"I've an idea," he announced at length. "The question, of course, is why should the man who set the canoe adrift have landed on a desolate place like this? I expect it's just its desolateness that brought him here. Now the smugglers probably find it difficult to get hold of the dope in Canada, and they may have to save it up in small parcels until it's worth while to send the schooner through. She couldn't come often with only a case or two, because it wouldn't pay and it would increase the chances of somebody's seeing her. On the other hand, they may not be able to get rid of the stuff immediately when she brings a big lot, and in that case they'd be likely to make a cache of part of it where nobody would be likely to strike it and their friends could come for it later. This island ought to be just the place." Harry made a sign of assent. "I guess you've hit it first time, but I'll go up and get the mainsail on her. I can manage it alone with two reefs in, and you can stay where you are until your clothes are a little drier, unless I call you." He went out, and Frank heard a clatter of blocks and flutter of canvas. After that there was a sharp rattling as Harry hauled in the anchor chain, and then the boat suddenly slanted over with a jerk which flung Frank backward against the side of her. As he got up he heard the water splash about her bows. A few minutes later they began to swing sharply up and down, and the thuds against them made it evident that the sloop was plunging close-hauled through a short, head sea. By and by the plunges grew more violent, and struggling into his clothes, which were partly dry, Frank put out the lamp and crawled out into the well. For a minute or two he could see nothing as he held on by the weather coaming, though he felt the buffeting of the wind and the sting of the spray upon his face. Then by degrees he made out that the sloop was lying down on one side, with the small black strip of her double-reefed mainsail slanting sharply above her, and a filmy white cloud flying at her bows. Suddenly the frothing water began to glitter, and on looking up he saw that the moon, which had grown brighter, had just emerged from behind a bank of flying cloud. Then Harry who sat at the helm called to him. "Look yonder! Just over the bowsprit end," he cried. Frank, gazing where his companion told him, saw a bright red twinkle low down above the sea and apparently two or three miles away. "A fire!" he exclaimed. "On the island by the point, isn't it?" "A signal," Harry assented. "Guess it's to show the schooner men the bush gang are ready." He broke into a laugh which reached Frank faintly. "They're figuring we're safe on the island out of the way. You couldn't see that fire from the beach we were left upon." "What are you going to do?" "Stand right on to where the fire is. We have to make a long leg on this tack, anyway. When we're close up with the point we'll consider. Get a little more head sheet in if you can."
