Potash Mining in Germany and France

Description: From Scope of Bulletin: "This paper is confined largely to a discussion of methods of mining potash salts in France and Germany, in view of the possible application of similar methods when mining of the deposits in the southwestern part if the United States is undertaken, but it also includes a brief history of the German and French potash industry, a discussion of the geology of the deposits, a short description of the refining of crude salts for export, and an estimate of the cost of production."

Stone Dusting or Rock Dusting to Prevent Coal-Dust Explosions, as Practiced in Great Britain and France

Description: From Introduction: "Coal dust as an agent of widespread explosions had been under suspicion, and watering to allay the dust was recommended by some mining engineers but the watering of coal-mine dust was adopted in comparatively few mines of the United States and Great Britain, and had not been introduced widely in any country except Germany. Rock dusting, another method of preventing explosions of coal dust, was early tested with success by the Bureau of Mines in its first gallery at Pittsburgh and, beginning in 1911, at the experimental mine, Bruceton, Pa."
