Determination of thorium and of rare earth elements in cerium earth minerals and ores
M. K. Carron, D. L. Skinner, R.E. Stevens
1955, Analytical Chemistry (27) 1058-1061
The conventional oxalate method for precipitating thorium and the rare earth elements in acid solution exhibits definite solubilities of these elements. The present work was undertaken to establish conditions overcoming these solubilities and to find optimum conditions for precipitating thorium and the rare earth elements as hydroxides and sebacates. The...
Theoretical effect of diffusion on isotopic abundance ratios in rocks and associated fluids
F. E. Senftle, J. T. Bracken
1955, Geochimica et Cosmochimica Acta (7) 61-76
Diffusion is considered as a possible process of isotope fractionation taking place throughout geologic time. Both diffusion in solids and diffusion in liquids are taken as possible mechanisms, the latter being more important. Arguments are presented to show that if significant fractionation takes place within a crystal by outward diffusion...
Determination of small and large amounts of fluorine in rocks
F. S. Grimaldi, B. Ingram, F. Cuttitta
1955, Analytical Chemistry (27) 918-921
Gelatinous silica and aluminum ions retard the distillation of fluorine in the Willard and Winter distillation method. A generally applicable, simple method for the determination of fluorine in rocks containing aluminum or silicon or both as major constituents was desired. In the procedure developed, the sample is fused with a...

Some contributions of the Cooperative Wildlife Research Units to forest wildlife management
Daniel L. Leedy
1955, Journal of Forestry (53) 630-635
Although the Cooperative Wildlife Research Unit Program is nationwide in scope and has been in existence since 1935, it is probable that many readers of the Journal of Forestry are unaquainted with the program's objectives and accomplishments. This paper was written at the suggestion of a S.A.F. member to provide...
Geology and ground-water resources of Webster County, Iowa
William E. Hale
1955, Water Supply Bulletin 4
Webster County, comprising an area of 718 square miles just northwest of the center of Iowa, had a population of 44,241 in 1950, with 25,115 in Fort Dodge, the principal city. Some 94.4 percent of the county is in farm land; corn is the principal crop and is used in...
Germanium and uranium in coalified wood from upper Devonian black shale
Irving A. Breger, J. M. Schopf
1955, Geochimica et Cosmochimica Acta (7) 287-293
Microscopic study of black, vitreous, carbonaceous material occurring in the Chattanooga shale in Tennessee and in the Cleveland member of the Ohio shale in Ohio has revealed coalified woody plant tissue. Some samples have shown sufficient detail to be identified with the genus Cauixylon....
Flood control problems

Throughout the world, alluvial soils are among the most fertile and easiest cultivated. Alluvial valleys are routes for transportation either by water or by road and railroad. Rivers are sources of water, a necessity of life. But these river valleys and alluvial deposits, which have so many desirable characteristics and...
Sixth progress report on the cooperative investigation of springs and streamflow in the Tecolote Tunnel area of Santa Barbara County, California
Walter Hofmann
1955, Open-File Report 55-66
This report is the sixth in a continuing series of progress reports giving the results of discharge measurements obtained at more than 120 selected sites in the "Tecolote Tunnel Area" of the Santa Ynez Mountains. The area derives its name from the tunnel now being completed by the Bureau of...

An electrical device for computing theoretical draw-downs of ground-water levels
Irwin Remson, M.H. Halstead
1955, Open-File Report 55-149
The construction, calibration and use of an electrical "slide rule" for computing theoretical drawdowns of ground-water levels are described. The instrument facilitates the computation of drawdowns under given conditions of discharge or recharge by means of the Theis nonequilibrium equation. It is simple to construct and use and can be...

Sediment investigations of the Platte River near Overton, Nebraska
C.D. Albert, H.P. Guy
1955, Report
This report contains results of sediment-transport investigations on the Platte River near Overton,. Nebr. from January 1950 to September 1953. The basic data of suspended-sediment studies, results of bed-material analyses, and determinations of water-surface slopes from staff readings are given. The data indicate that a reliable determination of suspended sediment, hence...
Ground water resources of southeastern Oakland County, Michigan

Infectious diseases of Pacific salmon
Robert R. Rucker, B. J. Earp, E. J. Ordal
1954, Transactions of the American Fisheries Society (83) 297-312
Investigations on infectious diseases of Pacific salmon due to micro-organisms other than viruses are reviewed. The etiological agents include trematodes, fungi, protozoa and bacteria. Bacteria have been found to be the most important agents of disease in the several species of Pacific salmon. Kidney disease, due to a small, unnamed...
Virus diseases of fish
Stanley W. Watson
1954, Transactions of the American Fisheries Society (83) 331-341
Viruses are probably the cause of a wide spectrum of fish diseases. Although relatively few virus diseases of fish are known today, some of the diseases of unknown etiology, as well as some diseases presently accepted as due to bacteria, protozoa, fungi or nutritional deficiencies, possibly will be recognized eventually...
A virus disease of sockeye salmon: Interim report
S.W. Watson, R.W. Guenther, R.R. Rucker
1954, Special Scientific Report - Fisheries 138
Since 1951 a disease, usually occurring in late spring or early summer, has caused severe losses in 3- to 12-month-old fingerling sockeye salmon in hatcheries in the State of Washington. The disease is characterized by an explosive outbreak, mortality usually 80 percent or greater, and a residual spinal deformity in...
