and the Roman Catholic dioceses of Raphoe, Clogher and Derry. The county returned twelve members to the Irish parliament; after the Union it returned two; but it is now divided into north, east, south and west divisions, each returning one member.
History and Antiquities.—The greater part of Donegal was anciently called Tyrconnell (q.v.) or the country of Conall; and it was sometimes called O’Donnell’s country, after the head chieftains of the district. This district was formed into the county of Donegal in the reign of Queen Elizabeth, in 1585, by the lord-deputy Sir John Perrott. The most noteworthy architectural remains of antiquity in the county are to be found at the head of Lough Swilly, where, situated on the summit of a hill 802 ft. high, some remarkable remains exist of a fortress or palace of the northern Irish kings. These are known as the Grianan of Aileach, and evidently date from a period prior to the 12th century. On Tory Island there are one of the best specimens of a round tower and some other interesting remains. Numerous ruins of ancient castles along the coast prove that much attention was formerly paid to the defence of the country from invasion. The principal are—Kilbarron Castle, an ancient stronghold of the O’Clerys, near Ballyshannon; Donegal Castle, built by the O’Donnells, anciently their chief residence, and now a fine ruin standing close to the water’s edge; Burt Castle, built in the reign of Henry VIII. on the shores of Lough Swilly by Sir Cahir O’Dogherty, to whom is also attributed the erection of Green Castle, one of the strongholds of the clan on Lough Foyle. Near the Castle of Doe, or M‘Swiney’s Castle, at Horn Head, is a natural perforation in the roof of a cave, called M‘Swiney’s Gun, formed by the workings of the ocean into the overhanging cliff. When the wind blows due north, and the tide is at half flood, the gun is seen to spout up jets of water to a height of 100 ft., attended with explosions heard occasionally in favourable weather at an immense distance. Gulmore Fort, on the coast of Lough Swilly, supposed to have been erected by the O’Doghertys, having come into the possession of the crown, was granted in 1609 to the corporation of London. It was afterwards enlarged or rebuilt, and acted a prominent part in the celebrated siege of Derry. Traces of religious houses, some existing only in traditionary or documental records, are also numerous. The ruins of that of Donegal, founded in 1474, afford proofs of its ancient grandeur. At Raphoe, 5 m. N.W. of Lifford, is the cathedral of a former diocese united to that of Derry in 1835.
DONEGAL, a small seaport and market town of Co. Donegal, Ireland (not, as its name would suggest, the county town, which is Lifford), in the south parliamentary division, at the head of Donegal Bay, and the mouth of the river Eask, on the Donegal railway. Pop. (1901) 1214. Its trade in agricultural produce is hampered by the unsatisfactory condition of its harbour, the approach to which is beset with shoals. Here are the ruins of a fine Jacobean castle, occupying the site of a fortress of the O’Donnells of Tyrconnell, but built by Sir Basil Brooke in 1610. There are also considerable remains of a Franciscan monastery, founded in 1474 by one of the O’Donnells, and here were compiled the famous “Annals of the Four Masters,” a record of Irish history completed in 1636 by one Michael O’Clery and his coadjutors. There is a chalybeate well near the town, and 712 m. S., at Ballintra, a small stream forms a series of limestone caverns known as the Pullins. Donegal received a charter from James I., and returned two members to the Irish parliament. The name is said to signify the “fortress of the foreigners,” and to allude to a settlement by the Northmen.
DONELSON, FORT, an entrenched camp at Dover, Tennessee, U.S.A., erected by the Confederates in the Civil War to guard the lower Cumberland river, and taken by the Federals on the 16th of February 1862. It consisted of two continuous lines of entrenchments on the land side, and water batteries commanding the river. After the capture (Feb. 6) of Fort Henry on the lower Tennessee the Union army (three divisions) under Brigadier-General U. S. Grant marched overland to invest Donelson, and the gunboat flotilla (Commodore A. H. Foote) descended the Tennessee and ascended the Cumberland to meet him. Albert Sidney Johnston, the Confederate commander in Kentucky, had thrown a large garrison under General Floyd into Donelson, and Grant was at first outnumbered; though continually reinforced, the latter had at no time more than three men to the Confederates’ two. The troops of both sides were untrained but eager.
