“This will keep it open,” said he.

“Yes, I think it will,” said Rollo. “But put it up close to the iron wedge.”

“No,” said the boy; “for then I can’t knock the iron wedge out.”

So the boy put the large wooden wedge in, at a little distance from the iron one, and drove it in rather gently with the beetle. This opened the cleft a little more, so that the iron wedge came out pretty easily.

“I don’t see what makes the sides of the logs draw together so hard,” said Rollo.

“O, they can’t help it,” said the boy.

“That is no reason,” rejoined Rollo. “I should think that, after the log is once split open, it would stay so. If I split a piece of wood in two with my knife, the pieces don’t try to come together again.”

So Rollo began to examine the log, and to look into the cracks, to see if he could find out what it was that made the parts draw together so hard as to crush the walnut. Presently, he observed that the log was not split open from end to end. The crack commenced at one end, and extended nearly towards the other, but not quite; so that at this other end the log was solid and whole, just as it always had been. So Rollo perceived that the two halves being joined and held together firmly here, they could only be separated at the other end by the wedge springing them open, and, of course, by their elasticity they tended to spring together again. Then besides, he saw, by looking into the crack, a great number of splinters, large and small, which extended obliquely from one side to the other, and bound the two sides strongly towards each other.

By this time the boy had got the wedge knocked out.

“It is strange,” said Rollo, “that such a small wedge will split such a tough and solid log.”

“O, not very strange,” said the boy. “You see,” he continued, taking up the wedge, and pointing to the several parts as he explained them, “you see here at this part, where it enters the wood it is sharp, and the sides spread out each way, so that, when I drive it in, they force the wood apart.”

“Why don’t they have the back of the wedge wider still? and then it would force the wood open farther; and then you would not have to put in a wooden wedge afterwards,—so,” he added, making a sign with his fingers. He put the tips of his fingers together, and then separated his hands, so as to represent a very blunt-shaped wedge.

“Then it would not drive in so easily,” answered the boy. “Perhaps I could not drive it in at all, if it was so blunt.”

“They might have the wedge longer then,” said Rollo, “and then it would be just as tapering, and yet it would be a great deal broader at the back, because the back would be farther off.”

“That would make the wedge a great deal too heavy. It would not drive.”

“Why, yes, it would,” said Rollo.

“No, it would not,” said the boy. “It would be just like a shoemaker’s lap-stone; pounding it would hardly move it.”

Rollo did not understand what the boy meant by what he said about the shoemaker’s lap-stone; so he paused a moment, and presently he said,

“I don’t think it would make any difference, if it was heavy. And, besides, it might be made of wood, and that wouldn’t be heavy.”

“O, wood wouldn’t do,” said the boy.

Now it happened that while they had been talking, the boy had gone on driving in his wooden wedge into the cleft that the iron one had made, and it had been gradually splitting the log open more and more. So that just as the boy was saying that “a wooden wedge wouldn’t do,” Rollo was actually seeing with his own eyes that it would do; for at that moment the boy gave the last blow, and the halves of the log came apart and fell over, one to one side, and the other to the other.

“Why, there,” said Rollo, “you have split the log open with a wooden wedge.”

“O, that is because I had an iron one in first,” said the boy.

“What difference does that make?” said Rollo.

“A great deal of difference,” said the boy.

“But what difference?” persisted Rollo.

“I don’t know exactly what difference,” said the boy; “only I know you can’t do any thing with a wooden wedge until you have first opened a seam with an iron one.”

Rollo was confident that it could not possibly make any difference whether a wooden wedge was used first or last. The boy was sure that it did, though he could not tell why. Finally, they determined to try it; so the boy struck his axe into the end of the next log, and then attempted to drive in his wooden wedge. But he did not succeed at all. The wedge would not stay. Rollo told him that he did not strike hard enough. Then he struck harder, but it did no good. The wedge dropped out the moment he let go of it, and on taking it up, they found that the edge of it was bruised and battered; so that even Rollo gave up all hopes of making it enter.

