. Factory and industrial management. e engines wasstopped by Watt, as they infringed his patent on the separate condenser. more than a year in Europe, he again discusses the use of the com-pound engine and conckides by saying: In the face of these facts, further discussion on the suliject of engine for the vessels of our own navy is as useless as the discussion of the relative merits of the screw propeller and paddlewheel for ships of war. The compound engines which were in use had demonstrated verythoroughly that they possessed a marked economy over the simpleengines immediately preceding them, but in spite of this there wasconsiderable opposition to the general introduction of the compoundengine. This came from two sources. One was in naval circles andwas represented by certain reactionary but influential executive officerswho feared that the danger of boiler explosion would be greatly in-creased by the use of the higher pressures which were necessary with ECONOMY IN MARINE ENGINEERING. 47. JONATHAN of the Compound Engine. the compound engine. Theyforgot that with rehable mate-rial and proper design the high-pressure boiler was just as safeand worked with the same mar-gin as the boiler of lower pres-sure. They also forgot that asfar as damage due to the scald-ing effect of the steam is con-cerned, low-pressure steam wasjust as bad as high. As a matterof fact, it may be remarked inci-dentally that there is not a caseon record of a well designedand carefully built high-pres-sure boiler ever having ex-ploded. It has been surmisedthat some steamers which werelost at sea without anythingbeing known as to the cause were blown up, but there is no ground forthis belief, particularly as thousands of boilers have worn out withoutever giving trouble on this score. The other class of objectors, curiously enough, included engineerswho made some pretension to scientific attainments, and some of themindeed were men of the very hi
