Read the passage from White Fang. At the fall of darkness they swung the dogs into a cluster of spruce trees on the edge of the waterway and made a camp. The coffin, at the side of the fire, served for seat and table. The wolf-dogs, clustered on the far side of the fire, snarled and bickered among themselves, but evinced no inclination to stray off into the darkness.

"Seems to me, Henry, they're stayin' remarkable close to camp," Bill commented.
