Analyses of Coals in the United States with Descriptions of Mine and Field Samples Collected between July 1, 1904 and June 30, 1910: Part 1. -- Analyses
From Significance and value of Analyses of Coal: "The analyses published in this report cover samples of coal collected in many different parts of the country with unusual care by experiences men, in such manner as to make them representative of extensive beds of coal."
Analyses of Coals in the United States with Descriptions of Mine and Field Samples Collected between July 1, 1904 and June 30, 1910 Part 2. Descriptions of Samples
From Introduction: "This volume contains the descriptions of the samples whose analyses are published in the preceding volume, Part I of this bulletin. The descriptions have been compiled from the notebooks of the persons who collected the samples, have been condensed from accounts given in published reports of the United States Geological Survey, or have furnished by the collection themselves. Inasmuch as the descriptions represent the work of many persons during a period of six years, and inasmuch as they were recorded under widely differing conditions, they necessarily vary in fullness detail."
Analyses of Washington Coals: Supplement to Technical Papers 491 and 618
From Washington Coalfields: The geographical distribution of the principal coal areas of Washington is shown in figure 1. Detailed information concerning these fields is given in Bureau of Mines Technical Paper 491. Further information on the minor coal areas is given in two bulletins of the Washington Division of Mines and Geology. Analyses, plastic properties, free-swelling indexes, and agglutinating values of the separate coals, together with data on yields of carbonization products and properties of the cokes produced in laboratory tests and under operating conditions."
Approximate Quantitative Microscopy of Pulverized Ores, Including the Use of the Camera Lucida
Technical paper issued by the Bureau of Mines over microscopy of pulverized ores. As stated in the introduction, "this paper, which deals with the study of pulverized ores and the use of the camera lucida in such work, discusses an investigation undertaken at the Seattle and the Golden mining experiment stations of the Bureau of Mines" (p. 3). This paper includes tables, illustrations, and photographs.
Burning Washington Coals on Different Types of Domestic Stokers in the Same Hot-Water Boiler: Comparison with Hand and Oil Firing
From Purpose and Scope: "This bulletin presents the results of an investigation of domestic stokers at the Northwest Experiment Station of the Bureau of Mines. Previous publications have dealt with the burning characteristics of Washington coals on a domestic overfeed stoker, a clinker-type domestic underfeed stoker, and an ash-removal-type domestic underfeed stoker designed for burning anthracite. This report includes all the principal results obtained on the three domestic stokers tested and compares these results with those obtained on the same hot-water boiler by hand-firing and oil-firing."
City Smoke Ordinances and Smoke Abatement
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."
Coal-Mining Problems in the State of Washington
From Introduction: "On account of extensive folding and faulting of the coal measures, mining in Washington presents many difficulties; therefore a description of the methods employed at some of the mines may be useful in planning operations in other regions, and is presented in this bulletin."
