In 1844 Mr. Greeley worked with tremendous intensity for the election of Henry Clay, but to no purpose. In February, 1845, the Tribune office was thoroughly burnt out, but fortunately with no serious loss. The paper was throughout completely opposed to the Mexican War. In 1848, and subsequently, the paper at first with hopeful enthusiasm and at last with sorrow chronicled the outbreak, progress and fate of the great Republican uprising in Europe. During the same year Mr. Greeley served a three months' term in Congress, signalizing himself by a persistent series of attacks both in the House and in his paper, on the existing practice in computing and paying mileage--a comparatively petty swindle, mean enough doubtless, in itself, but very far from being the national evil most prominently requiring a remedy. This proceeding made Mr. Greeley a number of enemies, gained him some inefficient approbations, and did not cure the evil. In 1857 he went to Europe, to see the "Crystal Palace" or World's Fair at London, in that year. He was a member of one of the "juries" which distributed premiums on that occasion; investigated industrial life in England with some care; and gave some significant and influential information about newspaper matters, in testifying before a parliamentary committee on the repeal of certain oppressive taxes on newspapers. He made a short trip to France and Italy; and on his return home, reaching the dock at New York about 6 A. M., he had already made up the matter for an "extra," while on board the steamer. He rushed at once to the office, seizing the opportunity to "beat" the other morning papers, by an "exclusive" extra, sent off for the compositors, who had all gone to bed at their homes; began setting up the matter himself; worked away along with the rest until his exclusive extra was all ready, and then departed contentedly to his own home. Mr. Greeley had always been a natural abolitionist; but, with most of the Whig party, he had been willing to allow the question of slavery to remain in a secondary position for a long time. He was however a willing, early, vigorous and useful member of the Republican party, when that party became an unavoidable national necessity, as the exponent of Freedom. With that party he labored hard during the Fremont campaign, through the times of the Kansas wars, and for the election of Mr. Lincoln. When the Rebellion broke out he stood by the nation to the best of his ability, and if he gave mistaken counsels at any time, his mistakes were the unavoidable results of his mental organization, and not in the least due to any conscious swerving from principle, either in ethics or in politics.