“Ah!” said the boy, taking up the wedge, and looking at it, “now I know what the reason is. It is the edge.”

“Where?” said Rollo. “Let me see.”

“Why, when there is no crack,” said the boy, “you see the edge of the wedge comes against the solid wood, and when I drive, it only bruises and batters it; but the iron is hard, and goes in. But then, when a crack is made, the wedge can go in easily; for the edge does not touch; then only the sides rub against the wood.”

“How?” said Rollo. “I don’t understand.”

“I’ll show you in a minute,” said the boy. So he took the iron wedge, and went to work driving it into the log. It soon began to make a crack, which ran along the log, and opened wider and wider. When, at length, it was pretty wide, he put the wooden wedge in, and he showed Rollo that the edge of the wedge did not now have to force its way, but went easily into the crack, and only the sides came in contact with the two parts of the log which it was separating.

“That’s curious,” said Rollo.

“Yes,” said the boy.

“I wish I had a little beetle and wedge,” said Rollo. “I have got a hammer. That would do for a beetle, if I only had a wedge.”

“O, a hammer won’t do,” said the boy.

“Why not? Would not an axe do as well as a beetle?”

“No,” said the boy, “it would spoil the axe and the wedge too.”

“How?” asked Rollo.

“Why, it would bruise it all up,—hard iron knocking against the hard iron.”

“Would it?” said Rollo.

“Yes,” replied the farmer’s boy; “it would spoil the head of the axe, and the head of the wedge too.”

“Is that the reason why they make a wooden beetle?”

“Yes,” said the boy; “and they put iron rings around the ends to keep the wood from being bruised and battered.”

“O, I wish I had a little beetle and wedge!” said Rollo.

“Perhaps you might make one.”

“O, I could not make an iron wedge—nor the beetle rings.”

“No, but you might make wedges of wood,—pretty hard wood; that would do to split up pieces of pine boards, and then you would not need any rings to your beetle.”

“Jonas can help me,” said Rollo.

“Yes,” said the boy; “Jonas will know all about it.”

So Rollo set out to go home, full of the idea of making a wooden beetle and wedge, so as to split up pieces of boards. He determined, in case he should succeed, to make a smaller one still for Thanny.

THE LITTLE BEETLE AND WEDGE

When Rollo got home, he looked about for Jonas every where, but could not find him. He went around the house and yard, calling “Jonas! Jonas!” very loud. Presently Nathan came out to the door, and told him that his mother wanted to see him. So Rollo went in to his mother.

“You ought not to make such a noise,” said she, “calling Jonas. You disturb us all.”

“But, mother,” said he, “I want to find him very much.”

“No doubt,” said his mother; “but you must find him with your eyes, not with your tongue.”

“Why, mother,” said Rollo, laughing, “what do you mean by that?”

“Boys very generally have a habit of trying to find people with their tongues, that is, by calling them; but it is a very bad habit. You see,” she continued, “there are five or six persons now in and about the house, and if you go around calling out for Jonas, you disturb us all; but if you go about quietly, and look for him, you do not disturb any body.”

“But then it is not so easy to find him by looking for him,” said Rollo.

“Why not?” asked his mother.

“Because,” said Rollo, “I can call out for him, in a moment, in the yard, and then if he is any where within hearing, he answers; and so I know where he is. But it would take me some time to go to all the places that are within hearing.”

“True,” said his mother, “I see it is more trouble to find any body with your eyes, than with your voice; but then it is so much pleasanter for all the rest of us, that you must submit to it.”

So Rollo went away again to look for Jonas. He inquired of Dorothy in the kitchen, and she told him that she saw Jonas going out towards the barn a few minutes before. So Rollo went off in pursuit of him.

He found him at work in a little back room in the barn, looking over some harnesses.

“What are you doing, Jonas?” said Rollo.

“I am overhauling these harnesses, to get them all ready for winter.”

