“Steam-engine,” suggested Nelson sotto voce.

“Chi-chi-Chicora!” blurted Tom finally in a hoarse whisper.

“What?” asked Dan. “The Chicora? Then, Clint’s there visiting Doctor Powers. Wonder who’s with him?”

“I think Thorpe went along in the launch,” said Nelson.

“Lu-lu-let’s go back,” suggested Tom uneasily.

“What for? It’s better to have Clint here than at camp, I think,” said Dan. “Come on. Did you hear any one, Tommy?”

“No, but I could see a light in the main house.”

“That’s it, then; Clint and Thorpe are paying a call on Powers, probably about the water sports. Shall we go on? What do you say?”
