Now that the sun had made its appearance, Peary decided to start on his white march over the ice cap. On the last day of April three of the party, accompanied by five Eskimos, left Red Cliff House with two sledges and twelve dogs. Three days later Peary followed with one man and a sledge drawn by eight dogs. In a few hours he overtook his friends and proceeded with them as far as Humboldt glacier, where he asked for volunteers for the long trip. All of the men were eager to accompany him, but Astrup was chosen for his companion, and the rest of the party returned to Red Cliff House. Peary and Astrup now began their journey to the northern end of Greenland. They slept during the day and traveled by night, when the glare of the sun was less trying to their eyes. Peary himself went first, leading the way. He was followed by three of his best dogs, harnessed to a light sledge which carried two hundred pounds. These dogs had become so fond of Peary that they tried always to keep as near him as possible. They needed no driving or urging, but followed him into the most dangerous places. In the rear came Astrup, with ten dogs attached to the big sledge which carried the bulk of the luggage. Peary had thought himself on top of the ice cap at Humboldt glacier, but he found that he must climb still higher. As he ascended the weather became colder, and soon snow began to fall. Worse than all, the large sledge broke down, but Peary and Astrup mended it and kept on bravely. At last the weather grew so cold that the snow froze hard, and the two men were able to travel twenty miles a day. For weeks Peary and Astrup marched over the great ice, through snowstorms and furious wind. Whenever fine weather came and the ice became firm and smooth, they dashed along, forgetting the hardships they had endured. At length Peary saw land in the distance. Dark brown and red cliffs, precipices, valleys and mountains, rivers and lakes, lay stretched out before them. The dogs saw land also, and were as delighted as the men. This land looked near, but it was not easy to reach. Men and dogs slipped and scrambled down the ice crest, through slush and water, over sharp rocks, across streams, and through valleys. The sun was very hot, and all the travelers felt the change from the clear cold air of the inland ice to the heat of the coast region. The dogs especially suffered from the heat, and this discomfort, together with their need of fresh meat, made some of them ill. Pau, the leader of the team, seemed very weak, and Peary feared that he would die. Pau was a very brave dog, who had killed many polar bears. He must have had some knowledge of magic; at any rate, he was an expert in slipping his harness. Whenever he wished to, he could slip out and away on a trip of his own in search of food. When the other dogs saw Pau free, they tried to break their harness and follow him, often with success.
