They packed the supplies up from the river to escape the sand flies, and built a shack, elevating it slightly on forked sticks to evade the marching ants and creeping insects. Inside the palm-leaf walls they hung the net, fitting it snugly in the cramped space. By clearing away the underbrush and burning the ground bare, they added still more to the utility of their camp site, and, as far as it was possible in that jungle, approached comfort. A troop of monkeys took refuge in the tops of some palms and set up a resentful chattering; parrots and macaws swelled the unwelcoming chorus; a boa wound away from the spot, shaking a long line of bushes; and an anteater ran off into the _sitekas_. Manuel caught up his gun, making as if to pursue the beast, then slowly laid the weapon down. “I’d forgotten. We’re in Cashibos country now. I’ve seen no signs, but we had best be quiet. At that we may have to shoot the jaguars. They stalk a man.” The rubber hunters worked from dawn till the noonday heat, rested through the white, intense hours, resumed their tasks in the afternoon, and continued while the light lasted. The method of honest rubber hunters was to tap a tree in the evening and visit it the next morning to get the juice. This was too slow a process for Manuel--as it took several days for a flow of a few ounces. He was possessed with exceeding skill in the construction of clay vessels to catch the milky juice and in extracting rubber. He carried water from the river and fashioned large clay repositories, one for so many rubber trees; also he made small vessels and troughs. These baked hard in the sun. Then he cut the trees so the sap would flow freely. They would die; but that was of no moment to the outlaw. He had brought a number of kettles, in which he made a thick steam by heating palm nuts. Taking a stick with a clay mold on the end, he dipped it first in the milk, and then dried the milk in the stream. From a vessel full of milk, he got one third its weight in rubber. “Señor,” he said proudly, “I can make a hundred pounds of rubber in a day.” It was a toil-filled time, in which the united efforts of Manuel and Señor were given to making an immense cargo of rubber. Swiftly the days passed into weeks, the weeks summed months, and the rainy season was at hand. Soon the rubber hunters must expect a daily deluge, a flooded, sticky forest, intolerable humidity, and sun like an open furnace door. Manuel awoke from his lust for rubber. “The canoe won’t hold another layer,” he said. “She’ll be loggy enough now. We can rest and drift clear to Iquitos. How good! We must be starting.”
