“Oh, shut up!” cried the bully.

“I think I’ll try some milk,” said Mumps. “Phew, what a flavor!”

To sweeten it he put in some sugar, and at once he had the milk boiling and foaming.

“This is what’s the matter!” cried Reff Ritter. “It’s the milk and sugar that is doctored. Somebody put seidlitz powders in them!”

“Dump the sugar and milk away,” said the bully, and this was done. Then the crowd had to get a new lot before they could go ahead with their meal. Pepper and his chums had a hearty laugh over the incident.

That night, when Pepper was on guard duty, he took his package of firecrackers with him and during his spare time fixed some of the crackers so that they would have extra long stems, made of nothing but ordinary cotton cord. Then, when he was off duty, he placed the firecrackers around the camp, lighting each fuse as he did so.

“Now wait, and you’ll see some fun,” he whispered to Andy, Dale, and the others.

For a few minutes there was silence, and then one of the crackers went off. It was of good size and the noise sounded like a gun shot.

“Corporal of the guard!” came the cry.

“What post?” was the question asked by the corporal, as he rushed out of his tent.
