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."

From Introduction: "As a result of the recommendations of this committee, special studies have been made of the methane hazards incident to mining and tunneling operations in the Coast Range Mountains. These studies have resulted in the adoption of numerous safety precautionary measures; among them the use of permissible types of mining equipment, electric cap lamps, with which this deals with primarily."

From Introduction Purpose of Report: "The importance of safety work in connection with the operations of gold dredges assumed such proportions at one time that the State of California deemed it necessary to issue a special bulletin on this subject."

From Introduction: "Material for this report was gathered during the last quarter of 1928 and the first quarter of 1929, when the author visited the quick-silver-producing districts of California, Nevada, Texas, Oregon, Washington and Arizona to view the progress made in recent years and gather material for a comprehensive study of the present-day quicksilver industry of the United States."

From introduction: "In this paper are assembled and summarized many subjects relating to the copper industry in North America. Production of mines and districts, history of the industry in North America. Production of mines and districts, history of the industry, geology, of the principal deposits, and mining methods and costs are discussed."

From Introduction: "This report covers the essential features of the asbestos industry, including occurrence, production, mining, milling, utilization, international trade, and marketing."

From Introduction: "The present paper discusses regional resources, chiefly of gold, the existence of which has long been demonstrated by substantial production but which are so nearly marginal in value that their mining has been protracted and will probably continue indefinitely for many decades."

Report discussing the cultivation of plums and prunes in California, Oregon, Washington, and Idaho. Discussions includes geographic distribution, different varieties, propagation, fertilizers, harvesting, and common diseases and insect enemies.

Revised edition. "This bulletin applies both to the western portions of the United States in which ordinary farm crops are grown largely under irrigation and to western Oregon and Washington where irrigation is not essential for strawberry production but may be profitable. It describes methods practiced in the more important commercial strawberry-growing districts of the West; it aims to aid those persons familiar only with local and perhaps unsatisfactory methods, as well as inexperienced prospective growers. The fundamental principles of the irrigation of strawberries are substantially the same as those of irrigating other crops. Details must necessarily be governed largely by the character of the crop grown. Since strawberries in the humid areas frequently suffer from drought which causes heavy losses in the developing fruit, the information may prove suggestive to many growers in those areas who could install irrigation systems at small expense. This bulletin gives information on soils and their preparation, different training systems, propagation, planting, culture, the leading varieties, harvesting, shipping, and utilization." -- p. ii

"The information given in this bulletin should enable farmers in the Great Plains and Western States to select from the more common species of grasses some one or more suited to their needs [for soil and water conservation]. Common harvesting equipment and farm machinery can be adapted to the proper handling of native grasses. This brings the cost of such work within the means of most farmers." -- p. i. Among the grasses discussed are wheatgrass, buffalo grass, bluestem, grama, Bermuda grass, wild rye, hilaria, Sudan grass, bluegrass, panic grasses, dropseed, and needlegrass.

Revised edition. This bulletin discusses the cattle-fever tick and methods for controlling it. Possible methods include dipping, pasture rotation, and arsenical dips. The life history of the tick is also discussed.
