Revised edition. "This bulletin applies to that part of the United States in which ordinary farm crops are grown largely under irrigation. It describes methods practiced in the more important commercial strawberry-growing districts in the irrigated regions of the West; it aims to aid those 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 which apply in the growing of other crops. Details of operation must necessarily be governed largely by the character of the crop grown. Since strawberries in the humid regions frequently suffer from drought, which causes heavy losses in the developing fruit, the information may prove suggestive to many growers in those localities who could install an irrigation system at small expense. Detailed information is also given as to soils and their preparation, different training systems, propagation, planting, culture, the leading varieties, harvesting, and shipping. Methods of using surplus strawberries for preserves and jams, for canning, and for flavoring for various purposes are given." -- p. 3

From introduction: The district discussed in this report embraces the entire northern peninsula of Michigan and the parts of northern Wisconsin and northeastern Minnesota that were covered by a re-advance of the Superior lobe of the Labrador ice sheet late in the Wisconsin stage of glaciation.

Report discussing the weed commonly known as dodder or love vine and methods for controlling it. If procedures are properly followed, eradication of the weed in the United States is possible. Topics include varieties of dodder and plants that susceptible to attack by it, its life cycle, and ways it is unintentionally introduced to farms.

Report discussing the beet leaf-beetle, which is common in the Rocky Mountain region. Discussion include physical appearance, geographic distribution, life cycle, affected plants, and methods of control.

Report discussing the different varieties of durum wheat, their various uses, and areas to which they are best adapted. Among the varieties discussed are Kubanka, Arnautka, Mindum, Buford, Acme, Monad, Marouani, Pentad, and Peliss.

Report describing the types of wheat known as emmer and spelt, which are not widely grown in the United States and differ from other types of wheat in that most of the kernel is not removed from the chaff during threshing. The history, distribution, adaptation, varieties, culture, harvesting and threshing, and uses of both emmer and spelt are discussed.

This bulletin discusses take-all, a fungal disease of wheat, and methods for controlling it. It also describes the distribution, symptoms, and causes of take-all.

"The sugar-beet nematode is one of the most serious of the beet pests. It appears to have been imported with some shipments of beet seed many years ago. It has been found widely scattered in four of the western sugar-beet States and probably exists in other States where beets have been grown for several years. The sugar-beet nematode is the cause of a great deal of loss to the beet grower through reduction of his tonnage, and of a corresponding amount of loss to the sugar producer through reduction of the output of sugar. This bulletin treats of the nature and distribution of the sugar-beet nematode, indicates the most probable means by which this pest is spread, and suggests preventive measures and practical means of control." -- p. 2

This bulletin discusses the classes and varieties of hard red winter wheats and the areas in which they are successfully grown. Among the varieties discussed are Turkey, Kharkof, Kanred, Blackhull, Minturki, and Baeska.

From Introduction: "The Bureau of Mines since its establishment has always taken an active interest in the utilization of lignite and in the development of the lignite deposits of the United States. Extensive lignite fields occur in the west central States, notably in North Dakota, Montana, Wyoming, Colorado, and Texas; there are smaller areas in several other Sates, some of which are widely separated."

Report discussing the the development of milling practice in Boulder County, the ore-dressing methods in use, and the local manufacture of ferrotungsten and tungstic oxide. Figures giving the production of tungsten concentrates in the Boulder district, in the United States, and in the world; data on the buying of tungsten ores; costs of production; and the normal tungsten requirements in this country are presented.

Report issued by the Bureau of Mines discussing the demands on the oil industry due to an increase in automobiles in the United States. Improvements in drilling methods and refinery practices are presented. This report includes a table.

Report issued by the U.S. Bureau of Mines over state mine inspection reports from 19 U.S. states. The information in the reports includes details of accidents, locations that specific accidents occurred, and proposed remedies for prevention of future accidents. This report includes tables.

Technical paper issued by the Bureau of Mines over the Bowie-Gavin process. As stated in the introduction, "this paper describes a process and an apparatus designed to recover oil from such deposits" (p. 1). The results of experiments conducted using this process are discussed. This paper includes tables, illustrations, and photographs.
