sowing in parallel rows as distinguished from sowing broadcast. It was introduced into England by Jethro Tull, who invented the first implement for drilling, and published a work on the subject in 1731. The crops which are now generally drilled are turnips and flax. The first form of drill was of very simple construction, and was only adapted for potatoes, beans, peas, carrots, clover, cereals, sowing one row at a time, but now a great variety of improved implements is in use, some of which distribute artificial manure with the seed. Among the principal advantages of drilling over broadcast sowing we may mention that a considerable saving of seed is effected in the sowing of grain crops, but the great advantage is that in the case of green crops it enables the farmer more readily to clean the land both by the hand- and by the horse-hoe. To keep the soil stirred and pulverized, which can only be properly done when the crops have been drilled, favours the retention and absorption of the moisture.

[Illustration: Dripstone over window, decorated Gothic, mixed tracery. Two different forms of termination.]

DRIPSTONE, a projecting tablet or moulding over the head of a Gothic doorway, window, archway, or niche to throw off the rain. It is also called a _weather moulding_, and _label_ when it is turned square. It is of various forms; sometimes a head is used as a termination or support, in others an ornament or simple moulding is adopted.

DRIVER, Rev. Samuel Rolles, D.D., professor of Hebrew and Biblical critic, born at Southampton 2nd Oct., 1846, died in 1914. He was educated at Winchester and at New College, Oxford, where he graduated with first-class honours in classics in 1869. In 1866 he gained the Pusey and Ellerton Hebrew Scholarship, and the Kennicott Scholarship (also for Hebrew) four years later, besides prizes for Septuagint Greek and Syriac. He was for some years a fellow and tutor of his college, and from 1876 to 1884 a member of the Old Testament Revision Committee. In 1883, on the death of Dr. Pusey, he became Regius professor of Hebrew at Oxford and (_ipso facto_) a Canon of Christ Church. Of his numerous works we may mention: _A Treatise on the Use of the Tenses in Hebrew_ (1874); _Isaiah: his Life and Times_ (1888); _Introduction to the Literature of the Old Testament_ (1891), a work suited for popular reading, which has passed through many editions; _Sermons on Subjects connected with the Old Testament_ (1892); _The Parallel Psalter_ (1904); _Commentaries_ on various books of the Bible; and articles in _Bible Dictionaries_ and in periodicals. He was a joint editor of the new _Hebrew-English Lexicon of the Old Testament_ published by the Clarendon Press.

DROGHEDA (dro_h_'e-da), an ancient town and seaport, formerly a parliamentary borough, Ireland, in the county of Louth, on both sides of the Boyne, about 4 miles from the sea, 26 miles north of Dublin. The Boyne is here crossed by a railway viaduct of 18 arches and 95 feet high. Flax- and cotton-spinning are carried on; there are also salt-works, breweries, and tanneries; and the fisheries are increasing. There is a good export trade in cattle, sheep, grain, butter, and eggs. In 1412 a Parliament assembled here which enacted Poynings' Law. The town was for a long time strongly fortified, and was taken by Cromwell with great slaughter in 1649; it surrendered to William III immediately after the battle of the Boyne. Pop. 12,500.

DROHOBYCZ (dro'ho-bich), a Polish town in Galicia, formerly belonging to Austria, 41 miles S.S.W. of Lemberg. Its Catholic church is one of the handsomest in the country. It has an important trade, particularly in salt, obtained from springs in the vicinity. Pop. 40,000.

DROIT D'AUBAINE (drw[:a]-d[=o]-b[=a]n), an old rule in some European countries, by which the property of a foreigner who died was claimed by the State, unless the person had a special exemption. In France, where it was not abolished till 1819, the Scots, Savoyards, Swiss, and Portuguese were exempted.

DROITWICH (droit'ich), a town of England, in the county and 6 miles N.N.E. of Worcester, on the Salwarp. It is famous for its brine springs, from which salt has been manufactured for more than 1000 years. Pop. 4146.

DR[^O]ME, a south-east department of France, covered almost throughout by ramifications of the Alps, the average height of which, however, does not exceed 4000 feet; area, 2508 sq. miles, of which about one-fourth is waste, one-third under wood, and a great part of the remainder under tillage and pasture. A considerable extent of the area is occupied by vineyards, and several of the wines produced have a high reputation, especially Hermitage. Olives, chestnuts, and silks are staple productions. Valence is the capital. Pop. 263,509.

DROMEDARY. See _Camel_.

DROMORE', an episcopal city, Ireland, County Down, on the Lagan, here crossed by two bridges, 16 miles south-west of Belfast. Its cathedral contains the tomb of Jeremy Taylor. Pop. 2307.
