Report issued by the Bureau of Mines over the Salt Flat fields in East Central Texas. As stated in the introduction, "this report deals with the development and production history of the Salt Flat field and gives comparative data on five outstanding fault fields. Two of these fields are producing from limestone and three from sandstone reservoirs" (p. 2-3). This report includes tables, maps, photographs, and illustrations.

Report compiled by the U.S. Bureau of Mines including statistics on fatalities in coal mines located in the United States as well as data regarding the various operations (e.g., number of miners employed and average production). The information is organized into tables for comparison and the text draws some overall conclusions in the summary.

Report issued by the U.S. Bureau of Mines covering accidents that happened in metal mines located in the United States including statistics for injuries, fatalities, kinds and causes of accidents, and operational data, such as number of mine workers and shifts worked.

From Introduction: "The results of this preliminary investigation, which were reported to the association at the 1928 convention, indicated, first, that fundamental information on the mechanism of carbonization throughout the entire range from low to high temperature coking is desired and, second, that a uniform basis upon which to compare the carbonizing properties of different coals should be developed."

From Forward: "This paper gives the details of tests to determine the design of stoppings capable of withstanding a pressure, applied to either side, of 50 pounds per square inch, as required by section 104 (a) of the Operating Regulations to Govern Coal-Mining Methods on Leased Lands on the Public Domain, issued in 1921 and quoted on page 3."

From Introduction: "The methods of making the physical tests of explosives recorded here are based upon the results of more than 20 years of experience of the staff of the explosives division of the Bureau of Mines at the Pittsburgh testing station and at its successor, the Explosives Experiment Station, Bruceton, Pa. The methods are described in unusual detail to permit repetition that will duplicate, as nearly as possible, the precise manner in which they have been performed in the past and to reduce differences in technique to a minimum."

From Introduction: "Material for this report was gathered during the last quarter of 1928 and the first quarter of 1929, when the author visited the quick-silver-producing districts of California, Nevada, Texas, Oregon, Washington and Arizona to view the progress made in recent years and gather material for a comprehensive study of the present-day quicksilver industry of the United States."

Report discussing testing of coals in Pierce County, Washington. The investigation had three parts: a geological survey of the coal property, washing and crushing tests of the coals, and coking and by-product tests.

From Content and Arrangement of Report: "For the convenience of the reader the bulletin has been divided into two parts. Part I describes the investigation and summarizes the most important results. Part II gives the detailed data of the best of the washing tests by each process."

Report published by the U.S. Bureau of Mines which is a compilation of accidents in quarries located in the United States with data regarding the number and kinds of accidents as well as information about the mining operations (e.g., number of men employed, kinds of quarries, amount of work performed, etc.).

From Basis and Purpose of Report: "This report constitutes a large-size sample of these causes as taken from the Pennsylvania Department of Mine records. This report should therefore be a valuable experience record for all those who seek to prevent accidents with explosives, especially to all users of explosives."
