From here he sent his sledge and ski parties far and wide, west and south and north over an approximate area of a hundred thousand square miles. Long stretches of coast-fine were explored and named, in a few cases unnecessarily, though, strange to say, the unnecessary names were all royal ones, King Oscar Land being the west of Ellesmere Land, Crown Prince Gustav Sea and Prince Gustav Adolf Sea being the Polar Ocean, and King Christian Land being simply Finlay Island. Separated from Finlay Island by Danish Sound and from North Cornwall by Hendriksen Sound, he found two large islands, which—just as John Ross named Boothia after his principal patron, the distiller—Sverdrup named Ellef Ringnes and Amund Ringnes after two of his supporters, the brewers; his other discovery, Axel Heiberg Land—which seems to be Peary's Jesup Land sighted in 1898—to the west and north-west of these, being so called after his other munificent patron. His farthest south was Beechey Island, his farthest west Cape Isachsen in Ellef Ringnes Land, his farthest north Lands Lokk in Grant Land, in latitude 81° 40´ and longitude about 92°, within sixty miles of Aldrich's farthest along the north-eastern coast, the gap afterwards traversed by Peary. Within these limits the amount of coast detail filled in was remarkable. Owing to the favourable condition of the ice and the excellent management in all ways, the sledges frequently did their fifteen miles and more a day. Though the expedition lost its doctor during the first winter, there was little trouble as regards health; and game was in plenty right up to the far north where Hare Fiord tells of hares in hundreds.
