The three friends worked hurriedly. When they had finished they had several packages. Down the trellis they went and out on the campus, which was shrouded in darkness.

They made their way to the foot of a statue of George Washington, which stood on a broad base in front of the school. There stood the Father of His Country, with outstretched arms, as if warning invaders away from the precincts of learning.

"They've been here!" said Sam in a whisper.

He pointed to some straggling black lines at the base of the figure, and to a thin thing like a string: which led over the grass toward the room of Adrian Bagot.

"They've put our initials in powder here," said Jack. "Trying to throw the blame on us when it goes off."

"We'll soon fix that," replied Sam. The three boys made some rapid movements around the statue, and then cut the thin thing which led to the room of young Bagot.

"I guess when he touches off that fuse he'll wonder what has happened," observed John Smith.

"Have you enough of the other fuse?" asked Jack.

"Plenty," replied the Indian student. "Have you changed the initials?"

"Every one," said Sam.
