Forest, and he is quite as active by day as by night. He is pretty, especially when he sits up to eat, holding his food in his paws as does Happy Jack Squirrel. He makes his home in a burrow, the entrance to which is under an old stump, a rock or the root of a tree. His nest is of soft grass or moss. Sometimes he makes it in a hollow log or stump instead of digging a bedroom under ground. He is thrifty and lays up a supply of food in underground rooms, hollow logs and similar places. He eats seeds, small fruits, roots and various plants. Because of his preference for the Green Forest and the fact that he lives as a rule far from the homes of men, he does little real damage.
“There is still another little Redcoat in the family, and he is especially interesting because while he is related to Danny Meadow Mouse he lives almost wholly in trees. He is called the Rufous Tree Mouse. Rufous means reddish-brown, and he gets that name because of the color of his coat. He lives in the great forests of the Far West, where the trees are so big and tall that the biggest tree you have ever seen would look small beside them. And it is in those great trees that the Rufous Tree Mouse lives.
“Just why he took to living in trees no one knows, for he belongs to that branch of the family known as Ground Mice. But live in them he does, and he is quite as much at home in them as any Squirrel.”
Chatterer the Red Squirrel was interested right away. “Does he build a nest in a tree like a Squirrel?” he asked.
“He certainly does,” replied Old Mother Nature, “and often it is a most remarkable nest. In some sections he places it only in big trees, sometimes a hundred feet from the ground. In other sections it is placed in small trees and only a few feet above the ground. The high nests often are old deserted nests of Squirrels enlarged and built over. Some of them are very large indeed and have been used year after year. Each year they have been added to.
“One of these big nests will have several bedrooms and little passages running all through it. It appears that Mrs. Rufous usually has one of these big nests to herself, Rufous having a small nest of his own out on one of the branches. The big nest is close up against the trunk of the tree where several branches meet.”
“Does Rufous travel from one tree to another, or does he live in just one tree?” asked Happy Jack Squirrel.
“Wherever branches of one tree touch those of another, and you know in a thick forest this is frequently the case, he travels about freely if he wants to. But those trees are so big that I suspect he spends most of his time in the one in which his home is,” replied Old Mother Nature. “However, if an enemy appears in his home tree, he makes his escape by jumping from one tree to another, just as you would do.”
“What I want to know is where he gets his food if he spends all his time up in the trees,” spoke up Danny Meadow Mouse.
Old Mother Nature smiled. “Where should he get it but up where he lives?” she asked. “Rufous never has to worry about food. It is all around him. You see, so far as known, he lives wholly on the thick parts of the needles, which you know are the leaves, of fir and spruce trees, and on the bark of tender twigs. So you see he is more of a tree dweller than any of the Squirrel family. While Rufous has the general shape of Danny and his relatives, he has quite a long tail. Now I guess this will do for the nearest relatives of Danny Meadow Mouse.”
“He certainly has a lot of them,” remarked Whitefoot the Wood Mouse. Then he added a little wistfully, “Of course, in a way they are all cousins of mine, but I wish I had some a little more closely related.”
“You have,” replied Old Mother Nature, and Whitefoot pricked up his big ears. “One of them Bigear the Rock Mouse, who lives out in the mountains of the Far West. He is as fond of the rocks as Rufous is of the trees. Sometimes he lives in brush heaps and in brushy country, but he prefers rocks, and that is why he is known as the Rock Mouse.
“He is a pretty little fellow, if anything a trifle bigger than you, Whitefoot, and he is dressed much like you with a yellowish-brown coat and white waistcoat. He has just such a long tail covered with hair its whole length. But you should see his ears. He has the largest ears of any member of the whole family. That is why he is called Bigear. He likes best to be out at night, but often comes out on dull days. He eats seeds and small nuts and is especially fond of juniper seeds. He always lays up a supply of food for winter. Often he is found very high up on the mountains.
“Another of your cousins, Whitefoot, lives along the seashore of the East down in the Sunny South. He is called the Beach Mouse. In general appearance he is much like you, having the same shape, long tail and big ears, but he is a little smaller and his coat varies. When he lives back from the shore, in fields where the soil is dark, his upper coat is dark grayish-brown, but when he lives on the white sands of the seashore it is very light. His home is in short burrows in the ground.
“Now don't you little people think you have learned enough about the Mouse family?”
“You haven't told us about Nibbler the House Mouse yet. And you said you would,” protested Peter Rabbit.
“And when we were learning about Longfoot the Kangaroo Rat you said he was most closely related to the Pocket Mice. What about them?” said Johnny Chuck.
Old Mother Nature laughed. “I see,” said she, “that you want to know all there is to know. Be on hand to-morrow morning. I guess we can finish up with the Mouse family then and with them the order of Rodents to which all of you belong.”
Chapter XVIII
Mice with Pockets, and Others
“Pockets are very handy things for little people who are thrifty and who live largely on small seeds. Without pockets in which to carry the seeds, I am afraid some of them would never be able to store up enough food for winter,” began Old Mother Nature, as soon as everybody was on hand the next morning.
“I wouldn't be without my pockets for any thing,” spoke up Striped Chipmunk.
Old Mother Nature smiled. “You certainly do make good use of yours,” said she. “But there are others who have even greater need of pockets, and among them are the Pocket Mice. Of course, it is because of their pockets that they are called Pocket Mice. All of these pretty little fellows live in the dry parts of the Far West and Southwest in the same region where Longfoot the Kangaroo Rat lives. They are close neighbors and relatives of his.
“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,
