In June, 1676, Monseigneur Laval, on his return from France as bishop of Quebec, visited Montreal to receive postulants into the new religious communicants of the "Congregation," which approved by him in 1669 and later confirmed by royal letters, was now confirmed by him in an authentic act, shortly after his arrival at Quebec—but whose rules were still to be examined and approved, which did not occur until January 24, 1698. Historians date from the above epoch the adoption of the religious habit, worn by the Sisters of the Congregation of Notre Dame to this day. In order to prepare her rules wisely Marguerite Bourgeoys determined to go to France for advice and experience, having been previously elected as the first superior. The opportunity was offered her in November as a companion to the wife of the governor, Madame Perrot, who had been advised to go to France for the good of her health. On her return she was followed to Montreal by Louis Frins, the servant of M. de Maisonneuve, who had died in Paris on September 9, 1676, as well as by several young girls, who were sent out to the colony at the expense of the seminary.

In 1676 the Mountain Mission was commenced. [128] To encourage the Indians to settle with the Europeans, various attempts had already been made. This nomadic people could not be civilized as long as the trail, by the lakes and rivers and through the forest, called them to the pursuit of the chase or the lust of battle. Thus we have seen the Jesuits had already formed their Christian Indian settlements at Madeleine la Prairie on the south shore across the St. Lawrence. But now the Sulpicians would do the same on the island, on the slope of Mount Royal, and today the site of Montreal College, on Sherbrooke Street, with its old-time Martello towers, marks the scene of the Mountain Mission. Quarrels had arisen among the chiefs at La Prairie and thus the dissentients joined the Christian band at the mountain, while the La Prairie Mission was transferred to the Sault St. Louis, known as the Caughnawaga Reservation. By 1681, it was determined to conduct schools for the children of redskins, and M. François Vachon de Belmont, who came as a deacon to Canada in this year, was named director of the boys' school. That for the girls was to be under the care of the Sisters of the Congregation. Marguerite Bourgeoys says that the Mountain Mission was the first place on the island where the Indians came for instruction. On arriving, M. de Belmont began to build a little chapel, dedicated to Notre Dame des Neiges, and a straggling village of a few irregularly built bark huts clustered round it. In these lived the missionaries and the sisters, and round them were the wigwams of their neophytes, Huron and Iroquois. Fearing attack from the non-Christian tribes, M. de Belmont, a priest since September 14, 1681, had built by 1685 a palisade surrounding his settlement which boasted of four bastions. These fortifications were gradually strengthened. The schools were soon in operation. "In the Mountain Mission and that of the Sault de la Prairie de la Madeleine (Sault St. Louis); in those of Sillery and Lorette, the only Indian villages we have, boys are now being taught to read and write. In the Mountain Mission of Montreal the Congregation nuns apply themselves to the instruction of the little girls and make them do needle work," is the description of M. Duchesneau in a letter to the minister of finance, dated November 13, 1681. Later on these children were taught to knit, spin and do lace work, the government providing grants of money for women to instruct them. In 1685 Monseigneur de St. Vallier, Laval's successor, visited the Mountain Mission and gave this account of its success: "The daughters of the Congregation, now spread over the different parts of Canada, have in the Mountain Mission a school of about forty Indian girls, whom they clothe and bring up 'à la Française.' They are also taught the mysteries of faith, manual labour, the hymns and prayers of the church, not only in their own tongue, but also in ours, that they may be brought little by little to our manners and customs."
