The year 1650 may be chronicled as that of the first general movement towards agriculture. The constant fear of Iroquois' attacks had kept the settlers pent up within the walls of the fort, although there had been since 1643 individual attempts by Charles d'Ailleboust and others outside.[62] The activity started by Jeanne Mance in putting into cultivation the 200 arpents lately conceded by the Associates of the Company of Montreal to the Hôtel-Dieu encouraged others to take to the land and to build their dwellings on the concessions which they now demanded from M. Maisonneuve, since it was now thought there was a likelihood of peace. These early grants were only of thirty arpents and to ensure as great protection as possible against Iroquois attacks, they were clustered around the fort and the brewery. In granting these lands, however, the seigneurs stipulated that they could be exchanged later for others at a remote distance, for the location at present used was reserved for the future city, for the building of the market place, the port and other public purposes. What may be called the history of mutual building societies now starts, for as the number of workmen were limited, the inhabitants, led by the motives of fraternal charity and public spirit, formed associations to help one another in the clearing of their lots and in the construction of their homes. Thus a contract dated November 15, 1650, between Jean des Carris and Jean Le Duc, binds them to assist each other to build at common expense a ho, for each, on a clearing, of ten acres each, made by them, and that if one of them fell sick the work should be continued by the other without remuneration. In the present case after the clearing had been made and the house built on Jean des Carris' concession, the war intervening would not allow similar work to be done on that of Jean Le Duc, and in consequence Jean Le Duc received from his partner 580 _livres_ in recompense for his services. The harvest of this year was very successful; "particularly at Montreal where the lands are very excellent," is the account in the "Relations."
