The response to this appeal was the gathering at Jackson, on a bright mid-summer day, of hundreds of influential men from all parts of Michigan, representing every shade of anti-slavery feeling, and thoroughly alive to the importance of the occasion and the difficulty of the task projected. The convention far outstripped in numbers the preparations for its accommodation, and, after filling to excess the largest hall in the town, it adjourned to meet in a beautiful oak grove, situated between the village and the county race-course, on a tract of land then known as "Morgan's Forty." The growth of Jackson has since covered this historic ground with buildings, and the spacious grove has dwindled to a few scattered oaks shading the city's busy streets. A rude platform erected for speakers was appropriated by the officers of the convention, and about it thronged a mass of earnest men, the vanguard of the Republican host. In a body so incongruous and unwieldy, confused purposes, discordant views, and conflicting interests were unavoidable, but the universal fervor of the fusion sentiment formed a broad foundation for harmonious action, and the convention did not lack for shrewd and sagacious political managers with the skill to direct earnest effort into practical channels. Such differences of opinion as there were on questions of policy and as to candidates exhausted themselves in private conferences and secret committee deliberations, and the convention itself did its business with promptness, without discord, and amid a genuine enthusiasm. Its temporary chairman was the Hon. Levi Baxter, of Jonesville, a pioneer settler of Southern Michigan, and the founder of a family of marked prominence in that State. He was well known as the master spirit of many important business enterprises, had been a Whig and then a Free Soiler, and had been elected to the State Senate by a local coalition of both those parties in his own county. After a brief address by Mr. Baxter, Jeremiah Van Renselaer was chosen temporary secretary, and this committee on permanent organization was appointed: Samuel Barstow, C. H. Van Cleeck, Isaac P. Christiancy, G. W. Burchard, Lovell Moore, James W. Hill, Henry W. Lord, and Newell Avery. While they were deliberating, the convention adjourned to the oak grove, and there listened to brief speeches until a permanent organization was effected with the following gentlemen as officers of the first Republican State convention ever held: President--David S. Walbridge, of Kalamazoo. Vice-Presidents--F. C. Beaman, Oliver Johnson, Rudolph Diepenbeck, Thomas Curtis, C. T. Gorham, Pliny Power, Emanuel Mann, Charles Draper, George Winslow, Norman Little, John McKinney, W. W. Murphy. Secretaries--J. Van Renselaer, J. F. Conover, A. B. Turner.
