When building a fire, always think about safety first. You don’t want to be that guy who starts a raging wildfire in a national park. If your camping site has a designated fire area, use it. If you’re camping in a more rugged area that lacks fire sites, you’ll need to make your own. Select a site away from trees, bushes, and other plant material. Your fire bed should be on bare earth, not grass (especially dead grass). If you can’t find a bare area, make your own by digging and raking away plant material, taking particular care in clearing away all dry plant material. Dry grass, branches, and bark catch fire easily.
Likewise, London maintains an air of neutrality with his prose, objective and reportorial. He focuses mostly on the narrative and little on the man's interior world and history--indeed, we never even know the man's (or the dog's) name. He is less an individual and more a representative of all humanity, especially humanity up against nature. Also in keeping with the naturalist tradition, the man is obviously not a member of the upper class. Like "the boys," he hopes to strike it rich by prospecting for gold, as did many during the Yukon Gold Rush in the late 19th-century, or even by selling logs.
