Chapter 5

"I supposed," said Peter, "that moths and butterflies were just the same, except that moths will fly into the house and burn their wings on the lamps." Peter didn't in the least care about moths and butterflies. He was longing to get to the top of the mountain, but he was too polite to seem impatient.

"They are alike in many ways. You remember, do you not, that the locust has a pair of soft jaws covering over the dark, hard ones? In the moths and butterflies these jaws are different. Each one is long, and has a deep groove on the inner side. These two grooves fit together, and make a slender tube called a proboscis. When flying this long tube is rolled up in a tight coil under the head; alighting, the proboscis is quickly uncoiled and dipped into the throat of the flower, and the sweet nectar sipped from it. See here, Jack, what have you on your fingers?"

"The dust from the butterfly's wings, sir."

"No, not quite dust, or powder, either. That dust is tiny hair and scales. If I had a powerful lens in my pocket I could show you how deeply some of these tiny scales are scalloped, so that they look like a hand with fingers. If you rubbed all the scales off that wing there would be no color left, for the scales are like little sacs, and many of them contain grains of color called pigment--red, yellow, or brown. You have all seen the rainbow of colors on a soap-bubble? Well, the brilliant colors of the wing are made in just the same way as the colors on a bubble: by the light striking the little ridges on the overlapping scales."

"It is not only we who are fearfully and wonderfully made," said Mrs. Reece, "but even the tiniest creatures God has created, and all with a purpose, all with a place."

The guide nodded his head. "The more you study, the more you see how every least thing is part of a great mysterious whole. If you look at a butterfly's wing from which the scales have been rubbed you will see plan and purpose in the placing of even those scales; for the little pits into which the stems of the scale fit are turned all one way, toward the base of the wing."

"They are so beautiful!" exclaimed Betty. "Are they always pretty?"

"That depends," replied the old man, "whether in their caterpillar youth you think them pretty. They have a bad name, then, for being homely, and do a good deal of damage."

"Oh, I hate caterpillars!" cried Hope.

"Fuzzy caterpillars hump so and crawl," said Betty.

"You mean woolly bears?"

"Woolly bears!" exclaimed the children.

"Yes; not Teddy bears. They have to play somehow, so they wiggle for joy, and this takes them along very fast--that is, fast for a caterpillar. Sometimes they spin a long thread by which they take a flying short cut and land--on your back."

Jimmie dropped a tiny twig down Betty's back, which made her scream.

"But they don't harm us," said Ben Gile. "They are so fussy about what they eat for dinner that they wouldn't think of biting even the sweetest little boy or girl. They prefer something far more tender. Ah, you wouldn't like Isabella!" The old man shook his head sadly.

"Isabella! Who is Isabella?" questioned the children.

"Isabella is always in a hurry," said the guide--"always. She is brown in the middle, and black on the head and tail end, Isabella is, and she walks rapidly, as if she had a great deal to do before she could take time to be made over into a tiger-moth. She stops every once in a while to make sure she is on the right road; then she hurries along in a nervous, fidgety way, looking for a nice, comfortable stone under which to have a winter home, for Isabella is in such haste that she could never think of taking time to spin a cocoon."

"But do all caterpillars turn into moths or butterflies?" asked Jack.

"Yes, every one, my son, that lives long enough, just as surely as a boy will turn into a man. The butterfly lays the egg, and after the egg has been quiet for a while out comes a little worm; the worm spins the cocoon, and out of the cocoon comes a perfect moth, or butterfly. It is a wonderful cycle, a wonderful series of changes. Little boys and girls seem to be surrounded with more love and don't change their skins as moths do, but the mystery of life belongs quite as much to the helpless moth as it does to any one of us."

"But is a caterpillar an insect, and is a butterfly an insect?" asked Betty.

"Of course, you goose," said Jimmie; "you don't expect to hatch a duck from a hen's egg, do you?"

