Mr. Payson had arisen, and was walking up and down the room with his hands behind his back. He stopped to deliberate beside the bookcase, then he took down a volume at random. "Suppose I ask him what the first word is on page one hundred of this book."

He looked over at Cayley, then down at the title of the book.

"The Astrology of the Old Testament—queer I should put my hand on that! I'll try it. I won't look at the page at all." He put the book back on the shelf. "Can't you suggest something? Suppose you give me a question that you know the answer of and I don't."

Blanchard Cayley sought for an idea, his eyes fixed on the ceiling. Then he said slowly: "I used to know a girl once in Sacramento who lived next door to me. Try Vixley on her name, why don't you?"

"Good! I'll do it. Now one more."

"You might ask him the number of your watch."

"That's a good idea; then I can corroborate that on the spot."

"You'd better let me see if there's one there, though," Cayley suggested. "I believe sometimes they are not numbered. Just let me look."

Mr. Payson took out his watch and handed it to the young man, who opened the back cover and inspected the works. He noted the number, took a second glance at it and then snapped the cover shut. "All right, if he can tell that number, he's clever." He handed it back to Mr. Payson. "When did you say you were going to see him?" he asked.

"Next Tuesday or Wednesday, I expect," was the reply. "I've got to go up to Stockton to-morrow, and I may be gone two or three days attending to some business. By the by, Cayley, I heard rather a queer story last week when I was up there. You're interested in these romantic yarns of California; perhaps you'd like to hear this."
