"It's about Nat Poole," continued Ben Basswood. "I guess you had some kind of a run-in with him, didn't you?"

"Not exactly," answered Roger. "We caught him tormenting Professor Potts and we put a stop to it."

"Well, you had some trouble with Nat's dad, didn't you?"

"Yes," answered Dave. "Did Nat tell you?" he added quickly.

"No, I know of the whole thing by accident. I had to go to the building where Mr. Poole has his new office. While I was waiting to see a man and deliver a message for my dad I overheard some talk between Mr. Poole and Nat. It was mighty warm, I can tell you!"

"What was said?" demanded Phil.

"Mr. Poole accused Nat of something and Nat, at first, denied it. Then Mr. Poole said something about arrest, and Professor Potts, and Nat got scared and begged his father to save him. Then Mr. Poole mentioned Dave and a pistol and said he couldn't do anything if that's the way matters stood, and Nat began to beg for dear life, asking his father to let Dave alone this time. At last Mr. Poole said he would, but the way he lectured Nat was a caution. He said he wouldn't give Nat a cent more of spending-money this summer."

"Hurrah, that lets you out, Dave!" cried Roger. "The case against you is squashed."

"The Pooles will have to let it drop," added the shipowner's son. "And I am mighty glad of it."

"I hope you are right," said Dave, and his face showed his relief.
