Nothing of a useful nature grew out of Herosspeculations, and it was not until the seventeenthcentury that the practical value of steam for pur-poses of carriage assumed tangible form. In 1680Newton sought to invent a machine by which 2 Vol 1 18 RAIL ^YA Y EQ UIPMENT. the reactionary force of steam upon the airwould propel the vehicle forward. His experi-ments, however, were not satisfactory. In 1769Cugnot, an officer of the French army, invented asteam-propelled vehicle with three wheels. Thefront supported a frame which carried a steamboiler and other appliances. The machine wassteered by a lever from the platform. The driv-ing wheel was of wood; it was tired with iron,and about four feet in diameter. Cugnot is saidto have been the first to apply the high pressure.

The first attempt to utilize steam forpropelling carriages in America was made byNathan Read of Salem, Massachusetts, in is credited with having constructed the firstmultitubular boiler. The tubes were placed ver-tically. The forward wheels of the machine wereplaced on a swiveling axle, operated by a hand EVOLUTION OF LOCOMOTIVE.