“For winter?” said Rollo.

“Yes,” replied Jonas; “they are sleigh-harnesses.”

“Well, Jonas,” said Rollo, “I wanted to see you about a beetle and wedge. Do you think you could help me about making a little beetle and wedge?”

“I can help you by my advice,” said Jonas.

“O, but I want you to help me make them.”

Then Jonas asked Rollo what made him think of a beetle and wedge; and Rollo told him of the conversation he had held with the farmer’s boy. Then Jonas talked a long time about it, giving him particular advice and direction about the plan, though he said he could not himself go and help him then, for he could not leave his harnesses.

The advice which Jonas gave him was, substantially, this:—

“The boy was right in what he said about the necessity of having iron wedges, to split up large logs of hard wood; but you had better have short pieces of pine boards for your logs, and then wedges of hard wood will do instead of iron; for hard wood is so much more solid than pine, that I think wedges of it will answer very well. There are some pieces of walnut under the bench, which will do finely, and I will give you one of them.”

“I’ll go, now, and get it,” said Rollo.

“No,” said Jonas, “not yet; let me tell you about making the beetle.”

So Rollo stood in the door way, waiting to hear what Jonas had to say about the beetle, but evidently quite impatient to go.

“If you make your wedges of hard wood, it will not be necessary to have iron rings to your beetle, because it will not get battered much, in driving wooden wedges. Now you must go to the wood pile, and look out a piece of round wood, about as large round as my arm, and bore a hole in it.”

“A hole in it!” said Rollo.

“Yes, a small auger hole, to put the handle into. Then you must put the wood into the saw-horse, and saw off the ends, at a little distance from the hole, so that, when the handle is put in, it will be like a mallet.”

“A mallet!” said Rollo. “But I wanted a beetle.”

“Well, a mallet is a small beetle, without rings.”

“Is it?” said Rollo, thoughtfully.

“Yes,” replied Jonas; “and if you work slowly and carefully, I think you can make a pretty good one yourself.”

Rollo thought so too, and away he ran to make the experiment. Under the great work bench, he found, among a quantity of boards and bits of wood, a number of long bars of walnut, which Jonas had split out from the wood pile to keep for handles. He took one of these, and carried it off to the shed, to look for the saw and the hatchet.

The first thing was, as he supposed, to saw off a piece of the wood just long enough for a wedge. But in this he was mistaken. In doing any piece of work of this kind, it is always very important to consider which part it is best to do first. Rollo did not think of this, and so he marked off a piece of the walnut wood about long enough for a wedge, and then sawed it off.

“Now,” said he, “I must make the sides smooth, and sharpen it.”

So he took the piece of wood in his hand, and put one end of it down upon a large log of wood, and then attempted to smooth and sharpen it, as he had seen Jonas sharpen a stake. But he could not succeed very well. The wood was very hard, and he could not cut it. Then it was so short that it was almost impossible to hold it. At almost every blow of the hatchet it slipped out of his hand; and then, besides, he was very much afraid of cutting his fingers; so that, after working laboriously for some time, he came back to Jonas in despair, holding his wedge in his hands, which, however, instead of being properly sharpened, was only rounded off a little at the corners.

“O dear me!” said he to Jonas, as he came up to him with the intended wedge in his hands, “I can’t make a wedge at all. It’s no use to try.” Then he explained to Jonas the difficulties that he had met with.

“True,” said Jonas; “I see. I advise you to give it up.”

“Yes,” said Rollo, “the wood is so hard.”

“O, no,” said Jonas; “that is no great trouble—you could easily manage that.”

“But then I can’t hold it.”

“That is of no consequence either. I could tell you a way to hold it well enough.”

“What is the reason, then, why you think I had better give up?”

“Because you have not patience enough.”

Rollo stood silent and thoughtful as Jonas said this, with his piece of wood in one hand, and his hatchet in the other.

“It takes a great deal of patience to make a thing which we never made before.”
