Fluorspar Deposits in Western Kentucky: Part 1 (open access)

Fluorspar Deposits in Western Kentucky: Part 1

From introduction: The need for fluorspar in the manufacture of open-hearth steel, hydrofluoric acid, aluminum, certain insecticides, refrigerants and airconditioning compounds, welding rods, 100-octane gasoline, and many other products necessary to the prosecution of World War II resulted in unprecedented demands for this commodity. To help increase production to meet these demands, the War Production Board in 1942 asked the United States Geological Survey to plan a comprehensive study of the fluorspar deposits in the United States. This study has been carried on in many parts of the country in cooperation with geologists and engineers of State and Federal agencies and with local producers.

Fluorspar Deposits in Western Kentucky: Part 2 (open access)

Fluorspar Deposits in Western Kentucky: Part 2

From abstract: The central part of the Commodore fault system is in the western Kentucky fluorspar district, in Crittenden County, about 6 miles northwest of Marion. It has yielded from 30,000 to 40,000 tons of crude fluorspar and nearly 20,000 tons of zinc ore. Limestones, sandstones, and shales of the Meramec, Chester, and Pottsville groups of Carboniferous age crop out as relatively flat-lying beds, except near faults. The rocks are transected by high-angle normal faults. The main faulted zone is the Commodore fault system, which displaces the beds from 1,500 to 2,000 feet. The principal vein minerals are fluorite, calcite, smithsonite, sphalerite, and galena. Fluorite and smithsonite are the chief ore minerals, occurring as lenses along the faults. The mines have been worked since 1892, but most of the workings are caved or filled with water.

Fluorspar Deposits in Western Kentucky: Part 3 (open access)

Fluorspar Deposits in Western Kentucky: Part 3

Abstract: The Moore Hill fault system in the central part of the Kentucky-Illinois fluorspar field is about 26 miles long. Fluorspar has been produced from a part nearly 5 miles long, and since mining began in 1899 this system has yielded more than 300,000 tons of fluorspar. Lead and zinc sulfides commonly are found in the ore, but only rarely do they occur in sufficient quantity to be worth recovering. The productive part of the fault system was mapped and the properties and principal mines described. The high-angle normal faults of the system cut limestones, sandstones, and shales of Mississippian age. Stratigraphic displacements range from less than a foot to as much as 550 feet. The fluorspar bodies are sporadically distributed in veins of calcite and fluorite along the faults.

Coal Reserves of the Boltsfork Quadrangle, Kentucky: A Coal Recoverability Study

Abstract: "This report presents a U.S. Bureau of Mines study that incorporates coal mining factors, cola recovery factors, and economic factors into the definition of an economically recoverable coal resource. The relationship between these factors to the Energy Information Administration's estimate of U.S. coal resources--the "Demonstrated Reserve Base"--is discussed. The Boltsfork 7 1/2-minute quadrangle in eastern Kentucky was selected as the stud area. Results indicate that of the original 280.2 M tons of resource in the quadrangle, only 99.8 M tons (35.6%) is recoverable at a mining cost of $25 per ton or less" (p. 1).

Chestnut Blight (open access)

Chestnut Blight

"Chestnut blight, caused by a fungus brought into this country from Asia before 1904, is responsible for the death of millions of acres of chestnut growth in New England and the Middle Atlantic States. The disease spread rapidly to nearly all parts of the range of the native chestnut, and the remaining stands of the southern Appalachians face certain destruction. The present known distribution, its symptoms, and the fungus that causes the disease are described. The blight fungus itself does not have any effect upon the strength of chestnut timber, and blight-killed trees can be utilized for poles, posts, cordwood, lumber, and extract wood. Search is being made for native and foreign chestnuts resistant to the disease in the hope of finding a tree suitable for replacing the rapidly disappearing stands. Seedlings of Asiatic chestnuts, which have considerable natural resistance even though not immune, are being tested in the United States." -- p. ii

Farm Practice with Lespedeza (open access)

Farm Practice with Lespedeza

"The use of lespedeza as a farm crop has rapidly increased during the past few years. The increase in the use of lespedeza is due partly to the excellent results that have been obtained by the farmers who have been growing the Common variety, for hay and for pasture and soil improvement, but more particularly to the introduction of some new varieties that produce better yields, are adapted to a wider range of climatic conditions, and are generally better suited to the needs of the average farm than is the Common variety. This bulletin is based on information collected from farmers located in the States of Virginia, North Carolina, Tennessee, and Kentucky who are growing lespedeza regularly as a farm crop. The information includes methods of seeding, varieties used, the place in the cropping system usually occupied by lespedeza, and practices that have developed in connection with the production and use of the crop in these States." -- p. 1

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

Ways of Making Southern Mountain Farms More Productive (open access)

Ways of Making Southern Mountain Farms More Productive

"The southern mountain farm often produces no more than a scant living for the family. Corn is the chief crop grown. Often part of the farm lies idle, being 'rested' while corn is grown on another part year after year until the land is worn out. By growing three or more crops in rotation, including clover, the farmer will be able to produce larger crops, make more money, and keep all crop land under cultivation all the time. Cattle, hogs, and sheep will not only add to the cash income, but will help to increase the fertility of the soil, and render larger crops possible. This bulletin describes crop rotations for small mountain farms in the southern Alleghenies, and gives complete directions for starting a crop rotation that will make poor mountain land more productive." -- p. 2

The Southern Corn Rootworm and Farm Practices to Control It (open access)

The Southern Corn Rootworm and Farm Practices to Control It

"Of all corn pests in the South one of the most serious is the larva, or young, of the 12-spotted cucumber beetle -- the so-called southern corn rootworm. True to its name, it feeds on the roots, but in young corn it also drills a small hole in the stem just above the first circle of roots, boring out the crown and killing the bud.... Progressive farming methods, as described in this bulletin, will reduce the ravages of this insect. Burn over waste places to destroy dead grass, weeds, and rubbish in which the beetles winter. If possible, avoid planting corn in fields which contained corn the year before. Enrich the soil by planting legumes so that the corn will have a better chance of recovering from rootworm injury. Protect the bobwhite. This bird destroys many beetles of the rootworm. By careful observations, extending over a period of years, find out the dates between which the rooworm does the most damage; then time your planting so that it will fall either before or after these dates, taking into consideration, of course, other important factors in crop production." -- p. 2
