   Skookum Bill, full of restless, tireless energy when on the trail, now passed to the other extreme. He slept like a dog, sixteen hours a day, rising to eat and smoke, and then falling back in his bunk, where he coiled himself very much like a hibernating bear. He was stupid with sleep, drugged with it, and he did absolutely nothing, leaving all the work to his partner.
