Two new men took Buck and his team back north on the long journey to Dawson, travelling with several other dog-teams. It was heavy work; the sledge was loaded with letters for the gold miners of Dawson. Buck did not like it, but he worked hard, and made the other dogs work hard, too. Each day was the same. They started early, before it was light, and at night they stopped and camped and the dogs ate. For the dogs this was the best part of the day, first eating, then resting by the fire.
