Colonel Heathcote established a grist mill on the Mamaroneck River near the original bridge crossed by the "old Westchester Path," and a saw mill high up on that river, now the site of the present Mamaroneck Water Works, upon which site there continued to be a mill of some kind until it was bought two years ago to establish those works. He made leases at different points throughout the Manor, but did not sell in fee many farms, though always ready and willing to do so, the whole number of the deeds for the latter on record being only thirteen during the twenty-three years or thereabout which elapsed between his purchase from Mr. Richbell and his death. Some of these farms, however, were of great extent. He did not establish as far as now known any Manor Courts under his right to do so. The population was so scant, and the Manor like all others in the county, being subject to the judicial provisions of the Provincial Legislative acts, there was really no occasion for them. He personally attended to all duties, and matters, connected with his Manor and his Tenants, never having appointed any Steward of the Manor. Papers still in existence show that his Tenants were in the habit of coming to him for aid and counsel in their most private affairs, especially in the settlement of family disputes, and he was often called upon to draw their wills- But space will not permit mention of incidents and facts of only personal or local interest, or of details of his general management of the Manor, or his agricultural management of his demesne lands, which included besides those attached to his Manor House the whole of that portion of the East Neck below the old Westchester Path now called De Lancey's Neck.
