They entered a region where mineral abounded, and their march became slower. Generally they took the course of a wash, one on each side, and let the burros travel leisurely along nipping at the bleached blades of scant grass, or at sage or cactus, while they searched in the canyons and under the ledges for signs of gold. When they found any rock that hinted of gold they picked off a piece and gave it a chemical test. The search was fascinating. They interspersed the work with long, restful moments when they looked afar down the vast reaches and smoky shingles to the line of dim mountains. Some impelling desire, not all the lure of gold, took them to the top of mesas and escarpments; and here, when they had dug and picked, they rested and gazed out at the wide prospect. Then, as the sun lost its heat and sank lowering to dent its red disk behind far-distant spurs, they halted in a shady canyon or likely spot in a dry wash and tried for water. When they found it they unpacked, gave drink to the tired burros, and turned them loose. Dead mesquite served for the campfire. While the strange twilight deepened into weird night they sat propped against stones, with eyes on the dying embers of the fire, and soon they lay on the sand with the light of white stars on their dark faces. Each succeeding day and night Cameron felt himself more and more drawn to this strange man. He found that after hours of burning toil he had insensibly grown nearer to his comrade. He reflected that after a few weeks in the desert he had always become a different man. In civilization, in the rough mining camps, he had been a prey to unrest and gloom. But once down on the great billowing sweep of this lonely world, he could look into his unquiet soul without bitterness. Did not the desert magnify men? Cameron believed that wild men in wild places, fighting cold, heat, starvation, thirst, barrenness, facing the elements in all their ferocity, usually retrograded, descended to the savage, lost all heart and soul and became mere brutes. Likewise he believed that men wandering or lost in the wilderness often reversed that brutal order of life and became noble, wonderful, super-human. So now he did not marvel at a slow stir stealing warmer along his veins, and at the premonition that perhaps he and this man, alone on the desert, driven there by life's mysterious and remorseless motive, were to see each other through God's eyes.
