The National Convention of the Republican party that met at Chicago, in June, 1880, will always be marked with a red-letter in the annals of our country. The third-term issue, the unit rule, district representation, and the arbitrary power of party managers, made the nomination for President one long scene of hard fought battles. The three prominent candidates were General Grant; James G. Blaine, Senator from Maine; and John Sherman, Secretary of the Treasury. The third-term party who desired the nomination of Grant, was strongly supported by Senator Conkling of New York, Senator Cameron of Pennsylvania, and Senator Logan of Illinois. These three great political leaders are thus described by a graphic writer, who was present at the opening of the Convention:-- "Just as the great Exposition Building had nearly filled up, there was a simultaneous huzza throughout the hall and galleries, and it speedily broke out in a hearty applause. The tall and now silvered plume of Conkling was visible in the aisle, and he strode down to his place at the head of his delegation with the majesty of an emperor. He recognized the compliment by a modest bow, without lifting his eyes to the audience, and took his seat as serenely as if on a picnic and holiday. The Grant men seemed to be more comfortable when they found him by their side and evidently ready for the conflict. "Logan's swarthy features, flowing mustache, and Indian hair, were next visible on the eastern aisle, but he stepped to the head of his delegation so quietly that he escaped a special welcome. He sat as if in sober reflection for a few moments, and then hastened over to Conkling to perfect their counsel on the eve of battle. The two senatorial leaders held close conference until the bustle about the chair gave notice that the opposing lines were about to begin to feel each other, and test their position. "Cameron had just stepped upon the platform with the elasticity of a boy, and his youthful, but strongly-marked face was recognized at once. There was no applause. They all knew that he never plays for the galleries, and that cheers are wasted upon him. He quietly sat down for ten minutes, although the time for calling the convention to order had passed by an hour, and looked calmly out upon the body so big with destiny for himself and his Grant associates. As he passed by he was asked,-- "'What of the battle?' "'We have three hundred to start with,' he replied, 'and we will work on till we win.' "This was said with all the determination that his positive manner and expression could add to language, and it summed up his whole strategy." George F. Hoar, from Massachusetts, was appointed President of the Convention; and among the delegates from Ohio, and enthusiastic supporters of Sherman, was General Garfield, thus described by a writer in the _Chicago Inter-Ocean_:--
