"Seems like it wasn't bad enough for us to be wrecked, and marooned on this queer island, but we have to fall across the trail of some unknown parties who may be up to all sorts of unlawful dodges, for all we know. But Thad, tell me more of what you saw and heard."
"When I started out from here," the scoutmaster began, "I knew that I'd probably only have to look around at this end of the island, because no sensible man was going to take up his quarters where these storms always strike in. And then I figured it out that the chances were, these parties, if there were more than the one fellow I'd seen sneaking around, and spying on us, would want to be down close to the water, for a good many reasons. You can understand that, Allan?"
"Yes, and I think that notion would have come to me, just as it did you," replied the other promptly, showing that he was following the narrative closely.
"Well, that being the case," resumed the scoutmaster, "I stuck to the lower part of the land, climbing over and around such outcropping rocks as I came across. The moon wasn't helping me very much, though it's up there behind the clouds; and on that account you see the darkness is never so bad as when there's no moon at all.
"It wasn't so very long before I heard something knocking softly near by, and listening carefully I made up my mind that it must be a boat that was kept in a snug cove perhaps, and yet where it got more or less wash of the sea beyond.
"That was just what it turned out to be, Allan, a fair sized motorboat, stoutly built, and yet something of a hummer when it would come to speed. Her outlines told me this as soon as I could make her out down in the berth she occupied between the rocks where they had protected the sides of the little basin with logs to keep her from chafing too much.
"Now, speed indicates that the people owning that boat expect to show a clean pair of heels, as they say, at times. They want to be in condition to skip out in a hurry, and be able to outrun any ordinary craft that might try to overhaul them. Wouldn't you think that way, Allan?"
"You're speaking my mind to a dot, Thad."
"But I wasn't satisfied wholly, and made another move, to see whether they had any sort of a cabin around. Seemed to me that if they were using Sturgeon Island for some sort of shady business, they ought to have a shelter. Well, I found it before ten minutes had passed, and by just creeping along what I made out to be a regular trail leading from the boat up the shore a piece."
"Good for you, Thad; no woodsman could have done better!" exclaimed the other scout, who, having had practical experience extending through many trips into the wilderness with hunting parties, was pretty well posted on the numerous little "wrinkles" connected with woods lore.