On the 12th and 13th of February 1862 the Union divisions, skirmishing heavily, took up their positions investing the fort, and on the 14th Foote’s gunboats attacked the water batteries. The latter received a severe repulse, Foote himself being amongst the wounded, and soon afterwards the Confederates determined to cut their way through Grant’s lines. On the 15th General Pillow attacked the Federal division of McClernand and drove it off the Nashville road; having done this, however, he halted, and even retired. Grant ordered General C. F. Smith’s division to assault a part of the lines which had been denuded of its defenders in order to reinforce Pillow. Smith personally led his young volunteers in the charge and carried all before him. The Confederates returning from the sortie were quite unable to shake his hold on the captured works, and, Grant having reinforced McClernand with Lew Wallace’s division, these two generals reoccupied the lost position on the Nashville road. On the 16th, the two senior Confederate generals Floyd and Pillow having escaped by steamer, the infantry left in the fort under General S. B. Buckner surrendered unconditionally. The Confederate cavalry under Colonel Forrest made its escape by road. The prisoners numbered about 15,000 out of an original total of 18,000.
DONGA, a Bantu word for a ravine, narrow watercourse or gully formed by the action of water. Adopted by the European residents of South Africa from the Kaffirs, the use of the word has been extended by English writers to ravines or watercourses of the nature indicated in various other parts of the world. It is almost equivalent to the Arabic khor, which, however, also means the dry bed of a stream, or a stream flowing through a ravine. The Indian word nullah (properly a watercourse) has also the same significance. The three words are often used interchangeably by English writers.
DONGOLA, a mudiria (province) of the Anglo-Egyptian Sudan. It lies wholly within the region known as Nubia and extends along both banks of the Nile from about 18° N. to 20° N. The rainfall is very slight, and the area of fertility is mainly confined to the lands watered by the Nile. Beyond stretches eastward the Nubian desert, westward the Libyan desert. The Wadi el Kab (Gab), west of and parallel to the Nile, contains, however, a good deal of arable land. This wadi, which is some 63 m. long, obtains water by percolation from the Nile. Farther west is the extensive plateau of Jebel Abiad, and beyond, some 250 m. due west of Debba, is Bir Natron, or Bir Sultan, a valley whence natron is obtained. In this desert region is found the addax, the rarest of Sudan antelopes. The chief grain crops are durra and barley, and date palms are extensively cultivated. The province is also noted for a breed of strong, hardy horses. The largest town is Dongola, but the administrative headquarters of the mudiria are at New Merawi (Merowe, Meroe), on the left bank of the Nile, below the 4th cataract. Other towns, also on the Nile, are Debba and Korti, whence start caravan routes to Kordofan and Omdurman. At Jebel Barkal, in the neighbourhood of Merawi, and elsewhere in the mudiria, are ancient ruins (see Sudan: Anglo-Egyptian). Old Merawi, on the right bank of the Nile, and Sanam Abu Dom, on the left bank, indicate the site of the Ethiopian city of Napata. From Kareima, on the right or northern bank of the Nile, 6 m. above New Merawi, a railway (opened in March 1906) runs to Abu Hamed, whence there is railway connexion with the Red Sea, Khartum and Egypt. From Kareima downstream the Nile is navigable to Kerma, just above the 3rd cataract. Between 1896 and 1904 a railway ran between Kerma and Wadi Halfa. In the last-named year this railway was closed. It had been built for purely military purposes and was unremunerative as a commercial undertaking.
The Dongolese (Dongolawi, Danaglas, Danagalehs) are Nubas in type and language, but have a large admixture of Arab, Turk and other blood. They are great agriculturists and keen
