It is also a fact publicly avowed by certain Montreal Papists themselves, and extensively told in taunt and triumph, that they have been employed as masons and carpenters by the Roman Priests, since Maria Monk's visit to Montreal in August, 1835, expressly to alter various parts of the Hotel Dieu Convent, and to close up some of the subterraneous passages and cells in that nunnery. This circumstance is not pretended even to be disputed or doubted; for when the dungeons under ground are spoken of before the Papists, their remark is this: "Eh bien! mais vous ne les trouverez pas, à present; on les a caché hors de vue. Very well, you will not find them there now; they are closed up, and out of sight." Why was the manoeuvre completed? Manifestly, that in urgent extremity, a casual explorer might be deceived, by the apparent proof that the avenues, and places of imprisonment and torture which Maria Monk describes are not discoverable. Now that circumstance might not even been suspected, if the Papist workmen themselves had not openly boasted of the chicanery by which the Priests, who employed them, expected to blind and deceive the Protestants. For in reference to the Romanists, a Popish Priest well knows that nothing more is necessary than for him to assert any absurdity, however gross or impossible, and attest it by the five crosses on his vestments, and his own superstitious vassal believes it with more assurance than his own personal identity. But the filling up and the concealment of the old apertures in the nunnery, by the order of the Roman Priests are scarcely less powerful corroborative proof of Maria Monk's delineations, than ocular and palpable demonstration. 2. Some of the circumstances attending Maria Monk's visit to Montreal, in August, 1835, add great weight in favour of the truth, which no cavils, skepticism, scorn, nor menaces, can counterbalance. We will however state one very recent occurrence, because it seems to us, that it alone is almost decisive of the controversy. A counsellor of Quebec--his name is omitted merely from delicacy and prudential considerations--has been in New York since the publication of the "Awful Disclosures" His mind was so much influenced by the perusal of that volume, that he sought out the Authoress, and most closely searched into the credibility of her statements. Before the termination of the interview, that gentleman became so convinced of the truth of the picture which Maria Monk drew of the interior of the Canadian Nunneries, that he expressed himself to the following effect:--"My daughter, about 15 years of age, is in the Ursuline Convent at Quebec. I will return home immediately; and if I cannot remove her any other way, I will drag her out by the hair of her head, and raise a noise about their ears that shall not soon be quieted."
