La Salle was one of those who in the beginning believed the Mississippi flowed into the Vermilion Sea. If we may put faith in appearances, his original idea was not so much to descend the great river to its mouth, as to make his way across the continent to the great South Sea, and so to reach China and Japan. And the name of La Chine,[2] which La Salle gave his own residence, at Montreal, really seems an indication of what was then uppermost in his mind.

This is instructive as showing how slowly geographical knowledge of the westward half of the continent unfolded itself.

As we have said, Cavelier de la Salle was a man of one idea, practical in some things, visionary in others, but in pursuit of a purpose as steadfast as fate.

In 1666, at twenty-three, he found himself in Canada. He took up his residence at the upper end of the island of Montreal, where the St. Lawrence is broken up into rapids which to this day bear the name of La Salle's residence, La Chine.

Here La Salle quietly spent three years, hearing the while from the Indians who came to La Chine, all sorts of strange stories about the vast region toward the setting sun, and the people who lived in it.

We have seen the missions already firmly established on the Great Lakes. Joliet and Marquette had reached the Mississippi by one route and returned by another and different one, leading them through the heart of the great Illinois nation, to whom Marquette believed himself specially called. His labors among this people had left an impression highly favorable to those who might come after him.

It was from the Iroquois, who came to visit him at La Chine, that La Salle first heard of the Ohio. The passion for discovery seems to have found swift and intense development in him. He was young, ambitious and eager for adventure. La Salle was only twenty-six when he resolved to go in search of the Ohio.

Immediately he sold La Chine to procure an outfit. In the summer of 1669 he set out for the Iroquois country where we lose sight of him altogether. Yet, while no itinerary of his journey remains extant, his claim to have discovered the Ohio is conceded by his rival, Joliet.

Meanwhile, Frontenac, that man of action, was not idle. He was bent on opening the direct road to the western lakes, peaceably if he could, forcibly if he must, but at any rate to open it. To this end he now showed the Iroquois that he was not afraid of them by building a fort at Kingston,[3] which was called, in his honor, Fort Frontenac. This post gave the command of Lake Ontario to the French. It was at once a check and a menace to the Iroquois, who saw the mastery of the lakes slipping away from them but could not prevent it. Through his favor with Frontenac, La Salle secured from the king a grant of Fort Frontenac, which, in his hands, became not only an important trading-post, but the base of future contemplated discoveries. Here La Salle brooded over the projects which were to make him famous not for a day, but for all time.

For ten years more La Salle is found repairing his fortunes, maturing his plans, acquiring information, or studying Indian dialects. The Gulf of Mexico was to be reached, and a French port and colony established there into which all the trade of the river should flow. Thus the Mississippi, in French hands, was to be a wedge dividing the Spaniards in Florida from the Spaniards in New Mexico. Possessed of the two great waterways of the continent—the St. Lawrence and Mississippi—France was to take the first place in America. When all was ready La Salle laid his plans before the King.
