aA PRACTICAL HANDBOOK 



For Decorators, Paperhangers, Architects, Build- 

 ers and House Owners, with many half-tone and

Br ARTHUR SEYMOUR JENNINGS 



Extract from Preface 



T-'he author has endeavored to include char- 

 acteristic designs in vogue to-day, and to give 

 reliable information as to the choice of wall 

 papers as well as to describe the practical 

 methods of applying them. In dealing with 

 matters concerning decoration there is always 

 the danger of leaning too much toward an ideal 

 and of overlooking the practical requirements 

 of commercial life. The author hopes that he 

 has been successful in avoiding this fault, and 

 that his book will be regarded as both practical 

 and useful.

ALCOHOL 



ITS MANUFACTURE 

 ITS DENATURIZATION 

 ITS INDUSTRIAL USE 



The Cost of Manufacturing Denatur- 

 ized Alcohol in Germany and Ger- 

 man 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. Diedrichs in Scientific 

 American Supplement 1596. Many clear dia- 

 grams 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 

 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 pub- 

 lished in Scientific American Supplement 1599. 



l-low 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 Alco(>ol 



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 

 American Supplements 1603, 1604 and 1605. 

 The article is by L. Baudry de Saunier, the 

 well-known French authority. 



In Supplements 1607, 1608 and 1609_ we 

 publish a digest of the rules and regulations 

 under which the United States Internal Rev- 

 enue will permit the manufacture and dena- 

 turization of ta.x-free alcohol.
