Government Coal Purchases Under Specifications with Analyses for the Fiscal Year 1909-10,

Description: From Introduction: "This bulletin is the fourth of a series showing the results of the purchase of coal by the Government under specifications. The work of inspecting and analyzing coal delivered on Government contracts was transferred to the Bureau of Mines by an act of Congress effective July 1, 1910. It had been carried on for several years before that date by the technologic branch of the United States Geological Survey. The purpose of this paper is to explain in general terms the methods that the Government has found most satisfactory for the purchase of a large part of its coal supply, including the consideration of bids, the awarding of contracts, and the analyzing of samples on which the price corrections are based."

Fuel-Briquetting Investigations, July, 1904, to July, 1912

Description: Report discussing a series of fuel-testing investigations that U.S. Geological Survey began in 1904 for the purpose of analyzing and testing the coals and lignites in the United States in order to determine their fuel values and the most efficient methods of utilizing them for different purposes. Types of tests undertaken included chemical analyses, steaming tests, gas-producer tests, briquetting tests, coking tests, and washing tests of samples collected from the various coals fields of the country. Bulletins presenting the results of these investigations have been periodically published but as supply has run out, the Bureau of Mines has decided to compile the most important facts of these bulletins in one volume along with the results of all other briquetting investigatins undertaken by the government from July 1, 1904, to July 1, 1912.
