The moonlight strengthening, or his own eyes becoming every instant more accustomed to the gloom, enabled him to make out a tall, dark figure, erect and motionless as a statue; then his heart gave a jump as he recognized the outlines of a mortar-board and gown.

In an instant he realized that he and his comrades had walked into a trap; and without a second's hesitation he turned and bolted, coming into violent collision with Jarvis and Roden, who were following closely on his heels.

"Cave!Scoot!"

The retreat became a rout. At the moment no one clearly understood what was the matter; but those who had not entered the shed, seeing their companions rush out like rabbits from a furze bush, joined in the stampede.

As they ran, and as if to increase their confusion and hasten their flight, a big squib came whizzing over the playground wall and exploded with a bang in their very midst. This single firework formed the whole of Sloper's contribution to the entertainment; for, finding that there was no response, he came to the wise conclusion that something must have happened; and so, putting the rest of the squibs in his pocket, he ran off home.

It was not until the entrance to the school building was reached that Brookfield found breath enough to gasp out,—

"'Twas old Chard himself! I nearly walked into his arms! Some one's split, and he was waiting there to collar the whole pack of us!"

Shamefacedly, and with looks of apprehension, the discomfited band assembled in the schoolroom for prayers.

"Hullo!" whispered Oliver to Brookfield in a bantering tone. "How about the firework display?"

The football captain was in no mood for joking, and answered with a surly "Shut up!" He was momentarily expecting the door to open, and the headmaster to enter and commence an investigation.
