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."

Crop Systems for Arkansas (open access)

Crop Systems for Arkansas

"Crop systems for Arkansas that make for increased food production and increased efficiency in man labor and horse labor are described in the following pages. By the introduction of cowpeas, soybeans, and other legumes, and by second cropping, provision is made for a considerable increase in the number of crop acres that can be farmed by the average family.... In each of the cropping systems suggested the crop acreages are calculated for two men and a team, and for light, medium, and heavy soils. These systems in general apply to all of Arkansas, except the northwestern part, and some of them may be used to advantage in northern Louisiana, northeastern Texas, southeastern Oklahoma, western Tennessee, and the northern half of Mississippi." -- p. 2
