" The County of Westchester comprises a very important section of this State; washed on the west by the Hudson, on the south by the East River and Long Island Sound, it enjoys very superior advantages for trade and commerce, with a fine soil for agriculture, and a charming diversity of surface and of elegant situation ; while its contiguity to the great commercial metropolis of North America, completes a proud superiority of geographical position. The north-west corner is considerably broken by the south-east border of the Highlands, of a mountain character; and a range of hills of moderate height extends from York Island toward the north-east extremity, on which are situated the heights and hills much known in the Revolutionary war, particularly in the year 1776. Besides Harlem, Hudson and East Rivers, forming the boundaries, there are several small streams that afford many mill seats.

INTRODUCTION.

Peckskill Creek and Croton River, which rise in Dutchess and Putnam counties, run south westward across the north western part of Westchester County to the Hudson. Saw Mill River runs from Mount Pleasant to the Hudson at Yonkers; and Bronx River, the largest, Hutchinson's and Mamaroneck Rivers run south into the East River. Byram River runs from Westchester, principally in Connecticut, and forms two miles of the State boundary from its mouth in East River, which receives some other small streams from the south-east angle of Westchester County, direct across the south-west angle of Connecticut."
