Lieutenant J. B. Lockwood, one of the principal assistants, who had already displayed great skill and energy in sledging, even in prolonged temperature as low as 81° F. below freezing, undertook a long exploring trip up the Greenland coast, to or beyond Cape Britannia. A large party went with him at first, but gradually men were sent back, after establishing supply-depots. “The journey onward was marked by severe storms, rough ice, broken sledges, snow-blindness, minor injuries, and—worst of all for loaded sledges—soft, deep snow.” At last, some distance north of Cape Bryant, all turned back except Lockwood, Sergeant Brainard, and an Eskimo, Christiansen, who, with twenty-five days’ rations, pushed on. In five and one half days they had reached Cape Britannia—the farthest north of the Nares expedition—82° 20´ N. Halting here only long enough to study the landscape from its summit, and make sure of the remarkable fact that this northern end of Greenland is free from the ice-cap, whose northern limit is about lat. 82° N., they rounded a cape, and crossing channel after channel filled with ice, which showed that all this district is an archipelago, reached on May 10th Mary Murray Island, 83° 19´ N. “A violent gale delayed them sixty-three hours, the cold exhausting them physically and the delay mentally. If weather forbade travel, life must be sustained; but they tasted insufficient food only at intervals of fifteen, twenty-four, and nineteen hours—the last as clearing weather made progress possible. Floes so high that the sledge was lowered by dog-traces, ice so broken that the ax cleared the way, and widening water-cracks in increasing numbers impeded progress. But, despite all obstacles, they reached, May 13, 1882, Lockwood Island, 83° 24´ N., 42°, 45´ W., the farthest of their journey, and the highest north [by land], then or now.” They could see land several miles northeast, which they named Cape Washington, the highest known land, and toward the north could overlook a polar sea to within three hundred and fifty miles of the pole. Even here plants were numerous, and foxes, hares, lemmings, and ptarmigans existed. The three heroic travelers returned safely, reaching headquarters on June 3d. Another expedition by Lockwood and his two companions explored and located the west coast of mountainous and glacier-girt Grinnell Land, where the musk-ox and Eskimo hunters range to the northern border. The summer of 1883 brought no relief-ship, and the plan of escape must be put into execution at once. A ship had, in fact, tried to reach Greely in 1882, but, failing, had left supplies of provisions at Cape Sabine and elsewhere. In 1883 another relief expedition sent north was dreadfully mis-managed, and finally the ship itself was lost, and, instead of leaving supplies, took away all that had been stored at Cape Sabine—the precise point where they were to be needed.
