"Melick," said Featherstone, "you're a volatile youth. You mustn't mind him, doctor. He's a professional cynic, sceptic, and scoffer. Oxenden and I, however, are open to conviction, and want to know more about those birds and beasts. Can you make anything out of the opmahera?" The doctor swallowed a glass of wine, and replied: "Oh yes; there are many birds, each of which may be the opmahera. There's the fossil bird of Massachusetts, of which nothing is left but the footprints; but some of these are eighteen inches in length, and show a stride of two yards. The bird belonged to the order of the Grallae, and may have been ten or twelve feet in height. Then there is the Gastornis parisiensis, which was as tall as an ostrich, as big as an ox, and belongs to the same order as the other. Then there is the Palapteryx, of which remains have been found in New Zealand, which was seven or eight feet in height. But the one which to my mind is the real counterpart of the opmahera is the Dinornis gigantea, whose remains are also found in New Zealand. It is the largest bird known, with long legs, a long neck, and short wings, useless for flight. One specimen that has been found is upward of thirteen feet in height. There is no reason why some should not have been much taller. More compares its height to that of a giraffe. The Maoris call this bird the Moa, and their legends and traditions are full of mention of it. When they first came to the island, six or seven hundred years ago, they found these vast birds everywhere, and hunted them for food. To my mind the dinornis is the opmahera of More. As to riding on them, that is likely enough; for ostriches are used for this purpose, and the dinornis must have been far stronger and fleeter than the ostrich. It is possible that some of these birds may still be living in the remoter parts of our hemisphere." "What about those monsters," asked Featherstone, "that More speaks of in the sacred hunt?" "I think," said the doctor, "that I understand pretty well what they were, and can identify them all. As the galley passed the estuary of that great river, you remember that he mentions seeing them on the shore. One may have been the Ichthyosaurus. This, as the name implies, is a fish-lizard. It has the head of a lizard, the snout of a dolphin, the teeth of an alligator, enormous eyes, whose membrane is strengthened by a bony frame, the vertebrae of fishes, sternum and shoulder-bones like those of the lizard, and the fins of a whale. Bayle calls it the whale of the saurians. Another may have been the Cheirotherium. On account of the hand-shaped marks made by its paws, Owen thinks that it was akin to the frogs; but it was a formidable monster, with head and jaws of a crocodile. Another may have been the Teleosaurus, which resembled our alligators. It was thirty-five feet in length. Then there was the Hylaeosaurus, a monster twenty-five feet in length, with a cuirass of bony plates."
