Providence, however, had not deployed so strong a force for no purpose beyond the capture of these converts. A very few missionaries might have sufficed for that; but it was now time to prepare the land for the great European immigration which was to cause the astonishing growth of the United States. Spreading themselves over the vast area of the Union, the emigrants found everywhere these veteran soldiers whom the French Revolution had sent forth into the New World as pioneers, tried both by the pains of persecution and the labors of apostleship. Before this great human tide the old emigrant priests were like the primitive rocks which arrest and fix geological deposits, The Catholic part of the tossing flood invariably settled around them and their disciples. All over the West the churches founded by the old French settlers increased, and new ones sprang up wherever a Catholic priest established himself. From that moment the grand progressive movement has never ceased. The blood of the martyrs of France, the spirit of her banished apostles, became fruitful of blessings, of which the American churches are daily sensible. The first bishop in the United States had been appointed in 1789. Four years afterward another see was erected at New Orleans, La., which, ten years later, became a part of the United States; and in 1808, so rapid had been the Catholic development, that three new bishops were consecrated--one for Louisville, Ky., another for New York, and the third for Boston, Mass. Two of these sees were occupied by the French missionaries who had founded them--Bishop {6} Flaget at Louisville, and Bishop Cheverus at Boston. That of New York was entrusted to a venerable priest of English [Irish] origin--the Rev. Luke Concanen. In the whole United States there were then sixty-eight priests and about 100,000 Catholics. Lei us now glance at the rapid increase of the American Church up to our own day. I. From the States of Maryland and Pennsylvania the Church was not long in spreading into Virginia, New York, Kentucky, and Ohio. The establishment of sees at Louisville and New York was followed by the erection of others at Philadelphia in 1809, and Richmond and Cincinnati in 1821. The two Carolinas, in which the Catholics had hitherto been an obscure and rigorously proscribed class, received a bishop at Charleston in 1820. New Orleans, a diocese of French creation, was divided in 1824 by the erection of the bishopric of Mobile. The old French colonies in the far West were the nucleus around which were formed other churches. The dioceses of St. Louis, Mo. (organized in 1826), Detroit, Mich. (1832), and Vincennes, Ind. (1834), all took their names from ancient French settlements, and were peopled almost exclusively by descendants of the French Canadians who were their first inhabitants.
