leaders of the Federalist party, as opposed to the Republicans or Democratic-Republicans. From 1821 until 1828 he was president of the American Bible Society. He died on the 17th of May 1829. The purity and integrity of his life are commemorated in a sentence by Daniel Webster: "When the spotless ermine of the judicial robe fell on John Jay, it touched nothing less spotless than itself." See _The Correspondence and Public Papers of John Jay_ (4 vols., New York, 1890-1893), edited by H. P. Johnston; William Jay, _Life of John Jay with Selections from his Correspondence and Miscellaneous Papers_ (2 vols., New York, 1833); William Whitelocke, _Life and Times of John Jay_ (New York, 1887); and George Pellew, _John Jay_ (Boston, 1890), in the "American Statesmen Series." John Jay's son, WILLIAM JAY (1789-1858), was born in New York City on the 16th of June 1789, graduated from Yale in 1807, and soon afterwards assumed the management of his father's large estate in Westchester county, N.Y. He was actively interested in peace, temperance and anti-slavery movements. He took a prominent part in 1816 in founding the American Bible Society; was a judge of Westchester county from 1818 to 1843, when he was removed from office by the party in power in New York, which hoped, by sacrificing an anti-slavery judge, to gain additional strength in the southern states; joined the American anti-slavery society in 1834, and held several important offices in this organization. In 1840, however, when it began to advocate measures which he deemed too radical, he withdrew his membership, but with his pen he continued his labours on behalf of the slave, urging emancipation in the district of Columbia and the exclusion of slavery from the Territories, though deprecating any attempt to interfere with slavery in the states. He was a member of the American peace society and was its president for several years. His pamphlet, _War and Peace: the Evils of the First with a Plan for Securing the Last_, advocating international arbitration, was published by the English Peace Society in 1842, and is said to have contributed to the promulgation, by the powers signing the Treaty of Paris in 1856, of a protocol expressing the wish that nations, before resorting to arms, should have recourse to the good offices of a friendly power. Among William Jay's other writings, the most important are _The Life of John Jay_ (2 vols., 1833) and a _Review of the Causes and Consequences of the Mexican War_ (1849). He died at Bedford on the 14th of October 1858. See Bayard Tuckerman, _William Jay and the Constitutional Movement for the Abolition of Slavery_ (New York, 1893).
