“Midget the Silky Pocket Mouse is one of the smallest animals in all the Great World, so small that Whitefoot the Wood Mouse is a giant compared with him. He weighs less than an ounce and is a dear little fellow. His back and sides are yellow, and beneath he is white. He has quite long hind legs and a long tail, and these show at once that he is a jumper. In each cheek is a pocket opening from the outside, and these pockets are lined with hair. He is called Silky Pocket Mouse because of the fineness and softness of his coat. He has some larger cousins, one of them being a little bigger than Nibbler the House Mouse. Neighbors and close relatives are the Spiny Pocket Mice.”

“Do they have spines like Prickly Porky?” demanded Peter Rabbit.

Old Mother Nature laughed. “I don't wonder you ask,” said she. “I think it is a foolish name myself, for they haven't any spines at all. Their fur isn't as fine as that of Midget, and it has all through it long coarse hairs almost like bristles, and from these they get their name. The smallest of the Spiny Pocket Mice is about the size of Nibbler the House Mouse and the largest is twice as big. They are more slender than their Silky cousins, and their tails are longer in proportion to their size and have little tufts of hair at the ends. Of course, they have pockets in their cheeks.

“In habits all the Pocket Mice are much alike. They make burrows in the ground, often throwing up a little mound with several entrances which lead to a central passageway connecting with the bedroom and storerooms. By day the entrances are closed with earth from inside, for the Mice are active only at night. Sometimes the burrows are hidden under bushes, and sometimes they are right out in the open. Living as they do in a hot, dry country, the Pocket Mice have learned to get along without drinking water. Their food consists mainly of a variety of small seeds.

“Another Mouse of the West looks almost enough like Whitefoot to be a member of his branch of the family. He has a beautiful yellowish-brown coat and white waistcoat, and his feet are white. But his tail is short in comparison with Whitefoot's and instead of being slim is quite thick. His fur is like velvet. He is called the Grasshopper Mouse.”

“Is that because he eats Grasshoppers?” asked Peter Rabbit at once.

“You've guessed it,” laughed Old Mother Nature. “He is very, very fond of Grasshoppers and Crickets. He eats many kinds of insects, Moths, Flies, Cutworms, Beetles, Lizards, Frogs and Scorpions. Because of his fondness for the latter he is called the Scorpion Mouse in some sections. He is fond of meat when he can get it. He also eats seeds of many kinds. He is found all over the West from well up in the North to the hot dry regions of the Southwest. When he cannot find a convenient deserted burrow of some other animal, he digs a home for himself and there raises several families each year. In the early evening he often utters a fine, shrill, whistling call note.

“Another little member of the Mouse family found clear across the country is the Harvest Mouse. He is never bigger than Nibbler the House Mouse and often is much smaller. In fact, he is one of the smallest of the entire family. In appearance he is much like Nibbler, but his coat is browner and there are fine hairs on his tail. He loves grassy, weedy or brushy places.

“As a rule he does little harm to man, for his food is chiefly seeds of weeds, small wild fruits and parts of wild plants of no value to man. Once in a while his family becomes so large that they do some damage in grain fields. But this does not happen often. The most interesting thing about this little Mouse is the way he builds his home. Sometimes he uses a hole in a tree or post and sometimes a deserted birds' nest, but more frequently he builds a nest for himself—a little round ball of grass and other vegetable matter. This is placed in thick grass or weeds close to the ground or in bushes or low trees several feet from the ground.

“They are well-built little houses and have one or more little doorways on the under side when they are in bushes or trees. Inside is a warm, soft bed made of milkweed or cattail down, the very nicest kind of a bed for the babies. No one has a neater home than the Harvest Mouse. He is quite as much at home in bushes and low trees as Happy Jack Squirrel is in bigger trees. His long tail comes in very handy then, for he often wraps it around a twig to make his footing more secure.
