“I will,” he said grimly.

The park superintendent told Miss Gordon to stand at the foot of the stairway. In that way she would block off any possible escape, should the boys elude Mr. Karwhite.

All the Brownies gathered beside the teacher, ready to assist her if their help was needed.

Armed with the stick, Mr. Karwhite started up the stairway.

He made no attempt to muffle his footsteps. As he reached the balcony, the door suddenly flew open.

“Jeepers!” cried one of the boys, belatedly warning his companions. “It’s Old Karwhite!”

The other boys poured out of the house like ants from a disturbed hill. Their escape, however, was cut off.

“I’ve finally caught up with you,” the park superintendent said. “You’re coming with me!”

“Aw, have a heart,” pleaded one of the boys. “We aren’t doing any harm.”

“You’ve mixed up park signs, pulled valuable shrubs, not to mention the damage you’ve done here.”
