“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.
