It is said that flocks of them used to fly from the Yonkers ridge on the west side of Tippet's brook to this hill, at certain seasons of the year, for the purpose of feeding on the acorn and beech nut. The flight was always commenced by a large black cock of the woods, sunset being the signal for departure; the leader gave the well known note, and they were instantly on the wing for the opposite hills. There yet remains a fine specimen of the ancient denizens of the forests on the western edge of this hill, by the roadside leading to the village. This venerable chestnut tree, in the Fall of the year, appears to be the favorite gathering place of thousands of swallows just before they commence their migrations.

At the commencement of the Revolutionary War this hill was rented by two grand-sons of the first proprietor, Thomas and Gilbert Valentine, who occupied it through the whole course of the war. In the summer of i775> the American army threw up entrenchments on its summit, the remains of which are still visible. When his Excellency General Washington lay encamped on Valentine's hill in the Fall of 1776, it was supposed to be the design of the enemy to attack his position.
