Structure in Paleozoic Bituminous Coals

Description: From Introduction: "To fill in a few of these gaps and to clarify some of the existing confusion is the aim of this paper. The immediate cause that led the author to investigate further the composition of coal and the origin and structure of its constituents was that when an attempt was made to discover the meaning of the coking and noncoking properties of a coal a more exact knowledge of the nature of the coal was required than was then available."

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

Description: 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."

Coals Available for the Manufacture of Illuminating Gas

Description: From Introduction General Statement: "The investigations were so directed as to permit the testing of coals from different parts of the united States. The results show that certain coals from which good yields of gas had been expected can not be considered as available for illuminating-gas manufacture, whereas other coals give promise and should investigated further. The data contained in this report are the outcome of the cooperative work at the laboratory mentioned during parts of the years 1908 and 1909."

Coals of Chile

Description: From Introduction: "The purpose of this investigation was to determine whether the coal from beds mined in the Schwager and Lota mines will produce metallurgical coke suitable for use in the blast furnaces at the proposed steel plant at Conception, and whether the quality of the lower-rank coals from other areas in Chile, especially those in Magallanes, where the large coal reserves of Chile appear to exist; can be improved by processing."

Carbonizing Properties: Chilton Coal from Lorado Number 5 Mine, Lorado, Logan County, West Virginia

Description: From Forward: "The value of this survey of the carbonizing properties of American coals by a standard method lies in the comparability of the results on different coals. A secondary objective of the Bureau of Mines carbonization studies is to obtain information on the chemical and physical properties of different coals that may effect the yield and nature of the gas, coke, and byproducts."

Carbonizing Properties: Pocahontas Number 6, Davy Sewell, and Fire Creek Coals from West Virginia and Upper and Lower Kittanning and Upper and Lower Freeport Coals from Pennsylvania

Description: From Forward: "The value of this survey of the carbonizing properties of American coals by a standard method lies in the comparability of the results on different coals. It must recognized that no standard laboratory method of carbonization, even on a large unit, can yield results that exactly duplicate those obtained in ovens and retorts. The commercial results vary with the type of oven or retort. Allowance must be made for such differences in interpreting the BM-AGA test results in terms of commercial plants."
