It is difficult to apply a statistical table to the study of the question of conversions. These are mental operations of infinite variety, both in their origin and in their ways; for the methods of Providence are as many and as diverse as the shades of human thought upon which they act. It may be remarked, however, that the different Protestant sects furnish very unequal contingents to the little army of souls daily returning to the true faith; and it is a curious fact that the two sects which furnish the most are the Episcopalians, who, in their forms and traditions, approach nearest to the Catholic Church, and the Unitarians, who go to the very opposite extreme, and appear to push their philosophical and rationalistic principles almost beyond the pale of Christianity. These two sects generally comprise the most enlightened and intellectual people of North America. On the other hand, the denominations which embrace the more ignorant portions of the population (such as the Baptists, the Wesleyan Methodists, etc., etc.) furnish, in proportion to their numbers, but few converts. The principal Catholic review in the United States (_Brownson's Review_, published in New York) is edited by a well-known convert, whose name it bears, and who was formerly a Unitarian minister. Further North--in New England--there is another Catholic group, of recent origin, formed of the Puritan states of Connecticut, Massachusetts, and Rhode Island. The first see here was established by Bishop Cheverus only sixty years ago. These bishoprics, however, have already acquired importance; for in the diocese of Hartford the Catholics are now sixteen per cent, of the whole population, and the rapidity of their increase and the completeness of their church organization give us ground for bright hopes of their future progress. Immigration {12} here does much to promote conversions, and it will not be extravagant to anticipate that in the course of a few years the number of the faithful will be doubled. _The Pilot_, the most important Catholic journal in the country, is published in Boston.
