A history of the growth of the steam-engine . de Saxe, heconstructed his first steam locomotive-engine, which onlydisappointed him, as he stated, in consequence of the ineffi-ciency of the feed-pumps. The second was that built underthe authority of the Minister Choiseul, and cost 20, 000livres. Cugnot received from the French Government apension of 600 livres. He died in 1804, at the age of sev-enty-nine years. Watt, at a very early period, proposed to apply his own STEAM-LOCOMOTION ON BAILEOADS. 153 engine to locomotion, and contemplated using either a non-condensing engine or an air-surface condenser. He actuallyincluded the locomotive-engine in his patent of 1784; andhis assistant, Murdoch, in the same year, made a working-model locomotive (Fig. 45), which was capable of ninningat a rapid rate. This model, now deposited in the PatentMuseum at South Kensington, London, - had a flue-boiler, and its steam-cylinder was three-fourths of an inch in diam-eter, and the stroke of piston 2 inches. The diiving-wheelswere 9^ inches diameter.. Fia. 45.—MnrdocVs Model, 1T84. Nothing was, however, done on a larger scale by eitherWatt or Murdoch, who both found more than enough toclaim their attention in the construction and introductionof other engines. Murdochs model is said to have runfrom 6 to 8 miles an hour, its little driving-wheels makingfrom 200 to 275 revolutions per minute. As is seen in thesketch, this model was fitted with the same form of engine, known as the grasshopper-engine, which was used in theUnited States by Oliver Evans. To Oliver Evans, says Dr. Ernest Alban, the distin-guished German engineer, was it reserved to show the truevalue of a long-known principle, and to establish thereon anew and more simple method of applying the power ofsteam—a method that will remain an eternal memorial to 154 THE MODERN STEAM-ENGINE. its introducer. Dr. Alban here refers to the earliest per-manently successful introduction of the non-condensinghigh-pressure steam-engine. O
