"No, it's the postscription," replied the Robin, very seriously; "but, somehow, I never remember it till I come to it. I suppose it's put at the end so that I won't forget it the next time. You see, it's about the only exercise I have."

"I should think it was very good exercise," said Dorothy, trying to look serious again.

"Oh, it's good enough, what there is of it," said the Robin, in an offhand way.

"But I'm sure there's enough of it," said Dorothy.

"There is enough of it, such as it is," replied the Robin.

"Such as it is?" repeated Dorothy, beginning to feel a little perplexed. "Why, it's hard enough, I'm sure. It's enough to drive a person quite distracted."

"Well, it's a corker till you get used to it," said the Robin, strutting about. "There's such a tremendous variety to it, you see, that it exercises you all over at once."

This was so ridiculous that Dorothy laughed outright. "I should never get used to it," she said. "I don't believe I know a single one of the answers."

"I do!" said Bob Scarlet, proudly; "I know 'em all. It's 'No' to everything in it."

"Dear me!" said Dorothy, feeling quite provoked at herself, "of course it is. I never thought of that."
