“No, I mean crack it now!” went on Danny. “I double-dare you!”

Bert did not like to take a dare. Much less did he like to be “double-dared.” He peered over the top of his big book. The teacher was busy at some papers on her desk.

Slowly Bert raised the paper snapper as high as he dared. Then, swinging his arm put into the aisle, where there was plenty of room, he brought his hand down smartly, checking it half way.

Bang! went the snap-cracker, with a noise like a pistol shot.

“Oh!” gasped a number of the pupils.

Some of them laughed out loud.

The teacher looked up quickly from her desk.

“Who did that?” she asked quietly.

There was no answer for a moment.

“I want the boy or girl who did that to come up here to my desk,” went on the teacher.
