Assuming,' that nlfohol can lio put on tho market at tlio same jn-ico as gasoline, 

 he is ai)Ie to coniimte the heat cost, as sliown in the following table: 



Relative heat cost of alcohol, gasoline, and kerosene. 



From German tests the following table of economy and cost figures is collated : 

 Relative economtj of alcohol, etc. {German data). 



From these figures the author concludes that at the present time, with 90 per 

 cent alcohol at 15 cts.. the operation with alcohol would cost about 19 per cent 

 more than with gasoline and about 22 per cent more than with kerosene. The 

 advantage of gasoline from the standi)oint of fuel cost is, however, said to be 

 less than the other advantages in favor of the alcohol engine, which accounts 

 for its extended application in European countries. 



Free alcohol in the arts and as fuel, C. Baskerville {Amer. Mo. Rev. of. 

 Revieics, 5-} (1900), Xo. 199, pp. 211-21Jt). — A brief discussion of the uses of 

 alcohol, its manufacture and denaturization, with certain economic and social 

 conditions likely to result from the removal of the tax upon the denaturized 

 product. 



The alcohol law and its relation to American industry, D. A. Willey 

 (Tnidcsntuii. .JJ (19(16). Xo. .9, p. -ll). — The writer reviews the status of the 

 alcohol industry in France and Germany and makes some predictions as to its 

 future in this country under the " alcohol law." 



It is held that alcohol can l)e distilled from corn at a total expense of less 

 than 12 cts. per gallon, and from refuse of molasses, beets, and sugar cane at 

 about 10 cts. per gallon. As an instance of the industrial development which 

 will result from the use of grain alcohol, the author mentions one large imple- 

 ment firm which has enlarged its plant purposely for making gas engines so 

 that it will be able to build no less than 20,000 a year. "The indications are 

 that fuel stations for distrilaiting alcohol will be located throughout the United 

 States, just as petroleum tanks are now situated." The writer thinks " the 

 advantages to the South and West from the use of alcohol are especially notable, 

 since these sections produce such an enormous quantity of corn, potatoes, and 

 beets, together with refuse molasses from sugar manufacture." 



Firing boilers with vegetable fuels, M. RI^GEr.MA^'N (.Jour. Agr. Prat., n. 

 ser.. 12 (1906), Xo. 2S, pp. .'/6-.50). — In this article means are described for 

 utilizing as a fuel peat, wood, tree branches, bark, sawdust, dry weeds, straw, 

 sugar-cane stalks, etc. The quantities of each necessary per horsepower hour 

 are given, and special types of furnaces adapted for such fuels are illustrated 

 and described.
