As stated in the introduction, "the report is part of a series by the Bureau of Mines, a series of analytical and statistical reports on the mineral resources of foreign countries. The report is based on published material and other information on the general geology and the general economic conditions of Iran" (p. 2). This report includes maps, tables, illustrations, and photographs.

From Abstract: "This Bulletin presents, in collected and tabulated form, Bureau of Mines (Pittsburgh station) data pertaining to the plastic, agglutinating, and free-swelling characteristics of American coals."

Report issued by the Bureau of Mines over studies conducted on the compounds of coal carbonization. Descriptions of these compounds are discussed. This report includes tables.

Report issued by the Bureau of Mines over drilling and sampling of the San Manuel copper mine in Arizona. Properties of the drill samples are presented. This report includes tables, maps, and illustrations.

From Introduction: "This Bureau of Mines bulletin was prepared to compile in readily usable form the heat content, heat-of-formation, and free-energy-of-formation data for 65 common elements and their respective oxides, halides, carbides, and nitrides. The bulletin was prepared to encourage the application of thermodynamics in the metallurgical field; consequently, the values have been presented in a simple, readily usable form and several examples of their applications have been shown."
