A history of the growth of the steam-engine . —to construct a steam-carriage, or fiery chaiiot, as he 150 THE MODERN STEAM-ENGINE. poetically styled it, and of which he sketched a set of young man named Edgeworth became interested inthe scheme, and, in 1768, published a paper which had se-cured for him a gold medal from the Society of Arts. Inthis paper he proposed railroads on which the carriageswere to be drawn by horses, or by ropes from steam-wind-ing engines. Nathan Read, of whom an account will be given here-after, when describing his attempt to introduce steam-navi-gation, planned, and in 1790 obtained a patent for, a steam-carriage, of which the sketch seen in Fig. 43 is copied fromthe rough drawing accompanying his application. In thefigure, A A A A are the wheels ; B B, pinions on the hubsof the rear wheels, which are driven by a ratchet an-ange-ment on the racks, G G, connected with the piston-rods;C o is the boiler ; D D, the steam-pipes carrying steam tothe steam-cylinder, EE; FFaxQ the engine-frames ; S is.

Read made a model steam-carriage, which he exhibitedwhen endeavoring to secure assistance in furtherance of hisschemes, but seems to have given more attention to steam-navigation, and nothing was ever accomplished by him inthis direction. These were merely promising schemes, however. Thefirst actual experiment was made, as is supposed, by aFrench army-officer, Nicholas Joseph Cugnot, who in1769 built a steam-carria
