Part 27

He was as much of a plaything for the soldiers as he had been for the Indians. They laughed at his pranks, as they might have done if he had been a monkey. He passed from one squad of soldiers to another. They fed him on hard-tack, and shared their blankets with him. He was the pet and plaything of them all. But after a while the Indians were driven away from the settlements, and the soldiers were ordered to the South, for it was in the time of the Civil War.

The regiment that Peter happened to be with got on a steamboat, and Peter went aboard with them. The soldiers knew that if Peter should be taken to the South, he would be farther than ever away from his friends. So the soldiers made up their minds to put him ashore at Winona. It was the last place at which he would find Norwegian people. To put such a little fellow ashore in a large and busy place like this was a hard thing to do. Peter was hardly more than a baby, and he could not speak English. He stood about as much chance of starving to death here as he had in the Indian camp.

When the boat landed at Winona, the soldiers gave some money to one of the hotel porters, and told him to give the child something to eat, and send him out into the country where there were Norwegian people. But as soon as Peter had eaten the dinner they gave him at the hotel, he slipped away, and went back to the river. He expected to find his friends, the soldiers, waiting for him; but the boat had gone. Peter was now in a strange city, without friends. Not without friends, either, for his sisters were in this same city. But he did not think any more of getting to his mother or his sisters. He was only thinking of the soldiers who had been so kind to him.

When the next boat came down the river, Peter Petersen, in his little blue uniform, marched aboard. He thought he might overtake the soldiers, but the boatmen put him ashore again. He stood gazing after the boat, not knowing what to do or where to go.

There stood on the bank that day a Norwegian. He was a guest at the Norwegian hotel in the town. He heard Peter say something in his own language, and he thought the boy must be a son of the man who kept the hotel. So he said to him in Norwegian, "Let's go home."

It had been a long time since Peter had heard his own language spoken. Nobody had said anything to him about home since he was taken away from his father's cabin by the Indians. The words sounded sweet to him. He followed the strange man. He did not know where he was going, except that it was to some place called home. When he got to the hotel, he went in and sat down. He did not know what else to do.

Presently the landlady came in. Seeing a strange little boy in army blue, she said, "Whose child are you?"

Peter did not know whose child he was. Since the soldiers left him, he didn't seem to be anybody's child. As he did not answer, the landlady spoke to him rather sharply.

"What do you want here, little boy?" she said.

"A drink of water," said Peter.

A little boy nearly always wants a drink of water.

"Go through into the kitchen there, and get a drink," said the landlady.

Peter opened the door into the kitchen, and went through. In a moment two arms were about him. Peter knew what home meant then. His sister, Matilda, had recognized her lost brother Peter in the little soldier boy. The next day he was put into a wagon and sent out to Rushford, where his mother was living. The wanderings of the little captive were over.

THE GREATEST OF TELESCOPE MAKERS.

Three great inventors in this country were portrait painters. Fulton, the builder of steamboats, was one of them; Morse, who planned our first electric telegraph, was another; and Alvan Clark, who found out a way of making the largest and finest telescopes in the world, was another.

Alvan Clark was the son of a farmer. When he was eighteen years old, he set to work to learn engraving and drawing. He had no teacher. After a while he began to draw portraits. Once he sent to Boston to get some brushes to paint with. When the brushes came, there was a piece of newspaper wrapped round them. In this bit of newspaper was an advertisement that engravers were wanted. He went to Boston, and found regular work as an engraver.

When he was not busy engraving, he was studying painting. After some years he became a painter of portraits and miniatures. He lived at Cambridgeport, near Boston.

While Mr. Clark was living at Cambridgeport, his son was at a boarding school. The young boy had become interested in telescopes. He learned that there were two kinds of these instruments. One brought the stars near by showing them in a curved mirror. The other magnified by means of glasses that the light shone through. He had read that it was very hard to grind these glasses or lenses, as they are called, so that they would be correct. The telescope that used the mirror was not so good, but it was easier to make. So George Clark made up his mind that he would make a reflecting telescope; that is, one with a mirror in it.

The mirror in such a telescope is made of polished metal. One day somebody broke the dinner bell at the boarding school. George dark picked up the pieces of brass and took them home.

These pieces of brass he put into a retort. A retort is a vessel that will bear great heat, and that is used for melting metals and other substances. Young Clark put some tin into the retort with the brass. When the two metals were melted together, he poured the liquid into a mold. When it became cold, it was a round flat piece. Such a piece is called a disc.

Alvan Clark, the father, was a very ingenious man. He was a fine marksman. One reason that he could shoot so well was that his eye was so true. Another was that he made his own rifles, and made them better than others.

When Mr. Clark found his son trying to make a telescope out of the pieces of a bell, he became interested in telescopes. He studied all about them in order to help the boy with his work. He helped his son grind the metal disc into a concave mirror; that is, a mirror that is a little dish-shaped. With this they made a telescope with which they could see the rings of Saturn, and the little moons that revolve round Jupiter.

After Mr. Clark had made this little telescope, he made larger reflecting telescopes that were very powerful. But he found that no telescope with a mirror in it could be very good.

He now said to his son that they would make a refracting telescope; that is, one in which no mirror is used, but which brings the distant stars to the sight by the light shining through lenses. Lenses are large glasses that are regularly thicker in one part than in another. The glasses you see in spectacles are small lenses.

George Clark, the son, told his father that the books said that the grinding of such glasses was very difficult. Mr. Clark would not give it up because it was hard. He liked to do hard things. He had already spent a great part of his money trying to make good reflecting telescopes; but he made up his mind to give them up, and try to make a better kind. He first looked through the great telescope just put up for Harvard College. The large lens in this telescope was not perfect, and Mr. Clark's eye was so good that he could see what the small fault was. When he heard that twelve thousand dollars had been paid for this glass, he was encouraged to try to make such lenses. But there was nobody in this country who could show him how to do it.

He first got some poor lenses out of old telescopes. These he worked over, and made them better. By this means he learned how to do it. Then he got some discs of glass and made some new lenses. These were the best ever made in this country. But he was not satisfied. He kept on making better and larger lenses. With one of these he discovered two double stars, as they are called. These had never been seen to be double before.

But nobody in America would believe that some of the best telescopes in the world were made in this country, for even the English astronomers had to get their telescopes in Germany.

With one of his telescopes, larger than any he had made before, Mr. Clark now made a new discovery. He wrote about this to an English astronomer named Dawes. Mr. Dawes thought that a telescope that could make such a discovery would be worth having, so he bought the large lens out of this new telescope. Then he bought other glasses from Mr. Clark, and sold them again to other astronomers. In this way Mr. Clark became famous in England.
