Handling Barnyard Manure in Eastern Pennsylvania (open access)

Handling Barnyard Manure in Eastern Pennsylvania

"Barnyard manure is handled with special care and excellent results by farmers in certain parts of Eastern Pennsylvania. For over a century it has been the custom in this region to store stable manure in a walled manure yard, partly or wholly covered, in which the stabled animals are allowed to exercise during the day. Manure thrown into such a yard and thoroughly tramped by stock loses much less through heating and leaching than does manure piled in the open. This bulletin describes the manure-yard method of handling manure and outlines the farm practices of ten successful farmers who follow this method." -- p. 2

Essential Factors in the Formation of Producer Gas

From Introduction Scope and Purpose of Inquiry: "The Bureau of Mines, to which the testing and analyzing of fuels as carried on by the United States Geographical Survey has been transferred, is continuing producer-gas investigations at the testing station at Pittsburgh, Pa. Results of the gas-producer tests made at the coal-testing plant erected at St.Louis, Mo., and of a study of some of the problems that came up in the tests have been published by Geological Survey. Results of the tests made at Norfolk, Va., and Pittsburgh, Pa. and of further studies of particular problems, will be published by the Bureau of Mines."

Eradication of Ferns from Pasture Lands in the Eastern United States (open access)

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
