The United States Senate Committee on Transportation Routes to the Seaboard, was a Senate committee, initially authorized by Senate resolution as a select committee on December 16, 1872. The select committee, also known as the Windom Select Committee for its first chairman, William Windom, submitted their significant report regarding current rail and water transportation on April 24, 1874; it was ordered to be printed the same day. The committee became a standing committee on March 19, 1879, with little documented activity, and continued to exist until 1921.
Originally composed of seven members, it was enlarged to nine on March 26, 1873, during the special session of the Senate held after March 4; the Committee underwent further personnel changes the following year and was ultimately composed of William Windom, of Minnesota; John Sherman, of Ohio; Roscoe Conkling, of New York; J. Rodman West, of Louisiana; Simon B. Conover, of Florida; John H. Mitchell, of Oregon; Thomas M. Norwood, of Georgia; Henry G. Davis, of West Virginia; and John W. Johnston, of Virginia. When enlarged, the Senate adopted a resolution authorizing the Committee to sit at such places as they might designate during the recess and to investigate and report upon the subject of transportation between the inferior and the seaboard; it also authorized the Committee to employ a staff and provided for actual and necessary expenses attending such investigation upon vouchers approved by the chairman.
The Committee visited various portions of the country and collected a mass of useful information relating to rail and water transportation in the United States at the time. Viewing the movement toward developing the inland waterways of the country, 35 years later in 1908, the Inland Waterways Commission considered the select committee's report the third epoch in this movement, but notes, "although the plans and recommendations of Senator (and Secretary) Windom and his colleagues received less attention than was anticipated, of course by reason of the rapid growth of interest in railways." It goes no to say: "Perhaps the most notable result, albeit rather an indirect than a direct one, appeared in the improvement of the Passes at the mouth of the Mississippi with the development of navigation in that river through the Eads jetty system, which opened an era in river control by engineering devices. The Windom report, too, is of both historic and practical interest, although the appended matter pertaining to special localities and passing conditions is of less value."
