Papin invented in 1698 a carriage that was fitted with a steam engine as such is now understood; that is, a cylinder and a piston. This was probably the first vehicle of its kind known in Europe. The construction was a model merely, a toy which ran around the room, but it is said to have worked well. Concerning this invention, Papin said: "I believe that one might use this invention for other things besides raising water. I have made a little model of a carriage that is propelled by this force. I have in mind what I can do, but I believe that the unevenness and turns of the highway will make this invention very difficult to perfect for carriages or road use." Although encouraged to prosecute his work by the Baron Gottfried Wilhelm von Leibnitz, his doubts could not be overcome in regard to the practicability of his proposed carriage. He still claimed, however, that by the aid of such vehicles, infantry could probably be moved as quickly as cavalry and without the necessity of heavy impedimenta of food and other supplies. VAUCAUSON A celebrated French mechanician, Vaucauson, in April, 1740, built a vehicle "to go without horses." He was visited at his palace in Rue Charonne, Paris, by King Louis Fifteenth, and the exhibition of this vehicle, which, according to reports, was propelled by a "simple watch spring," was reviewed in a journal of the time as follows: "Yesterday, at 3 P.M. His Majesty, accompanied by several officers and high court functionaries, repaired to the palace of M. Vaucauson and took his seat on a species of throne specially prepared for his reception on a raised platform, whence he could clearly discern all the mechanism of the carriage in its gyrations through the avenues and alleys. The vehicle would seat two persons, and was painted scarlet, bordered in blue, ornamented with much gilding; the axle trees of the wheels were provided with brakes and set in motion by a fifth wheel, likewise well braked and bound with long ribbons of indented steel. Two chains communicated with a revolving lever in the hands of the conductor, who could at will start or stop the carriage without need of horses. His Majesty congratulated the skillful mechanician, ordering from him for his own use a similar vehicle to grace the royal stables. The Duke of Montemar, the Baron of Avenac and the Count of Bauzun, who had witnessed the trial, were unable to credit their own vision, so marvelous did the invention appear to them. Nevertheless, several members of the French Academy united in declaring that such a piece of mechanism could never circulate freely through the streets of any city." Either from royal forgetfulness or thanks to the customary court intrigues to turn His Majesty from his purpose, or possibly because of the somewhat crude nature of the invention itself, the fact is that from that time forth not the slightest mention is to be found in history of the motor carriage of Vaucauson.
