Rollo's Experiments

“But what do you suppose is the reason,” said Rollo, “that we must make it point to the North Star more than to any other?”

“I don’t know,” said Jonas, “unless it is because the North Star is the only one that keeps always in the same place. The rest move round and round every day. Those that are far enough from the North Star to go down below the horizon, rise and set; and those that are not far enough, go round and round in circles, in the open sky. But the North Star keeps still.”

“Does it?” said Rollo, turning around, and looking up to the part of the heavens where he had seen the star the evening before.

“Yes,” said Jonas; “and the reason why we cannot see it now, is the bright daylight. It is up there now, just where it was last night.”

“And the Dipper, too?” said Rollo.

“Yes, and the Dipper, too; only that has moved half round, I suppose, and is now away up above the North Star.”

“I wish I could see it,” said Rollo. And he looked as steadily and intently into the clear blue sky, as he could; but he could not possibly see the least sign of a star.

However, the sun shone bright, and it cast a strong shadow from the stakes which they had driven into the ground. Jonas soon went away to his work, and left Rollo to mark the hours by means of the clock.

So Rollo had to go into the house very often to see what time it was; and at last his father, who was sitting there at his writing, asked him what made him want to see the clock so much. Rollo told him the reason. So his father put down his pen, and came out to see the dial.

When he saw the two stakes, with their lower ends driven into the ground, and the upper ends nailed firmly together, he looked at them with a smile, but did not say any thing.

“Will that do?” said Rollo, looking up very eagerly into his father’s face.

His father did not answer, but continued to examine the work on all sides, with a countenance expressive of curiosity and pleasure.

“It points to the North Star, exactly,” added Rollo. “Jonas sighted it.”

“Yes,” said his father; “I think that will do; you have got quite a respectable gnomon.”

“Gnomon?” said Rollo.

“Yes,” said his father; “we call such a thing a gnomon. In common dials, they are made of brass; but I don’t see why this won’t do very well. It is rather a large gnomon.”

“Is it?” said Rollo.

“Yes,” said his father, “I think it is the biggest gnomon I ever saw.

“But how are you going to mark the hour lines, Rollo?” asked his father.

“Why, we are going to drive little stakes down into the ground.”

“’Seems to me that you can contrive some better plan than that,” said his father.

“Why?” said Rollo. “Is not that a good plan?”

“Not very good,” he replied; “because you cannot be exact in driving down stakes. The beauty of a dial is its exactness. I should think that you would do better to put a board down upon the ground, and mark your lines upon that.”

“O, the board would get knocked about,” said Rollo.

“I dare say that Jonas would contrive some way to keep it steady.”

“But he says he can’t do any thing more about the dial to-day, for he must attend to his work.”

“Let me see—he is putting the harnesses in order, I believe.”

“Yes, sir,” said Rollo.

“Well, you may tell him that after he has done the harness that he is at work upon now, he may finish his dial.”

Then Rollo’s father went into the house, and away went Rollo in pursuit of Jonas.

Jonas liked the plan of putting a board down very much, and in a short time he went to work to do it. He planed out a board of the right length, and then put it down upon the ground, under and between the two stakes, but nearest to the upright one. They placed it across at right angles to the line between the stakes, and of course, as the stakes were in a north and south line, the board was in an east and west line, and so the shadows were cast exactly across it.

The board being planed smooth, the edge of the shadow could be seen much more distinctly upon it, than upon the ground; so Jonas was satisfied that it would be a great deal better to draw the hour lines upon the board. After having determined upon the place where it was to go, he took it up again, and then drove down two strong but short stakes, sawed off square at the top, into the ground, one on each side; so that they should come under the two ends of the board. Then he laid the board down again upon the stakes, and nailed the ends of the board to them. The stakes had been driven in until they were just level with the surface of the ground, and so the board seemed to be lying along upon the ground too, though it was, in fact, fastened securely to the short stakes. Then the boys marked the hour lines upon the board with some black paint; and thus they had a very respectable dial. When the sun shone, Rollo could tell what o’clock it was near enough for all his purposes.

THE BEE-HIVE

One of the drollest of all of Rollo’s experiments was his plan for getting a bee-hive.

One day, he was in the garden with a playmate of his, named Henry, who lived not very far from his father’s house.

In the back part of the garden were some tall hollyhocks growing. They were in full flower. Hollyhocks are very tall. They grow up in a straight stem, as high as a man’s head, with leaves and flowers from top to bottom.

The flowers are large, and shaped somewhat like a cup, or rather a wine-glass, and bees often go into them to get honey.

Now it happened that as Rollo and Henry were sauntering about, near these hollyhocks, Rollo happened to see a bee in one of the flowers, loading himself up with wax or honey. The flower, that the bee was in, was just about as high as Rollo’s head.

“O, there’s a bee!” said Rollo; “let’s catch him.”

“Catch him!” said Henry. “If you do, you’ll catch a sting, I rather think.”

“No,” said Rollo, “I can catch him without getting stung.”

“How?” said Henry.

“I will show you,” said Rollo.

So saying, Rollo approached the hollyhocks, and put both his hands up slowly to the flower which the bee was in. He then very carefully gathered together the edges of the flower, so as to enclose and imprison the bee. He then gently broke off the stem of the flower, and held it up to Henry’s ear, to let him hear the bee buzz within.

“Now,” said Rollo, “I wish I had a little bee-hive. I would put him in, and perhaps he would make some honey in there.”

“Do you think he would?” said Henry.

“Yes,” replied Rollo, “I have no doubt he would; bees always make honey in bee-hives.”

“Haven’t you got some box that will do?” said Henry.

“I don’t know,” said Rollo; “let us go along towards the barn, and see if we can’t find one. I suppose it is no matter what the shape of it is,” he added, “if it is only a box, with a small hole for the bees to go in and out.”

“But you haven’t got but one bee,” said Henry, as they walked along towards the barn.
