Like a flitting shadow, a strange, sad smile crossed Señor’s face. Its meaning haunted Manuel, and recalled the early days of the trip, before the craze for rubber had driven all else from his mind. A wonderful change had come over Señor. He gave all his strength to the gathering of rubber, but no longer with a madness for sheer action. He no longer invited the torture of the stinging pests. He ate like a hungry man, and his sleep was untroubled. Even his silence had undergone change. The inward burning, the intensity of mind forever riveted upon the thing that had been the dividing spear of his life, had given place to austere tranquillity. Other enlightenment flashed into Manuel’s darksome thought. The fancy grew upon him that he had come to be to Señor what Señor was to him. He sensed it, felt it, finally realized it. Pondering this man’s deep influence, he tried to judge what it meant. Something shook his pulse, some power from without; some warm, living thing drew him to Señor. It was more than the intimate bond of men of like caliber, alone in the wilds, facing peril carelessly, dependent upon one another. Too subtle it was for Manuel, too mysterious for his crude reasoning; always it kept aloof, in the fringe of his mind. He floundered in thought, and seemed to go wandering in the realms of imagery, to become lost in memory, where the unreal present mingled with the actual past, through both of which ran Señor’s baffling, intangible hold on his heartstrings. “Maybe I’ve got a touch of fever,” he soliloquized. Another day went by, and still he hesitated to speak the word for departure. More and more the task grew harder, for added watching, thought, realization, strengthened his conviction that Señor intended to remain alone on the Palcazu. Had the man come to hide in the jungle, to face his soul in the solitude, to forget in the extremes of endurance? Yes, but more! He sought the end--annihilation! Manuel had never feared to use his tongue, yet now he could not speak. It was midday, and he lay beside Señor in the shack, sheltered from the torrid heat. Usually absolute silence prevailed at this hour. On this day, however, gentle gusts of wind beat the fronds of the palms. What a peculiar sound! It had no similarity to the muffled beating of the heart heard in the ear; yet it suggested that to Manuel, and wrought ominously upon his superstition. He listened. Sudden, soft gust--gentle beat, beat, beat hastening at the end! Was it the wind? How seldom had he heard wind in the jungle! Was it the fronds of the palms or the beating of his heart or of Señor’s? His blood did beat thick in his ears. Then a chill passed over him, a certainty of some calamity about to be, beyond his comprehension; and he wrenched decision out of his wavering will, and swore that he would start down the Palcazu on the morrow, if not with this strange companion, then alone.
