Thus had been established two splendid fast trains, and the outlook was bright for the future, when Congress, in spite of the efforts of the Post-Office Department, passed an Act reducing the already inadequate compensation to the trunk lines, for the carrying of the mails. This action brought official notice from Messrs. Vanderbilt and Scott of the discontinuance of the fast mail trains between New York City and Chicago, and that service ended. [Illustration: At a Way-station--The Postmaster's Assistant.] Colonel Bangs was greatly mortified at this result, but he stood his ground and remained at his post until the close of the year. Then, worn out with never-ending toil, and disheartened by the action of Congress, he tendered his resignation and insisted on its acceptance. Parted from the Post-Office, President Grant, knowing his worth and wishing to recognize his services, appointed him Assistant Treasurer of the United States at Chicago. He lived to perform the duties of this office only a few months, as death overtook him suddenly, while on a visit to Washington on official business, December, 1876. His work, however, was not permitted to drop. He had left in the service three assistants, Theodore N. Vail, William B. Thompson--afterward Second Assistant Postmaster-General--and John Jameson, who were fully imbued with the ideas of their late chief and were fully loyal to them. They, in the order named, became his successors, and never permitted opportunities to escape wherein there was a possible benefit to the service to be secured. Although the fast mail service was suspended for lack of support from Congress, its usefulness and practicability had been so thoroughly demonstrated that an appropriation of $150,000 was made in March, 1877, for its resumption on the trunk lines. This victory was not reached without untiring efforts on the part of Mr. Vail, and by generous support in both houses of Congress; in the Senate by the Hon. Hannibal Hamlin and James G. Blaine, of Maine, and in the House of Representatives by such broad and liberal statesmen as Mr. Waddell, of North Carolina, Mr. Randall, of Pennsylvania, and Mr. Cox, of New York. Since then, Messrs. Thompson and Jameson have watched the progress of the work with jealous eyes, and have succeeded in extending it practically to the whole country. The present service is due not alone to the liberality of Congress, because the appropriations have been parsimonious, but to the generosity of the railways, which have performed a valuable work for a price which in many cases does not pay the expense of the necessary additional labor involved.
