"But when you said smugglers, what did you mean, Giraffe?" questioned
Step Hen.

"Oh! Don't you know that they have heaps of trouble with such law-breakers all along the Canadian border?" demanded the tall boy. "You see, there's a heavy duty on a lot of things that can come into Canada free, or with only a small sum to pay; and whenever men can make money taking chances, they're just bound to try it. Why, I understand that millions of dollars are lost to the Government every year just in the goods smuggled across the border all the way from Maine to the Pacific ocean."

"Whew! and yonder craft might be one of the tricky boats engaged in that business; is that what you mean, Giraffe?" asked Bumpus, again staring hard after the strange black powerboat which was larger than the Chippeway Belle, and apparently much better able to meet the heavy seas that must sweep across the lake when the wind reached a certain strength.

"Oh! I don't say that, remember," quickly replied the other; "because it's only a guess on my part, and I haven't anything to show for proof. I was just giving you the benefit of a bright thought that came into my brain, that's all. There may be something in it, and again, p'raps them fellows are just a pleasure party; or some sportsmen heading, for a favorite fishing place."

"Then if we followed 'em, we'd stand a show to find where the fish lie," suggested Bumpus; showing that at least he had not forgotten about his recent wager, even in the midst of all this excitement.

"Better mind your own business, I think," remarked Allan.

"Yes," added Giraffe, "if so be they turned out to be a bad lot, they'd think we kept poking our noses in just to arrest them; and in that case chances are we'd get our fingers burned."

"But what do you think they might be, Thad?" persisted Step Hen, noticing that the pilot of the expedition had as yet not given any opinion on the matter.

"Oh! any one of the explanations you fellows have put up might cover the bill," Thad, went on to say. "The idea came into my mind that perhaps now those men might be game-fish wardens."

"W-what!" gasped Bumpus; "d'ye mean to tell me they have such things on a big lake like this? Why, I thought they were only needed ashore, where ponds and rivers require looking after."
