A dark blue plate with a rose and fruit border. In the exact centre of the plate is the Court-House in an open square. Pedestrians are walking to and fro. The design of this plate is very stiff and ugly. The mark on the back is a scroll of blue, with words “Baltimore Court-House;” also a circular impressed mark, smaller than the Clews mark, with words “Warranted Staffordshire.” 140. Baltimore & Ohio Railroad. Wood. Plates printed in dark blue with rich shell border, with a train of little cars like stage-coaches, and the stumpy little locomotive which it is said was designed by Peter Cooper, and which was originally intended to have sails like a boat to help propel it along. The corner-stone of this railroad was laid in Baltimore, July 4, 1828, by Charles Carroll of Carrollton, the last surviving signer of the Declaration of Independence. This event was considered of so great importance that it was celebrated by a great trades-procession in Baltimore, during which the cordwainers made a fine pair of satin shoes which were at once sent to the idolized Lafayette, and were placed in the museum at La Grange. In 1830 the first locomotive was placed on the road. Peter Cooper thus describes it: “The engine was a very small and insignificant affair. It was made at a time when I had become the owner of all the land now belonging to the Canton Company, the value of which, I believe, depended almost entirely upon the success of the Baltimore & Ohio Railroad. When I had completed the engine I invited the directors to witness an experiment. Some thirty-six persons entered one of the passenger cars, and four rode on the locomotive, which carried its own fuel and water; and made the first passage of thirteen miles over an average ascending grade of eighteen feet to the mile, in one hour and twelve minutes. We made the return trip in fifty-seven minutes.” The locomotive on these blue plates is not like the Tom Thumb locomotive in an old print which I possess; it is more like the “Stourbridge Lion,” the first engine made in England for America, which arrived in New York in 1829. Marks on plate both E. Wood and Wood. 141. Baltimore & Ohio Railroad. Down Hill. This plate is in dark blue with a shell border. It has a stationary engine at the top of a hill, with a number of small freight cars running down a very steep grade, with the cars at a very singular angle. Both Baltimore & Ohio plates are here shown.
