For the greater portion of our journey we shall find neither road nor pathway; here we shall climb and follow long, ragged mountain crests, well nigh inaccessible, in some spots never trod by human foot save the wandering hunter's; there we shall drop down to a lower level and find that on our watershed run roads, canals, and railways. At many points in our journey we shall find a perfect network of modern routes of travel, converging perhaps on a teeming city which owes its growth and prosperity to its geographical situation at a strategic point on the watershed we are following. And where we find the largest population and the greatest activity today, just there, we may rest assured, human activity was equally noticeable in the old days. As we pass along we must bear in mind the story of days gone by, as well as the geography which so much influenced it. It is to the earliest days of our country's history that our attention is attracted--to the days when the French came to the St. Lawrence and the Great Lakes, and sought to know and possess the interior of the continent, to which each shining tributary of the northern water system offered a passage way. Passing the question how and why New France was founded on the St. Lawrence, it is enough for us to know she was there before the seventeenth century dawned, and that her fearless _voyageurs_, undaunted by the rushing tides of that great stream, were pushing on to a conquest of the temperate empire which lay to the southward. Here in treacherous eddies, the foaming rapids, and the mighty current of that river, they were soon taught the woodland art of canoeing, by the most savage of masters; and in canoes the traders, trappers, missionaries, explorers, hunters, and pioneers were soon stemming the current of every stream that flowed from the south. But these streams found their sources in this highland we are treading. Heedless of the interruption, these daring men pushed their canoes to the uttermost navigable limit, and then shouldered them and crossed the watershed. Once over the "portage," and their canoes safely launched, nothing stood between them and the Atlantic Ocean. It is these portage paths for which we shall look as we proceed westward. As we pass, one by one, these slight roadways across the backbone of the continent, whether they be miles in length or only rods, they must speak to us as almost nothing else can, today, of the thousand dreams of conquest entertained by the first Europeans who traversed them, of the thousand hopes that were rising of a New France richer and more glorious than the old.
