DEVIL WORSHIPERS OR YEZEEDEES, an ancient sect of unknown origin, living in the vicinity of Mosul, Asiatic Turkey. This obscure race appears to be a relic of the ancient Chaldeans, but their creed is a compound of Christianity, Chaldean superstitions and Mohammedanism. They believe in one Supreme God respecting whom they preserve great mystery. They also believe in Satan as chief of the angelic host, and that he is to be propitiated both on account of his present power to do harm and his future power to do good. They believe in the existence of seven archangels next in order after Satan, and that Christ was an angelic being in human shape, but that he did not die on the cross. On New Year's Day the Yezeedees hold a festival in propitiation of Satan.

DEVONSHIRE, WILLIAM CAVENDISH, DUKE OF, born April 27, 1808; died in Milnethorpe, Dec. 21, 1891. He was the seventh Duke of Devonshire, succeeding to the title in 1858. Although a member of the House of Commons, and, later by accession to the title, of the House of Lords, he never took a prominent part in politics, devoting himself to business and the manufacture of iron. Possessed of one of the largest estates in England, he was able to carry out large plans, and thereby greatly benefit the industries of the country. The towns of Eastbourne and Barrow-in-Furness are mainly of his building.-His son, LORD FREDERICK CHARLES CAVENDISH, an English statesman, was born at Eastbourne, Sussex, Nov. 30, 1836. He was private secretary to Lord Granville from 1859 to 1864; sat in Parliament for several years; was private secretary to W. E. Gladstone from 1872 to 1873; and financial secretary of the Treasury from 1880 to 1882. Then, as Gladstone's olive branch to Ireland, he was appointed chief secretary to the Lord Lieutenant, but was assassinated, with Under-Secretary Burke, in the Phoenix Park, Dublin, within a few days of his landing, May 6, 1882. His brutal murder excited the indignation of the civilized world, for his qualities had endeared him to many people.

DE WET, CHRISTIAN, a Boer general who figured prominently in the closing months of the Boer War as a leader of a guerrilla band of the Orange Free State burghers. His movements in which enabled him and his band of scouts and raiders to elude capture for several months, and to harass British columns in the attempt to run him and his following to earth. His aptitude for guerrilla warfare and ubiquity in turning up at unexpected places were very tantalizing as well as embarrassing to the British.

Then came his appointment, in the end of 1897,
to the command of the Asiatic squadron, upon
receiving which he remarked that he would be
the first commodore in Asiatic waters since Perry.
For a full account of the events leading up to,
and including, the destruction of the Spanish
fleet, see MANILA, BATTLE OF, in these Supple-
ments. The result of that engagement is best
told in the words of the dispatch he sent to Presì-
dent McKinley: "Manila, May 1.- Squadron
arrived at Manila at daybreak this morning. Im-
mediately engaged, and destroyed the following
Spanish vessels: Reina Christina, Castilla, Don
Antonio de Ulloa, Isla de Luzon, Isla de Cuba,
General Lezo, Marquis del Duero, Cano, Vel-
asco, Isla de Mindanao, a transport and water
battery at Cavité. The squadron is uninjured,
and only a few men are slightly wounded.
This dispatch was received by the President, May
7, and he at once sent his thanks to the Commo-
dore, notifying him, also, that in recognition of
his "splendid achievement" he had been ap-
pointed acting rear-admiral. On May 9, the
President, in a message to Congress, recommended
that the thanks of Congress be awarded to "Acting
Rear-Admiral George Dewey for highly distin-
guished conduct in conflict with the enemy, and
to the officers and men under his command."
A
joint-resolution of thanks was passed, a sword of
honor voted to the Admiral, and medals voted to
commemorate the victory.

