Of the forty fields into which the farm was divided, Jay kept a separate account: showing the tillage and produce, the drainage and fencing, the dates of planting and reaping. A volume of this kind, begun in 1816, contained entries as late as 1857, the year before his death. He perfected himself in grafting and budding, and was particularly successful with peaches, with cherries, pears and plums, some of them with Huguenot names and memories, and with muskmelons from Persian seed, brought to him from the East by a friend. He raised horses from imported stock, Merino sheep, and superintended the curing of hams from a Westphalian recipe, furnished by an old Hessian farm hand--one of the hirelings who had come to conquer and remained to cultivate the country. In 1818 Jay and Fenimore Cooper drafted the constitution for an agricultural society of which Governor Jay was the first president and General Pierre van Cortlandt the second--an institution of great use in the development of Westchester County. In 1815, when twenty-six years of age, Jay entered upon that course of active philanthropy which for the next forty years employed his thoughts and pen. His first effort was directed to the improvement of his native town of Bedford in the organization of the Society for the Suppression of Vice. By means of this society, of which he was the secretary, he did much to restrain the liquor traffic and to diminish intemperance. Later on, as a judge, he used all the power of the law to the same end; and it was he who suggested the law, still in force, which forbids a tavern-keeper to supply drink on credit.
