Thus from the Atlantic coast we have passed to the Mississippi without crossing one single stream of water; but we have crossed at least twelve famous pathways between streams that flow north and south--routes of travel, which, when studied, give us an insight into the story of days long passed which cannot be gained in any other way. Over these paths pushed the first explorers, the men who, first of Europeans, saw the Ohio and Mississippi. Possessing a better knowledge of their routes and their experiences while voyaging in an unknown land, we realize better the impetuosity of their ambition and the meaning of their discoveries to them. We can almost see them hurrying with uplifted eyes over these little paths, tortured by the luring suggestions of the glimmering waterways in the distance. Whether it is that bravest of brave men, La Salle, crossing from Lake Erie to the Allegheny, or Marquette striding over the little path to the stream which should carry him to the Mississippi, or Céloron bearing the leaden plates which were to claim the Ohio for France up the difficult path from Lake Erie to Lake Chautauqua, there is no moment in these heroes' lives more interesting than this. These paths crossed the dividing line between what was known and what was unknown. Here on the high ground, with eyes intent upon the vista below, faint hearts were fired to greater exertions, and dreamers heavy under the dead weight of physical exhaustion again grew hopeful at the camping place on the portage path. Of all whose ambitions led them over these little paths, none appeal more strongly to us than the daring, patient missionaries who here wore out their lives for the Master. Each portage was known to them, better, perhaps, than to any other class of men. Here they encamped on their pilgrimages, though, from being spots of vantage which excited them onward, they were rather the line of demarcation between the near and the distant fields of service, and all of them full of trial and suffering and seeming defeat. Nowhere in the North can the heroism of the Catholic missionaries be more plainly read today in any material objects than in the deep-worn, half-forgotten portage paths which lay along their routes. The nobility of their ambitions, compared with those of explorers, traders, and military and civil officials, has ever been conspicuous, but the full measure of their self-sacrifice cannot be realized until we know better the intense physical suffering they here endured. If the study of portage paths results only in a deeper appreciation of the bravery of these black-robed fathers, it will be worth far more than its cost.
