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. Conjectures as to the right translation of the Hebrew word _Akbar_--Signification of the word--The Mice which marred the land--Miracles, and their economy of power--The Field-mouse--Its destructive habits and prolific nature--The insidious nature of its attacks, and its power of escaping observation--The Hamster, and its habits--Its custom of storing up provisions for the winter--Its fertility and unsociable nature--The Jerboa, its activity and destructiveness--Jerboas and Hamsters eaten by Arabs and Syrians--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. Some commentators on the Old Testament translate the word Akbar as jerboa. Now, although the jerboa is common in Syria, it is not nearly so plentiful as other rodent animals, and would scarcely be selected as the means by which a terrible disaster is made to befall a whole country. The student of Scripture is well aware that, in those exceptional occurrences which are called miracles, a needless development of the wonder-working power is never employed. We are not to suppose, for example, that the clouds of locusts that devoured the harvests of the Egyptians were created for this express purpose, but that their already existing hosts were concentrated upon a limited area, instead of being spread over a large surface. Nor need we fancy that the frogs which rendered their habitations unclean, and contaminated their food, were brought into existence simply to inflict a severe punishment on the fastidious and superstitious Egyptians.
