An extensive but imperfectly defined territory lying mostly within the Arctic circle to the NE. of North America, from which it is separated by Davis Strait and Baffin Bay; the area is variously estimated from 512,000 to 320,000 sq. m.; the land lies submerged beneath a vast plain of ice, pierced here and there by mountain tops, but it is conjectured to consist of one large island-continent engirt by groups of smaller islands; only on the S. coast, during the meagre summer, is there any appearance of vegetation; there is a great variety of birds, and the animals include the wolf, fox, bear, reindeer, musk ox, and Arctic hare, while whales, seals, and many kinds of fish are found; the inhabitants are chiefly Esquimaux, but there are some Danish settlements, begun in 1721, and the trade is a Danish monopoly; the country was known in early times to the Scandinavians (of whose settlements there are interesting remains), and was rediscovered by John Davis in 1585.
