“It’s nothing,” declared the captain, waving his hand. “Anybody in this place?”

They went through the house from top to bottom and Don showed them the storage room. But now there remained but a few of the smaller articles, everything else had been carted off.

“After we chased them off last night they must have loaded their stuff into a boat and run off with it,” remarked the captain. “But what I want to know is what kind of a boat have those fellows got? Must have some kind of a power cruiser that runs up here close to the house by way of a creek.”

A little later on, they found that this was so. While looking over the cellar which Don had not seen at all, owing to the darkness, they found at one end a door which led directly out into a thicket. Through the midst of this thicket was a path, and soon they came across a narrow creek, in which lay their own dinghy.

“Sure,” nodded the captain. “They run their boat up here and kept out of sight. Last night they loaded that stuff and slipped away.”

Don and Terry rowed out in the dinghy, while the captain went around to the cove for the dory. Soon the captain caught up to them under power and they arrived at the Lassie at the same time. Jim was overjoyed to see his brother safe and sound, and they all united in thanking the old captain.

“Avast there, stow that stuff!” he protested. “Nothing to thank me for. I never liked the looks of that crew, and I always felt that they had no business on my island. I’ve lived there for twenty years. Now, it’s time we got down to business. We’ve got to get over to Stillwell at once.”

“What for?” asked Don.

“We must make a report to the authorities about these fellows and have that house taken over. Start your engine running. It won’t take us long.”

They started the engine and headed the sloop across the gray water toward the town of Stillwell. Don was starved, of course, and Jim, as soon as his duties permitted, made him a hearty meal. The captain insisted upon taking the tiller and in a few hours they were gliding in beside the long dock at the town. Jim stood at the bow while Don slowly throttled the engine down, and when the bow was close to the dock he leaped ashore, snubbed the rope around a post, and then pushed the bow off with one foot, so as not to allow it to scrape. The Lassie came to a halt, riding quietly up and down.
