Input: Question: How much was Alford purchased for? Passage:Timothy Woodbridge (February 27, 1709 – May 10, 1774) was an American missionary, deacon and schoolteacher, later a judge, representative, and Superintendent of Indian Affairs, from Springfield, Massachusetts, who spent most of his adult life in Stockbridge, Massachusetts, teaching the Mahicans and other Native Americans to read and write, English customs and the Christian religion. About him, Jonathan Edwards said, "By his long-proved justice and integrity, he has gained a vast esteem with the Indians". Reverend John Sergeant described his efforts in this way: "Mr. Woodbridge ... has a very numerous school and a tedious task of it; lives a very lonesome life; is indeed indefatigable in his business; and no body deserves more of the publick than he." Gideon Hawley called him "a man of abilities... always poor, and had a powerful party against him; but he rose to be the first man in the county." Timothy worked very closely with all three men. He was instrumental in the purchase of large tracts of land in western New England from the Native Americans, such as modern-day Lenox and Alford, Massachusetts, by parlaying this reputation and experience.
