His mother and James looked up, wondering what Rollo meant. He was looking out at the side of the carryall, at something about the wheel.

"What is it," said his mother.

"Why, here is a large fly trying to light on the wheel, and every time his legs touch it, it knocks them away. See! See!"

"Yes, but you must not attend to him now. You must listen to my lecture. You promised to give your attention to me."

So James and Rollo turned away from the window, and began to listen again.

"I have told you now," said she, "of one kind of playthings—those that give pleasure from their novelty only. There is another kind—those that give you pleasure by their use;—such as a doll, for example."

"How, mother? Is a doll of any use?"

"Yes, in one sense; that is, the girl who has it, uses it continually. Perhaps she admired the looks of it, the first day it was given to her; but then, after that, she can use it in so many ways, that it continues to afford her pleasure for a long time. She can dress and undress it, put it to bed, make it sit up for company, and do a great many other things with it. When she gets tired of playing with it one day, she puts it away, and the next day she thinks of something new to do with it, which she never thought of before. Now, which should you think the pleasure you should obtain from a ball, would arise from, its novelty, or its use?"

"Its use," said the boys.

"Yes," said the mother. "The first sight of a ball would not give you any very special pleasure. Its value would consist in the pleasure you would take in playing with it.
