Caleb Heathcote, Mayor of the Borough of Westchester," his heirs and assigns forever in fee simple absolute, excepting only a small tract previously deeded as a gift to James Mott and his wife in 1684, and another small piece deeded as a gift to John Emerson on the 30th of Sept 1686, which latter was subsequently conveyed by Emerson to Mott by deed dated 25th of June 1690, the wives of both being daughters of Mrs. Riehbell. The deed to Colonel Heathcote also provided that " this Deed of Sale shall not obliedge the said Ann Riehbell to make good to the said Caleb Heathcote any of the outlands within the Two Miles further than her right and title therein." With these exceptions Ann Richbell's entire right title and estate under the deeds and Patents of her husband John Riehbell was conveyed to, and vested absolutely in, Colonel Caleb Heathcote.'

The above reservation to Mott referred to a small piece of upland at the entrance to that portion of the East Neck, subsequently, and to this day, called "De Lancey's Neck," of about thirty acres deeded by Mrs. Riehbell to Mary and James Mott on the 8 August 1684, which from Mott's heirs finally became vested in the late Giles Seaman after whose death it passed by sale to the late Isaac Hall, who sold it in his lifetime to its present owner, who built upon the premises the fine summer hotel now called, from his own name, the "Rushmore."
