Then the silence! He was dumb, he was awed, he bowed his head, he trembled, he marveled at the desert silence. It was the one thing always present. Even when the wind roared there seemed to be silence. But at night, in this lava world of ashes and canker, he waited for this terrible strangeness of nature to come to him with the secret. He seemed at once a little child and a strong man, and something very old. What tortured him was the incomprehensibility that the vaster the space the greater the silence! At one moment Gale felt there was only death here, and that was the secret; at another he heard the slow beat of a mighty heart. He came at length to realize that the desert was a teacher. He did not realize all that he had learned, but he was a different man. And when he decided upon that, he was not thinking of the slow, sure call to the primal instincts of man; he was thinking that the desert, as much as he had experienced and no more, would absolutely overturn the whole scale of a man's values, break old habits, form new ones, remake him. More of desert experience, Gale believe, would be too much for intellect. The desert did not breed civilized man, and that made Gale ponder over a strange thought: after all, was the civilized man inferior to the savage? Yaqui was the answer to that. When Gale acknowledged this he always remembered his present strange manner of thought. The past, the old order of mind, seemed as remote as this desert world was from the haunts of civilized men. A man must know a savage as Gale knew Yaqui before he could speak authoritatively, and then something stilled his tongue. In the first stage of Gale's observation of Yaqui he had marked tenaciousness of life, stoicism, endurance, strength. These were the attributes of the desert. But what of that second stage wherein the Indian had loomed up a colossal figure of strange honor, loyalty, love? Gale doubted his convictions and scorned himself for doubting. There in the gloom sat the silent, impassive, inscrutable Yaqui. His dark face, his dark eyes were plain in the light of the stars. Always he was near Gale, unobtrusive, shadowy, but there. Why? Gale absolutely could not doubt that the Indian had heart as well as mind. Yaqui had from the very first stood between Gale and accident, toil, peril. It was his own choosing. Gale could not change him or thwart him. He understood the Indian's idea of obligation and sacred duty. But there was more, and that baffled Gale. In the night hours, alone on the slope, Gale felt in Yaqui, as he felt the mighty throb of that desert pulse, a something that drew him irresistibly to the Indian. Sometimes he looked around to find the Indian, to dispel these strange, pressing thoughts of unreality, and it was never in vain.
