1. An extensive field check was made of snipe habitat in those parts of western Canada (excluding most of British Columbia) which are accessible by road. 2. Nesting snipe were found to be very scarce in the whole Short-grass Prairie region, widely distributed and locally common in the Parklands,...

1955, Water Supply Paper 1330
The early industries in America generally were established when and where demands for the products of industry arose. Most of the early industries were so located that their increasing requirements for transportation, raw materials, market, labor, and water supply could be satisfied economically. Many of these original plant locations have...

Water-power resources in upper Carson River basin, California - Nevada
Harold L. Pumphrey
1955, Water Supply Paper 1329-A
West Fork Carson River offers the best opportunity for power development in the Carson River basin. The Hope Valley reservoir site could be developed to provide adequate storage regulation and concentration of fall would permit utilization of 1,400 feet of head in 51h miles below the clam site, or 1,900...

The thoron-tartaric acid systems for the spectrophotometric determination of thorium
F. S. Grimaldi, Mary H. Fletcher
1955, Trace Elements Investigations 571
Thoron is popularly used for the spectrophotometric determination of thorium. An undesirable feature of its use is the high sensitivity of the reagent toward zirconium. This study describes the use of tartaric acid as a masking reagent for zirconium. Three tartaric acid-thoron systems, developed for the determination of thorium, differ...
Some physical properties of naturally irradiated fluorite
Robert Berman
1955, Trace Elements Investigations 569
Five samples of purple fluorite found in association with radioactive, materials, and a synthetic colorless control sample were studied and compared. Before and after heating, observations were made on specific gravity, index of refraction, unit-cell size, breadth of X-ray diffraction lines, and fluorescence. The purple samples became colorless on heating...