Rochester was organized he was made its professor of chemistry and natural philosophy. This place he resigned in 1860, because of failing health, but was able thereafter to give much time to scientific research and to the writing of books, chiefly on botany and zoology. He died on December 5, 1867. W.F.J. DEWEY, GEORGE, American admiral. He was born Dec. 26, 1837, at Montpelier, Vt., being the third son of Julius Gemano Dewey, M.D., who was the 9th in descent from the founder of the family, which, originating in Sandwich, England, settled in Dorchester, Massachusetts, in 1633. In 1852 he went to the Norwich Military Academy, Vermont, where he formed the desire of going to Annapolis, which was realized through Senator Foote's nomination. He entered the academy in 1854, where he became known as the "quiet fellow who could do things," graduating in 1858, fifth in his class, excelling in seamanship. As a midshipman he was sent on a two-year trial cruise, on the Wabash, to the Mediterranean. On the outbreak of the war he was assigned as lieutenant to the Mississippi (Commander Melancthon Smith), which had been Commodore Perry's flagship in the Japan expedition (1852-53). Dewey took a leading part in forcing the passage past Forts Jackson and Phillips, below New Orleans and in sinking the Manassas. He displayed that characteristic coolness and confidence that was to stand him and his country in such good stead in 1898. During the attack on Fort Hudson, March 8-9, 1863, the Mississippi grounded, and he set fire to her and secured the escape of his men. He was made first lieutenant of Farragut's dispatch-boat. He was present at other operations; and at Fort Fisher, on the Agawam, Dec.-Jan., 1864-65, again displayed superior judgment and dedecision.

GEORGE DEWEY.

In March, 1865, he reached the rank of lieutenant-commander, and served two years in European waters, on the Kearsarge and the Colorado. In 1868 he was attached to the Naval Academy; in 1870 received his first command-the Narragansett; in 1872 became commander; and later (1875-1882) acted on the Lighthouse Board. In 1882 he was put in command of the Juanita, of the Asiatic squadron. Promoted to captain in 1884, he was assigned to the Dolphin, the first of the "new navy" known as the "White Squadron"; and in 1885 to the Pensacola, the flagship of the European squadron. In 1889 he was chief of the Bureau of Equipment and Recruiting; and, afterward, again on the Lighthouse Board. On

Theodore Roosevelt, in 1889, said that Dewey "partly grasped and partly made his opportunity"; but added, "it was not a fact that it was an accident that he was sent there in 1897, for he was selected as a man who could go into Manila, if necessary. The victory electrified the world, for its startling suddenness and decisiveness. His country could then well recall the Dewey family motto: "A crown to the conqueror is due."

After the battle Dewey proved equal to dealing with the representatives, at Manila, of the foreign powers; and his subsequent action secured for his country the untithed fruits of victory. The results were far reaching, the most important being the raising the prestige of American arms to the highest point, throughout the world. He was created full admiral, March 2, 1899. On his way home, in the fall of 1899, he received ovations wherever he touched with his unscathed squadron; and after his arrival at New York, Sept. 26, 1899, was given a triumph by the city, which was repeated throughout the country, with honors galore. He was spoken of for the Presidency in 1900, but after contemplating the candidacy, discouraged the idea. He presided at the Schley Court-Martial, 1901, and his disagreement with the majority report was perhaps the most notable incident of that affair. In 1905 he declined the invitation to sit on the International Commission convened at Paris to inquire into the firing upon innocent British trawlers by the Russian squadron on its way down the channel.

The demoralized state of the regency and its army which attacked British territory in 1845, and again in 1848, on both occasions being defeated, impelled the British Ministry to annex the principality under certain conditions, the young Maharajah receiving an annual pension of four lacs of rupees equal to $200,000. The prince later made his residence in England, professed Christianity, and was naturalized, his mother also living in England until her death in 1863. The prince was married twice and had six children by his first wife. Monetary embarrassments and the refusal of the British government to entertain claims for increase of pension, led to theatrical demonstrations of hostility on his part, in which he vainly attempted to gain the assistance of Russia. He afterwards made his peace with the British government and resided in Paris, where he died October 22, 1893.
