He read the roll of the class; every boy was there.

“Scarborough, you may go to the blackboard and demonstrate the Fifth Theorem; Dennison, you the Sixth; Westby, you the Eighth. The rest of you will solve at your seats this problem.”

He mounted to the blackboard himself and wrote out the question. While he had his back turned, he heard some whispering; he looked over his shoulder. Westby was lingering in his seat and had obviously been holding communication with his neighbor.

“Westby,”—Irving’s voice was sharp,—“were you trying to get help at the last moment?”

“I was not.” Westby’s answer was prompt.

“Then don’t delay any longer, please; go to the blackboard at once.”

“Yes, sir.”

Westby moved to the blackboard on the side of the room—the one at right angles to that on which Irving and Scarborough were at work.

Irving finished his writing, dusted the chalk from his fingers, and returned to his seat. The boys before him were now bent industriously over their tablets; Scarborough, Westby, and Dennison were drawing figures on the blackboard, using the long pointers for rulers and making beautiful circles by means of chalk attached to pieces of string. A glance at Westby showed that youth apparently intent upon solving the problem assigned him and at work upon it intelligently. Irving began to feel serene; he proceeded to correct the algebra exercises of the Fourth Form, which he had received the hour before.

A sudden titter from some one down in front, hastily suppressed and transformed into a cough, caused him to look up. Morrill, with his mouth hidden behind his hand, was glancing off toward Westby, and Irving followed the direction of the glance.
