"In 1809, he was called to Dartmouth College, where for one year he was Professor of Languages, and was then transferred to the professorship of Mathematics, Natural Philosophy, and Astronomy, which he held until the appointment of a successor, in 1833. As a teacher he was faithful, patient, laborious, earnestly desiring the best good of his pupils, whose affection he often succeeded in gaining, their esteem always. Possessed of much intellectual force, of sound and varied attainments in learning, which he had the happy faculty of imparting to others clearly and distinctly, he was thus eminently fitted for the position of instructor, so many years occupied by him. He was truly devoted to the interests of the college, and ever ready to make efforts and sacrifices for it, and in those dark days, when its fate hung in suspense, he was deeply anxious, and had no small share in aiding and sustaining it through the struggle. During President Brown's illness, and after his death, for more than two years in all, he filled the office of president in addition to his own, thus having a great increase of care and responsibility, and the same thing occurred on other occasions, when the college was temporarily without a head. He did not enjoy the situation, for while he truly delighted in teaching, he found the enforcement of discipline very irksome; still he was faithful and energetic in it when it became his duty. "He was interested in every good cause, philanthropic and religious, especially in the Bible Society, of which he was for many years the presiding officer in New Hampshire; in the Colonization Society, which he then thought the only possible agency for removing the curse of Slavery; in Foreign Missions and in Temperance, of which he was an earnest and able advocate. In this connection it should be mentioned that he was Trustee and Treasurer of Kimball Union Academy, at Meriden, almost from its first commencement until nearly the close of his life, and in the success end prosperity of that institution he always felt a deep interest, and labored to promote its welfare.
