May twentieth, Dr. Hays and Godfrey started with the dog team, to make another attempt to cross Smith Strait and reach, along the American side, the unknown north. The doctor was a fresh man, not having been with any previous party. The dogs were rested, well fed, and full of wolfish energy. The second day he fortunately struck into a track free from heavy ice, and made fifty miles! But this success was after the arctic fashion, made to give bitterness to immediate failure. On the third day they encountered hummocks, piled in long ridges across their path; some of them were twenty feet high. Over some of these they climbed, dragging after them both sledge and dogs. Long diversions were made at other times, and their path became in this way so very tortuous that in making ninety miles advance northward they traveled two hundred and seventy miles! Snow-blindness seized Dr. Hays in the midst of these toils. But, nothing daunted, after short halts, in which his sight improved, he pushed on. But Godfrey soon broke down, though one of the hardiest of explorers. Their dogs, too, began to droop; the provisions were running low, and so the homeward track was taken. Before they reached the vessel they were obliged to lighten their load by throwing away fifty pounds weight of furs, the heaviest of which had been used as sleeping bags. This excursion resulted in valuable additions to the extreme northern coast-line survey. On the afternoon of June fourth, M'Gary, with four men, started on a last desperate effort to push the survey, on the Greenland side, a hundred miles farther, by which Dr. Kane thought the limits of the ice in that direction might be reached. Morton, one of the company, was to keep himself as fresh as possible, so that when the rest came to a final halt he might be able to push on farther. Hans was kept at the vessel until the tenth, four days later, when he started light with the dog-sledge to join them. His part was to accompany Morton on the final run.
