DE HAAS, MAURITZ FREDERICK HENDRICK (1832-1895), American marine painter, was born on the 12th of December 1832 in Rotterdam, Holland. He studied art in the Rotterdam Academy and at The Hague, under Bosboom and Louis Meyer, and in 1851-1852 in London, following the English water-colourists of the day. In 1857 he received an artist’s commission in the Dutch navy, but in 1859, under the patronage of August Belmont, who had recently been minister of the United States at The Hague, he resigned and removed to New York city. He became an associate of the National Academy in 1863 and an academician in 1867, and exhibited annually in the academy, and in 1866 he was one of the founders of the American Society of Painters in Water Colors. He died on the 23rd of November 1895. His “Farragut Passing the Forts at the Battle of New Orleans” and “The Rapids above Niagara,” which were exhibited at the Paris Exposition of 1878, were his best known but not his most typical works, for his favourite subjects were storm and wreck, wind and heavy surf, and less often moonlight on the coasts of Holland, of Jersey, of New England, and of Long Island, and on the English Channel.
His brother, William Frederick de Haas (1830-1880), who emigrated to New York in 1854, was also a marine painter.
DEHRA, a town of British India, headquarters of the Dehra Dun district in the United Provinces. Pop. (1901) 28,095. It lies at an elevation of 2300 ft. Here the Hardwar-Dehra railway terminates. Dehra is the headquarters of the Trigonometrical Survey and of the Forest Department, besides being a cantonment for a Gurkha force. The Forest School, which trains subordinate forest officials for all parts of India, is a fine building. Attached to it is an institution for the scientific study of sylvi-culture and the exploitation and administration of forests. The town of Dehra grew up round the temple built in 1699 by the heretical Sikh Guru, Ram Rai, the founder of the Udasi sect of Ascetics. This temple is a remarkable building in Mahommedan style. The central block, in imitation of the emperor Jahangir’s tomb, contains the bed on which the Guru, after dying at will and coming back to life several times, ultimately died outright; it is an object of great veneration. At the corners of the central block are smaller monuments commemorating the Guru’s wives.
DEHRA DUN, a district of British India, in the Meerut division of the United Provinces. Its area is 1209 sq. m. The district is bounded on the N. by the native state of Tehri or Garhwal, on the E. by British Garhwal, on the S. by the Siwálik hills, which separate it from Saharanpur district, and on the W. by the hill states of Sirmur, Jubbal and Taroch. The valley (the Dun) has an area of about 673 sq. m., and forms a parallelogram 45 m. from N.W. to S.E. and 15 m. broad. It is well wooded, undulating and intersected by streams. On the N.E. the horizon is bounded by the Mussoorie or lower range of the Himalayas, and on the S. by the Siwálik hills. The Himalayas in the north of the district attain a height between 7000 and 8000 ft., one peak reaching an elevation of 8565 ft.; the highest point of the Siwálik range is 3041 ft. above sea-level. The principal passes through the Siwálik hills are the Timli pass, leading to the military station of Chakráta, and the Mohand pass leading to the sanatoriums of Mussoorie and Landaur. The Ganges bounds the Dehra valley on the E.; the Jumna bounds it on the W. From a point about midway between the two rivers, and near the town of Dehra, runs a ridge which forms the watershed of the valley. To the west of this ridge the water collects to form the Asan, a tributary of the Jumna; whilst to the east the Suswa receives the drainage and flows into the Ganges. To the east the valley is characterized by swamps and forests, but to the west the natural depressions freely carry off the surface drainage. Along the central ridge, the water-level lies at a great depth from the surface (228 ft.), but it rises gradually as the country declines towards the great rivers. In 1901 the population was 178,195, showing an increase of 6% in the decade. A railway to Dehra from Hardwar, on the Oudh and Rohilkhand line (32 m.), was completed in 1900. The district is served by the Dun canals. Tea gardens cover a considerable area, and the valley contains a colony of European tea planters.
History.—Dehra Dun only emerges from the mists of legend into authentic history in the 17th century A.D., when it formed part of the Garhwal kingdom. Towards the end of the century the heretical Sikh Guru, Ram Rai, expelled from the Punjab, sought refuge in the Dun and gathered round him a crowd of devotees. Fateh Sah, raja of Garhwal, endowed the temple which he built, round which grew up the town of Gurudwara or Dehra (q.v.). In the 18th century the fertility of the valley attracted the attention of Najib-ud-daula, governor of Saharanpur, who invaded it with an army of Rohillas in 1757 and annexed it to his dominion. His rule, which lasted till 1770, brought great prosperity to the Dun; but on his death it became a prey to the surrounding tribes, its desolation being completed after its conquest by the Gurkhas in 1803. In 1814 it was taken possession of by the British, and in the following year was annexed to Saharanpur. Under British administration the Dun rapidly recovered its prosperity.
