La Salle received an accomplished education in one of the best seminaries in Europe. Upon graduating, he received from the professors a testimonial of his high intellectual attainments and his unblemished moral character. About the year 1669 he sailed from France for Canada. His object probably was to accumulate a fortune by the barter of European commodities for the furs and skins obtained by the Indians. He pushed forward to the frontiers, established trading houses, and in the well-freighted birch canoe, explored remote lakes and rivers.

At that time the whole of the great northwest of this country was an entirely unknown land. No one knew whether the continent was one thousand or ten thousand miles in breadth. It was the general impression that the waves of the Pacific were dashing against the rocks a few miles west of the chain of great lakes which fringed the southern shores of Canada. La Salle was meditating an expedition up the St. Lawrence, through the majestic chain of lakes to Lake Superior, from the western end of which he confidently expected to find easy communication with the Pacific Ocean. There he would again spread his adventurous sail, having discovered a new route to China and the Indies.

There was grandeur in this conception. It would entirely change the thoroughfare of the world's commerce. It would make the French possessions in the New World valuable beyond conception. This all-important route, between Europe and Asia, would be under the control of the French crown.

M. Frontenac, an ambitious and energetic Frenchman, was then governor-general of Canada. He entered cordially into the plans of La Salle, conferred frequently with him upon the subject, and was sanguine in the expectation that, by this great discovery, his own name would be immortalized, and he would secure the highest applause from the Grande Monarque, Louis XIV.

As early as the year 1660, the Indians had reported, at Quebec, that many leagues west of the great lakes there was a wonderful river, the Great River, the Father of Waters, the most majestic stream in the world, flowing from the unexplored solitudes of the wilderness in the north, far away into the unknown regions of the south.

One day a birch canoe, with a little band of hardy, wayworn voyagers, French and Indians, came paddling down the swift current of the St. Lawrence and ran their boat upon the beach where the little cluster of dwellings stood, called Quebec. They brought the startling intelligence that Father Marquette, a great and good man whom all knew, had discovered the Great River, which the Indians called the Mississippi, and had followed down its majestic current for hundreds of leagues, until he had reached the thirty-third degree of latitude. He had ascertained, beyond all question, that it emptied its flood into the Gulf of Mexico. This important discovery, it was claimed, gave to the French, according to the received law of nations, the whole valley of the Mississippi and its tributaries, however great that valley might prove to be.

This intelligence was received with every demonstration of public rejoicing. It gave, as it was supposed, to France a new world of boundless resources. The garrison band played its most exultant airs. Salvos of artillery echoed along the majestic cliffs. There was feasting, dancing, and singing, and the spacious church was thronged with worshippers praising God with the national anthems of Te Deum.

This great event gave a new impulse and a new direction to the ambition of La Salle. He at once conceived the idea of establishing a series of military and trading posts along the whole length of the lakes, and upon all the important points of the great river and its tributaries. But even then he was but little aware how magnificent was the realm which these tributaries watered. He would thus, however, in the name of the King of France, take military possession of the whole territory.

Governor Frontenac gave his most cordial approval to the gigantic plan. His own mind was greatly excited by the thought of the grandeur of a chain of forts extending from the mouth of the St. Lawrence to the Gulf of Mexico. He urged La Salle to go immediately to France, seek an audience with the king, lay the plan before him, and seek the royal patronage. The renowned Colbert was then minister of finance and marine. The governor furnished La Salle with letters to the minister which would secure for him a respectful reception.

La Salle, a penniless adventurer, recrossed the ocean. It was the year 1675. His plan at once attracted attention, and he was cordially received by both minister and king. The courtiers rallied around him with much enthusiasm. The king, having honored him with the title of chevalier, authorized him to rebuild, on the shores of Lake Ontario, Fort Frontenac, which was falling to decay, and invested him with the office of seignory or governorship of the fort and its adjacent territory.
