"If—if I-I die they'll hang for this!" spluttered Ed Simpson.

"No danger of your drowning, you're too mean," said Jack. "Besides it's only up to your knees. Stand up and wade out."

By this time the three lads, their clothing dripping with water, had managed to stand upright. They reached down under the dancing wavelets and loosened the nooses.

"You'll pay for this, Jack Ranger," shouted Adrian, shaking his fist at our hero.

"All right, I'm ready whenever you are," was the cool answer. "Come on, fellows, we don't want to be late for the lecture," and he started from the water, followed by his chums.

"I'll have you arrested for damaging my clothes," exclaimed Ed.

"And I suppose you'd tell on the witness stand about what you intended to do to ours," went on Jack. "I guess you'll cry 'quits,' that's what you'll do. You tried to play a trick on us, but you got left. So long. Don't miss the lecture."

He scrambled ashore, his comrades doing likewise, while the three lads who had taken such an unexpected bath waded out as best they could. They were sorry looking sights.

"But I don't exactly un-d-d-d-erstand how it it h-h-h-appened?" stuttered Will, who had not had hold of one of the ropes.

"I just made slip nooses, and placed them where they'd have to step into them before they could lay hands on the clothes," explained Jack. "Budge gave me the signal when they were inside the ropes."
