We began to hope that we should find some of those saurians which science has succeeded in reconstructing from bits of bone or cartilage. I took up the telescope and carefully examined the horizon--looked over the whole sea; it was utterly and entirely deserted. Doubtless we were still too near the coast. After an examination of the ocean, I looked upward, towards the strange and mysterious sky. Why should not one of the birds reconstructed by the immortal Cuvier flap his stupendous wings aloft in the dull strata of subterranean air? It would, of course, find quite sufficient food from the fish in the sea. I gazed for some time upon the void above. It was as silent and as deserted as the shores we had but lately left. Nevertheless, though I could neither see nor discover anything, my imagination carried me away into wild hypotheses. I was in a kind of waking dream. I thought I saw on the surface of the water those enormous antediluvian turtles as big as floating islands. Upon those dull and somber shores passed a spectral row of the mammifers of early days, the great Liptotherium found in the cavernous hollow of the Brazilian hills, the Mesicotherium, a native of the glacial regions of Siberia. Farther on, the pachydermatous Lophrodon, that gigantic tapir, which concealed itself behind rocks, ready to do battle for its prey with the Anoplotherium, a singular animal partaking of the nature of the rhinoceros, the horse, the hippopotamus and the camel. There was the giant Mastodon, twisting and turning his horrid trunk, with which he crushed the rocks of the shore to powder, while the Megatherium--his back raised like a cat in a passion, his enormous claws stretched out, dug into the earth for food, at the same time that he awoke the sonorous echoes of the whole place with his terrible roar. Higher up still, the first monkey ever seen on the face of the globe clambered, gamboling and playing up the granite hills. Still farther away, ran the Pterodactyl, with the winged hand, gliding or rather sailing through the dense and compressed air like a huge bat. Above all, near the leaden granitic sky, were immense birds, more powerful than the cassowary and the ostrich, which spread their mighty wings and fluttered against the huge stone vault of the inland sea. I thought, such was the effect of my imagination, that I saw this whole tribe of antediluvian creatures. I carried myself back to far ages, long before man existed--when, in fact, the earth was in too imperfect a state for him to live upon it. My dream was of countless ages before the existence of man. The mammifers first disappeared, then the mighty birds, then the reptiles of the secondary period, presently the fish, the crustacea, the mollusks, and finally the vertebrata. The zoophytes of the period of transition in their turn sank into annihilation.
