Coal-Mine Accidents in the United States and Foreign Countries
From Introduction: "The lack of comparable and accurate statistics of coal-mine accidents in the united States as a whole led the Bureau of Mines in 1911 to undertake the collection of such data. The mining departments of the leading foreign coal-producing countries have long taken cognizance of the importance of statistics. The bureau feels that in presenting the tables embodied in this report it is offering the and comparable statistics of coal-min accidents for the country as a whole that have ever been published."

Recovery of Zinc from Low-Grade and Complex Ores
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."

North Dakota Lignite as a Fuel for Power-Plant Boilers
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: "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."
