This success caused Kane to make one more effort to reach the hitherto inaccessible Washington Land, and for this purpose he placed all his means at the disposal of one of his seamen, William Morton. A supporting party accompanied Morton to Humboldt Glacier, whence he proceeded with Eskimo Hans Hendrik and a dog-team on the advance journey. Their track lay over the sea-ice, about five miles from, and parallel with, the face of the glacier. Five days took them to the new land to the north, and three days later, June 24, 1854, Morton reached alone an impassable headland, Cape Constitution. From the highest attainable elevation Morton found his view completely cut off to the northeast, but between the west and north he could see the southeastern half of Kennedy's Channel as far north as Mount Ross, 80° 58' N. He says "Not a speck of ice was to be seen as far as I could observe; the sea was open, the swell came from the northward ... and the surf broke in on the rocks below in regular breakers." Morton described accurately the general landscape, but he was an incompetent astronomical observer, and his estimates of distances were excessive. The farthest point was charted nearly a hundred miles north of its true position, while Cape Constitution was placed 31 miles too far north by Morton and 52 geographic miles by Kane, who "corrected" Morton's observations by a series of erroneous bearings. Morton's general account of his explorations has been confirmed by Hans Hendrik in his Memoir written some years since in Eskimo. In the meantime the Etah Eskimo, natives of Prudhoe land, had discovered the brig, and through the interpreter, Hans Hendrik, promptly established friendly relations with Kane. It may be said that the expedition owed its final safety to these natives; their supplies of fresh meat checked scurvy, and later their dog teams rendered retreat possible. Slight misunderstandings, not always the fault of the natives, naturally occurred, but the Eskimo were honest, humane, and willing, and never committed a hostile act.
