The Mole-rat does not keep itself quite so jealously secluded as does our common Mole, but occasionally will come out of the burrow and lie on the ground, enjoying the warm sunshine. Still it is not easily to be approached; for though its eyes are almost useless, the ears are so sharp, and the animal is so wary, that at the sound of a footstep it instantly seeks the protection of its burrow, where it may bid defiance to its foes.
How it obtains its food is a mystery. There seems to be absolutely no method of guiding itself to the precise spot where a bulb may be growing. It is not difficult to conjecture the method by which the Mole discovers its prey. Its sensitive ears may direct it to the spot where a worm is driving its way through the earth, and should it come upon its prey, the very touch of the worm, writhing in terror at the approach of its enemy, would be sufficient to act as a guide. I have kept several Moles, and always noticed that, though they would pass close to a worm without seeming to detect its presence, either by sight or scent, at the slightest touch they would spring round, dart on the worm, and in a moment seize it between their jaws. But with the Mole-rat the case is different. The root can utter no sound, and can make no movement, nor is it likely that the odour of the bulb should penetrate through the earth to a very great distance.
THE MOUSE.
The Mice which marred the land—The Field-mouse—Its destructive habits and prolific nature—The Hamster, and its habits—The Jerboa, its activity and destructiveness—Various species of Dormice and Sand-rats.
That the Mouse mentioned in the Old Testament was some species of rodent animal is tolerably clear, though it is impossible to state any particular species as being signified by the Hebrew word Akbar. The probable derivation of this name is from two words which signify "destruction of corn," and it is therefore evident that allusion is made to some animal which devours the produce of the fields, and which exists in sufficient numbers to make its voracity formidable.
