Eradication of Ferns from Pasture Lands in the Eastern United States

"There are nearly 7,500 recognized species of ferns in the world, of which number over 200 are known to be native to the United States. A few species have become weed pests in this country, and it is to a discussion of the control of these weedy ferns that this bulletin is devoted. The parts of the United States in which ferns are bad weeds are, principally, (1) the hill country of the Northeastern States and the higher portions of the Appalachian Mountain region as far south as Georgia, and (2) the Pacific coast country west of the Cascade Mountains.... This publication deals only with fern eradication in the Eastern States." -- p. 1-2

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."
