Mr. Pedagog puffed away in silence. It was evident that the argumentum ad hominem did not please him.

"Well," he said, after awhile, "possibly you are right. If a man wants a library to be a small British Museum—"

"He will take better care of his rarities than the Idiot does," said the Bibliomaniac, putting the rare Leech back into its place. "If that were mine I'd put it out of the reach of my children."

"I didn't know you had any," said the Idiot, eagerly.

"Oh, you know what I mean," retorted the Bibliomaniac. "You place Dryden on the top shelf where Tommy and Mollie cannot get at him. But this book, which is worth ten larger paper editions of Dryden, you keep below, where the children can easily reach it. It's a wonder to me you've been able to keep it in its present superb condition."

"The mind of a child," said Mr. Pedagog, sententiously, "is above values, above all conceits. It is the mind of sincerity, and a rare book has no greater attraction to the boy or girl than one not so favored."

"That is not my reason," said the Idiot. "I know children pretty well, and I have observed that they are ambitious, and in a sense rebellious. They want to do what they cannot do. That is why, when mothers place jam on the top shelf of the pantry, the children always climb up to get it. If they would leave it on the dining-room table, within easy reach, the children would soon cease to regard it as a thing to be sought for. Make jam a required article of diet and the little ones will soon cease to want it. So with that book. If I should put that out of Tommy's reach, Tommy would lie awake nights to plan his campaign to get it. Leaving it where it is he doesn't think about it, doesn't want it, is not forbidden to have it, and so it escapes his notice."

"You have the right idea, the human idea," said Mr. Pedagog, and even the Bibliomaniac was inclined to agree. But just then Tommy happened in, with Mollie close after. The boy walked straight to the bookcase, and Mollie gathered up the large shears from the Idiot's table, and together they approached their father.

"Pa," said Mollie, holding up the scissors, "can I borrow these?"

"What for?" asked the Idiot.
