“In the name of all-possessed!” cried Toby Tew, “tell us the rest—quick!”

“The wavy line is the other channel, almost parallel with Crab Channel,” Don was willing enough to speak, “and the line that looked like the stem of the ship was really the shore line between the channels while——”

“The bow part must have been the—” Doc Morgan was shaking with excitement, “—the little channel alongside of the boathouse.”

“Gosh-a-mighty!” Toby leaped up, “that cross in the tracing was right by the boathouse, then. In the name of all-possessed—to think I’ve been storing dories right over treasure—let’s——”

“Just a moment!” The Police Chief entered with Mr. McLeod. “Nobody goes out of here except Don and his Airlane Guard. The treasure is the Indian’s property if found. No one else gets a chance to rush ahead and secure it—if found! Stand aside, Ti-O-Ga!”

The Indian, realizing that he must obey, moved away. Don dashed out.

Anyone in the upper windows at the hangar side, watching, could have seen the Dragonfly take off almost before it had rising speed, and go roaring into the dark swamp air. They could have seen, and some did see, a landing flare go over near the sheet of water where the boathouse stood.

“Did you telephone—and get the answer we expected?” Don asked Garry as they tied up the Dragonfly to a part of the old wharf.

“I did, and Chick is about to unload what he found—in the boarding house room you mentioned!”

They took some cased objects, and a projector head, out of the cockpit, carried them into the old hovel, set them up by hooded flashlight rays, and then sat down in a corner to wait.
