His son, GEORGE MERCER DAWSON (1849-1901), was born at Pictou on the 1st of August 1849, and received his education at M'Gill University and the Royal School of Mines, London, where he had a brilliant career. In 1873 he was appointed geologist and naturalist to the North American boundary commission, and two years later he joined the staff of the geological survey of Canada, of which he became assistant director in 1883, and director in 1895. He was in charge of the Canadian government's Yukon expedition in 1887, and his name is permanently written in Dawson City, of gold-bearing fame. As one of the Bering Sea Commissioners he spent the summer of 1891 investigating the facts of the seal fisheries on the northern coasts of Asia and America. For his services there, and at the subsequent arbitration in Paris, he was made a C.M.G. He was elected F.R.S. in 1891, and in the same year was awarded the Bigsby medal by the Geological Society of London. He was president of the Royal Society of Canada in 1893. He died on the 2nd of March 1901. He was the author of many scientific papers and reports, especially on the surface geology and glacial phenomena of the northern and western parts of Canada.
DAWSON CITY, or DAWSON, the capital of the Yukon territory, Canada, on the right bank of the Yukon river, and in the middle of the Klondyke gold region, of which it is the distributing centre. It is situated in beautiful mountainous country, 1400 ft. above the sea, and 1500 m. from the mouth of the Yukon river. It is reached by a fleet of river steamers, and has telegraphic communication. Founded in 1896, its population soon reached over 20,000 at the height of the gold rush; in 1901 it was officially returned as 9142, and is now not more than 5000. The temperature varies from 90° F. in summer to 50° below zero in winter. It possesses three opera-houses and numerous hotels, and is a typical mining town, though even at first there was much less lawlessness than is usually the case in such cities.
DAX, a town of south-western France, capital of an arrondissement in the department of Landes, 92 m. S.S.W, of Bordeaux, on the Southern railway between that city and Bayonne. Pop. (1906) 8585. The town lies on the left bank of the Adour, a stone bridge uniting it to its suburb of Le Sablar on the right bank. It has remains of ancient Gallo-Roman fortifications, now converted into a promenade. The most remarkable building in the town is the church of Notre-Dame, once a cathedral; it was rebuilt from 1656 to 1719, but still preserves a sacristy, a porch and a fine sculptured doorway of the 13th century. The church of St Vincent, to the south-west of the town, derives its name from the first bishop, whose tomb it contains. The church of St Paul-lès-Dax, a suburb on the right bank of the Adour, belongs mainly to the 15th century, and has a Romanesque apse adorned with curious bas-reliefs. On a hill to the west of Dax stands a tower built in memory of the sailor and scientist Jean Charles Borda, born there in 1733; a statue was erected to him in the town in 1891. Dax, which is well known as a winter resort, owes much of its importance to its thermal waters and mud-baths (the deposit of the Adour), which are efficacious in cases of rheumatism, neuralgia and other disorders. The best-known spring is the Fontaine Chaude, which issues into a basin 160 ft. wide in the centre of the town. The principal of numerous bathing establishments are the Grands Thermes, the Bains Salés, adjoining a casino, and the Baignots, which fringe the Adour and are surrounded by gardens. Dax has a sub-prefecture, tribunals of first instance and of commerce, a communal college, a training college and a library. It has salt workings, tanneries, saw-mills, manufactures of soap and corks; commerce is chiefly in the pine wood, resin and cork of the Landes, in mules, cattle, horses and poultry.
