Almost in a jiffy, so it seemed, the masculine part of the senior dance party was out on the sidewalk of the side street.
"Don't you juniors and sophs show yourselves on Main Street for a full sixty seconds, unless you hear us raise a row at the back of the bank," advised Dick.
Somehow, none of the upper classmen seemed to think it strange for young Prescott thus to take command. He and his chums had discovered the attempt on the bank, and it seemed natural, just now, for the freshman leader to lead the whole school.
On tiptoe Dick and his chums led the way into the alley, the seniors following just as stealthily.
When the freshmen were within thirty feet of the lane Dick Prescott held up his hand, then signed to all hands to make the grand rush forward.
Just an instant before the High School boys could start, the earth suddenly shook and swayed under them, while on the frosty night air there came a great, sullen, fearsome—-
BOOM!
That was the explosion designed to blow open the door of the bank's vault.
