The Mining Industry in the Territory of Alaska: During the Calendar Year 1916

From Introduction: "The year 1916 broke all previous records of mineral production in the Territory. As a consequence, there has been a noteworthy increase in the number of mines in active operation or under development, though the greater part of the increased output is the result of greater activity at mines already producing rather than of opening new mines.The Territorial inspector covered the districts from Fairbanks to Nome and the Federal Inspector covered those of southeastern and southwestern Alaska."

From Introduction: "A critical study of the wet Thiogen process for extracting sulphur from smoke of smelters is one of several investigations related to the general smelter-smoke problem that are being conducted under direction of the Bureau of Mines. Work on the Thiogen process was started again in January, 1916, in the laboratories of the new mining experiment station at Berkeley, Cal., and was continued during the spring of 2016 until a point was reached where it was felt that the essential parts of the process had been carefully covered, and that some definite statements concerning the technical features and possibilities of the process, as given in this report, were warranted."
