ALCOHOL 



its Manufacture 

 Its Denaturization 

 Its Industrial Use 



The Cost of Manufacturing Denaturized Alcohol in Germany and 

 German Methods of Denaturization 



are discussed by Consul-General Frank H. Mason in Scientific American 

 Supplement 1550. 



The Use, Cost and Efficiency of Alcohol as a Fuel for Gas Engines 



are ably explained by H. Diederichs in Scientific American Supple- 

 ment 1596. Many clear diagrams accompany the text. The article con- 

 siders the fuel value and physical properties of alcohol, and gives details 

 of the alcohol engine wherever they may be different from those of a 

 gasoline or crude oil motor. 



The Production of Industrial Alcohol and 

 Its Use in Explosive Motors 



are treated at length in Scientific American Supplement 1581, valuable 

 statistics being given of the cost of manufacturing alcohol from farm products 

 and using it in engines. 



French Methods of Denaturization 



constitute the subject of a good article published in Scientific American 

 Supplement 1599. 



How Industrial Alcohol is Made and Used 



is told very fully and clearly in No. 3, Vol. 95, of the Scientific American. 



The Most Complete Treatise on the 

 Modern Manufacture of Alcohol 



explaining thoroughly the chemical principles which underlie the process, 

 without too many wearisome technical phrases, and describing and illustrating 

 all the apparatus required in an alcohol plant is published in Scientific Amer- 

 ican Supplements 1603, 1604 and 1605. The article is by L. Baudry de 

 Saunier, the well-known t rench authority. 



In Supplements 1607, 1608 and 1609 we publish a digest of the rules 

 and regulations under which the United States Internal Revenue will permit 

 the manufacture and denaturization of tax-free alcohol.

Boilers 



All rooms, floors, nooks and corners are uni- 

 formly warmed to the solid com.fort of little 

 and big folks. Five months wir ter still ahead! 

 Need not remove old heating methods until 

 ready to start fire in the new. 



ADVANTAGE: IDEAL Boilers are of low construc- 

 tion, which admits them into the most shallow cel- 

 lars. (Buildings without cellars can also be heated.) 

 A strong feature of this low construction is the am- 

 ple opportunity given to run the mains, or large 

 supply pipes, at such decided pitch in the cellar as 

 to thoroughly drain the Steam system of the water 

 of condensation or to insure rapid circulation in a 

 Hot Water system. This makes a better working 

 job and removes any liability of " trapping " and its 

 resultant uncouth, gurgling noises, commonly 

 termed "pounding in the pipes." The IDEAL way 

 is gentle, steady, noiseless
