Two days were consumed in organizing and adopting the platform. The second night of the Convention, that which intervened between Thursday and Friday, was given up to remarkable exertions in behalf of the several candidates. William H. Seward, of New York, was the most prominent candidate before the Convention, and would probably have been named had the nominations been made on the first or second day of the Convention. The other candidates were Abraham Lincoln, of Illinois; Simon Cameron, of Pennsylvania; Salmon P. Chase and John McLean, of Ohio; Edward Bates, of Missouri; William L. Dayton, of New Jersey, and Jacob Collamer, of Vermont. There was a strong opposition to Mr. Seward, based on the ground of his availability, as it was felt by Henry S. Lane, of Indiana, and A. G. Curtin, of Pennsylvania, who were the candidates for Governor in their respective States, that Mr. Seward could not carry those States. Mr. Greeley was also doing his utmost to defeat Mr. Seward, but was advocating the nomination of Edward Bates, of Missouri. The Illinois delegation had been instructed for Mr. Lincoln, and soon added Indiana to his support, and they also obtained promises of a majority vote of the New Hampshire, Virginia and Kentucky delegations on the first ballot, with some scattering votes from other States. Mr. Lincoln's candidacy was very promising, but not entirely certain of success, as, to many, the strength of Mr. Seward appeared invincible; but Mr. Lincoln's supporters were certain that if he could obtain a good vote on the first ballot it would be largely increased on the second ballot by votes from Pennsylvania, Ohio and Vermont. On the third day of the Convention, Friday morning, May 18th, the nominations were made. William M. Evarts presented the name of William H. Seward, and was immediately followed by Norman B. Judd, of Illinois, who nominated Mr. Lincoln. Others were named, and a number of seconding speeches were made, Mr. Lincoln's name being seconded by Caleb B. Smith, of Indiana, and Columbus Delano, of Ohio. The cheers and noisy enthusiasm which attended the various speeches were terrifying in volume, and it was apparent that the Lincoln shouters had the advantage in volume of sound, and the influence of the vast assemblage and the great pressure of environment unquestionably increased Mr. Lincoln's chances for the nomination. The balloting began and proceeded amid intense excitement; two hundred and thirty-three votes were necessary to a choice, and three ballots were taken, with the following result: 1st 2d 3d Ballot. Ballot. Ballot. Seward ......... 173½ 184½ 180 Lincoln ........ 102 181 231½ Cameron ........ 50½ 2 Chase .......... 49 42½ 24½ Bates .......... 48 35 22 Dayton ......... 14 10 McLean ......... 12 8 5 Collamer ....... 10
