Potash Salts from Texas-New Mexico Polyhalite Deposits: Commercial Possibilities, Proposed Technology, and Pertinent Salt-Solution Equilibria

From Introduction: "Figure 1 shows the location of sources that have been either exploited or seriously considered at one time or another, super-imposed upon a map indicating by small letters the order of consumption of K2O in the leading States; the amount used in these States, together with the percentage of the total consumption of potash used as fertilizer in the United States in 1939, is given in table 1. Figure 2 shows the domestic production and total consumption of potassium salts, in terms of tons of K2O, with the value per unit at the plants, for each year since 1913. Considered together, these two figures tell a significant story."

Coal-Mine Accidents in the United States and Foreign Countries (open access)

Coal-Mine Accidents in the United States and Foreign Countries

From Introduction: "The lack of comparable and accurate statistics of coal-mine accidents in the united States as a whole led the Bureau of Mines in 1911 to undertake the collection of such data. The mining departments of the leading foreign coal-producing countries have long taken cognizance of the importance of statistics. The bureau feels that in presenting the tables embodied in this report it is offering the and comparable statistics of coal-min accidents for the country as a whole that have ever been published."

From Introduction: "This volume contains the descriptions of the samples whose analyses are published in the preceding volume, Part I of this bulletin. The descriptions have been compiled from the notebooks of the persons who collected the samples, have been condensed from accounts given in published reports of the United States Geological Survey, or have furnished by the collection themselves. Inasmuch as the descriptions represent the work of many persons during a period of six years, and inasmuch as they were recorded under widely differing conditions, they necessarily vary in fullness detail."

An Example of Intensive Farming in the Cotton Belt

"This paper is descriptive of the improvement of an area of poor land by growing ordinary field crops under a system of farm management which aims at the incorporation of liberal amounts of organic matter in the soil as the chief factor in maintaining fertility and increased crop yields -- a practice which can not be too frequently brought to the attention of farmers. This system has produced greater returns to the farmer who practices it than any other system in use in his locality and will serve as an object lesson to many small farmers in all parts of the country." -- p. 2
