Mr. _Samuel B. Smith_, who has been not only a Roman Priest, but has had several _cages of nuns_ under his sole management, questioned Maria Monk expressly respecting those affairs, customs and ceremonies, which appertain only to nunneries, because they cannot be practiced by any other females but those who are shut up in those dungeons; and, after having minutely examined her, he plainly averred that it was manifest she could not have known the things which she communicated to him unless she had been a nun; not merely a scholar, or a temporary resident, or even a novice, but a nun, who had taken the veil, in the strictest sense of the appellative. This testimony is of the more value, because the conclusion does not depend upon any conflicting statements, of partial or prejudicial witnesses, but upon a fact which is essential to the system of monachism; that no persons can know all the secrets of nunneries, but the Chaplain, the Abbess, and their accomplices in that "mystery of iniquity." Mr. Smith's declaration in one other respect is absolutely decisive. He has declared not only that Maria Monk has been a nun, but also that the descriptions which she gives are most minutely accurate. Mr. Smith also testifies that the account which Maria Monk gives of the proceedings of the priests, the obscene questions which they ask young females, and their lewd practices with them at auricular confession, are constantly exemplified by the Roman Priests; and he also confirms her statements, by the testimony of his own individual experience, and actual personal acquaintance with the Canadian nunneries, as well as with those in the United States, and especially of that at Monroe, Michigan, which was dissolved by Mr. Fenwick, on account of scandalous impurity, several years ago. Mrs. ----, a widow lady now in New York, who formerly was a Papist in Montreal, and was recently converted to Christianity, solemnly avers, that the Priest Richards himself, conducted her from the Seminary through the subterraneous passage to the nunnery, and describes the whole exactly in accordance with the statement of Maria Monk. _Mr. Lloyd_, who was in business a number of years adjacent to the nunnery, and who is intimately acquainted with those priests, their characters, principles, and habits, avows his unqualified conviction of the truth of the "Awful Disclosures." _Mr. Hogan_, who was eighteen months in the Jesuit Seminary at Montreal, and in constant intercourse and attendance upon Lartigue and his accomplices, unequivocally affirms, that Maria Monk's complex description of those Priests are most minutely and accurately true. One hundred other persons probably can be adduced, who, during their residence in Canada, or on their tours to that province, by inquiries ascertained that things in accordance with Maria Monk's delineations are the undoubted belief of each class of persons, and of every variety of condition, and in all places which they visited in Lower Canada.
