The Abbés Richard, Levadour, Dilhiet, and several others, passed through the forest and the wilderness, and joined the old French colonies which still survived around the ruins of the French military posts in the Northwest and in the valley of the Mississippi. They found there a few missionaries, whom the Canadian Church still maintained in those distant countries; but their ranks were thin, and they were old and feeble. This precious reinforcement enabled them to give a fresh impetus to the French Catholic congregations over whom they kept watch in the forest. Detroit, Vincennes, Cahokia, Kaskaskia, and afterward St. Geneviève and St. Louis in Missouri, ceded to the United States in 1803, received the visits of these new apostles, and experienced the benefits of their intelligence and zeal. Nearly all the places where they fixed themselves have since given their names to large and flourishing bishoprics. Several of the emigrant priests remained in Maryland and Virginia, and enabled the Sulpitians to complete the organization of their seminary, while at the same time they assisted Bishop Carroll in providing more perfectly and regularly for the wants of those central provinces which might be called the first home of American Catholicism. The number of the faithful everywhere increased remarkably. We can hardly estimate the extraordinary influence which these French missionaries exercised by their exemplary lives, their learning, their great qualities as men, and their virtues as saints; and the Anglo-Saxon inhabitants (who are thoroughly Protestant if you will, but for all that religious at bottom) were struck by their character all the more forcibly because it was so totally different from what their prejudices had led them to expect of the Catholic clergy.
