"It's only good luck it isn't!" put in Jack. "If we hadn't gone out they might have exploded their powder, and, in the morning our initials would have been found at the bottom of the statue, burned in the stone."

A little later loud talking was heard from the direction of Adrian's room. It quieted down, after a while. But there was a strenuous session at chapel the next morning, and Adrian and his cronies were given extra lessons to do.

For a week or more after this all the students had to buckle down to hard study, as the annual examinations were approaching. Jack and his chums had little time for sports of any kind, as they had a number of lessons to master in addition to their regular work. But by diligence they kept up with the requirements, and, about two weeks before the time set for the closing of the school, they found themselves on even terms.

"I'm ready for some fun," announced Jack, one evening. "I've been good and quiet so long I can feel my wings sprouting."

"Better go easy," cautioned John Smith.

"I'm going to; as easy as I can," replied Jack. "But I've got to do something or break loose."

"Shivering side-saddles!" exclaimed Nat Anderson. "Let's have a burglar scare."

"How?" asked Sam.

"I'll think of a plan," Nat went on. "Howling huckleberries, but I too am pining for a little excitement, Jack."

"Well, trot out your plan," Jack said. "We haven't got much time."
