Wildlife Conservation Through Erosion Control in the Piedmont (open access)

Wildlife Conservation Through Erosion Control in the Piedmont

"Erosion has left scars on a majority of farms in the Southeast. Too poor to produce crops, the eroding spots are usually abandoned. Unless they are treated to stop further washing of the soil they grow steadily larger and continually rob the farmer of more of his land. Fortunately, soil conservation and wildlife management can be effectively combined, and otherwise worthless areas made to produce a crop of game, fur bearers, and other desirable types of wildlife. The general principles of wildlife management on the farm are described in Farmers' Bulletins 1719 and 1759. The purpose of this bulletin is to show how gullies, terrace outlets, waterways, eroding field borders, pastures, and woodlands in the Piedmont region may be protected against erosion through the use of vegetation that will also provide food and cover for wildlife." -- p. ii

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

A Simple Way to Increase Crop Yields: Methods Followed by Farmers of the Coastal Plain Section of the Central Atlantic States in Building Up Soil Fertility

"The soils of the coastal plain section of the Central Atlantic States, as a rule, are light in character, have been farmed for generations, and need first of all a liberal supply of organic matter. This need should be met by growing such legumes as crimson clover, cowpeas, soy beans, red clover, and hairy vetch. Rye, buckwheat, and the grasses are also valuable in this connection. Commercial fertilizer and lime should be used freely when necessary to stimulate the growth of these soil-improving crops. By arranging the cropping system to include one or more legumes that supply the land with nitrogen and humus, crop yields have been greatly increased on many farms scattered throughout this region. The systems followed on a few of the more successful of these farms are described in detail in the following pages." -- p. 2

The Wheat Jointworm and Its Control (open access)

The Wheat Jointworm and Its Control

Revised edition. "The wheat jointworm is a very small grub which lives in stems of wheat, sucking the juices of the plant and causing a swelling in the stem. The egg from which it hatches is laid in the stem by an insect resembling a small black ant with wings. This insect attacks no other kind of plant. The injury which it does to wheat is very distinct from that caused by the Hessian fly, yet the depredations of these two insects are often confused by farmers. This paper is intended, therefore, to give a brief outline of the life history and the nature of the injury to the plant by the jointworm so that any farmer may readily recognize its work and be able to apply the measures of control herein recommended." -- p. 3-4

How to Attract Birds in the Middle Atlantic States

Where proper measures of this kind have been taken an increase of several fold in the bird population has resulted, with decreased losses from depredations of injurious insects. This bulletin is one of a series intended to describe the best methods of attracting birds in various parts of the United States, especially by providing a food supply and other accessories about the homestead." -- p. 2.

Methods are also given which may be used in case the clovers are valuable as sources of nectar." -- p. 2

Injury Experience in the Coking Industry, 1951

From Introduction and Summary: "Reports from operating companies showed that 25,715 men worked at coke ovens in 1951, about 6 percent more than were employed in 1950 and, except in 1943, the largest work force since 1930, when 28,139 men were employed. The work time for all employees was 70,190,493 man-hours. The returns indicated an average of 344 work days per man as compared with 341 days in the previous year. Accidents at the ovens resulted in the death of 10 and injury to 768 workers, both of these figures representing fewer injuries than in 1950."
