Report issued by the U.S. Bureau of Mines on the exploration of zinc ore deposits surrounding the Powell River area in Tennessee. Drilling methods and ore concentrates are presented. This report includes tables, and maps.

Revised edition. "The wheat jointworm is a very small grub which lives in stems of wheat, feeding on the juices of the plant and causing a slight swelling or distortion of the stem above the joint. The egg from which it hatches is laid in the stem by an insect resembling a small black ant with wings. This insect attacks wheat only. The injury which it causes to wheat is very distinct from that caused by the Hessian fly, yet the effects caused by these two insects are often confused by farmers." -- p. 1-2. This bulletin gives a brief outline of the life cycle 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.

This bulletin discusses the cultivation of Persian clover, a forage crop for both feed and green manure in the southern United States. Fertilizer requirements and seed production are among the topics discussed.

Revised edition. "Muscadine grapes, which are native to the southeastern part of the United States, thrive in most soils of that region. They can be grown successfully in the Southeastern States, where American bunch grapes do not thrive. furthermore, they are suitable for home gardens as well as for commercial use. In fact they are perhaps the most satisfactory of all fruits for the home garden in this region. They cannot be grown, hoever, where temperatures as low as 0 °F occur habitually and may be injured at somewhat higher temperatures. Muscadine grapes are relatively uninjured by diseases and insects and produce well with a minimum of care, but they resopnd favorably to the good cultural practices recommended in this bulletin. The varieties described or listed produce fruit suitable for making unfermented juice, wine, jelly, and other culinary products and for eating fresh over a long season." -- p. ii

Revised edition. This bulletin discusses the cattle-fever tick and methods for controlling it. Possible methods include dipping, pasture rotation, and arsenical dips. The life history of the tick is also discussed and instructions for constructing a concrete vat are given.

Report issued by the Bureau of Mines over the operations of the Nonmetals Division during 1942. The work done by the division is discussed. This report includes tables, illustrations, and photographs.

From abstract: Perry and Lewis Counties, east of the Tennessee River, in west-middle Tennessee, are underlain by nearly flat-lying rocks of Paleozoic age, with Mississippian cherty limestones forming the greater part of the surface of the western Highland Rim Plateau ridges. Near the summits of the ridges there is a fairly definite horizon in the chert that contains manganese and iron oxides in varying degrees of concentration. Weathering of the mineralized chert has produced widespread float on the hill slopes and in the beds of small spring branches, and the presence of this float, some of it rich enough for metallurgical manganese ore, has encouraged a search for promising deposits in place. In the present study 52 localities where the mineralized beds crop out or have been prospected were examined.

The following report describes the findings from an investigation of a uranium-bearing strata undertaken in Hickman and adjacent counties in west-central Tennessee during the summer and fall of 1944. The strata contained radioactive elements within the Chattanooga shale and the Maury glauconitic member of the Ridgetop shale.

Report discussing an Chattanooga shale adit for laboratory test samples of rock and gaining information regarding mining conditions.

Report discussing the U.S. Geological Survey's investigation of the radioactivity measurements of asphalltites, coals and shales found in Tennessee, Kentucky, West Virginia, and Pennsylvania.

Report discussing an investigation of radioactive Chattanooga black shale found in east central Tennessee.

The following report is based on the observations made during a visit to the Oak Ride National Laboratories of their Redox Pilot Plant equipment.

The following report covers the results of a general program that was conducted at the Oak Ridge National Laboratory to investigate the effects on plastic materials of exposure to radiation in the pile. In the investigation, several plastics were irradiated, and on removal from the pile, their rates of decay were determined by measurement of gamma activity in an ionization chamber.
