LESSON XL.

As a fitting close to the practical lessons embodied in this volume, we introduce one of the most radical departures in steam engineering, and one of the most successful of the almost numberless candidates working in the direction of high speed. This engine is, to a certain extent, an anomaly, and in Volume IL, which will complete this work, we hope to embody the valves and valve motion, and the regulator with its full line of action, so that our readers, who do not become discouraged in this volume, can gather from them what has been attained by a careful keeping in view of the theoretical value of steam after it is made, and the practical working out of the largest percentage of that theoretical value, which has, as yet, we believe, been attained by any high speed engine.

Figs. 82, 83, and 84, were all taken from the Armington & Sims engine, .on the same day, under varying conditions. The size of the engine was 9}^ inches diameter of piston, 12 inches stroke, 300 revolutions per minute, boiler pressure varying from 85 to 82 pounds, scale 60.
