Thence they started on May 28th, with a guide from the fort, and after a strenuous journey of twenty-two days reached Montreal on June 18, 1670.
OLD MAP OF MONTREAL
M. de Galinée on his return made a corrected copy of his map, which he sent to M. Talon, with a copy of the "prise de possession," already described, and these were of great use later, to the French government, which sent them to London in 1687 as evidences of the pretensions which the French claimed over Lakes Erie and Ontario, and the neighbouring countries.
GALINEE'S MAP, 1669
Dollier de Casson wrote a history of this voyage but no copy has been found. Though the journey was unsuccessful in the conversion of the Indians, yet it paved the way to succeeding explorations which were quickly sent by Talon, and to the eventual evangelization of these parts.
Of La Salle's experience, after leaving the Sulpicians, we have little to record, as he was lost to civilization; but we see him coming back at intervals to Montreal as his base to obtain supplies for his explorations. On the 6th of August, 1671, he received on credit "in his great need and necessity" from the hands of Migeon de Branssat, procureur fiscal of Ville Marie, merchandise to the sum of 454 livres tournois. Again on December 18, 1672, being in Montreal, there is an "obligation" recorded at the city greffe of a promise to pay, on the August following, the same sum in peltry or money, either at the house of Jacques Leber, where he lived, or at Rouen at the house of his relative, M. Nicholas Crevêt, king's councillor and master of accounts.
