That the two animals should be thought to be merely two varieties of one species is not astonishing, when we remember the character of the people among whom the Porcupine lives. Not having the least idea of scientific geology, they look only to the most conspicuous characteristics, and because the Porcupine and hedgehog are both covered with an armature of quills, and the quills are far more conspicuous than the teeth, the inhabitants of Palestine naturally class the two animals together. In reality, they belong to two very different orders, the hedgehog being classed with the shrew-mice and moles, while the Porcupine is a rodent animal, and is classed with the rats, rabbits, beavers, marmots, and other rodents. It is quite as common in Palestine as the hedgehog, a fact which increases the probability that the two animals may have been mentioned under a common title. Being a nocturnal animal, it retires during the day-time to some crevice in a rock or burrow in the ground, and there lies sleeping until the sunset awakens it and calls it to action. And as the hedgehog is also a nocturnal animal, the similarity of habit serves to strengthen the mutual resemblance. The Porcupine is peculiarly fitted for living in dry and unwatered spots, as, like many other animals, of which our common rabbit is a familiar example, it can exist without water, obtaining the needful moisture from the succulent roots on which it feeds. The sharply pointed quills with which its body is covered are solid, and strengthened in a most beautiful manner by internal ribs, that run longitudinally through them, exactly like those of the hollow iron masts, which are now coming so much into use. As they are, in fact, greatly developed hairs, they are continually shed and replaced, and when they are about to fall are so loosely attached that they fall off if pulled slightly, or even if the animal shakes itself. Consequently the shed quills that lie about the localities inhabited by the Porcupine indicate its whereabouts, and so plentiful are these quills in some places, that quite a bundle can be collected in a short time. There are many species of Porcupines which inhabit different parts of the world, but that which has been mentioned is the common Porcupine of Europe, Asia, and Africa. THE MOLE.
