Coal Mining in Europe: A Study of Practices in Different Coal Formations and Under Various Economic and Regulatory Conditions Compared with Those in the United States

Description: From Introduction: "The major purpose of this bulletin, as indicated in the preface by Dr. John W. Finch, Director of the Bureau of Mines, is to give a critical review of the coal-mining methods used in the principal producing countries of Europe, to describe the reasons underlying the adoption of these methods, and to contrast them with coal-mining methods employed in the United States."

Commercial Possibilities of the Texas-New Mexico Potash Deposits

Description: From Introduction Results of Test: "Among the domestic potash resources which were brought to the attention of the country during and after the war but were not utilized as a source of potash, although they indicated that they might furnish the cheap potash desired, were the potash deposits occurring with the think rock-salt formations of western Texas and southeastern New Mexico."

Contributions to the Data on Theoretical Metallurgy: [Part] 1. The Entropies of Inorganic Substances

Description: From Introduction: "The present work is an attempt to collect all the available data referring to one important thermodynamic property and to supply sufficient discussion to make the results readily usable by metallurgists. In the study of chemical or metallurgical reactions two factors have predominant importance-the free energy of reaction and the speed of reaction. The subject of this publication is so closely allied to the former that may be well to consider briefly some of the uses to which free-energy data may be put."

Contributions to the Data on Theoretical Metallurgy: [Part] 3. The Free Energies of Vaporization and Vapor Pressures of Inorganic Substances

Description: From Introduction: "It is the purpose of this present work (1) to apply the previously compiled entropy values and specific-heat equations to vapor-pressure and other pertinent data in obtaining heat and free energy of vaporization equations for inorganic substances valid up to the normal boiling or sublimation points (760 mm pressure), (2) to supplement wherever possible the data on heats and entropies of transformations and fusions, (3) to supplement wherever possible the data on heats and entropies of gases, and (4) to supply tables of vapor pressures for inorganic substances at various temperatures up to and including the boiling or sublimation point."
