Molybdenum; Its Ores and their Concentration with a Discussion of Markets, Prices, and Uses
From Scope and Purpose of Investigation: "The direct purpose of the bulletin is, on the one hand, to prove to possible consumers of molybdenum that the element is not as rare as commonly supposed, and that this country possesses many deposits of low-grade ore from which large supplies may be derived, and on the other hand, to prove to present and prospective producers of molybdenum that there is a latent market for their product in the alloy-steel trade, which needs only the assurance of steady supplies for a considerable development."

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."

Oil and Gas Wells through Workable Coal Beds: Papers and Discussions
From Preface: "In carrying out such a policy with reference to the subject under consideration, the Bureau of Mines invited the State geologists, mine inspectors, and a number of coal operators and oil and gas well drillers from the States interested to meet representatives of the Bureau of Mines in Pittsburgh, Pa., for a discussion of the subject during February 7 and February 8, 1913. This adjourned meeting of the conference will be held at an early date and its report will be printed in a later edition of this bulletin, with such additional suggestions as may be received by the Bureau of Mines. The bureau will be glad, therefore, to receive at the earliest practicable date any additional suggestions or any additional information throwing light on the matters discussed in this bulletin."

The Wet Thiogen Process for Recovering Sulphur from Sulphur Dioxide in Smelter Gases: A Critical Study
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."

The Use of Mud-Laden Fluid in Oil and Gas Wells
From Introduction: "Technical Paper 66 deals with the mud-laden fluid process in general and No. 68 with its application in Oklahoma. Rather than reprint these publications, it has been considered advisable to replace them with the present report, which includes the results of more recent investigations. The methods of using mud-laden fluid are an outgrowth of the rotary drilling system, which was developed in Texas and later employed in Louisiana and California."
