“So every one thought, about fifty years ago,” said Mr. Harvey; but men who have gone to the countries where sloths are, and seen them in the high trees, tell a very different story.  They say that the sloth’s home is in the branches, as much as a fish’s is in the water; and he is there a strong and happy animal, although he looks so weak and miserable on the ground.  He lives on fruit, and moves from one branch and one tree to another, with considerable swiftness.  So you see that the sloth enjoys himself as well as any of us; and I have no doubt that he was created for some good purpose, although we may not be able to understand precisely what it is.

“But do not some animals eat each other?” asked Thomas.

“Yes,” replied Mr. Harvey; “but this is of great use to man.  What would the farmer do with all the insects that destroy his grain, if many of them were not eaten by little birds; and how much of his fruit would these very birds destroy, if they, too, were not eaten by hawks!  If animals did not destroy each other, they would soon become so numerous as to crowd man from the earth.”

CHAPTER XI.

Alice Gray.

One morning, after the three boys had taken a pretty long walk, they came to a small cottage, standing by a garden, round which was a neat hedge.  Part of this garden was planted with vegetables, and part with flowers, while many vines and sweet brier bushes stood before the cottage door.  There were also large, white roses, which Samuel thought finer than any he had yet seen; and in a corner of the garden farthest from the house, stood two bee hives.  As the boys passed by, a young woman came out on the piazza, and asked them in.  John and Thomas had often been here; so they opened the gate and passed through with their cousin.  The young woman, whose name was Alice, brought out chairs, and some new milk in bowls, for each of them to drink.  Then she walked with them through the garden, showing them through the flowers, and telling their names.  He was much pleased with the bee hives; they were made of wood, with glass tops, so that the bees might be seen at work.  After watching them for some time, they returned through the garden to the cottage door.  At this moment an old lady came to the door, and spoke to Mr. Harvey’s boys.  Samuel observed that she was very feeble, and that her voice could scarcely be heard.  She looked like one who had been often sick.  When they left the cottage, he asked who she was.

“Her name is Gray,” said Thomas.  “Alice is her daughter.  Mrs. Gray’s husband was a sailor, and when Alice was about three years old, he went on a voyage to catch whales, but was lost, with all the crew.  Mrs. Gray was poor, and had four children; and as no one in the town where she lived would help her, she opened a school for little boys and girls.  The money she got by teaching,
