That tremendous sea, stretching for several hundred miles away to the west, opened appalling possibilities in the way of a gale. The staunchest steamers that ever plied the fresh water seas would sometimes be as putty in the grasp of a summer storm; and what of the three puny mosquito craft that were as chips on the water?

At three o’clock Herb announced that his engine was getting worse instead of better. And about the same time a welcome hail from George, who was moving along in the van as usual, told that he had by the aid of his glasses sighted a shelter.

“Then it’s us to go ashore,” declared Jack; nor was any one sorry in their hearts; since a little while before a distant sound like thunder had been borne to their ears from the low-down patch of hovering clouds.

The retreat promised to be all the shelter they wanted, though it would hardly have answered for larger boats. Immediately all became as busy as beavers, the two tents being raised, and stoutly secured, so that any ordinary gale could not carry the canvas off like a balloon.

Jack had hardly finished his share of the work before he got out his rod, and busied himself in trying for trout; for he fancied that they were to be found in the clear waters near by this cove, where a limpid little stream emptied into the Great Lake.

Nick, they all noticed, stuck close to camp. It would have to be something very attractive that could induce him to wander far from his fireside, especially when the camp was pitched on Canadian soil, where they grew such queer kitties.

This time it was Jimmie who seemed destined to get into a peck of trouble. Jack always declared that there seemed to be an evil spirit forever hovering around their camp, looking for chances to accomplish his work; and let there appear the least kind of an opening, and he was ready to jump in.

Jimmie was not much of a hunter or fisherman, though able to do either on occasion. But he did have a little fancy for wild flowers, and liked to pry around on occasion, seeing what he could discover.

Now, at this late day in the season, he knew he was not apt to run across any of these pretty gems of the woods; but there seemed to be some sort of fascination about poking here and there examining a bunch of magnificent moss of a pattern he had never set eyes on before, measuring some giant ferns, and watching the antics of a family of squirrels. These had their home in an old hollow tree close by, and seemed filled with mild curiosity concerning the intruders on two legs that had taken up quarters so boldly adjoining the cove.

Herb and George were busily engaged with the balky engine, trying to find out just what ailed the thing, so that it could be remedied once and for all. In the end they felt positive that the blame could be located and effectually cured. At least it was to be hoped so; otherwise the Tramp would have to tow the larger boat back to the Soo, where the trouble could be abated at the hands of a machinist.
