In July, 1616, the Récollet missionaries held at Quebec a conference with Champlain and other friends of their work, at which it was decided that they needed more missionaries, more French colonists, and a seminary for the education of Indian children. To obtain aid in these directions, Jamay and Le Caron soon afterwards went with Champlain to France, where at first they received but little help or encouragement. Jamay remained to forward the interests of the mission; while Le Caron, now appointed its superior, returned to Canada in the spring of 1617, accompanied by Father Paul Huet. A year later, desiring to work personally among the savages, Le Caron delegated to Father d'Olbeau his authority as superior, and spent a year at Tadoussac, with the Montagnais. During 1619-22, he labored at Quebec, then again wintered with the Montagnais; and in July, 1623, returned to the Huron mission, accompanied by Viel and Sagard (see _notes_ 25, 48). During his year's stay there, he did much to aid Champlain in securing the temporary treaty of peace which, in July, 1624, was concluded between the Iroquois, on one part, and the French and their savage allies on the other. In August, 1625, Le Caron went to France on the affairs of the mission, and returned the following year with Brother Gervase Mohier and a reinforcement of Jesuit missionaries. He remained at Quebec, as superior of his mission, until 1629, when all the priests were sent back to France by Kirk. As the Récollets expected to resume work on the Canadian mission, Le Caron was appointed its procurator in France; but he died on March 29, 1632,--according to Le Clercq--through grief at the exclusion of his order from Canada. Upon the invasion of Canada by the English, the Récollet missionaries had been urged by their savage disciples to take refuge with them in their towns, where they would be safe from attack, and could minister to the religious wants of the natives until the French should return. The fathers wished to accept this proposal; but as it was opposed by the council of Quebec, Le Caron felt obliged to decline it, for which he was afterwards blamed by some of his brethren in France. Full details of his work are given by Le Clercq and Sagard: the former copies a letter written by La Caron to his provincial at Paris, Aug. 7, 1618; also fragments of memoirs sent by him to that officer in 1624.--See Shea's _Le Clercq_, vol. i., pp. 134-137, and 213-224. He is said to have prepared a dictionary of the Huron language (_Ibid._, p. 249). Other MSS. of his were burned in March, 1631, as a result of sanitary measures then taken against a contagious disease in the convent of St. Margaret, near Gisors, Normandy, of which he was superior.--See "Memorial of the Récollets, 1637," in Margry's _Découvertes et établissements des Français dans l'Amérique septentrionale_ (Paris, 1876-86), vol. i., p. 11.
