This report is descriptive of various methods used in the kiln drying of woods for airplanes and gives the results of physical tests on different types of woods after being dried by the various kiln-drying methods.

Report presenting the Miner's Safety and Health Almanac, which contains a calendar and information on diseases that may affect miners and their families. Some more common causes of accidents in mines and show how the miner can lessen the risks of their work.

This is a report on the copper deposits of Ray and Miami, Arizona.

A collection of writings on the shorter contributions to general geology.

Introduction: In the following pages a number of selected analyses or tests of the oil and gas from this field are given, with such descriptions of the analytical methods used as are necessary to an understanding of the results.

Introduction: The interpretation of the data furnished by the study of these fossils has been hindered somewhat because the exact stratigraphic location of much of the material is unknown. It was gathered with regard merely for the general stratigraphic and geographic position. However, as a knowledge of the general relationship forms to those of other areas is in itself of value to the stratigrapher and systematist it has seemed desirable to describe and figure the species.

introduction: The present paper, which in some respects is supplementary to another recent one on the same region, is based on a series of vertebrate remains collected during the field season of 1916 for the United States Geological Survey by J.B. Reeside, jr., and F.R. Clark.

Report issued by the Bureau of Mines over the eleven experiment stations established near important mining fields. The work done by the stations are discussed. This report includes tables, illustrations, and photographs.

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 introduction: The purpose of the field work was to investigate the geology of the county, particularly the structure or lay of the oil-bearing strata and the results of drilling to date. Structural conditions in the producing fields were determined by running level lines to the wells and correlating the data recorded in the well logs generously furnished by the operators.

This report describes the results of expeditions to map the geologic and topographic features of the Kantishna region of Alaska.

A handwritten document addressed to the members of the First Quarterly Conference (presumably of St. Paul's Church), reporting greater than normal church attendance and with the spiritual condition of the church described as unusually good. The document also expresses a need for a deep awakening and a new sense of God in Christ, and lists the names of 45 people who have recently been added to the church.

A handwritten document addressed to the Second Quarterly Conference of St. Paul's Church. The document contains financial information, a report on growth, information on new members and members who have left, and future plans.

Report describing a newly discovered type of oyster in the Texas Cretaceous stratigraphical zone.

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."

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).

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."
