[J. Thomas Scharf (1886)] MOUNT PLEASANT. 2sr> the Crotou River, as well as of the present Cort-landt township line, is an oak-tree by a rock oppo-site the north end of Deer Island, this having been ad-judged by the Commissioners of Forfeitures to be J" two miles from the mouth of the Croton River." The new township of Ossining having been taken out of Mount Pleasant in 1845, the boundary of Mount Pleasant along the old manor line was, of course, materially shortened, the new northwest cor-ner being where the Pocantico River crosses the old manor line. With this corner as a new starting-point, Mount Pleasant runs southerly along the Pocantico, River as far as Buckhout's Bridge, and over it. The line then strikes directly westward to the Hudson -River, at the point where the dividing line of prop-erty between the land of the late Rev. William Creighton, D.D., and the land of the late Abraham;Leggett comes to its western terminus by meeting the waters of the Hudson. This line was newly run out in August, 1884, by Messrs. Ward Carpenter & Son, surveyors and civil engineers, so well known in Westchester County for their painstaking accuracy, with a view to determine what part of the new aqueduct, now in process of construction, lay within the township of Mount Pleasant, and what in Ossining. It was found, on making the survey, that St. Mary's Church, Beech-wood, which had previously been supposed to be within the limits of Mount Pleasant, was really in the township of Ossining.
