The others agreed to this, and all quickly donned their shoes and clothing and then made for the fire-escape, which they so often used in preference to the regular stairway.

As they ran across the campus they saw three figures steal forth from the Colby Hall boathouse. The three figures made for the motor-boat at the dock, and in a minute more the Rovers heard the motor of the boat and then saw the craft glide out into the semi-darkness of the night.

“Now what were they doing at the boathouse?” questioned Jack.

Struck with a sudden fear, the young major broke into a run, followed by the others. They dashed into the boathouse, which was dark, and in one corner saw a faint glare.

“It’s a fire!” gasped Fred. “Somebody has set the place on fire!”
