distance above the present bridge between the towns of Mamaroneck and Rye where the river bends suddenly to the east and then takes a northerly course, a rocky reef originally crossed it nearly at right angles, causing the formation of " rapids." It was high enough to prevent the tide rising over it at highwater, so that the fresh water of the river always fell directly into the salt water of the harbour, and at low water with a strong rush and sound. It was thus a striking and unusual occurrence in nature, and is the source of the Indian name of the River itself and of the East Neck of which it was the eastern boundary. No authority has been found for another signification " the place of the rolling stones " that has been ascribed to the word " Mamaroneck " by Mr. Bolton. Rolling stones are not found anywhere in the neighborhood, the rocks being what the geologists call in situ, and the boulders of huge size and weight.

Richbell's Patent of confirmation from Governor Lovelace is dated October 16th, 1668. On the 14th of the ensuing November, twenty-eight days later, he conveyed the East Neck to Margery Parsons, his wife's mother, " for valuable consideration of certaine goods formerly delivered and paid unto me by Mrs. Margerj' Parsons upon the Island of St. Christopher's in America.^ Two days afterward, on the 16th of November 1668 Margery Parsons conveyed to her daughter Mrs. Richbell the East Neck " for that singular and dear affection I have and bare to my most dear daughter Mrs. Ann Richbell wife of the said Mr. John Richbell for her dutiful observance towards me." * By way of making this provision for his wife more secure, John Richbell settled the same East Neck upon her as a jointure, by a deed in trust to John Ryder dated 23d of April, 1669, " in consideration of a marriage long since had and solemnized between the said John Richoell and Ann his present wife," and therein describes the Neck as follows, "All that parcell or neck of Land where he now Lives called the East Neck, and to begin at the Westward part thereof at a certaine creeke lying, being, and adjacent by and betwixt y'' Necks of Land commonly called y" Great Neck, and the East Neck, and so to run eastward as farr as Momorononeck River, including therein betwixt the said two lines, all the land as well North into y' woods above Westchester Path twenty miles, as the lands belowe the Path southward towards the Sound."'
