As the brigantines were slowly forced against the current of the river, now beneath the overhanging branches of huge trees swarming with parrots, and again crossing the placid surface of an eddied lake, the excited soldiers caught occasional glimpses of large animals ahead climbing the trunks of trees. At first they took them for monkeys, and those of the band who had cross-bows got them ready to shoot; for the flesh of the monkey was held by them in great repute, and their supply of meat was exhausted. Suddenly one of the soldiers, who had climbed to the mast-head for better observation, cried out: "Those are not monkeys, but men! They are men and women and children; and behold, there are their barbacoas, like nests, perched up in the palms above the water!" And it was as the soldier had said, for there was a veritable nest of tree-dwellers, or rather a collection of nests, consisting of wicker-work huts made of flexible reeds and vines, fifty or sixty feet up in the air. They occupied the tops of the palm-trees, and each was large enough to accommodate a family, being divided into compartments, such as bedchamber, dining-room, and kitchen, or larder. They were reached by ladders made of split reeds or bamboos, which the Indians climbed with the agility of monkeys. Women and children, as well as men, went up and down the fragile, shaking ladders, some of them with great burdens on their backs, with as little inconvenience as if they were walking on level ground. All their provisions were kept in the aerial houses, which were well filled, but the liquors they drank, consisting of palm-wine and beer, were buried in earthen jars at the roots of the trees, as the rocking of the habitations would cause them to become turbid. The trees grew in or near the water, and the Indians kept canoes tied to their trunks, or to the lower ends of the ladders, and thus could embark without touching the earth. Their mode of life, in fact, was aerial and aquatic, rather than terrestrial, for they perched in the trees like birds, and sported in the water like fish, upon which latter they almost entirely subsisted. They rarely hunted the big game of the forest, and their chief reason for living up in the trees was that it afforded them security from wild beasts, especially the jaguars, which nightly roamed the woods in search of prey.
