“Yes; and, if he hadn’t, I never could have guessed them! Oh, he is clever!”

“And when do the answers have to be sent in?”

“April first.”

“H’m! an appropriate day! Well, Patty, as your heart is so set on this thing, carry it through; but don’t ever begin on such a task again. Now, Mr. Van Reypen may help you, if you wish, but I mean it when I say he must not come here to call more than twice in one week.”

“All right,” agreed Patty, cheerfully. “May I send him some puzzles to guess, father?”

“Well, I won’t have you writing to him. Not letters, I mean. But, if you can’t guess a puzzle, you may send it to him, and I trust you not to let this permission develop into a correspondence.”

“No, sir; I won’t,” said Patty.

But, after Mr. Fairfield had gone away, the girl turned to Nan, with a perplexed look.

“Whatever ails father,” she said, “to talk to me like that?”

“He’s right, Patty. You don’t see the difference, but there is a great difference between your friendship for Kenneth and Roger, which dates from your schooldays, and your sudden acquaintance with Mr. Van Reypen, who is older, and who is a far more experienced man of the world.”
