Corsa knew personally every individual of that celebrated band of volunteers called the "Westchester Guides," of whom he himself was the last and youngest ; and he was among the most confidential friends of the heroic Abrahnm D^'ckman, who fell prematurely at the close of the revolutionaiy contest. Pussessed of a memory unusually retentive, and residing constantly upon the borders of tlie "neutral ground," he was acquainted with all the distinguished partisius both from above and below, and with nearly all the military operations wlietiier great or small that occurred along this portion of the British lines; and which, until %"t-ithin the last few days of his life, he continued to describe in minute detail.

Upon the conclusion of the revolutionary war, his father's lands, by a compulsory sale, passed out of the family ; and although without any means at the time, he did not hesitate to purchase, with monej' borrowed upon mortgage, a contiguous farm -- which industry and good management enabled him, not many years after, to disencumber. !5Iuch engaged in the cultivation of fruit for the market, he was particularly successful with the apple and pear; discovering and bringing into use a new variety of the latter which bears his name, being known distinctively as the Corsian Vergaloo.

For many years he was a member of the Reformed Dutch Church at Fordham. His death was preceded by none of the diseases to which humanity is heir, and he ceased to exist only because he was worn out by toil and time. The macliiue which had been set in motion by its divine constructor and which had gone on for more than four score years and ten, "at last stood still," and the weary occupant sought a better habitation. His memory continued miimpaired until nearly the close of his existence.
