The flesh of the Tortoise is eaten, not only by human beings, but by birds, such as the lämmergeier. In order to get at the flesh of the Tortoise, they carry it high in the air and drop it on the ground so as to break the shell to pieces, should the reptile fall on a stone or rock. If, as is not often the case in such a rocky land as that of Palestine, it should fall on a soft spot, the bird picks it up, soars aloft, and drops it again.
The Tortoises have no teeth, but yet are able to crop the herbage with perfect ease. In lieu of teeth the edges of the jaws are sharp-edged and very hard, so that they cut anything that comes between them like a pair of shears. Leaves that are pulpy and crisp are bitten through at once, but those that are thin, tough, and fibrous are rather torn than bitten, the Tortoise placing its feet upon them, and dragging them to pieces with its jaws. The carnivorous Tortoises have a similar habit, as we shall presently see.
WATER TORTOISE.
This is the species from whose deliberate and slow movements the familiar metaphor of "slow as a Tortoise" was derived, and it is this species which is the hero of the popular fable of the "Hare and the Tortoise." Many of the reptiles are very slow in some things and astonishingly quick in others. Some of the lizards, for example, will at one time remain motionless for many hours together, or creep about with a slow and snail-like progress, while at others they dart from spot to spot with such rapidity that the eye can scarcely follow their movements. This however is not the case with the Tortoise, which is always slow, and, but for the defensive armour in which it is encased, would long ago have been extirpated.
During the whole of the summer months it may be seen crawling deliberately among the herbage, eating in the same deliberate style which characterises all its movements, and occasionally resting in the same spot for many hours together, apparently enjoying the warm beams of the sunshine.
As winter approaches, it slowly scrapes a deep hole in the ground, and buries itself until the following spring awakes it once more to active life. The depth of its burrow depends on the severity of the winter, for, as the cold increases, the Tortoise sinks itself more deeply into the earth.
Mention has been made of a species of Tortoise that inhabits the water. This is the Caspian Emys (Emys caspica), a small species, measuring about six inches in length. It belongs to the large family of the Terrapins, several of which are so well known in America, and has a long, retractile neck, very sharp jaws, and webbed feet, and a well-developed tail.
