After their marriage and romantic honeymoon, they installed themselves in a home on Lexington Avenue where the charm of her voice and the grace of her manner with his genius as a host and prince of hospitality drew about them a delightful coterie of interesting people, particularly those distinguished in arts, music, letters, and social life in New York City. During the Civil War, Mr. Arthur served on the staff of Governor E. D. Morgan, of New York City, as engineer in chief. He was later made Inspector General, and in January, 1862, was promoted to the position of Quartermaster General. His task in equipping thousands of volunteers was arduous and difficult, and brought him much praise for the businesslike efficiency with which it was conducted. His war account, notwithstanding its length, owing to the great number of men equipped, was the first audited, and that without the reduction of one dollar, while those of other states were cut in varying amounts ranging from one million to ten million dollars. He made it a rule to accept neither gifts nor favours, though many handsome presents were sent him, and he was poorer at the close of this service than before the term began. He was also inspector of New York troops in the field on the staff of Major General Hunt, of the Army of the Potomac. After the war, he resumed his law practice with great success, gaining a national reputation through the important legal cases he handled, and was for a time counsel to the Board of Tax Commissioners, who paid him a salary of $10,000 a year. He received the appointment of Collector of the Port of New York in 1871 from President Grant, and his reappointment in 1875 was confirmed by the Senate. Hayes selected for Secretary of Treasury John Sherman, “who deemed it important that the custom-house appointments should be in the hands of one more friendly to the Hayes administration than Mr. Arthur.” Theodore Roosevelt was appointed collector, but the United States Senate refused to confirm the appointment, and Arthur and Cornell held their respective offices until adjournment of Congress, July 11, 1878, when they were suspended. Arthur had previously declined to resign, as requested by Secretary Sherman, notwithstanding the fact that he was promised a foreign mission. His friends prepared and circulated a petition for his reinstatement which carried the signature of every judge of every court of New York City, of all important members of the bar, and of three fourths of the merchant importers. When Mr. Arthur learned of this, he refused to permit it to be presented.
