Wetmore and Daniel Ewing became interested in Whiting's purchase in 1841, and they subsequently divided it into parcels stretching from the Hudson across the neck to Tippett's Brook. Thomson took the northerly parcel, on which stood a large stone house erected about 1822 on the site of the "Upper Cortlandts'," destroyed in that year by fire. Surrounded by well laid out and highly-improved grounds, it is now the residence of Waldo Hutchins. Near by is Hiram Barney's beautiful country-seat, " Cedar Knolls." The Whiting mansion is occu|)ied by James R. Whiting, Jr. Adjoining is the house of James A. Hayden. The late General John Ewen's country-seat on this tract is now occupied by his widow.

Hi'Dsox Park was laid out in 1853, on the westerly part of Samuel Thomson's tract. A single house on the river-side was the only one erected for many years. There is now a cluster of small dwellings known as " Cooperstown," on this tract.

North of Hudson Park, and extending across from the Hudson to the Albany road, was the old Hadley farm of two hundred and fifty-seven acres, of which William Hadley died seized in 1802. He purchased the southerly part, about one hundred and fifty acres extending up to the line of the Manor of Phillijjsburgh, from James Yan Cortiandt, in 1761, and the remainder froiii the Commissioners of Forfeiture, May 18, 1786. He lived in the old stone house yet standing on this tract, just west of the post road. Joseph Delaficld purchased the farm from Hadley's executors in 1829, and it is now owned by Delafield's children and grandchildren. The residence of Maturin L. Delafield is on the west side of Riverdale Avenue. The house of the late Lewis L. Delafield stands on the brow of the hill overlooking the Hudson.
