WHERE The mechanical equivalent of heat as we have had frehermal unit—that unit being the quantity of heat neces ary to raise one pound o f water one degree in temperature lowever frequently we may present it. A pound of pure carbon yields in burning 14500 units )f heat equivalent to 14500 X772=194000 foot pounds of energy. A pound of good coal containing 91 per cent :arbon as shown in the report of the committee of the Amer can Institute testing steam boilers in 1872 produces about 3200 units of heat and its mechanical equivalent is 3200 X 772-10190400 foot-pounds of work. The very best classes of modern steam engines very seldom onsume less than two pounds of coal per horse power per lour and it is a good engine that works regularly on three munds. A horse power raises 1980000 pounds one foot ugh per hour. Consequently a pound of coal in our very lest engines developes but taa 2_o_a a-990000f oot pounds nstead of the 10190400 which it would give us were there to loss of power. The first-class steam engine therefore yields less than 10 I )er cent of the work stored up in good fuel and the averge engine probably utilizes less than 4 per cent. A part of this loss is unavoidable being due to natural ther portion is to a considerable extent controllable by the :ngiueer or by the engine driver. Scientific research has shown that the proportion of heat tored up in any fluid which may be utilized
