Operating Details of Gas Producers

Description: From Introduction: "During the early years of these plants little success was anticipated from the use of bituminous coals and lignites, but in 1904 and 1905 it was fully demonstrated at Government testing station at St. Louis that these fuels could be utilized to excellent advantage. However, although many producer-gas plants in daily operation are still skeptical regarding the successful commercial use of these fuels."

The Origin of Coal

Description: From Introduction: "The purpose of the studies that form the basis of this report was to learn from microscopic examinations of coal how far and in what ways the grouping of coal by types depends on differences in the kinds of plant material from which it was formed and on the conditions of its accumulation, or how far the special characters or qualities of coal of any type were determined by the nature and the state of the plate debris from which the coal was formed."

A Primer on Explosives for Coal Miners

Description: From Introduction: "Much of the information in this primer has been obtained from experiments conducted by the technologic branch of the United Sates Geological Survey at the mining experiment station at Pittsburgh, Pa. These investigations have shown the recent development of a new type of short-flame explosives, which can be used with greater safety than black powder in mines where there is dangerous gas or inflammable dust, because the flame from the explosion of black powder lasts from 2,50… more
