The old man ahead dodged back. He was none too quick, for the piece of slate, flying through the air with the sharp edge down, dropped where he had stood an instant before. The old man took off his hat and ran his fingers through his hair. Amy saw it was Uncle Philander-Behind-His-Back.

The discovery, interesting in itself, meant nothing to Amy at the moment. She uttered a heart-broken wail. She had spoken before the week was up. By her impulsive exclamation she had forfeited the hundred dollars. Though she knew acknowledgment must be made to her partners in the undertaking, since as she had broken the spell the others were automatically released from the obligation of silence, to face any of them at that moment seemed impossible. Without a word to Mr. Frost, Amy wheeled about and started for home, the tears running down her cheeks.

Breathing hard, Uncle Philander-Behind-His-Back trotted after her. What he meant to say does not matter, since the discovery that Amy was in tears resulted in the inquiry, "What are you crying for, hey?"

"I lost it," Amy sobbed. "I spoke."

Her companion seemed to be deliberating. "I s'pose you mean the hundred dollars."

"Of course I mean the hundred dollars. But I don't see how I could have helped it. I couldn't walk on deliberately and see a sharp piece of slate drop on a man's head."

"'A HUNDRED DOLLARS AIN'T ANY TOO MUCH TO PAY FOR HAVING YOUR LIFE SAVED'"

"I came in to-day thinking I'd have a talk with that friend of yours," said Mr. Frost, "seeing she seemed to be the head one in this thing. I was going to tell her that now I'd thought it over, my conscience wasn't quite easy about this agreement of ourn. I'm afraid it is too much like placing a bet."

Amy's jaw dropped as she looked at him. Her tears dried instantly, the moisture evaporated by the fires of her wrath. But either because her usually ready tongue was out of practise after six days of idleness, or because the realization of the perfidy of the old man produced a momentary paralysis of her vocal chords, not a word escaped her parted lips.
