When resting the position of the feet and the arched back give them the appearance of a hairy ball. The tail is laid straight out from the body, if space will permit, or when the quarters are cramped it may be curled alongside the body. The tail is quite useful, as it is used as a sort of brace when the animal raises on its hind feet to view its surroundings. There are a number of species of these interesting rats. The first one was discovered and named in 1839. The species we illustrate was first found near San Diego and named Dipodomys similis in 1893. WINTER VISITORS. For several years I have been interested in birds. I have watched them through the glad nesting time of spring, have sought their quiet retreats in summer and have heard their faraway calls as they moved southward in the dark, cold, misty evenings of autumn; but for the first time I have succeeded in bringing them near enough to study them in winter. On the ledge of a second story window, out of the reach of cats, a wide shelf is fastened, and above it the branch of a dead cherry tree is securely wired to a shutter. On the shelf I scatter scraps from the table and shelled corn. To the branch, a long piece of suet is always bound with a cord. This is my free lunch table, spread for all my bird friends who wish to come. They have accepted the invitation beyond my expectation, and have fully repaid me for all the trouble it has been to prepare for them, in the pleasure their company gives me. I sit just inside the window and they appear not to notice me, so that I have an excellent opportunity to note their peculiarities. The one that comes every day and all day, is the tufted titmouse. He comes down with a whir, looks sharply about with his bright, black eyes, then takes a taste of the suet or marrow, and sometimes carries a crumb away. It is hard to tell how many of them come, as they all look so much alike. Not more than two or three ever come at once. A pair of downy woodpeckers are constant visitors at the meat table. They seldom come together, but sometimes it is the male with his bright red head spot, sometimes the female, in her plain black and white stripe. She is very plain, indeed, and somewhat more shy than her mate. If an English sparrow comes to the shelf while either of them is on the branch, it quickly drops down beside him as if to say, “See here, you are out of place,” and the sparrow leaves without a taste of the good things. Occasionally a winter wren, with his comical tail and delicate manners, calls on his way somewhere, and makes a pleasing variety in the appearance of the visitors. He eats all he needs of the bread crumbs before leaving, unless some sudden movement within startles him.
