The "Hospital of the Hotel-Dieu de Ville Marie" is on the northeastern edge of the city, almost under the shadow of the mountain, and is one of the largest buildings in Canada, its dome rising one hundred and fifty feet over the spacious chapel. It was in this hospital, when first founded in a small way in 1647, that Mademoiselle Mance took up her abode. There are now over five hundred persons in the building, and it is conducted by eighty cloistered nuns, who never go outside the grounds. They are of the Order of St. Joseph, caring for the sick, the orphan, and the old and infirm. The "Sisters of the Congregation of Notre Dame," the "Black Nuns," as they are called, have their Mother House in Montreal, this being the teaching order founded by Marguerite Bourgeoys in 1653, she having then come out to Canada with Maisonneuve on his second voyage. "To this day," writes Parkman, "in crowded schoolrooms of Montreal and Quebec, fit monuments of her unobtrusive virtue, her successors instruct the children of the poor and embalm the pleasant memory of Marguerite Bourgeoys. In the martial figure of Maisonneuve, and the fair form of this gentle nun, we find the true heroes of Montreal." These "Black Nuns" conduct seventeen schools in the city, with over five thousand pupils. Their most extensive establishment is just out of town, on what are known as the "Monk Lands," and is called "Ville Marie." There are no less than six hundred nuns and novices in this order, and their pupils number twenty thousand in Canada and the United States.
