Near the northern end of Lake Michigan, where the bluff-bowed ore-carriers and the big, low-lying, wheat-laden steel freighters from Lake Superior push out from the Straits of Mackinac and dispute the right of way, in the island divided channel, with the white-and-gold, electric lighted, wireless equipped passenger steamers bound for Detroit and Buffalo, there is a copse of pine and hemlock back from the shingly beach. From this copse—dark, blue, primeval, silent at most times as when the Great Manitou ruled his inland waters—there comes at time of storm a sound like the booming of an old Indian drum.
