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.
Balboa was greatly diverted by these barbacoas up in the air and their agile inhabitants. He endeavored to capture some of the latter, but they were too spry for him and his clumsy companions in armor, for, before they succeeded in landing, every member of the community was safely ensconced aloft. After the frightened Indians had scampered up the ladders they drew them into the tree-tops also, and, considering themselves secure, began to pelt the Spaniards with stones. This was more than their leader could endure, and, sheltering himself behind his buckler, he advanced to the tree in which, as he was told, the cacique's hut was built, and demanded that he descend immediately. The only answer was a shower of stones, some of which struck his shield, and one of them, glancing, wounded a companion. Becoming then enraged, Balboa ordered an arquebuse to be fired into the tree, and when the cacique, whose name was Abebeiba, heard the loud report and saw the cloud of smoke ascending, as from a volcano, he nearly fell from his lofty perch.
"Hold!" he cried, "I will descend"; but when his wives and family entreated him not to do so, he wavered, and finally refused to budge.
"What have I done to thee?" he asked of Balboa. "In nothing have I offended thee and thine; now leave me in peace."
The grim commander said nothing in reply, but commanded his axemen to attack the tree. "When the old scoundrel sees the chips fly," he remarked, "perhaps he may change his mind." Protected by the soldiers with their shields, the axemen vigorously set their blades into the palm-tree, and then the cacique seemed disposed to capitulate. Down rattled the long ladder, and it had scarcely struck the ground ere the cacique was there beside it, shaking with fear and chattering like a parrot. After him also came his wives and their children, in a long and rapidly descending procession, and soon they were grouped around the palm-tree, which, by their swift compliance with Balboa's demand, they had saved from destruction.
"We want gold," said Balboa, threateningly. "If you have any up in that tree, go back and get it at once."
The cacique replied: "I have no gold in the tree nor in any other place. I have no occasion for gold; but, great lord, if you will allow me to search in yonder sierras, I will soon return with a vast quantity, for there it exists and I know its hiding-place. Behold these wives of mine and these sons; they will be hostages for me against my return."
"It is well," answered Balboa. "Go, but return within two days. Meanwhile, we will hold your family as hostages, and enjoy the provisions you have so bountifully supplied against our coming, as it seems."
The wily Abebeiba departed for the sierras, and the Spaniards watched him out of sight. They saw him cross the river in his canoe, then plunge into a thicket on the opposite bank; but they saw him no more, for he never came back.
