The shrew mouse, especially in winter, fixes its residence in stables, hay-lofts, or barns; it feeds on grain, insects, and putrid flesh. It also resides in woods and fields, where it lives on grain; it sometimes conceals itself under moss, leaves, the trunks of trees, and sometimes in holes abandoned by moles, or in holes of a smaller size, which it digs for itself, with its claws and snout. The shrew produces, it is said, as many young at a time as the common mouse, but not so frequently. Its cry is more sharp, but it is not near so nimble, and as it sees imperfectly, and runs slowly, there is very little difficulty in taking it. Their usual colour is brown mixed with red, though some are ash-coloured, and all of them are white under the belly. They are very common throughout Europe, but do not seem to exist in America. The animal of Brasil, which Marcgrave mentions as the shrew mouse, and describes with three black stripes upon the back, is larger, and appears to be of a different species.
THE WATER SHREW MOUSE.
This animal, though a native of these climates, was unknown to any of our naturalists, until M. Daubenton first discovered and described it in the Memoires de l’Academie, in 1756. To the former animal we have only to add, that this is taken near the source of fountains, as the sun rises and sets; that in the day it remains concealed in the clefts of rocks, or in holes at the edges of rivulets; that it brings forth in spring, and has generally nine young ones at a time.
THE MOLE.
The mole, ([fig. 82.]) without being blind, has eyes so small, and so concealed, that it can make but little use of seeing, but in recompence Nature has supplied it with an ample portion of the sixth sense. Of all animals the mole is the most profusely furnished with generic organs, and of course with the relative sensations. The senses of hearing and feeling it enjoys in an eminent degree; a skin as soft as velvet, and its little paws, with five claws, are very different from other quadrupeds, and nearly resemble the hand of a human being; they have great strength in proportion to the size of their bodies, and so strong and reciprocal an attachment subsists between the male and female, that they seem to have a dread of, and a disgust to, all other society. They enjoy the mild habitudes of solitude and repose; the art of securing themselves, of instantaneously forming an asylum, of extending it, and of obtaining a plentiful subsistence without a necessity for relinquishing it. Such are the dispositions, manners, and talents, of this animal, and they doubtless are preferable to qualities more brilliant, which are perhaps more incompatible with happiness than even an absolute deprivation of sight.
The mole shuts up the entrance to its retreat, which it seldom leaves, unless forced by heavy rains, or it becomes demolished by man. It prefers cultivated grounds, and is never to be found in those which are muddy, hard, or stony; and delights in a soft soil, well supplied with esculent roots, insects and worms, of which its principal nourishment consists. As they seldom come above ground they have but few enemies, and easily elude the pursuit of carnivorous animals. Their greatest calamity is an inundation, and when that happens, they are seen swimming in great numbers, and using every effort to save themselves by reaching the high grounds; but the greatest part of them perish, as well as their young who remain in the holes. Were it not for such accidents, from their great fecundity, they would be extremely incommodious to farmers. They couple at the beginning of spring, and their young ones are found as early as May. They generally have four or five at a time, and it is easy to distinguish the mole-hill under which they have littered, as they are more elevated, and made with greater art than the rest. I am inclined to think they bring forth more than once a year, but I cannot absolutely assert it; this however is certain, that young ones are met with from April to August, which, however, may be owing to some coupling later in the year than others.
The hole in which they deposit their young is formed with singular skill and deserves a particular description. They begin by raising the earth and forming a tolerably ample roof, leaving divisions or pillars at certain distances to support it, all round which they beat and press the earth, interweave it with roots and plants, and render it so firm that the water cannot penetrate it; the apartment in the hillock is above the level of the ground, and therefore less subject to accidents from slight inundations; under this they form another kind of hill, upon the top of which they lay grass and leaves as a bed for their young. Here they lay secure from wet, and the female proceeds to make their retreat equally free from danger; for all round this internal hillock she pierces holes still deeper, which part from the middle apartment like rays from a centre, and extend about fifteen feet in every direction; into these the mother makes her subterraneous excursions, and from them supplies her young with roots and insects; but they contribute still more to the general safety, for as the mole is very quick of hearing, the instant she finds her habitation attacked she takes to one of the burrows, and unless the earth be dug away by several men at once, she and her young always make good their retreat.
Some authors have asserted that the mole and badger sleep the whole winter: but that this is not true with respect to the badger, we have already observed, from the traces which he leaves upon the snow; and so far is the mole from sleeping the whole winter, that she continues to raise the earth then as well as in the summer; and it is almost proverbial with the peasantry of France, that “when the mole is at work a thaw is at hand.” They are indeed fond of warm places, and the gardeners often catch them round their beds in the months of December, January, and February. This animal is never to be met with in barren deserts or cold climates, where the ground is frozen for the greatest part of the year. The Siberian mole, with green and yellow hair, is of a different species from our mole, which abounds only from Sweden to Barbary; at least from the silence of travellers we may presume it is not an inhabitant of hot climates. The moles of America, particularly the red ones, are also different. The Virginian mole, however, is not unlike ours, except in the colour of the hair, which is mixed with a deep purple. In our common moles there are only two or three varieties; some are more or less brown or black, and some few we have seen entirely white. Seba mentions, and gives a figure of a mole with black and white spots[P], which he found in East Friesland, and which was rather larger than our moles.
[P] This mole, says he, was found on the highway. It is a little longer than the common mole, from which it differs in no respect but the colour of the skin, which is diversified on the back and the belly with black and white spots, and these intermixed with a few grey hairs as fine as silk. The snout of this animal is long, and covered with hair of a considerable length; and its eyes are so small that it is difficult to distinguish them.—Albert Seba, vol. I. p. 63.
