Upon the partition of Cortlandt's manor in 1734, the lots (included in this town) fell in the following order to the devisees and heirs of Stephanus van Cortlandt, viz., one-half of south lot No. 7, east of the Croton, to Stephen van Cortlandt ; ditto No. 8, Gertrude' Beeckman ; ditto No. 9, Margaret Bayard ; ditto No. 10, Mr. Skinner. The above lots have been long since distributed among numerous grantees, such as the Meads, Keelers, Rockwells, Ferrises, and Bowtons, &c., <fcc.
The general surface of Lewisborough is hilly and even mountainous ; much attention, however, has been paid to the improvement of the soil, which consists of clay mixed with a sandy loam. The whole township is well irrigated. Croton river runs along the nort'h-west corner while Cross river (the outlet of Lake Wacabuck) waters the central portion. Tatomuck river also rises within its limits; each of these streams supply numerous mill seats.
Upon the high hills which rise to the east of Cross river (near the eastern border of the town,) is situated the village of South Salem. This place contains several scattered dwellings, two stores, a post-office, (first established in March, 1813,) and a Presbyterian church.
The scenery of the neighborhood is uncommonly beautiful, aboundii]g in rich woods, deep valleys, and fertile pastures. The air also of its mountainous regions is said to be very salubrious. An opening through the hills to the south-west affords a fine view of the distant stony mountains, and the great valley of Cross river.
