"A seashell," replied Mumps. "I thought I could hit Dick Rover with it."

"Humph, you had better take some lessons in throwing," muttered the bully. "You didn't come within a dozen feet of him."

"Never mind; I showed them I wasn't afraid of them," said Mumps, and turned away. Then he looked back anxiously. "I hope they pick it up and see what's inside!" he murmured. "Oh, but ain't I tired of this crowd! If ever I get out of this, you can wager I'll turn over a new leaf and cut Dan Baxter dead."
