When White Fang is almost five years old, Gray Beaver takes him on a long trip to Fort Yukon. It is 1898, the time of the gold rush. Gray Beaver spends months trading at the fort. White Fang spends his time attacking and killing dogs that arrive on the steamboat that brings prospectors from the south. Some of the local men find it entertaining to watch these fights.
