“Well, listen to this: In hoc signo vinces.”
“Harry, don’t tell me they’re in hock!”
“No, some one came down here in a motor-boat, got the rest, and went chugging back again.”
“You’re a perfect ghoul!,” cried Gordon, mimicking Miss Crosby. “You’ve picked up a loose chug—you know you have! It’s just wonderful!”
“Do you want to know what In hoc signo vinces means, you little monkey?”
“I shall never be happy till I find out.”
“Well, then,” said Harry, pointing to the grease spot, “it means, “By this sign thou wilt conquer.”
“But I don’t see how you know they went off in the motor-boat, Harry. Even supposing there was a motor-boat here, there’s nothing to show the fellows went off in her. It might have been just somebody that stopped here to visit the camp.”
“Well,” said Harry, “they didn’t go back the way they came, that’s sure. They’d never have left that note under the rock if they’d gone right back past it. There’s no other road leading away from here, and I don’t believe they’d have struck right across country. I’m pretty sure they wouldn’t follow the railroad track either, so there’s nothing left but the motor-boat. We shall now count the railroad ties from here to Port Henry.”
