The round, yet delicate form of the Mouse, and the better expression of its countenance, make it an object much more worthy of admiration than the rat, of which it is but a diminished representative. It has the same destructive propensities, assembles also in vast numbers, and is equally carnivorous; but with all these, it is a more tamable and lovable animal. There is a white variety which is often nurtured as a pet. Mr. Darwin says, that with other small Rodents, numbers live together in nearly desert places, as long as there are a few blades of vegetation left; and that they swarm on the borders of salt-lakes, where not a drop of fresh water can be procured. Some of them lay up stores of food, especially those which inhabit northern countries. Field mice do an infinity of harm to young plantations, by nibbling off the young shoots, and, in order to catch them, pits from eighteen to twenty inches deep, are sunk in the soil, which are wider at the bottom than the top, so that they cannot easily get out. One hundred thousand were destroyed in this manner in the Forest of Dean, and about the same number in the New Forest. They make very beautiful round nests, of curiously I can bear witness to the possibility of taming mice, for I kept six in a box for several months, which were so well fed, that they did not attempt to gnaw their dwelling. I had a sort of little cart constructed for them, with bone buttons for wheels, and a packthread harness; and on being taken out of the box, they remained perfectly quiet till the harness was put upon them, and when that was done, they started at full gallop along the top of a square piano. Of course, care was taken to turn them back when they reached the end; but they soon learned to turn of their own accord, and performed their journey with as much regularity as well-trained horses. Death deprived me of my steeds; but I suspect it was in consequence of the injudicious cramming which I bestowed upon my favourites. During an illness of some week's duration, mice were to me a source both of amusement and annoyance; the former certainly predominating. A wainscot ledge ran round the room in which I lay, and it was their delight to scamper after one another upon this projection; but as the head of my curtain-less bed was close to it, they so frequently diverged on to my face, that I was obliged to have it drawn The head-quarters of my mice seemed to be a large closet in one corner of the room, from which they constantly issued, and to which they retreated on the least alarm, for it was always accessible, in consequence of the door not closing properly. They often appeared to me to hold a council, for they would sally forth in a body; not giddily, and as if by chance, but with all the gravity of diplomatic characters, and form a circle, when When I was allowed to eat, my appetite was kindly tempted by dainties sent to me by friends, and which were placed under tin covers, on the top of a chest of drawers. The endeavours of my rodent companions to get at these were excessively droll; but as fast as they clambered an inch or two up the sides, the slippery metal caused them to slide down again; then they thought if they could but get to the top of the cover, they should succeed; so they mounted upon each others' shoulders, and accomplished the feat, but not In an American scientific journal, there is a well-authenticated account of a strange and overpowering sensibility to music, as evinced by a mouse. It says, "that one evening, as a few officers on board a British man-of-war, in the harbour of Portsmouth, were seated round the fire, one of them began to play a plaintive air upon the violin. He had scarcely performed ten minutes, when a mouse, apparently frantic, made its appearance in the centre of the floor. The strange gestures of the little animal strongly excited the attention of the officers, who, with one consent, resolved to |
