Legends are preserved that lead to the belief that there may have been navigators of the Great Lakes before the Indians, and it is generally believed that the latter were not the first occupants of the Lake Superior region. It is said that the Lake Superior country was frequently visited by a barbaric race, for the purpose of obtaining copper, and it is quite possible that these people may have been skilled navigators. [Illustration: THE WOODEN BATEAUX OF THE FUR TRADERS ] Commercial navigation of the Great Lakes, curiously enough, first assumed importance in the least accessible portion. The Hudson Bay Company, always extending its territory toward the northwest, sent its bateaux and canoes into Lake Superior early in the seventeenth century. To accommodate this traffic the company dug a canal around the falls of the St. Marie River, at the point we now call "the Soo." In time this pigmy progenitor of the busiest canal in the world, became filled with debris, and its very existence forgotten; but some years ago a student in the thriving town of Sault Ste. Marie, poring over some old books of the Hudson Bay Company, noticed several references to the company's canal. What canal could it be? His curiosity was aroused, and with the aid of the United States engineers in charge of the new improvements, he began a painstaking investigation. In time the line of the old ditch was discovered, and, indeed, it was no more than a ditch, two and a half feet deep, by eight or nine wide. One lock was built, thirty-eight feet long, with a lift of nine feet. The floor and sills of this lock were discovered, and the United States Government has since rebuilt it in stone, that visitors to the Soo may turn from the massive new locks, through which steel steamships of eight thousand tons pass all day long through the summer months, to gaze on the strait and narrow gate which once opened the way for all the commerce of Lake Superior. But through that gate there passed a picturesque and historic procession. Canoes spurred along by tufted Indians with black-robed Jesuit missionaries for passengers; the wooden bateaux of the fur traders, built of wood and propelled by oars, and carrying gangs of turbulent trappers and voyageurs; the company's chief factors in swift private craft, making for the west to extend the influence of the great corporation still further into the wilderness, all passed through the little canal and avoided the roaring waters of the Ste. Marie. It was but a narrow gate, but it played its part in the opening of the West.
