During October many of the dogs died, and it was found that the cause of the trouble was cured whale-meat, several tons of which had to be thrown away. To make good this loss, many musk-oxen were obtained in the Lake Hazen district and along the slopes of the United States Range. At the end of February 1906, Peary started on a sledge-journey with the object of reaching the Pole. In three marches he reached Cape Hecla, where his whole party assembled. From here he advanced over the pack-ice with one main and several supporting parties. Open leads and rough ice made progress slow, and a considerable portion of the track had to be cut with pickaxes. At latitude 84° 38′ a broad lead extending east and west as far as it could be seen completely barred the way. After a delay of six days, Peary’s party managed to cross on young ice which bent beneath their weight. Three days later a gale began to blow, and lasted six days. The ice was broken up, and Peary and Henson were driven 70 miles to the eastward on a large floe. Peary could now receive no aid from his supporting parties, and he decided to make a dash northwards. His party now numbered eight. Everything was abandoned that was not absolutely necessary, and every energy was bent on establishing a record. The character of the ice was now much better than farther south, but cracks and narrow leads increased. By forced marches Peary reached 87° 6′ on 21st April. By this time his sledges were nearly empty, and the ice was still in motion towards the east. He was therefore compelled to start on the return journey. On reaching latitude 84° a lead was encountered over which no crossing could be found, and they were forced to camp on a large floe which drifted steadily eastward. Here some sledges were broken up to cook dog-meat for the party. On the 5th May two Eskimo, sent out as scouts, reported young ice a few miles distant. It was decided to attempt to cross it. The thin ice bent beneath them, but by using snow-shoes the crossing was effected in safety. During the next week the party had to cut their way through a terrible chaos of ice, and on the 12th May they reached the Greenland coast at Cape Neumayer. Here they succeeded in obtaining four hares. Near Cape Neumayer sledge-tracks were found, and as these had no doubt been made by one of the supporting parties, Peary sent two Eskimo to follow the tracks. They returned next day with Clark and his three Eskimo, who were in a terribly famished condition. Fortunately, seven musk-oxen were secured, and for two days the party ate and slept. The remainder of the march back to the _Roosevelt_ was accomplished without any special difficulty. Peary now called in the relief parties who were still out. After a short rest, a trip was made to the west of Grant Land. New land, named “Crocker Land,” was seen to the north-west. On the 30th July, Peary again returned to the _Roosevelt_, which next day started on the return journey.
