Gas-Lift Method of Flowing Oil Wells: (California Practice)
From Introduction: "In this report the author has presented data of actual gas-lift operations in the oil fields of California. Wherever theoretical hypotheses and conclusions are given an attempt has been made to support them by field data gathered during consultation with engineers and operators. The impossibility of drawing conclusions that will apply to all wells or even to one well throughout its life is appreciated by everyone who has studied the subject, and the reader is cautioned not to accept all the data presented as being applicable to every well."

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."
