The U. S. Bureau of Mines, although one of the youngest 

 of the Government scientific bureaus, has published more than 

 130 bulletins and about the same number of "Technical Papers." 

 Many of these, as would be expected, are of interest chiefly 

 to persons engaged in the exploitation of coal, oil and gas, and 

 metalliferous deposits. A list of publications can be obtained 

 on application to Van H. Manning, Director of the Bureau of 

 Mines, Washington. Among reports of general interest are 

 the following: 



9. U. S. Bureau of Mines, Bulletin 38, 1913. The Origin of Coal. 

 By David White and Reinhardt Theissen, with a chapter on the 

 formation of peat by C. A. Davis. Sold by the Superintendent of 

 Documents, Washington, for SO cents.