But Ben Gile, who was older than Jimmie and decidedly more patient, explained, carefully: "If you look at a caterpillar and a moth you will see that their bodies aren't so unlike, after all. They are made up of rings, and both the moth and the caterpillar have six legs apiece. Most caterpillars have little prop legs, but these aren't real legs and shouldn't be counted. Caterpillars eat and eat and eat; they are such solid little chaps they must need a good many legs, real and false, to keep moving at all. Well, heigho! stretch your own legs, boys! We'll leave the caterpillar where it is, and move on to the top of the mountain, or we'll never be there in time to eat our own supper. One, two, three, march!"

And off they went, talking and laughing and scrambling up the side of the mountain, which swung dark and steep above them.

XII

CAMP-IN-THE-CLOUDS

The camp was reached. Once there, the children found the other two guides in the cabin. The cook-tent was already pitched; the sleeping-tents had been left so that the boys might choose their own locations and help in pitching them. It was a beautiful place--remote, wild, two-thirds up the side of the great mountain.

In front was the famous trout pond, and beyond the little valley made by the pond the crest of the mountain rose higher and higher. Dusk was coming on, and the crisp mountain air was filled with the shadows of the woods; along the mountain summit lay streamers of white cloud. Down, down, down reached the long fingers of cloud, and up, up, up reached the deep shadows, just as if a great hand were closing the world in dusk. Every little sound was as clear in the evening air as the water of the pond was transparent. Small shadows moved about the edge of the pond--deer, they were, said Ben Gile, that had come down to the edge to drink.

"Phew, isn't it cold!" shouted the children, as they ran from one thing to another; "and won't supper taste good!"

Jack, who hadn't on any stout boots like Jimmie's, and whose jacket was threadbare and thin, began to think the sleeping-blankets would feel good when it was time to crawl in. In front of the cabin blazed a big camp-fire, and around this fire supper was served. "Did stewed apricots, soda-biscuits, bacon, eggs, hot cakes, ever taste so good? Will they ever taste so good again? Did hot cakes and syrup ever make the butter fly so fast?" asked Ben Gile.

"And, speaking of the butterfly," he went on, "it's not time to turn in yet, it's too dark to fish or explore, so let me tell you a little more about the butterfly, and if you don't like it you can just imagine it is a hot-cake butterfly."

The children thought this was a great joke. But Peter, who had eaten so much he was almost asleep, didn't hear what Ben Gile said.

"Well," the old man continued, just as if he were beginning where he had left off in the afternoon--"well, the caterpillar eats so much--it eats almost as much as Peter does"--at this Peter opened his eyes good-naturedly--"it eats so much that very soon it grows too big for its skin, so the old skin splits for the growing body, and out comes young caterpillar in a clean, new dress--a very easy way for Mrs. Butterfly to have her babies get new clothes. Don't you think it is, Mrs. Reece?--no hems to stitch, no buttons to sew on, no darning. The only things their mothers ever do for them is to start them with the food they like.

"And such a butterfly this mother is that little she cares whether her children are considered pests or not, because they eat everything green that they like, and eat before they are invited. A long sigh of relief the gardener or farmer draws when the caterpillars lie quiet to pupate. They lie very, very quiet, with wings, antennæ, and legs folded under the body."

"What does pupate mean?" asked Betty, who was poking the fire and listening hard to every word the old man spoke.

"It means just that--to lie quiet and change. They do it in different ways. Some crawl down into the ground and some pull out their silky hairs, and with these and the silk they can spin they make a soft, silken cocoon. Some make over their last skin into a hard covering. The monarch butterfly does this.

"And there is a troublesome creature called the clothes moth--Mrs. Reece can tell you about that--who lays its eggs on anything woollen it can find. After a while a baby clothes moth, a whitish worm, hatches out. Then this little fellow eats the fibres of the wool, and finally spins a cocoon out of these fibres and its own silk.

"Some caterpillars are leaf-rollers--that is, when they pupate they roll over the corners of a leaf, make themselves a neat hammock, and there lie quite still in a cool and comfortable place to sleep."

