The sufferings of our two companions were so much alleviated by the application of water that they soon came and sat beside us. I can not describe the proud enjoyment we all felt in this wild spot. We were face to face with this unknown cascade, which we were, perhaps, the first Europeans to contemplate. Behind us the mountain sides seemed to unite and hem in the bed of the torrent. The sun bathed with its rays that portion which was bordered with large trees, among which kingfishers were skimming about. One of these birds came and perched close to us--its breast was white, its wings black on the upper side, and its head-feathers dark green; its stout, thick-set shape, and its short tail, made Lucien remark that it looked like a malformed creature. Always restless, it almost immediately resumed its abrupt flight over the surface of the water, and disappeared among the windings of the ravine. Lucien pointed out to me an immense willow, the branches of which, drooping over the water, seemed to have at their ends enormous gourd-shaped fruits. I recognized in them the nests of those beautiful yellow birds, spotted with black, which the Mexicans call _calandres_. To convince Lucien of his mistake, l'Encuerado threw a large stone into the tree; the missile fell from branch to branch, and more than a hundred frightened birds flew out from their curious retreats. At first they appeared much alarmed; but when this had subsided, they skimmed over the water, or entered their impregnable habitations. [Illustration: Fall of Ingenio (from a drawing by the Marquis of Radepoint).] We made our way down the ravine in hopes of finding a resting-place less rugged, and after a long, winding, tedious course, came upon a sheet of calm water, flowing over a bed of sand. The sun was shining full open upon its transparent surface, and, close to the edge, hundreds of flies were whirling about. "Those are coleopterae," said Sumichrast to Lucien. "Why do they turn round and round like that?" inquired he. "To find their food, for they are carnivorous, and require a great deal of nourishment. In France they are commonly called _tourniquets_, or _water-fleas_." Lucien wanted to catch one, but could not succeed; l'Encuerado and Sumichrast joined in the pursuit. At first I amused myself with watching the useless efforts of my companions; but at last, thinking myself cleverer than they, I squatted down also. There we all four were, with our hands in the water, perfectly motionless, and holding our breath, the better to remain motionless. The insects were all in a close mass, and whirling round like a living mosaic, moving in every direction without separating; but however quickly we raised our hands, we all failed in our efforts.
