From Introduction and Summary: "This bulletin describes the third series of coal-dust explosion tests by the Bureau of Mines in its experimental mine and covers a period from 1919 to the end of 1924, inclusive. A few related tests made in 1925 are also included."

Report compiled by the U.S. Bureau of Mines including statistics on fatalities in coal mines located in the United States as well as data regarding the various operations (e.g., number of miners employed and average production). The information is organized into tables for comparison and the text draws some overall conclusions in the summary.

Technical paper issued by the Bureau of Mines over mining of red iron ores in Birmingham, Alabama. As stated in the introduction, "the present paper deals more specifically with the development and handling of ore as affected by folds and faults in the ore bed, and considers changes that may be desirable or necessary in future mining practices" (p. 2). This paper includes illustrations, and photographs.

"This bulletin deals with the dry-farming methods practiced on grain farms in the Pacific Northwest, where the rainfall is less than 15 to 18 inches annually, but it also contains advice helpful to all farmers of that region who practice summer fallowing. Its purpose is to show the possibility of increasing crop yields in the dry-farming areas by using improved methods and to discuss the practices which have been found most advantageous. ...The highest yields have been secured by plowing in the early spring and giving enough cultivation after plowing to keep the weeds well under control. The purposes of summer fallowing and details of the methods by which it is accomplished are given, and the application of these methods to the cultivation of "blow" soils and "nonblow" soils. Methods are suggested for preventing and stopping the blowing of soils. Attention is given to the saving of man labor by the use of large power units, methods of seeding winter and spring wheat are outlined, and suggestions are made for maintaining the organic matter in the soil." -- p. ii

Report issued by the Bureau of Mines over studies conducted on the ferric sulphate-sulphuric acid process. As stated in the introduction, "the work reported here comprises merely a study of the chemistry of the process and the mechanical conditions that would have to be observed in practice" (p. 1). This report includes tables, and illustrations.

From Preface: "The importance of fluorspar in the industrial development of this country, particularly in the open-hearth steel industry, has only begun to be realized fully, The World War showed that fluospar was an essential mineral and was not as abundant as has been supposed. Mr. Ladoo visited nearly all the important fluorspar mines and mills in the United States and obtained as much information as possible regarding foreign deposits, production and methods."

"This bulletin deals with those cultivated forage crops that seem of greatest promise for the dry-farming districts of northern Nebraska and the Dakotas west of the ninety-eighth meridian. Frequent crop failures in the more arid portions of these States result from a low annual precipitation, the irregularity of its amount and distribution during the growing season, and high evaporation. Under conditions of extreme drought, cultivated crops can seldom be economically substituted for native vegetation, and the utilization of such lands for grazing and the cutting of wild hay is most generally advisable. Greater forage production on the better lands may be effected by growing certain cultivated legumes, grasses, and roots." -- p. ii.

Revised edition. This bulletin discusses methods for handling, loading, and transporting southern new potatoes in the United States. It explains the importance of grading potatoes, removing bruised and diseased potatoes from the crop before transport, and loading cars properly. Potatoes may be loaded into cars in barrels, sacks, and crates, but hampers should not be used.
