This principle was afterward applied to cars, and nearlyall the rolling-stock in this country is now constructed on this plan,which was proposed by Mr. Allen in a report dated May 16, 1831,made to the South Carolina Canal & Railroad Company ; and anengine constructed on this principle was completed the same year. In the latter part of the year 1831 the late John B. Jervis in-vented what he called a new plan of frame, with a bearing-carriagefor a locomotive eneine, for the use of the Mohawk & HudsonRailroad. Jerviss engine is shown by Figure 9. In a letter. Fig. 8.—The Planet. io8 AMERICAN LOCOMOTIVES AND CARS.