Poor Peter had tumbled over, his head on Mrs. Reece's lap. Betty and Hope, wide awake, were thinking just as much of the wonderful tent in which they were to sleep as of the butterflies and moths. They were wide awake enough to point their fingers at sleepy Peter.

"I think there is one kind of moth," said Mrs. Reece, stroking Peter's silky hair, "that spins something almost as soft as this."

"Softer," affirmed Ben Gile; "and that is the silk-worm."

"Does the caterpillar make the silk our dresses are made from?" asked Betty.

"Yes, indeed. The mother moth is a creamy-white. She lays several hundred eggs; from each of these eggs comes a little worm. These little worms have been cared for so long by men that they don't know how to take care of themselves any more.

"They like to eat the leaves of the mulberry-tree. If these leaves are not to be found they will sometimes eat lettuce. For forty-five days they eat as fast as they can, which is a good deal faster than greedy children can eat.

"Every ten days or so they cast aside their old skin and come out in a new one. After the last moulting of the skin the worm begins to spin a cocoon about itself. At first the cocoon is not very smooth, but in a while the worm gets well started and spins the rest of it with one long, silky thread."

"Isn't that wonderful!" exclaimed one of the guides. "I suppose that silk is finer than the finest trout-line."

"A hundred times finer," answered Ben. "Usually it is three hundred yards long. Before the pupa has a chance to make its way out, and so destroy the long, silken thread, the man who has taken such care of the worm drops the cocoon into boiling water, which kills the pupa at once. Then the precious silk thread is carefully unwound on to little spools, and is ready to be made into thread or spun into silk.

"And now, children, it's time for you to spin your dreams. Shake up Peter, and we'll get ready for the night. Too bad to leave this fire, but we can have one as often as we want."

The boys slept like tops, but there were two little girls who lay rather wide awake most of the night, listening to the strangest grunting sounds in the world.

XIII

STORM-BOUND

After two glorious days of exploring--"exploricating," the guides called it--the children went to bed early, expecting to make an early start to hunt partridge. They were so tired from their good times that for two or three hours they slept like tops.

But in front of the cabin Ben Gile and Mrs. Reece and the other guides were looking at the night sky anxiously. The lightning flashed more and more vividly, black clouds were coming nearer and nearer. What was a distant rumble soon became a near-by, long undertow of ominous sound. Nearer and nearer it came, until every flash was followed by a sound like ripping.

Mrs. Reece was very uneasy, for she did not like to have the children in the tents alone. But soon Betty and Hope came scampering through the dark to the cabin. They were surprised to see the older people up. Before long the boys also came to the cabin rubbing their eyes, yawning, and pretending not to care whether there was to be a cyclone or a cloud-burst.

For a while all sat waiting for the storm to break. When it did break, what torrents of rain and wind descended! How the trees groaned and cracked! How the rain roared upon the shingled roof, and how the wind howled through the mountain valley!

"Well," said Ben Gile, "let's have a fire in the fireplace, then we can have a crackle of our own." He had noticed how nervous Mrs. Reece grew, and that the little girls were watching her. He could not help thinking that it was foolish, even wicked, to waste strength in fear of something which no one of them could stop. "Build a fire, boys." And build a fire they did--a royal good blaze. "Now throw on some of those pine-cones you children gathered." There was a flare in the cabin almost as bright as the incessant flare of the lightning outside. "I'll tell you what we'll do," he continued, "we will have a midnight spread. We will have some of Tom's famous flapjacks. Mrs. Reece, don't you want to make molasses candy, and then the children can pull it."

The storm was forgotten by the children as, with many squeals of glee, they rushed into this midnight frolic.

"And now, Ben," said Tom, the guide, "I've just found something; I have it in my hand. I propose, Ben, while the rest of us work, that you make one of your stories out of it, and tell us all about it."

Tom opened his hand, and the children crowded around to see. There was a shout of laughter.

"Why, that's only a dead June-bug!"

