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,

younger man of about twenty. He wasn't a kind man. He always carried a gun and a

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.

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
