Pursuant to this provision the line between Westchester and Putnam Counties starts on the Hudson at Anthony's Nose and follows an easterly course to the Connecticut boundary. The surface of the county consists of several ranges of hills, with valleys stretching between, in which are numerous streams and an abundance of lakes. None of the physical features of Westchester County (if we except its lovely prospect of the Hudson) are in any wise remarkable from tin1 viewpoint of the tourist in quest of natural wonders. On the other hand, its entire surface presents scenery of diversified beauty and interest, not the less gratifying to the contemplative eye because unchangeably modest in its pretensions. The principal chain of hills is the one closely bordering the Hudson, already noticed. This is the southern prolongation of the Highlands. Its elevations display a constant diminishing tendency southward. Another range, likewise extending north and south, is found near the Connecticut border. The Matteawan .Mountains enter the northwestern corner of the county, and thence cross the Hudson. A high ridge, called the Stone Hill (the watershed of tin- county), passes from the town of Mount Pleasant on the Hudson eastward through the towns of New Castle, Bedford, Pounolridge, and Salem into Connecticut, in spite of this exception, however, the general trend of the hills is north and south, a fact illustrated by the almost uniformly southerly course of the more considerable streams, and by the usually level character of the roads running north and south, as contrasted with the conspicuous unevenness of those which extend east ami west. Famous in our county's history are the North Castle or Chappaqua Hills, above White Plains, into which Washington retired with the Continental army after the engagement near the latter place (October 28, 1776), and, on account of the strength of the new position thus gained, compelled General Howe, with his greatly superior force, to return to New York.
