We find them on Lake Huron, Lake Superior, and Lake Michigan, laboring vigorously as of old, but in a spirit not quite the same. Now, as before, two objects inspired their zeal, the "greater glory of God," and the influence and credit of the order of Jesus. If the one motive had somewhat lost in power, the other had gained. The epoch of the saints and martyrs was passing away; and henceforth we find the Canadian Jesuit less and less an apostle, more and more an explorer, a man of science, and a politician. The yearly reports of the missions are still, for the edification of the pious reader, stuffed with intolerably tedious stories of baptisms, conversions, and the exemplary deportment of neophytes; for these have become a part of the formula; but they are relieved abundantly by more mundane topics. One finds observations on the winds, currents, and tides of the Great Lakes; speculations on a subterranean outlet of Lake Superior; accounts of its copper-mines, and how we, the Jesuit fathers, are laboring to explore them for the profit of the colony; surmises touching the North Sea, the South Sea, the Sea of China, which we hope ere long to discover; and reports of that great mysterious river of which the Indians tell us,--flowing southward, perhaps to the Gulf of Mexico, perhaps to the Vermilion Sea,--and the secrets whereof, with the help of the Virgin, we will soon reveal to the world. The Jesuit was as often a fanatic for his order as for his faith; and oftener yet, the two fanaticisms mingled in him inextricably. Ardently as he burned for the saving of souls, he would have none saved on the Upper Lakes except by his brethren and himself. He claimed a monopoly of conversion, with its attendant monopoly of toil, hardship, and martyrdom. Often disinterested for himself, he was inordinately ambitious for the great corporate power in which he had merged his own personality; and here lies one cause, among many, of the seeming contradictions which abound in the annals of the order. Prefixed to the _Relation_ of 1671 is that monument of Jesuit hardihood and enterprise, the map of Lake Superior; a work of which, however, the exactness has been exaggerated, as compared with other Canadian maps of the day. While making surveys, the priests were diligently looking for copper. Father Dablon reports that they had found it in greatest abundance on Isle Minong, now Isle Royale. "A day's journey from the head of the lake, on the south side, there is," he says, "a rock of copper weighing from six hundred to eight hundred pounds, lying on the shore where any who pass may see it;" and he farther speaks of great copper boulders in the bed of the River Ontonagan.
