The Canadian Mail sledge, with Buck and the other dogs, arrived in Skaguay. They looked and felt very tired. Buck was very thin. The dogs' feet had cuts on them and they couldn't run. After thirty days without a rest, they were very weak. "Come, my friends," said the driver. "This is the end. Now we'll have a long rest—a very long rest." But there were letters in Skaguay for the men in the North, and the mail sledge had to leave again. The dogs only had a three-day rest. They were tired and weak, and now they couldn't pull the heavy sledge. The men had to buy new, strong dogs, so the Scottish man sold Buck and the other dogs. He didn't ask for a lot of money because the dogs couldn't work very hard. Two American men, Charles and Hal, bought the tired dogs and their harnesses. Charles was forty-five years old and he had weak, watery eyes. Hal was a younger man of about twenty. He wasn't a kind man. He always carried a gun and a big knife with him. The two men looked strange in the North, and they didn't understand life there. Hal and Charles took Buck and the other dogs to their new camp. Buck saw a woman, Mercedes, there, and a very large sledge. Hal put the dogs into their harnesses and the dogs waited. The men put a lot of bags and boxes onto the sledge, and it got heavier and heavier. A man walked past and looked at their sledge. "You have a very big, heavy sledge there," he said to Hal. "It's too heavy. Do you really think it will move?" "Of course—now go away!" shouted Hal, and he took out his club. "Mush! Go! Move!" he shouted to the dogs. The dogs jumped and tried to move the sledge. But it was too heavy and they couldn't move it. "You stupid dogs! You aren't pulling hard!" shouted Hal. "I'll kill you!" And Hal started to hit the weak dogs with his club. Some men came and watched Hal. "Those dogs are tired. They want a rest," said one man. "Be quiet!" shouted Hal, and he started to hit the dogs again. Another man watched angrily. "Those poor dogs," he thought. "That man is very stupid, but I have to help those dogs." So he shouted to Hal, "Break the ice under the sledge. The dogs want to work hard, so don't hit them. Help them, and your sledge will move." Hal didn't want to listen to the man, but his dogs couldn't move. So he broke the ice, and the sledge slowly moved down the street. But the road suddenly, turned left and the large sledge fell over. Bags and boxes went everywhere. Then the harnesses broke from the sledge, and the dogs ran away. Many nice people came and helped Hal, Charles, and Mercedes. They found their things and brought the dogs back. One man said, "You'll have to buy more dogs. Your sledge is very heavy." So Charles bought more dogs, and now they had fourteen animals. They started again, and the men felt happy and important. The heavy sledge moved slowly down the street. The dogs worked as hard as they could. The trip back to Dawson was very bad. Hal, Charles, and Mercedes fought every day. They didn't have any plans and they didn't know about this cold country. They started late in the morning and finished early in the afternoon. So they didn't go many kilometers in a day. They hated the cold, the snow, and the Yukon. They also didn't know about dogs, so they didn't bring much food for them. The dogs began to die because they were tired, weak, and very hungry. In one week, six dogs died, and the other dogs were almost dead. It was beautiful spring weather. The sun came up early and went down late every day. The birds sang, and the trees were green again. The ice on the river started to break. But through these wonderful days, with new life everywhere, the two men, the woman, and
