"We recommend the following communications to all persons who doubt the wickedness of Nunneries. The young gentleman who sent us the letter is now in this city, and we have heard the same statements from other witnesses. That subterraneous passages from the Seminary to the Nunneries, we ourselves have seen, and close by the spot designated by our correspondent:-- (STATEMENT OF J. M.) _"Underground passage from the Jesuit Seminary to the Hotel Dieu Nunnery, Montreal._ "I have been informed that you are endeavoring to obtain facts and other incidental circumstances relative to the Black Nunnery, in Montreal, and the disclosures concerning it, made by Maria Monk, in which are many hard things, but hard as they are, they are not indigestible by us Canadians; we believe that she has told but a small part of what she must know, if she was but half the time there which she says she was. Maria Monk has mentioned in her book something about the underground passage which leads from the Black Nunnery to other places in Montreal. That fact I know by ocular demonstration, and which nine tenths of the Canadians also will not deny, for it has been opened several times by the labourers, who have been digging for the purpose of laying pipes to conduct gas and water. While preparing a place for the latter I saw one of those passages; the earth being removed by the labourers, they struck upon the top of the passage, and curiosity led them to see what was beneath, for it sounded as though there was a hollow. They accordingly removed the large flat stones which formed the top of the passage. Many persons were looking on at the time, and several of them went down into it; when they returned after a few minutes, they stated that they went but a short distance, before they came to an intersection of passages, and were afraid to proceed further. Shortly after, several priests were on the spot, and prevented the people from further examining it; and had the place shut up immediately, while they stood by and guarded it until it was all done. The appearance of that part of the passage was the same as I saw while they were laying the water pipes. The floor of it in both [illegible] where I saw it was clean to appearance, with the exception of a little dirt that fell in on opening them, and of stone flagging. I have heard much about these underground passages in Montreal, in which place I have spent the most of my days. I give you my name and residence: and if you should be called upon from any quarter for the truth of this statement. I am ready to attest it upon oath; and there are others in this city who have witnessed the same things. The places where those openings were made in the underground passages were in St. Joseph street for the water pipes; and for the gas pipes in Notre-Dame street, near Sacrament street, at a short distance from the Seminary.
