A sound disturbed Cameron's reflections. He bent his head listening. A soft wind fanned the paling embers, blew sparks and white ashes and thin smoke away into the enshrouding circle of blackness. His burro did not appear to be moving about. The quiet split to the cry of a coyote. It rose strange, wild, mournful—not the howl of a prowling upland beast baying the campfire or barking at a lonely prospector, but the wail of a wolf, full-voiced, crying out the meaning of the desert and the night. Hunger throbbed in it—hunger for a mate, for offspring, for life. When it ceased, the terrible desert silence smote Cameron, and the cry echoed in his soul. He and that wandering wolf were brothers.
