Leaching and Precipitation Tests on Grants Ores
Leaching tests were run on two samples from the Grants area in New Mexico. Uranium extractions of 94 per cent were obtained by leaching Sample 6-1 with solutions containing 240 lbs. of Na2CO3 and 60 lbs. of NaHCO3 per ton and by leaching Sample 6-2 with 270 lbs. of Na2CO3 and 180 lbs. of NaHCO3 per ton. Cyclic tests were completed using caustic precipitation of the leach liquor.

Gas Discharges : Lecture Series
Most books on the subject of gas discharges describe the multiple banded structure which appears in the flow between two electrodes. This structure is actually due to the difficulty in getting electrons out of the cathode to support the discharge. These electrons are obtained by having a large enough potential drop near the cathode so that the positive ions may strike it hard enough to product secondary electrons. If one substitutes a hot cathode to produce a copious quantity of electrons, the banded structure will be radially changed. Hence the banding is not a pure property of the discharge, but is a complication brought on by the presence of electrodes.

Helium-Bearing Natural Gases of the United States: Analyses and Analytical Methods
Report published by the U.S. Bureau of Mines containing the results of a survey of the natural gas resources available in the United States. From the summary:"The Results of a Bureau of Mines survey of helium resources are given in this report and comprise gas analyses and accompanying data on more than 2,100 samples that have been collected in 30 States. The survey to determine the Nation's helium resources has been carried on in all natural-gas-producing areas of the United States since the inception of the Government's helium program in 1917. The primary purpose of the report is to present the results of this work in a tabulated form. A secondary purpose is to make public the historical background of the helium survey and to describe the methods of collecting gas samples and analyzing them. Detailed descriptions are given of the analytical equipment and procedures used in making the analyses" (p. 1).

Acid-Mine-Drainage Problems: Anthracite Region of Pennsylvania
Report from the U.S. Bureau of Mines discussing the anthracite region of Pennsylvania and the efforts to prevent coal-mine drainage into nearby streams. According to the introduction, "The purpose of this report is not to develop a practicable or feasible method or process of treating acid mine water but rather to present available factual and deduced data that may be useful in showing pH range over which the treatment is to take place and the sludge products most likely to be handled" (p. 2).
