Toward sunset Manuel beached on a sandy bank, where there was a grove of _siteka_ trees. He had gone into the jungle at this point and brought out rubber. The camp site was now waist deep in vegetation, which Manuel mowed down with his machete. Then he built two fires of damp leaves and wood, so they would smoke and somewhat lessen the scourge of mosquitoes. After that he carried up the charcoal box from the canoe and cooked the evening meal. Manuel found it good to unseal the fountain of speech, that always went dry when he was alone in the jungle. It took him a little while to realize that he did all the talking, that Señor was a silent man who replied only to a direct question, and then mostly in monosyllables. Slowly this dawned upon the voluble Spaniard, and slowly he froze into the silence natural to him in the wilderness. They finished the meal, eating under their head nets, and then sat a while over the smoky fires, with the splash of fish and the incessant whining hum of mosquitoes in their ears. When the stars came out, lightening the ebony darkness, they manned the canoe again, and for long hours poled up the misty gloom of the river. In the morning they resumed travel, slept through the sweltering noon, and went on in the night. At the end of the fifth day’s advance, Manuel pointed out the mouth of a small tributary. “So far I’ve been. Beyond here all is strange to me. White men from Lima have come down the river; but of those who have gone up farther than this, none have ever returned.” What a light flashed from the eyes of his partner! Manuel was slow to see anything singular in men. But this served to focus his mind on the strangest companion with whom he had ever traveled. Señor was exceedingly strong and implacably tireless; a perfect fiend for action. He minded not the toil, nor the flies, nor the mosquitoes, nor the heat; nothing concerned him except standing still. Señor never lagged, never shirked his part of the labor, never stole the bigger share of food, which was more than remarkable in the partner of a rubber hunter. So Manuel passed through stages of attention, from a vague stirring of interest to respect and admiration, and from these to wonder and liking, emotions long dormant within him. The result was for him to become absorbed in covert observation of his strange comrade. Señor ate little, and appeared to force that. He slept only a few hours every day, and his slumbers were restless, broken by turning and mumbling. Sometimes Manuel awakened to find him pacing the canoe or along a sandy strip of shore. All the hot hours of their toil he bent his broad shoulders to the paddle, wet with sweat. Indeed, he invited the torture of the sun and flies. His white face, that Manuel likened to a woman’s, was burned red and bitten black and streaked with blood.