"Who wants to know about a June-bug?" exclaimed Jimmie, much to the discomfiture of the guide, who knew a great deal about moose and deer and bears and beavers, even if he didn't know much about a June-bug. The guides had profound respect for the schoolmaster, Ben Gile, who was really too wise and kind to laugh at another's ignorance. But this is another story, and Jimmie learned better in the years to come.

"You're right, Tom," said Ben, "to want to know. Sometimes it's about these commonest things folks know the least. When I was a boy it was always so with me. There are several facts about a June-bug that are interesting. First, it is not a bug at all; and, second, it comes in May and not in June. It is really a May-beetle, and a great, clumsy, buzzing, blundering fellow it is, as careless about its appearance as it is about the way it enters a room. You know the old adage, 'Haste makes waste'? Perhaps it's the haste that makes the June-bug's untidiness. Beetles have hard wing covers--see these little shell-like casings?--to cover the more delicate wings underneath. The June-bug has wing covers, too, but it never keeps its best wings tucked in. They are always hanging out in a crumpled way. These bugs eat the leaves of the trees, and their children, little, fat, white grubs with horny heads, nibble, as they crawl around under the surface of the earth, the tender roots of the grass and the strawberry plants."

"Why, Ben, you've told me more already," said Tom, "than any dullard like me could ever learn from a book. To think it's a beetle! But I might have known from looking at it. Are all the beetles harmful?"

"Most of them are pests, and do a good deal of damage. Its cousin, rose-beetle, is pretty, her body covered with soft, yellow hairs, and she has rose-colored legs. But handsome is as handsome does, and rose-beetle causes more damage than her clumsy cousin, for Rose feeds on rose-bushes as well as on fruit trees. Indeed, almost everything that comes to her mill is grist. She's as bad--and worse--than the elm-beetle."

By this time the cooking molasses smelled so good, the cabin fire roared so pleasantly, and the smell of the flapjacks Adam was frying was so appetizing, that the children had quite forgotten the storm outside, and were having one of the jolliest frolics of their lives--one they never forgot.

"Tell us something more, sir," urged Jack, "about the beetles."

"There is one comical fellow who makes me think of Peter. In the books it is called a click-beetle, but it is also called a skip-jack because of the somersaults it can turn. On the under side of its thorax is a spine resting on the edge of a hole. This funny beetle, by pushing the spine down over the hole and then letting it go, throws itself up in the air with a sharp click."

"Oh, I know them," called Hope, "for I have seen them doing it, but I never knew how they did it!"

"And now," said Master All-Wise, very soberly, "after I tell you that the children of the click-beetle are called wire-worms, and that they eat and kill the roots of plants, I want to tell you about a beetle no one of you has ever seen--a most extraordinary beetle."

All were attention at once.

"Many years ago there lived away out in California a little, round, brownish, striped beetle, which crawled about and ate heartily of a plant called the sand-bur. One day one of the family happened to wander up to a nice, juicy potato plant. After eating its fill it probably looked up some of its brothers and sisters, and told them about these good plants growing in the fields. With one accord they left the sand-burs and began to eat the potato plant. Farther and farther they wandered, until thousands of them reached the eastern part of our country, eating the potato plants wherever they found them on the way. Now, these beetles are to be seen everywhere in our country, spoiling crop after crop."

By this time Jack's eager face was smiling, and he was looking questioningly at Ben Gile.

"What kind of a beetle do you suppose it was?" asked the old man.

Nobody knew. At last Jack ventured, "Was it a potato-bug, sir?"

"Yes."

"Oh, of course!" shouted the children. "Why didn't we think of that? But you said we had never seen it."

"So I did," said the guide, "and I don't believe there is one child here who has ever carefully watched the potato-bug. And there's the carpet-beetle, whose babies eat carpets unless your mother tempts them with pieces of red flannel. And there's the searcher-beetle, with its pretty green or violet wing covers, who is always on the search for caterpillars. And there's the fire-fly, which is a soft-bodied beetle.

