TECHNOLOGY.— Reports issued by the Bureau of Mines: 



Coals available for the manufacture of illuminating gas. A. H. White and Perry 

 Barker. Bulletin 6, pp. 77. 1911. Results of experiments with 6 typical 

 coals. Gives analyses of the coals and the percentages of gas, ammoniacal 

 liquor, etc., obtained by distilling in a standard horizontal retort. 



Resume of producer -gas investigations, October 31, 1904, to June 30, 1910. R. H. 

 Fernald and C. D. Smith. Bulletin 13, pp. 393. 1911. A detailed account 

 of results obtained in gas-producer tests made by the United States Geologi- 

 cal Survey. Gives analyses of producer gas from different classes of coals. 

 Discusses the chemical reactions involved in the gasification of fuel in a pro- 

 ducer and the factors that affect the economical operation of a gas-producer 

 plant. 



Investigation of the explosives used in coal mining, with a chapter on the natural gas 

 used at Pittsburgh. Clarence Hall, W. O. Snelling, S. P. Howell andG. A. 

 Burrell. Bulletin 15, pp. 197. 1912. Discusses the nature, composition and 

 thermochemistry of explosives, with particular reference to permissible 

 explosives. Among the subjects considered are the thermochemistry of 

 carbon dioxide and carbon monoxide, the formation of carbon dioxide and 

 carbon monoxide in the presence of water, the maximum temperature of 

 explosion of various explosive substances; the specific heats of solid sub- 

 stances at high temperatures; practical methods of reducing the flame 

 temperatures of explosives; and tables of use in thermochemical calculations.
