A mystic conviction took possession of him. If he had any value, that shout would be achieved. But its agent would be something greater than himself. Prepared or unprepared for it, the shout would come, if he was worthy.

It was a very hot afternoon. Miss Tibbet croaked at the blackboard like a machine. A desultory dog was barking somewhere with insensate yelps. The geranium before the closed windows drooped in the heat. Flies were droning aimlessly.

A huge shout swept suddenly into every corner of the room, slapped Miss Tibbet's face like the palm of a hand. There was an intense silence. All eyes turned to Philip's face, which was flushed furiously red, unhappy, exultant.

"Yes, Miss Tibbet!"

"Why did you make that noise?"

"I don't know!"

"Did somebody stick a pin into you?"

"No!"