"And there's the very useful little beetle we call the ladybug, which is not a bug, but a beetle. The ladybug is a great help to men who own fruit orchards in the West. All over the country are to be found little bugs called scale insects. These scales are very bad for trees, because with their long, slender beaks the scales pump out the sap. Sometimes they are so thick on the branch that they coat it entirely. You remember that I told you that one of these troublesome scales is the cottony-cushion scale, and that one day it was discovered that a lady-beetle from Australia liked these scales very much. So a great many of them were taken to California to eat the scales. The ladybugs eat little green aphids, too, and often Mrs. Ladybug will lay her eggs right in the midst of a family of aphids; and then the larvæ are surrounded by a hearty lunch when they come out of the egg. They eat the aphids, the scales, and sometimes the eggs of other insects."

"Time, Ben," said Adam, "to have the flapjacks. I guess the storm must be blowing over."

All drew up to the cabin table, and ate as heartily as if they were eating dinner. It really looked as if the children had had no supper.

"In about half an hour," said Tom, "the storm will be over. Aren't there any beetles that live in the water, Ben?"

"Oh yes; you can see them any day if you go by a brook. The diving-beetles are skimming about, rowing themselves along with their flattened hind legs. Every few minutes they come to the surface and lift their wings to get a little air under them, then down they go into the brook. They are very hungry beetles, eating other insects which they find in the water. The boldest often try to take a bite out of a fish. Just think of calling a baby beetle a water-tiger! Well, these babies are as savage and ferocious to the little creatures living about them in the water as a big tiger would be to us, if we should happen to meet one.

"I like best the whirligig-beetles, they are such frisky fellows, always having a good time, frolicking about with dozens of other little whirligigs. They are bluish-black and shiny, and if you look carefully you will see a little bubble at the tip of every tail. This little bubble is held there by tiny hairs, and because whirligig has it, it can breathe while it stays under the water. From time to time it comes to the surface to get a new bubble, then is off again for another race or game of tag with its friends, and at the same time to snap up a few water creatures for dinner. It looks as though it had four eyes, but it has not, just two, divided into upper and lower halves. The upper halves look up through the water and the lower ones down at the bottom of the brooks. So, you see, insects must step lively if they want to keep out of its clutches.

"The babies of some beetles, instead of liking nice, clean food, prefer dead animals. The mother and father hunt around until they find a dead mouse or bird; then they begin to dig away the earth under the mouse or bird and around it. Finally the poor dead thing is in a deep hole; then Mrs. Burying-beetle lays her eggs on it, and together they cover it up with earth. When the grubs hatch they find plenty to eat, and are soon big burying-beetles, like their mothers and fathers.

"Did you ever wonder how the little fat worms get inside of chestnuts and acorns? A beetle called a weevil is the creature which puts the fat worms there. Mrs. Weevil has a long, slender, curved beak. She crawls up on to the side of a chestnut, bores a hole in the side, then lays an egg deep down in it. After a while the egg hatches and a tiny grub begins to feed on the nut. Fatter and fatter it gets; sometimes it lies in the nut all winter, but more often it crawls out and buries itself in the ground while it grows into a weevil.

"Some day, as you are walking along a sunny road in the country, you may meet a blister-beetle. It is a pretty, bluish-green color, and when you pick it up you will see drops of oil oozing out of its joints. The dried bodies will raise a blister on the skin, and that is the reason we call such beetles blister-beetles. There is a queer blister-beetle who lays her eggs near bees' nests. The baby beetles then wait for a bee to come along. They fasten themselves to the hairs on the bee's body. When the bee goes to its nest to put in the honey the young beetle manages to get into a honey-cell with the egg. Mrs. Bee does not see that anything is amiss, seals up the cell, and flies away for another load. The larva first eats the egg of Mrs. Bee, then it changes into a clumsy kind of a fellow, floats in the honey, and eats all it can so that it will quickly become a grown-up.
