exerted his influence in founding an association for familiar written and oral discussions in literature, in which Dr. Edward Oliver, Dr. James Marsh, Professor Fiske, Mr. Rufus Choate, Professor Chamberlain, and others, acted a prominent part. He retained this chair until August, 1838, when he was appointed to that of Intellectual Philosophy and Political Economy, which he now holds, but, which, of course, will be occupied by another during his absence in the public service--the faculty having declined on any account to accept his resignation or to appoint a successor. Dr. Haddock has been invited to the professorship of rhetoric in Hamilton College, and to the presidency of that institution, the presidency and a professorship in the Auburn Theological Seminary, the presidency of Bowdoin College, and, less formally, to that of several other colleges in New England. In public affairs, he has for four successive years been a representative in the New Hampshire Legislature, and in this period was active in introducing the present common school system of the State, and was the first commissioner of common schools, originating the course of action in that important office which has since been pursued. He was one of the fathers of the railroad system in New Hampshire, and his various speeches had the effect to change the policy of the State on this subject. He addressed the first convention called at Lebanon to consider the practicability of a road across the State, and afterward a similar convention at Montpelier. For two years he lectured every Sabbath evening to the students and to the people of the village, on the historical portions of the New Testament. For several years he held weekly meetings for the interpretation of Scripture, in which the ladies of the village met at his house. And for twenty years he has constantly preached to vacant parishes in the vicinity. He has delivered anniversary orations before the Phi Beta Kappa Societies of Dartmouth and Yale, the Rhetorical Societies of Andover and Bangor, the Religious Society of the University of Vermont, the New Hampshire Historical Society, and the New England Society of New York; numerous lyceum lectures, in Boston, Lowell, Salem, Portsmouth, Manchester, New Bedford, and other places; and of the New Hampshire Education Society he was twelve or fifteen years secretary, publishing annual reports. The principal periodicals to which he has contributed are the _Biblical Repository_ and the _Bibliotheca Sacra_. A volume of his _Addresses and Miscellaneous Writings_ was published in 1846, and he has now a work on rhetoric in preparation. He has been twice married--the last time to a sister of Mr. Kimball, the author of "St. Leger," &c. He has three children living, and has buried seven.
