Postmaster-generals up to the period when railroads superseded that of post-coaches and post-horses had a much harder time in their “vocation” than have their successors since. The difficulties then were to overcome the opposition of parties interested in contracts. Coaches and post-horses, routes and agents, became important items in such contracts; and the least favoritism on the part of the postmaster-general called forth not only censure from those immediately interested, but not unfrequently from those high in authority. During the postal administration of W. T. Barry, Esq., considerable political feeling was mixed up with these complaints. Mails at that period (1835) were carried on horseback from central points, and by four-horse post-coaches from city to city. Lines of stages were established in several sections of our country. The number of post-offices was 10,693. The line of stages extended to the western boundary of Missouri; to St. Augustine, in Florida; through Indiana, by the seat of government in that State; through the whole Territory of Michigan and State of Illinois; from Detroit to Chicago; and from Chicago to St. Louis, in Missouri; thence to New Orleans, in half the time which it formerly occupied. This facility, however, was afforded by connecting the coaches with steamboats in the mail-transportation. Lines of post-coaches were also established in this year from Nashville to Memphis, on the Mississippi River, in Tennessee; from Tuscumbia in Alabama to Natchez in Mississippi; and to Tuscaloosa, the seat of government in Alabama; and from Tuscaloosa to Montgomery; completing a direct line from Nashville in Tennessee, and all the other Western States, to the city of New Orleans. A semi-weekly line of two-horse stages was added to a tri-weekly line of four-horse post-coaches from Washington City, through Lynchburg in Virginia, Salisbury, N.C., Yorkville, S.C., and Augusta, to Savannah in Georgia; from thence to the northern part of Georgia, through that State to Tallahassee, and to Pensacola in Florida. We have given this statement for the purpose of showing the amount of labor essential to the transportation of the mails at that period, compared to what it is now. It is, however, somewhat strange that railroads were not established in many places, which would have obviated the necessity of coaches. _SOMETHING ABOUT RAILROADS._ Railroads, although evidently of ancient origin, were first used near Newcastle-upon-Tyne, in 1650. Wooden rails four to eight inches square, resting upon transverse sleepers two feet apart, were in use for many years, when railroads of the same description covered with thin plates of iron were substituted.
