knees bend backward in an opposite direction from ours. This renders him unable to walk, and when attempting to do so, he has the appeairance of "scrabbling" along on his feet and elbows. When thus movng he keeps his wings fluttering rapidly, as if feeling his way in the dark, and his movements are trembly. He uses his teeth to aid in climbing. The little brown bat's wings often measure nine inches from tip to tip, and yet he folds them so that they scarcely show, he does not fold them like a fan, but rather like a pocket knife. The hind legs merely act as a support for the side wing, and the little hip bones look pitifully sharp; the membrane reaches only to the ankle, the tiny emaciated foot projecting from it is armed with five, wirelike toes, tipped with sharp hooked claws. It is by these claws that he hangs when resting during the day, for he is upside-down-y in his sleeping habits, slumbering during the daytime, while hanging head downward, without any inconvenience from a rush of blood to the brain; when thus suspended, the tail is folded down. Sometimes he hangs by one hind foot and a front hook; and he is a wee thing when all folded together and hung up, with his nose tucked between his hooked thumbs, in a very babyish fashion. The bat is very particular about his personal cleanliness. People who regard the bat as a dirty creature, had better look to it that they are even half as fastidious as he. He washes his face with the front part of his wing, and then licks his wash-cloth clean; he scratches the back of his head with his hind foot and then licks the foot; when hanging head down, he will reach one hind foot down and scratch behind his ear with an aplomb truly comical in such a mite; but it is most fun of all to see him clean his wings; he seizes the edges in his mouth and stretches and licks the membrane until we are sure it is made of silk elastic, for he pulls and hauls it in a way truly amazing. The bat has a voice which sounds like the squeak of a toy wheelbarrow, and yet it is expressive of emotions. He squeaks in one tone when holding conversation with other bats, and squeaks quite differently when seized by the enemy. The mother bat feeds her little ones from her breasts as a mouse does its young, only she cradles them in her soft wings while so doing; often she takes them with her when she goes out for insects in the evenings; they cling to her neck during these exciting rides; but when she wishes to work unencumbered, she hangs her tiny youngsters on some twig and goes back to them later. The little ones are born in July and usually occur as twins. During the winter, bats hibernate like woodchucks or chipmunks. They select for winter quarters some hollow tree or cave or other protected place. They go to sleep when the cold weather comes, and do not awake until the insects are flying; they then come forth in the evenings, or perhaps early in the morning, and do their best to rid the world of mosquitoes and other insect nuisances. There are many senseless fears about the bat; for instance, that he likes to get tangled in a lady's tresses, a situation which would frighten him far more than the lady; or that he brings bedbugs into the house, when he enters on his quest for mosquitoes, which is an ungrateful slander. Some people believe that all bats are vampires, and only await an opportunity to suck blood from their victims. It is true that in South America there are two species which occasionally attack people who are careless enough to sleep with their toes uncovered, but feet thus injured seem to recover speedily; and these bats do little damage to people, although they sometimes pester animals; but there are no vampires in the United States. Our bats, on the contrary, are innocent and beneficial to man; and if we had more of them we should have less malaria. There a few species in our country, which have little, leaf-like growths on the end of the nose; and when scientists study the bat from a nature-study instead of an anatomical standpoint, we shall know what these leafy appendages are used for. Leading thought-Although the bat's wings are very different from those of the bird's yet it is a rapid and agile flier. It flies in the dusk and catches great numbers of mosquitoes and other troublesome insects, upon which it feeds. Method-This lesson should not be given unless there is a live bat to illustrate it; the little creature can be cared for comfortably in a cage in the schoolroom, as it will soon learn to take flies or bits of raw meat when presented on the point of a pencil or toothpick. Any bat will do for this study, although the little brown bat is the one on which my observations were made. Observations-1. At what time of day do we see bats flying? Describe how the bat's flight differs from that of birds. Why do bats dart about so rapidly? 2. Look at a captive bat and describe its wings. Can you see what makes the framework of the wings? Do you see the three finger bones extending out into the wings? How do the hind legs support the wing? The tail? Is the wing membrane covered with fur? Is it thick and leathery or thin and silky and elastic? How does the bat fold up its wings? 3. In what position does the bat rest? Does it ever hang by his thumb hooks? 4. Can you see whether the knees of the hind legs bend upward or downward? How does the bat act when trying to walk or crawl? How does it use its thumb hooks in doing this? 5. What does the bat do daytimes? Where does it stay during the day? Do many bats congregate together in their roosts? 6. Describe the bat's head, including the ears, eyes, nose and mouth. What is its general expression? Do you think it can see and hear well? How is its mouth fitted for catching insects? Does it shut its mouth while chewing or keep it open? Do you think that bats can see by daylight? 7. What noises does a bat make? How does it act if you try to touch it? Can it bite severely? Can you understand why the Germans call it a flitter-mouse? 