"But—but—he ducked us," protested Ned.
"He did nothing of the sort."
"What—didn't duck us? Guess I know water when I feel it," objected Walter.
"You were ducked, all right, but it is I, not Juan, who am responsible for that."
"You?" questioned the lads all at once.

"But he had the pails."
"I gave them to him, after pouring the water over you. That's what is known as circumstantial evidence, young gentlemen. Let it be a lesson to you to be careful how you convict anyone on that kind of evidence."
"Fellows," glowed Chunky, "we've made a mistake. Let's make it right by ducking the Professor."
The boys looked over Professor Zepplin critically.
