Years passed on. In spite of a vicious plan of government, in spite of the bursting of the memorable Mississippi bubble, the new colony grew in wealth and strength. And now it remained for France to unite the two extremities of her broad American domain, to extend forts and settlements across the fertile solitudes between the valley of the St. Lawrence and the mouth of the Mississippi, and intrench herself among the forests which lie west of the Alleghanies, before the swelling tide of British colonization could overflow those mountain barriers. At the middle of the eighteenth century, her great project was fast advancing towards completion. The lakes and streams, the thoroughfares of the wilderness, were seized and guarded by a series of posts distributed with admirable skill. A fort on the strait of Niagara commanded the great entrance to the whole interior country. Another at Detroit controlled the passage from Lake Erie to the north. Another at St. Mary’s debarred all hostile access to Lake Superior. Another at Michillimackinac secured the mouth of Lake Michigan. A post at Green Bay, and one at St. Joseph, guarded the two routes to the Mississippi, by way of the rivers Wisconsin and Illinois; while two posts on the Wabash, and one on the Maumee, made France the mistress of the great trading highway from Lake Erie to the Ohio. At Kaskaskia, Cahokia, and elsewhere in the Illinois, little French settlements had sprung up; and as the canoe of the voyager descended the Mississippi, he saw, at rare intervals, along its swampy margin, a few small stockade forts, half buried amid the redundancy of forest vegetation, until, as he approached Natchez, the dwellings of the _habitans_ of Louisiana began to appear. The forest posts of France were not exclusively of a military character. Adjacent to most of them, one would have found a little cluster of Canadian dwellings, whose tenants lived under the protection of the garrison, and obeyed the arbitrary will of the commandant; an authority which, however, was seldom exerted in a despotic spirit. In these detached settlements, there was no principle of increase. The character of the people, and of the government which ruled them, were alike unfavorable to it. Agriculture was neglected for the more congenial pursuits of the fur-trade, and the restless, roving Canadians, scattered abroad on their wild vocation, allied themselves to Indian women, and filled the woods with a mongrel race of bush-rangers.
