V.R. Wilmarth, Douglas H. Johnson
1953, Trace Elements Investigations 172
An area about 6 miles north of Sundance, in the Bear Lodge Mountains, in Crook County, Wyo., was examined during August 1950 for thorium, uranium, and rare-earth oxides and samples were collected. Uranium is known to occur in fluorite veins and iron-manganese veins and in the igneous rocks of Tertiary age...

Interpreting geologic maps for engineering purposes: Hollidaysburg quadrangle, Pennsylvania
Water Resources Division, U.S. Geological Survey
1953, Report
This set of maps has been prepared to show the kinds of information, useful to engineers, that can be derived from ordinary geologic maps. A few additional bits of information, drawn from other sources, are mentioned below. Some of the uses of such maps are well known; they are indispensable...
Abbreviations used in publications of the United States Geological Survey
Water Resources Division, U.S. Geological Survey
1953, Report
The use of abbreviations in publications of the Geological Survey is determined by several forces working in different directions. Pulling in the direction of greater condensation and the freer use of abbreviations and symbols is the desire to achieve greater economy in publications. Working in the opposite direction is the...

Ralph Hile
1953, The Fisherman (21) 7, 11-12, 14
This article has been prepared to present the results of recently completed statistical studies on the fishery in the State of Michigan waters of the lake. The tabulations of production of lake trout and the estimates of levels of fishing pressure and abundance in the various statistical districts have...
Fluctuations in the fisheries of State of Michigan waters of Green Bay
Ralph Hile, George F. Lunger, Howard J. Buettner
1953, Fishery Bulletin of the U.S. Fish and Wildlife Service (54) 1-34
Green Bay, traditionally a major center of production, has assumed in recent years a position of overwhelming dominance in the commercial fisheries of the State of Michigan waters of Lake Michigan. Within the 4-year period 1945-1948 the commercial take in State of Michigan waters of Green Bay increased from 3,317,000...
The movement of tagged lake trout in Lake Superior, 1950-52
Paul H. Eschmeyer, Russell Daly, Leo F. Erkkila
1953, Transactions of the American Fisheries Society (82) 68-77
A total of 733 native lake trout was tagged at two widely separated localities in Lake Superior; subsequent recaptures numbered 155 fish (21.1 percent) during the year following marking. In October 1950, 116 large lake trout (average total length, 27.3 inches) were tagged near Keweenaw Point, Michigan. Fifteen...
The effect of ether anesthesia on fin-clipping rate
Paul H. Eschmeyer
1953, Progressive Fish-Culturist (15) 80-82
As part of an experimental program to learn the effects of stocking lake trout (Salvelinus namaycush) in Lake Superior, 141, 392 fingerlings were marked at the Charlevoix (Michigan) Station of the U.S. Fish and Wildlife Service in October 1952. The adipose fin was removed from all fish, the right pelvic...
War on lampreys
James W. Moffett
1953, Philadelphia Enquirer, 23 August 1953 16-17
Vampire-like sea lampreys look somewhat like short sections of garden hose, swim like eels, and live solely on the blood of fishes. Their voracious appetites have been especially harmful to fish in the Great Lakes, and it is there that methods of underwater electrocution are being applied in their...
Lake fisheries need lamprey control and research
James W. Moffett
1953, The Fisherman (21) 10-11
Since 1921, when the first sea lamprey was recorded from Lake Erie, concern about this parasite in the Great Lakes above Niagara Falls, where previously it had never occurred, grew successively. At first, the concern was shared only in scientific circles, but as the parasite continued its persistent and...
Technique for the application of a streamer-type fish tag
Leonard S. Joeris
1953, Transactions of the American Fisheries Society (82) 42-47
Principal features of the technique are: attachment of the plastic tag by means of a nylon-thread loop prepared in advance of field work; use of a curved surgical needle with cutting edge and a split eye for application of the tag. The procedures for splitting the needle's eye and for...

Ultraviolet spectrophotometric determination of tantalum with pyrogallol
J. I. Dinnin
1953, Analytical Chemistry (25) 1803-1807
In a search for a more rapid method for the determination of tantalum in rocks and minerals, an intensive study was made of the tantalum-pyrogallol reaction recommended by Platanov and Krivoshlikov, and a better modified spectrophotometric procedure is given. The improved method consists in measuring the absorbancy of the tantalum-pyrogallol...
Method for determination of small amounts of rare earths and thorium in phosphate rocks
C. L. Waring, H. Mela Jr.
1953, Analytical Chemistry (25) 432-435
In laboratory investigations, interest developed in the possible rare-earth content of phosphate samples from Florida and the northwestern United States. Because of the difficulty of making chemical determinations of traces of individual rare earths, a combined chemical-spectrographic method was investigated. After removal of iron by the extraction of the chloride...
Analysis of mixed-layer clay mineral structures
W. F. Bradley
1953, Conference Paper, Analytical Chemistry
Among the enormously abundant natural occurrences of clay minerals, many examples are encountered in which no single specific crystallization scheme extends through a single ultimate grain. The characterization of such assemblages becomes an analysis of the distribution of matter within such grains, rather than the simple identification of mineral species....
Determination of traces of cobalt in soils: A field method
H. Almond
1953, Analytical Chemistry (25) 166-167
The growing use of geochemical prospecting methods in the search for ore deposits has led to the development of a field method for the determination of cobalt in soils. The determination is based on the fact that cobalt reacts with 2-nitroso-1-naphthol to yield a pink compound that is soluble in...
Systematic variation of rare earths in monazite
K. J. Murata, H. J. Rose Jr., M. K. Carron
1953, Geochimica et Cosmochimica Acta (4) 292-300
Ten monazites from widely scattered localities have been analyzed for La, Ce, Pr, Nd, Sm, Gd, Y and Th by means of a combined chemical and emission spectrographic method. The analytical results, calculated to atomic percent of total rare earths (thorium excluded), show a considerable variation in the proportions of...

Quercetin as colorimetric reagent for determination of zirconium
F. S. Grimaldi, C. E. White
1953, Analytical Chemistry (25) 1886-1890
Methods described in the literature for the determination of zirconium are generally designed for relatively large amounts of this element. A good procedure using colorimetric reagent for the determination of trace amounts is desirable. Quercetin has been found to yield a sensitive color reaction with zirconium suitable for the determination...
Semiquantitative spectrographic method for analysis of minerals, rocks, and ores
C. L. Waring, C. S. Annell
1953, Analytical Chemistry (25) 1174-1179
The quantity and complex nature of materials received for analysis in the spectrographic laboratories of the U. S. Geological Survey have emphasized the need for a spectrographic method to determine a maximum number of elements in a limited time with a reasonable degree of accuracy. The semiquantitative method described determines...
Geochemical studies of clay minerals III. The determination of free silica and free alumina in montmorillonites
Margaret D. Foster
1953, Geochimica et Cosmochimica Acta (3) 143-154
Determination of free silica by the method proposed made possible the derivation of logical formulas for several specimens of montmorillonites for which the formulas could not be derived from the analyses alone. Other montmorillonites, for which logical formulas could be derived from their analyses, were found to contain small amounts...
