Terms

New York and Massachusetts agreed to divide the rights in question with a treaty signed December 16. The states agreed that all of the land in question, about 6 million acres (24,000 km²), would be recognized as part of New York State. Massachusetts, in return, obtained the right of preemption, the title to all of the land, giving it the exclusive right to extinguish by purchase the possessory rights of the Indian tribes (except for a narrow strip along the Niagara River, the title to which was recognized to belong to New York). The compact also provided that Massachusetts could sell or assign its preemptive rights.
