“Several,” replied Old Mother Nature. “All are much alike in habits. One who lives a little farther north is called Brewer's Mole or the Hairytailed Mole. His tail is a little longer than Miner's and is covered with fine hair. The largest and handsomest member of the family is the Oregon Mole of the Northwest. His coat is very dark and his fur extremely fine. His ways are much the same as those of Miner whom you have just met, excepting that when he is tunneling deep in the ground he pushes the earth to the surface after the manner of Grubby Gopher, and his mounds become a nuisance to farmers. When he is tunneling just under the surface he makes ridges exactly like these of his eastern cousin. “But the oddest member of the Mole family is the Star-nosed Mole. He looks much like Miner with the exception of his nose and tail. His nose has a fringe of little fleshy points, twenty-two of them, like a many-pointed star. From this he gets his name. His tail is a little longer than Miner's and is hairy. During the late fall and winter this becomes much enlarged. “This funny little fellow with the star-like nose is especially fond of moist places, swamps, damp meadows, and the banks of streams. He is not at all afraid of the water and is a good swimmer. Sometimes he may be seen swimming under the ice in winter. He is seldom found where the earth is dry. For that matter, none of the family are found in those sections where there are long, dry periods and the earth becomes baked and hard. “The fur of Miner and his cousins will lay in either direction, which keeps it smooth no matter whether the wearer is going forward or backward. Otherwise it would be badly mussed up most of the time. Altogether these little underground workers are most interesting little people when you know them. But that is something few people have a chance to do. “Now just remember that the Shrews and the Moles belong to the order of Insectivora, meaning eaters of insects, and are the only two families in that order. And don't despise either of them, for they do a great deal of good in the Great World, more than some right here whom I might name, but will not. School is dismissed.” CHAPTER XXI Flitter the Bat and His Family In the dusk of early evening, as Peter Rabbit sat trying to make up his mind whether to spend that night at home in the dear Old Briar-patch with timid little Mrs. Peter or go over to the Green Forest in search of adventure, a very fine, squeaky voice which came right out of the air above him startled him for a moment. “Better stay at home, Peter Rabbit. Better stay at home to-night,” said the thin, squeaky voice. “Hello, Flitter!” exclaimed Peter, as he stared up at a little dark form darting this way, twisting that way, now up, now down, almost brushing Peter's head and then flying so high he could hardly be seen. “Why should I stay at home?”
