The Indiana delegation was strengthened on the Democratic side by the return of William E. Niblack, who had made a good record in the Thirty-seventh Congress, and by the entrance of Michael C. Kerr, who served for a long period and ultimately became Speaker of the House. Messrs. Julian, Orth, and Dumont were again elected. The last-named had made a reputation in the preceding Congress as a keen and able man. The Illinois delegation, which had contained a large majority of Democrats in the Thirty-eighth Congress, now returned strongly Republican,--Mr. Lincoln's victory of 1864 having, with three exceptions, carried with it every Congressional district. Four men of marked characteristics were among the new members of the delegation, one of whom was already widely known: the three others were destined to become so in different degrees--John Wentworth, Shelby M. Cullom, Burton C. Cook, and Jehu Baker. Wentworth had been in the House as a Democrat prior to the war, having represented the Chicago District continuously from March 4, 1843 to March 4, 1851; and again from March 4, 1853 to March 4, 1855. He was endowed by nature with a mind as strong as his body, and that was of Titanic proportions. He was an ardent partisan in behalf of any cause he espoused; was willful, aggressive, and dominating. He was, at the same time, genial and kindly in many relations of life, not without gifts of both wit and humor, and courageous to the point of absolute fearlessness. He had been well educated at Dartmouth College in his native State, and long practice had made him a dangerous antagonist in debate. He had been an intense Democrat, but he refused to join Douglas in the repeal of the Missouri Compromise, and subsequently united with the Republicans.--Shelby M. Cullom, with good natural parts and sound education, amiable, pleasing, and endowed with the gracious quality which attracts and holds friends, won his way promptly in the House and gave early promise of the success which afterwards elevated him to the governorship of Illinois, and thence transferred him to the Senate of the United States.--Burton C. Cook was recognized as an able lawyer from the beginning of his service. He constantly grew in influence and strength during the eight years of his continuous membership, and at its close returned to the bar with an enviable reputation and with the assurance of that eminent success which has since attended his professional career.--Jehu Baker was a man of peculiarities, not to say oddities, of bearing; but these did not conceal his worth and ability, nor retard the growing reputation which has since retained him in a diplomatic position.
