Relations of bauxite and Kaolin in the Arkansas bauxite deposits
M.I. Goldman, Joshua Irving Tracey Jr.
1949, Economic Geology (41) 567-575
Investigation of the Arkansas bauxite deposits by the U. S. Geological Survey during the years 1942 to 1945 has brought out the fact that secondary kaolinization or silication of the bauxite is much more common than has been generally recognized. On the other hand no direct evidence was found of...
Natural water losses in mountain drainage areas of southern California
Harold C. Troxell, H.M. Stafford
1949, Eos, Transactions, American Geophysical Union (30) 752-758
For twenty‐five small mountain drainage areas of Southern California, natural water losses are shown to vary with basin altitude, and with estimated absorptive and retentive characteristics of the drainage areas. Among other relationships demonstrated is the increase of the annual natural water loss with increased annual precipitation to an optimum,...
Ground water in the East Shore area, Utah. Part I. Bountiful District, Davis County
H. E. Thomas, W.B. Nelson
1948, Technical Publication 5
The Bountiful district in Davis County, Utah, less than 10 miles from the heart of Salt Lake City, is rapidly becoming an integral part of the metropolitan area of Salt Lake City. It cannot achieve the development that its location merits unless the present water supplies are increased. The district...
A report upon the Grand Coulee Fish Maintenance Project 1939-1947
F. F. Fish, Mitchell G. Hanavan
1948, Special Scientific Report - Fisheries 55
The construction or Grand Coulee Dam, on the upper Columbia River, involved the loss of 1,140 lineal miles of spawning and rearing stream to the production of anadromous fishes. The fact that the annual value of these fish runs to the nation was estimated at $250,000 justified reasonable expenditures to...
New compounds for the control of bacterial gill disease
R.R. Rucker
1948, Progressive Fish-Culturist (10) 19-22
BACTERIAL GILL DISEASE, a common epizootic among hatchery fish, can be controlled by copper sulphate dips, as stated by Davis (1945), or by prolonged treatments with Roccal, as noted by Fish (1947). The use of copper sulphate is not without danger because of variation in toxicity according to the hardness...
The return on the blueback salmon to the Columbia River
Frederick S. Fisher
1948, Scientific Monthly (66) 283-292
THE year 1941 was a crucial one for the blueback salmon of the Columbia River. During that year, one brood came closer to extinction than was realized by more than a few individuals. The immediate causes were not overfishing, hydroelectric power development, or irrigation—although these factors continued to exert their...
Removal of excess nitrogen in a hatchery water supply
R.R. Rucker
1948, Progressive Fish-Culturist (10) 88-90
The water system at the U. S. Fish Cultural Station, Leavenworth, Washington, has been supplemented with two wells that were to be used to increase the temperature of the water during the winter and to cool the Water in the summer if necessary. The well water proved to be unsuitable...
Cranberry magnetite deposits Avery County, N.C., and Carter County, Tenn.
M.H. Kline, T.J. Ballard
1948, U.S. Bureau of Mines Report of Investigations 4274
The Cranberry magnetite deposits occur in pre-Cambrian granite-gneiss in a belt extending from 3 miles southeast of Cranberry, N.C., to about 6 miles southwest of Magnetic City, Tenn. The belt forms a curve, elongated to the north, approximately 26 miles in length....
