BLUFFING UP TO THE BIG GAME "That explosion was fearful, what there was of it," Dick declared to Chief Coy.

It was evening, and the head of the local police department had stopped the boys on the street for additional information on the subject.
"What did it look like ?" asked Chief Coy.
"There came a big flash and a loud bang in the same instant, and Mr.Garwood was hurled over on his side.

The queer part of it was that the explosion didn't do any real damage to the bench, though there wasn't a piece of the glass mortar left that was big enough to see." "The explosion all went upward.

It didn't work sideways or downward ?" asked Chief Coy.
"That's the way we saw it," Dick replied.

"And it didn't hurt either you or Darrin ?" "Not beyond the big scare, and the shock to our ear-drums." "I wonder what the explosive could have been ?" mused the chief aloud.
"I don't know what was in the mortar in the first place, sir," Dick Prescott went on.
