A peculiar formation of the incisors, or front teeth, groups a number of smaller animals together under the name of Rodentia, from the Latin word rodens, which signifies gnawing. These teeth act as files, so that the food on which their owners principally live is reduced by friction to a state which fits it for digestion. As the edges of these teeth become worn by constant use, they incessantly grow from the root. If one be broken, that opposite to it, in the other jaw, being deprived of its habitual wear and tear, grows so fast that it not only annoys its owner, but has caused his destruction by effectually closing the mouth. Their lower jaws can only move backwards and forwards; some exclusively eat vegetables, others eat all things, and others again prefer flesh. Some carry their food to their mouths with their paws, and climb trees; and, in many, the hinder limbs are so much longer than those in front, that they leap instead of walk. They are widely and numerously spread on the surface of the earth, and therefore bear strongly on its history; but it is not among them that we find the high intellectual development with which many other animals are gifted.
Squirrels are some of the most beautiful of the Rodentia, and chiefly live in trees. The fur of some of the species is extremely beautiful and valuable; they are very active, elegant little creatures, and easily tamed, when they become very playful and affectionate. A friend of mine was deprived of her only daughter, and the lost one's pet squirrel was of course cherished and loved; the little creature used to run up the lady's arm, and seat itself on her shoulder, caress her with its head, nestle itself into her neck, and drink her tears. As long as it lived, it was never caressed by the mother without first looking in her face for the drops, which it had been accustomed to remove.
These animals have a large bushy tail, the hair of which spreads out on each side like a feather; and by it they are guided and supported when they leap. The flying squirrels, as they are called, have an expansion of the skin of the sides, which extends between the hind and fore legs, by which they are suspended in the air when passing from tree to tree, and by it are enabled to go to greater distances without being actually able to fly, as their name would imply. The general colour of the English squirrel is red in summer; but in winter they often assume a grayish tint, at which time they have long pencils of hair at the top of their ears. This grey becomes more decided in more northern climates; and occasionally they are black. They always live in pairs, and sometimes are gregarious, inhabiting burrows. They lay up stores of provisions in different places; but they sleep the greater part of the cold months, their tail turned over them to keep them warm, having beforehand made a very elaborate nest of moss, leaves, and interlacing fibres in the hole of a tree, or the fork of two branches. They exclusively eat vegetable food, and are occasionally themselves eaten by the larger birds of prey.
Sir Francis Head gives us the following account of his meeting with a squirrel in Canada. "I was waiting the approach of a large flock of wild fowl; but a little villain of a squirrel on the bough of a tree close to me, seemed to have determined that even now I should not rest in quiet; for he sputtered and chattered with so much vehemence, that he attracted the attention of my dog. This was truly mortifying; for he kept his eyes fixed on the squirrel. With my hand I threatened the little beast; but he actually set up his back and defied me, becoming even more passionate than before; till, all of a sudden, as if purposely to alarm the game, he dropped plump within a couple of yards of Rover's nose. This was too much for the latter to bear, so he gave a bounce and sprang upon the impertinent squirrel; who, in a second, was out of his reach, cocking his tail and shewing his teeth, on the identical bough where he had sat before. Away flew all the wild fowl, and my sport was completely marred. My gun went involuntarily to my shoulder to shoot the squirrel; but I felt I was about to commit an act of sheer revenge on a courageous little animal, which deserved a better fate. As if aware of my hesitation, he nodded his head with rage, and stamped his fore paws on the tree; while in his chirruping, there was an intonation of sound, which seemed like contempt. What business had I there trespassing on his domain, and frightening his wife and little family, for whom he was ready to lay down his life? There he would sit in spite of me, and make my ears ring with the sound of his woo-whoop, till the spring of life should cease to bubble in his little heart."
It is from Captain Brown's pages that I extract the following. "A gentleman procured a squirrel from a nest, found at Woodhouse, near Edinburgh, which he reared and rendered extremely docile. It was kept in a box below an aperture, where was suspended a rope, by which the animal ascended and descended. The little creature used to watch very narrowly all its master's movements; and, whenever he was preparing to go out, it ran up his legs, and entered his pocket, from whence it would peep out at passengers as he walked along the streets, never venturing however to go out.
"But no sooner would he reach the outskirts of the city, than the squirrel leaped on the ground, ran along the road, ascended to the tops of trees and hedges with the quickness of lightning, and nibbled at the leaves and bark; and, if the gentleman walked on, it would descend, scamper after him, and again enter his pocket. Whenever it heard a carriage or cart, it became much alarmed, and always hid itself till they had passed by. This gentleman had a dog, between which and the squirrel, a certain enmity existed. Whenever the dog lay asleep, the squirrel showed its teasing disposition by rapidly descending from its box, scampering over the dog's body, and then quickly mounting its rope."
RATS.
Some persons profess to think that the Rodents called Rats are beautiful animals; and I presume that, prejudice apart, the sleek skin, the sharp head, the long, slender tail, and the keen look of their bright black eyes, ought to be attractions; but those who have been annoyed with these animals as I have been, can scarcely regard them with anything but dislike. Overspreading the whole world as they do, it is no wonder, where they are not vigorously checked, and where food is abundant, their numbers should amount to something frightful. On a visit to Sierra Leone, I was all day at the Government House, and going to an upper room to make my toilette, I heard a pattering of little feet close to me, and turning my head I saw between the floor and the shrunken door of the next apartment, a whole army of rats on a peregrination, and giving such an idea of number, that, uninitiated as I then was (it being on my first journey to Africa), I was perfectly appalled, and most thankful that I returned that night to sleep in my safer cabin on board ship. This, however, was but the beginning; and, in the next vessel which I entered, they were so numerous, that the next time she returned to port, she was sunk for a time, as the only means of getting rid of them. Between these creatures and the cockroaches, I thought my poor child and myself must be devoured.
