KERGUELEN See also:ISLAND , KERGUELEN'S See also:LAND, Or DESOLATION ISLAND, an island in the See also:Southern Ocean, to the S.E. of the Cape of See also:Good See also:Hope, and S.W. of See also:Australia, and nearly See also:half-way between them. Kerguelen lies between 48° 39' and 49 44' S. and 68° 42' and 7o° 35' E. Its extreme length is about 85 m., but the See also:area is only about 1400 sq. m. The island is throughout mountainous, presenting from the See also:sea in some directions the See also:appearance of a See also:series of jagged peaks. The various ridges and See also:mountain masses are separated by steep-sided valleys, which run down to the sea, forming deep fjords, so that no See also:part of the interior is more than 12 M. from the sea. The See also:chief summits are Mounts See also:Ross (6120 ft.), See also:Richards (4000), See also:Crozier (3251), Wyville See also:Thomson (316o), See also: Hidden deep mudholes are frequent. Kerguelen Island is of undoubted volcanic origin, the prevailing See also:rock being basaltic lavas, intersected occasionally by dikes, and an active See also:volcano and hot springs are said to exist in the south-west of the island. Judging from the abundant fossil remains of trees, the island must have been thickly clothed with See also:woods and other vegetation of which it has no doubt been denuded by volcanic See also:action and submergence, and possibly by changes of See also:climate. It presents evidences of having been subjected to powerful glaciation, and to subsequent See also:immersion and immense denudation. The soundings made by the " Challenger " and " Gazelle " and the See also:affinities which in certain respects exist between the islands, seem to point to the existence at one See also:time of an extensive land area in this See also:quarter, of which Kerguelen, See also:Prince See also:Edward's Islands, the Crozets, St See also:Paul and See also:Amsterdam are the remains. The Kerguelen See also:plateau rises in many parts to within 1500 fathoms of the See also:surface of the sea. Beds of See also:coal and of red See also:earth are found in some places. The summits of the See also:flat-topped hills about Betsy See also:Cove, in the south-east of the island, are formed of caps of See also:basalt. According to See also:Sir J. D. Hooker the vegetation of Kerguelen Island is of See also:great antiquity; and may have originally reached it from the See also:American See also:continent; it has no affinities with See also:Africa. The See also:present climate is not favourable to permanent vegetation; the island lies within the See also:belt of See also:rain at all seasons of the See also:year, and is reached by no drying winds; its temperature is kept down by the surrounding vast expanse of sea, and it lies within the line of the See also:cold See also:Antarctic See also:drift. The temperature, however, is equable. The mean See also:annual temperature is about 39° F., while the summer temperature has been observed to approach 70°. Tempests and squalls are frequent, and the See also:weather is rarely See also:calm. On the lower slopes of the mountains a See also:rank vegetation exists, which, from the conditions mentioned, is constantly saturated with moisture. A rank grass, Festuca Cookii, grows thickly in places up to 300 ft., with Azorella, Cotula plumosa, &c. Sir J. D. Hooker enumerated twenty-one See also:species of flowering See also:plants, and seven of ferns, lycopods, and Characeae; at least seventy-four species of mosses, twenty-five of Hepaticae, and sixty-one of See also:lichens are known, and there are probably many more. Several of the marine and many species of See also:freshwater See also:algae are See also:peculiar to the island. The characteristic feature of the vegetation, the Kerguelen's Land See also:cabbage, was formerly abundant, but has been greatly reduced by rabbits introduced on to the island. See also:Fur-See also:seals are still found in Kerguelen, though their See also:numbers have been reduced by reckless slaughter. The sea-See also:elephant and sea-See also:leopard are characteristic. Penguins of various kinds are abundant; a See also:teal .(Querquedula Eatoni) peculiar to Kerguelen and the Crozets is also found in consider-able numbers, and petrels, especially the See also:giant See also:petrel (Ossifraga gigantea), skuas, gulls, sheath-bills (Chionis See also:minor), See also:albatross, terns, cormorants and Cape pigeons frequent the island. There is a considerable variety of See also:insects, many of them with remarkable peculiarities of structure, and with a predominance of forms incapable of flying. The island was discovered by the See also:French navigator, Yves See also:Joseph de Kerguelen-Tremarec, a See also:Breton noble (1745-1797), on the 13th of See also:February 1772, and partly surveyed by him in the following year. He was one of those explorers who had been attracted by the belief in a See also:rich southern land, and this island, the South See also:France of his first See also:discovery, was afterwards called by him Desolation Land in his disappointment. See also:Captain See also:Cook visited the island in 1776, and, among other expeditions, the " Challenger " spent some time here, and its See also:staff visited and surveyed various parts of it in See also:January 1874. It was occupied from See also:October 1874 to February 1875 by the expeditions sent from See also:England, See also:Germany, and the See also:United States to observe the transit of See also:Venus. The See also:German South Polar expedition in 1901–19o2 established a meteorological and magnetic station at Royal Sound, under Dr Enzensperger, who died there. In January 1893 Kerguelen was annexed by France, and its commercial exploitation was assigned to a private See also:company. See Y. J. de Kerguelen-Tr6marec, Relation de deux voyages clans See also:les mers australes (See also:Paris, 1782) ; Narratives of the Voyages of Captain Cook and the " Challenger " Expedition; Phil. Trans., vol. 168, containing See also:account of the collections made in Kerguelen by the See also:British transit of Venus expedition in 1874–1875; Lieutard," See also:Mission aux Iles Kerguelen," &c., Annales hydrographiques (Paris, 1893). KERGUELEN'S LAND CABBAGE, in See also:botany, Pringlea antiscorbutica (natural See also:order See also:Cruciferae), a plant resembling in See also:habit, and belonging to the same See also:family as, the See also:common cabbage (Brassica oleracea). The cabbage-like heads of leaves abound ina See also:pale yellow highly pungent essential oil, which gives the plant a peculiar flavour but renders it extremely wholesome. It was discovered by Captain Cook during his first voyage, but the first account of it was published by (Sir) Joseph Hooker in The Botany of the Antarctic Voyage of the "See also:Erebus" and " Terror " in 1839-1843. During the stay of the latter expedition on the island, daily use was made of this See also:vegetable either cooked by itself or boiled with the See also:ship's See also:beef, pork or See also:pea-soup.
