Bulletin issued by the U.S. Bureau of Mines: "This publication is devoted exclusively to a review and abstracts of decisions based on the laws governing the rights and duties of mine owners, operators, miners, and persons trafficking in all kinds of mining properties. It includes abstracts of current decisions of all the Federal and State courts of last resort on questions relating to the mining industries" (Bulletin 61, p. 9).

Report issued by the Bureau of Mines over investigations conducted on common war minerals. Descriptions of the minerals and their uses are presented.

Report issued by the Bureau of Mines over studies conducted on petroleum and helium production. The results of the studies are presented and discussed.

From General Statement Purpose of the Report: "The present investigation was undertaken for the purpose of supplying some of the material so badly needed in the valuation and more efficient operation of oil properties. Because of the lack of time for further studies, the amount of data already accumulated and the policy of the Bureau of Mines of publishing as soon as possible any information that may be of use to an industry, the bulletin is issued now."

From General Statement: "Beginning with an investigation to develop the best type of gas mask, the scope of the work extended until it included researches relating to a wide range of devices, such as different types of poisonous and irritating gases and smokes, smoke screens, gas shells and gas bombs, signal lights, and incendiary bombs. When the results obtained through this research were to be applied by the War Department, the Director of the Bureau of Mines cooperated in the selection of men to have charge of manufacture or further development, recommending chemists who subsequently received commissions in the Army. Perhaps the greatest result of the research work has been the demonstration of the value of the services that the chemist and chemical engineer can render in time of need and the recognition of chemical investigations as a necessary function of the Government."

It includes abstracts of current decisions of all the Federal and State courts of last resort on questions relating to the mining industries" (Bulletin 61, p. 9).

From Introduction: " This bibliography follows the same general scheme as the bibliography of petroleum and allied substances for 1915. References to articles in these journals have been taken from such sources as were available and credit has been given to those sources. American and foreign patents have been entered by title, without abstracts. A few minor changes have been made in the scheme of classification, which is, on the whole, the same is given in the 1915 bibliography."

From Introduction: "The bulletin aims to give the localities of the various mining districts, and the nature of the present operations and those that have been carried out in the past."

From Introduction: "Vocalization in retorts has been, until recently, the only commercial process of producing spelter, hence the zinc mine operators have had to meet the terms of the zinc mine operators have had to meet the terms of the zinc smelters in regard to the following requirements: (1) Minimum percentage of zinc the ore must contain; (2) the chemical combination of the zinc in the ore; (3) the proportion present of those elements that interfere with the successful recovery of the zinc when the ore is retorted. As stated previously, and as will be shown later, a large part of the valuable mineral content of the ore is lost in effecting this concentration. As a result of the other requirements that have to be met in zinc smelting, much zinc is lost in the mining and milling of zinc ore."

From Introduction: "This report gives the results of a study conducted by the Bureau of Mines for the purpose of informing the petroleum industry on the recent progress in the development and application of the absorption process for recovering gasoline from natural gas."

From Introduction: "The purpose of this bulletin is to describe the methods of constructing and operating representative types in the United States used for removing the light hydrocarbons from petroleum by continuous distillation, such plants being commonly known in the trade as topping or skimming plants."

From Introduction: "This report on the electrodeposition of gold and silver from cyanide solutions represents work that has occupied my time at intervals during the past 20 years, The investigations has been carried on simultaneously with my duties as professor of mining and metallurgy of the University of California."

From Introduction: "The report presents statistical data compiled from various sources, showing the production of gold in the United States and other countries, with comparative figures for coal, iron, and other mineral products, and describes the sources and distribution of gold output in the United States."
