"Why," asked Cortlandt, "if the hunting parties that have been in our vicinity were only beaters, should they have mutilated the mastodon in such a way that he could not walk? And how were they able to take themselves off so quickly--for man in his natural state has never been a fast mover? I repeat, it will upset my theories if we find men."

It was obvious to them that tortoises were not much troubled by the apparently general foe, for the specimen in which they were just then interested continued his course entirely unconcerned. Soon, however, he seemed to feel fatigue, for he drew his feet and head within his shell, which he tightly closed, and after that no poking or prodding had the desired effect.

"I suspect we must depend on shank's mares for a time," said Bearwarden, cheerfully, as they scrambled down.

"We can now see," said Cortlandt, "why our friend was so unconcerned, since he has but to draw himself within himself to become invulnerable to anything short of a stroke of lightning; for no bird could have power enough to raise and drop him from a great height upon rocks, as the eagles do on earth."

"I suspect, if anxious for turtle soup," said Bearwarden, "we must attach a lightning--rod, and wait for a thunderstorm to electrocute him."

SPORTSMEN'S REVERIES.

Feeling grateful to the huge tortoise for the good service he had rendered, they shot a number of the great snakes that were gliding about on the ground, and placed them where he would find them on awaiting. They then picked their way carefully towards stretches on which the grass was shortest. When they had gone about two miles, and had already reached higher ground, they came to a ridge of rock running at right angles to their course. This they climbed, and on looking over the edge of the crest beheld a sight that made their hearts stand still. A monster, somewhat resembling an alligator, except that the back was arched, was waddling about perhaps seventy-five yards from them. It was sixty feet long, and to the top of its scales was at least twenty-five feet high. It was constantly moving, and the travellers noticed with some dismay that its motion was far more rapid than they would have supposed it could be.

"It is also a dinosaur," said the professor, watching it sharply, "and very closely resembles the Stegosaurus ungulatus restored in the museums. The question is, What shall we do with the living specimen, now that we have it?"
