On crossing these woody eminences, the forlorn adventurers would plunge into ravines of frightful depth, where the exhalations of a humid soil steamed up amidst the incense of sweet-scented flowers, which shone through the deep glooms in every conceivable variety of color. Birds, especially of the parrot tribe, mocked this fantastic variety of nature with tints as brilliant as those of the vegetable world. Monkeys chattered in crowds above their heads, and made grimaces like the fiendish spirits of these solitudes; while hideous reptiles, engendered in the slimy depths of the pools, gathered round the footsteps of the wanderers. Here was seen the gigantic boa, coiling his unwieldy folds about the trees, so as hardly to be distinguished from their trunks, till he was ready to dart upon his prey; and alligators lay basking on the borders of the streams, or, gliding under the waters, seized their incautious victim before he was aware of their approach.17 Many of the Spaniards perished miserably in this way, and others were waylaid by the natives, who kept a jealous eye on their movements, and availed themselves of every opportunity to take them at advantage. Fourteen of Pizarro's men were cut off at once in a canoe which had stranded on the bank of a stream.18 Famine came in addition to other troubles, and it was with difficulty that they found the means of sustaining life on the scanty fare of the forest,-- occasionally the potato, as it grew without cultivation, or the wild cocoa- nut, or, on the shore, the salt and bitter fruit of the mangrove; though the shore was less tolerable than the forest, from the swarms of mosquitos which compelled the wretched adventurers to bury their bodies up to their very faces in the sand. In this extremity of suffering, they thought only of return; and all schemes of avarice and ambition--except with Pizarro and a few dauntless spirits--were exchanged for the one craving desire to return to Panama.
