Part 2

"And what do you expect to do with yourself all that time?" said she.

"O, I don't know," said Rollo. "Perhaps I shall help Jonas, a part of the time, about his work."

"That will be a very good plan for a part of the time," said his mother; "though he is doing pretty hard work just now."

"What is he doing?"

"He is digging a little canal in the marsh, beyond the brook, to drain off the water."

"O, I can dig," said Rollo, "and I mean to go now and help him."

This was about the middle of the forenoon; and Rollo, taking a piece of bread for a luncheon, and a little tin dipper, to get some water with, to drink, out of the brook, walked along towards the great gate which led to the lane behind his father's house. It was a pleasant, green lane, and there were rows of raspberry-bushes on each side of it, along by the fences. Some years before, there had been no raspberries near the house; but one autumn, when Jonas had a good deal of ploughing to do down the lane, he ploughed up the ground by the fences in this lane, making one furrow every time he went up and down to his other work. Then in the spring he ploughed it again, and by this time the turf had rotted, and so the land had become mellow. Then Jonas went away with the wagon, one afternoon, about two miles, to a place where the raspberries were very abundant, and dug up a large number of them, and set them out along this lane, on both sides of it; and so, in a year or two, there was a great abundance of raspberries very near the house.

Rollo stopped to eat some raspberries as he walked along. He thought they would do exceedingly well with his bread, to give a little variety to his luncheon. After he had eaten as many as he wanted, he thought he would gather his dipper full for Jonas, as he was busy at work, and could not have time to gather any for himself.

He got his dipper full very quick, for the raspberries were thick and large. He thought it was an excellent plan for Jonas to plant the raspberry-bushes there; but then he thought it was a great deal of trouble to bring them all from so great a distance.

"I wonder," said he to himself, as he sat upon a log, thinking of the subject, "why it would not have been just as well to plant raspberries themselves, instead of setting out the bushes. The raspberries must be the seeds. I mean to take some of these big ones, and try. I dare say they'll grow."

But then he reflected that the spring was planting time, and he knew very well that raspberries would not keep till spring; and so he determined to ask Jonas about it. He accordingly rose up from the log, and walked along, carrying his dipper, very carefully, in his hand.

At length, he reached the brook. There was a rude bridge over it made of two logs, placed side by side, and short boards nailed across them for a foot-way. It was only wide enough for persons to walk across. The cattle and teams always went across through the water, at a shallow place, just below the bridge.

Rollo lay down upon the bridge, and looked into the water. There were some skippers and some whirlabouts upon the water. The skippers were long-legged insects, shaped somewhat like a cricket; and they stood tiptoe upon the surface of the water. Rollo wondered how they could keep up. Their feet did not sink into the water at all, and every now and then they would give a sort of leap, and away they would shoot over the surface, as if it had been ice. Rollo reached his hand down and tried to catch one, to examine his feet; but he could not succeed. They were too nimble for him. He thought that, if he could only catch one, and have an opportunity to examine his feet, he could see how it was that he could stand so upon the water. Rollo was considering whether it was possible or not, that Jonas might make something, like the skippers' feet, for him, to put upon his feet, so that he might walk on the water, when suddenly he heard a bubbling sound in the brook, near the shore. He looked there, and saw some bubbles of air coming up out of the bottom, and rising to the top of the water. He thought this was very singular. It was not strange that the air should come up through the water to the top, for air is much lighter than water; the wonder was, how the air could ever get down there.

From wondering at this extraordinary phenomenon, Rollo began to wonder at another quite different question; that is, where all the water in the brook could come from. He looked at a little cascade just above the bridge, where the water rushed through a narrow place between two rocks, and watched it a few minutes, wondering that it should continue running so all the time, forever; and surprised also that he had never wondered at it before.

He looked into the clear, transparent current, which poured steadily down between the rocks, and said to himself,

"Strange! There it runs and runs, all the time--all day, and all night; all summer, and all winter; all this year, and all last year, and every year. Where can all the water come from?"

Then he thought that he should like to follow the brook up, and find where it came from; but he concluded that it must be a great way to go, through bushes, and rocks, and marshes; and he saw at once that the expedition was out of the question for him.

Just then he heard another gurgling in the water near him, and, looking down, he saw more bubbles coming up to the surface, very near where they had come up before. Rollo thought he would get a stick, and see if he could not poke up the mud, and find out what there was down there, to make such a bubbling. He thought that perhaps it might be some sort of animal blowing.

He went off of the bridge, therefore, and began to look about for a stick. He had just found one, when all at once he heard a noise in the bushes. He looked up suddenly, not knowing what was coming, but in a moment saw Jonas walking along towards him.

"Ah, Jonas," said Rollo, "are you going home?"

"Yes," said Jonas, "unless you will go for me."

"Well," said Rollo, "what do you want me to get?"

"I want some fire, to burn up some brush. You can bring out the lantern."

"Very well," said Rollo, "I will go; only I wish you would tell me where these bubbles come from out of the bottom of the brook."

"What bubbles?" said Jonas.

So Rollo took his stick, and pushed the end of it down into the mud, and that made more bubbles come up.

"They are bubbles of air," said Jonas.

"But how comes the air down there," said Rollo, "under the water?"
