“But, father,” said Rollo, after being silent a little while, “I don’t think I should get tired of my beautiful gardens very soon: I don’t think I should get tired even of looking at pictures of them.”

“Should you like to try the experiment?”

“Yes, sir,” said Rollo, very eagerly.

Rollo’s father had a great many books of pictures and engravings of various kinds in his library; and sometimes he used to allow the children to see them, but only a very few at a time. They had not yet seen them all. He only allowed them to see them as fast as they had time to examine them thoroughly, and read about them and understand them. But now he said to Rollo,

“I could let you have all the books of prints and engravings I have got, and see them all at one time, and that would be giving you Aladdin’s lamp, exactly, so far as my pictures are concerned.”

“Well,” said Rollo, clapping his hands.

“But then, in a short time, you would get tired of looking at them; you would become satiated, and would in fact spoil the whole pleasure by attempting to enjoy it too fast. But then I think it would perhaps do you good.”

“How, father?”

“Why, by teaching you the value of moderation, and the uselessness of Aladdin’s lamps in all human enjoyments. It would be a very valuable experiment in intellectual philosophy, which I think it very probable might be of use to you. So, if you please, you may try it.”

“Well, father, I am sure I should like to see the pictures.”