8. Do you know how the mother bat cares for her young? How does she carry them? At what time of year may we expect to find them? 9. When making its toilet, how does a bat clean its wings? Its face? Its back? Its feet? Do you know if it is very clean in his habits? IO. How and where do the bats pass the winter? How are they beneficial to us? Are they ever harmful? Supplementary reading-American Animals, Stone and Cram. Nature-study should not be unrelated to the child's life and circumstances. It stands for directness and naturalness. It is astonishing when one comes to think of it, how indirect and how remote from the lives of pupils much of our education has been. Geography still often begins with the universe, and finally, perhaps, comes down to some concrete and familiar object or scene that the pupil can understand. Arithmetic has to do with brokerage and partnerships and partial payments and other things that mean nothing to the child. Botany begins with cells and protoplasm and cryptogams. History deals with political and military affairs, and only rarely comes down to physical facts and to those events that express the real lives of the people; and yet political and social affairs are only the results of expressions of the way in which people live. Readers begin with mere literature or with stories of scenes the child will never see. Of course these statements are meant to be only general, as illustrating what is even yet a great fault in educational methods. There are many exceptions, and these are becoming commoner. Surely, the best education is that which begins with the materials at hand. A child knows a stone before it knows the earth. -L. H. BAILEY in "THE NATURE-STUDY IDEA." THE SKUNK Teacher's Story DANGER HOSE who have had experience with this animal, surely are glad that it is small; and the wonder always is, that so little a creature can make such a large impression upon the atmosphere. A fully grown skunk is about two feet long: its body is covered with long, shining, rather coarse hair, and the tail which is carried like a flag in the air, is very large and bushy. In color, the fur is sometimes entirely black, but most often has a white patch on the back of the neck, with two stripes extending down the back and along the sides to the tail; the face, also, has a white stripe. The skunk has a long head and a rather pointed snout; its front legs. are very much shorter than its hind legs, which gives it a very peculiar gait. Its forefeet are armed with long, strong claws, with which it digs its burrow, which is usually made in light soil. It also often makes its home in some crevice in rocks, or even takes possession of an abandoned woodchuck's hole; or trusting to its immunity from danger, makes its home under the barn. In the fall, it becomes very fat, and during the early part of winter, hibernates within its den; it comes out during the thaws of winter and early spring. The young skunks appear in May; they are born in an enlarged portion of the burrow, where a nice bed of grass and leaves is made for them; the skunk is scrupulously neat about its own nest. The young skunks are very active, and interesting to watch, when playing together like kittens. The skunk belongs to the same family as the mink and weasel, which also give off a disagreeable odor when angry. The fetid material which is the skunk's defence, is contained in two capsules under the root of the tail. These little capsules are not larger than peas, and the quantity of liquid forced from them in a discharge is scarcely more than a large drop; yet it will permeate the atmosphere with its odor for a distance of a mile. The fact that this discharge is so disagreeable to all other animals, has had a retarding influence upon. the skunk's intelligence. It has not been obliged to rely upon its cunning to escape its enemies, and has therefore never developed either fear or cleverness. It marches abroad without haste, confident that every creature which sees it will give it plenty of room. It is a night prowler, although it is not averse to a daytime promenade. The white upon its fur gives warning at night, that here is an animal which had best be left alone. This immunity from attack makes the skunk careless in learning Photo by Verne Mortor The skunk. wisdom from experience; it never learns to avoid a trap or a railway or trolley track. The skunk's food consists largely of insects, mice, snakes and other small animals. It also destroys the eggs and young of birds which nest upon the ground. It uses its strong forepaws in securing its prey. Dr. Merriam, who made pets of young skunks after removing their scent capsules, found them very interesting. He says of one which was named "Meph": "We used to walk through the woods. to a large meadow that abounded in grasshoppers. Here, Meph would fairly revel in his favorite food, and it was rich sport to watch his When a grasshopper jumped, he jumped, and I have seen him with as many as three in his mouth and two under his fore-paws at the same time.' manœuvres. The only injury which the skunk is likely to do to the farmers, is the raiding of the hens' nests, and this can be obviated by properly housing the poultry. On the other hand, the skunk is of great use in destroying injurious insects and mice. Often when skunks burrow beneath barns, they completely rid the place of mice. Skunk fur is very valuable and is sold under the name of Alaskan sable. The skunk takes short steps, and goes so slowly that it makes a double track, the imprints being very close together. The foot makes a longer track than that of the cat, as the skunk is plantigrade; that is, it walks upon its palms and heels as well as its toes. Skunk tracks.

LESSON LX THE SKUNK Leading thought-The skunk has depended so long upon protecting itself from its enemies by its disagreeable odor, that it has become stupid in this respect, and seems never to be able to learn to keep off of railroad tracks. It is a very beneficial animal to the farmer because its food consists so largely of injurious insects and rodents. Method-The questions should be given the pupils and they should answer them from personal observations or inquiries. Where Observations-1. How large is a skunk? Describe its fur. does the black and white occur in the fur? Of what use is the white to the skunk? Is the fur valuable? What is its commercial name? 2. What is the shape of the skunk's head? The general shape of the body? The tail? Are the front legs longer or shorter than the hind legs? Describe the front feet. For what are they used? Where and how does the skunk make its nest? Does it sleep like a woodchuck during the winter? What is its food? How does it catch its prey? Does it hunt for its food during the day or the night? Does 3. |
