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.

Then a sharp clink of metal on stone and soft pads of hoofs in sand prompted Cameron to reach for his gun, and to move out of the light of waning campfire. He was somewhere along the wild border line between Sonora and Arizona; and the prospector who dared the heat and barrenness of that region risked other dangers sometimes as menacing.

Figures darker than the gloom approached and took shape, and in the light turned out to be those of a white man and a heavily packed burro.

“Hello there,” the man called, as he came to a halt and gazed about him. “I saw your fire. May I make camp here?”

Cameron came forth out of the shadow and greeted his visitor, whom he took for a prospector like himself. Cameron resented the breaking of his lonely campfire vigil, but he respected the law of the desert.

The stranger thanked him, and then slipped the pack from his burro. Then he rolled out his pack and began preparations for a meal. His movements were slow and methodical.

Cameron watched him, still with resentment, yet with a curious and growing interest. The campfire burst into a bright blaze, and by its light Cameron saw a man whose gray hair somehow did not seem to make him old, and whose stooped shoulders did not detract from an impression of rugged strength.

“Find any mineral?” asked Cameron, presently.

His visitor looked up quickly, as if startled by the sound of a human voice. He replied, and then the two men talked a little. But the stranger evidently preferred silence. Cameron understood that. He laughed grimly and bent a keener gaze upon the furrowed, shadowy face. Another of those strange desert prospectors in whom there was some relentless driving power besides the lust for gold! Cameron felt that between this man and himself there was a subtle affinity, vague and undefined, perhaps born of the divination that here was a desert wanderer like himself, perhaps born of a deeper, an unintelligible relation having its roots back in the past. A long-forgotten sensation stirred in Cameron’s breast, one so long forgotten that he could recognize it. But it was akin to pain.

When he awakened he found, to his surprise, that his companion had departed. A trail in the sand led off to the north. There was no water in that direction. Cameron shrugged his shoulders; it was not his affair; he had his own problems. And straightway he forgot his strange visitor.

Cameron began his day, grateful for the solitude that was now unbroken, for the canyon-furrowed and cactus-spired scene that now showed no sign of life. He traveled southwest, never straying far from the dry stream bed; and in a desultory way, without eagerness, he hunted for signs of gold.

The work was toilsome, yet the periods of rest in which he indulged were not taken because of fatigue. He rested to look, to listen, to feel. What the vast silent world meant to him had always been a mystical thing, which he felt in all its incalculable power, but never understood.

That day, while it was yet light, and he was digging in a moist white-bordered wash for water, he was brought sharply up by hearing the crack of hard hoofs on stone. There down the canyon came a man and a burro. Cameron recognized them.

“Hello, friend,” called the man, halting. “Our trails crossed again. That’s good.”

“Hello,” replied Cameron, slowly. “Any mineral sign to-day?”

“No.”

They made camp together, ate their frugal meal, smoked a pipe, and rolled in their blankets without exchanging many words. In the morning the same reticence, the same aloofness characterized the manner of both. But Cameron’s companion, when he had packed his burro and was ready to start, faced about and said: “We might stay together, if it’s all right with you.”

“I never take a partner,” replied Cameron.

“You’re alone; I’m alone,” said the other, mildly. “It’s a big place.
