From introduction: This survey was the first systematic work undertaken in this geologic province since the Geological Exploration of the Fortieth Parallel, in 1869, and was the first detailed geologic examination of a wide area in the Wasatch Range. Hence, an unusual amount of general geologic work in the region surrounding the special field was required to establish fundamental geologic facts.

Report describing the geology of Long Island based on surveys and research conducted 1903-1905, with a particular emphasis on glacial deposits and formations from the Pleistocene epoch. It includes a broad discussion, with tabular summaries.

From introduction: This is the most current attempt to locate all the mining districts of the western states.

Report issued by the Bureau of Mines over studies conducted on fuel-testing plants. The results of steaming tests on coals are presented and discussed. This report includes tables, illustrations, and photographs.

From Preface: "The present bulletin is printed as a supplement to Bulletin 17 and is intended primarily for coal miners, especially for those working in fields where inflammable gas or coal dust may cause disastrous mine explosions. The bulletin is issued by the Bureau of Mines in the hope that it may prove helpful in lessening accidents due to the use of explosives, and in particular may aid in preventing mine explosions, many of which have been caused by the use of improper explosives."

From Introduction: "In connection with the fuel investigations conducted by the Bureau of Mines much information has been accumulated as to the smoke abatement activities in various cities. The essential features of the information are presented in this report, which, it is believed, will be of public interest and benefit, especially to those communities that are just beginning organized effort to abate unnecessary smoke."

From Results of Briquetting Tests: "The results of the briquetting investigations conducted by the Government are expected to prove of considerable value, not only to the Government itself as the owner of extensive lignite deposits and largest single purchaser of fuel, but also to the people living in the the regions where lignite is found. The problem assumes still larger proportions when one realizes that the development of manufacturing industries in those regions depends upon the ability to obtain a cheap and satisfactory fuel. Although the results presented in this bulletin are not conclusive, they warrant the continuation of the investigators as soon as funds can be available for the purpose."

Report concerning the rise in the usage of coal and the growing pollution of coal smoke. Includes the ordinances of several cities that arose to combat this pollution.

From Introduction: "Under the terms of the act establishing the Bureau of Mines, this bureau was authorized to carry on the work of testing and analyzing fuels which had been conducted by the technologic branch of the United States Geological Survey. Therefore, the first investigations of the liquid mineral fuels logically embraced a careful series of comparative tests of gasoline and denatured alcohol in engines. The report is published by the Bureau of Mines because of the transfer of the fuel-testing investigations to this bureau."

From Introduction: "The tests described in the following report were made by the United States Geological Survey in cooperation with the United States Reclamation Service, which, in connection with its Williston project, had erected a large pumping plant at Williston, N. Dak., and had installed steam boilers with furnaces designed to burn a "brown lignite" that was mined on adjacent government land. The results of the tests made at Williston, set forth in this report, show that this fuel, through generally considered unsatisfactory, may be used with fair economy under boilers that generate their full rated capacity."

From Introduction Scope of Report: "This bulletin is a report on an investigation of the volatile matter in several typical coals-its composition and amount at different temperatures of volatilization. As the investigation is still in progress and will doubtless include other coals than those already examined, the bulletin may be considered a preliminary report, stating the problems studied, the methods used, and the results thus far obtained."

From Introduction: "This bulletin deals with washing and coking tests of coal made at the Government fuel-testing plant in Denver, Colo., between July 1, 1908, and June 30, 1909."

Bulletin issued by the U.S. Bureau of Mines regarding the conditions of the mines beneath the city of Scranton, Pennsylvania, including suggestions about methods to continue excavating coal while preserving the structural integrity of the city's foundation.

Technical paper issued by the Bureau of Mines over studies conducted on the constituents of coal. As stated in the introduction, "this paper presents some results of an investigation of the nature of the chemical compounds that go to make up the complex material known as coal" (p. 5). This report includes tables and a chart.
