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...

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...
A more comprehensive description of Bacterium salmonicida
P. J. Griffin, S. F. Snieszko, S. B. Friddle
1953, Transactions of the American Fisheries Society (82) 129-138
The purpose of this study was to establish a set of descriptive data which could be used as a reference or a standard in the identification of Bacterium salmonicida, the cause of furunculosis in fish. Since a complete description of B. salmonicida was not available, bacteriologists were not in...

Trout fishing in Michigan waters of Lake Superior, 1952
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...
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...
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...
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...
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...
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...
Lake Bonneville: Geology of northern Utah Valley, Utah
C. B. Hunt, H.D. Varnes, H. E. Thomas
1953, Professional Paper 257-A
Lake Bonneville was a vast Pleistocene lake that covered 20,000 square miles in northwestern Utah and had a maximum depth of about 1,000 feet. It was a body of water comparable in size to modern Lake Michigan.Surveys of the unconsolidated deposits in the Lake Bonneville basin utilize the same methods...

Ground-water conditions in artesian aquifers in Brown County, Wisconsin
William James Drescher
1953, Water Supply Paper 1190
The principal water-bearing rocks underlying Brown County, Wis., are thick sandstone units of Cambrian and Ordovician age. Other aquifers include limestone and dolomite of Ordovician age, dolomite of Silurian age, and sands and gravel of Pleistocene and Recent age. Underlying the water-bearing formations are crystalline rocks of pre-Cambrian age which...

The use of soils and paleosols for interpreting geomorphic and climatic history of arid regions
John Miller, Luna Bergere Leopold
1953, Research Council of Israel Special Publication 2
The study of modern surface soils, and ancient weathering zones, which occur either buried or as surface relicts, has contributed materially to understanding the complex events of the glacial and post-glacial period both in glaciated areas and in regions not influenced by glaciation. Most work of this kind in the...
Relation of suspended-sediment concentration to channel scour and fill
Luna Bergere Leopold, Thomas Maddock Jr.
1953, Conference Paper, Proceedings of the fifth Hydraulics Conference, June 9-11, 1952, arranged by the Iowa Institute of Hydraulic Research
It is known that during the passage of a flood the channel of an alluvial stream scours and fills with considerable rapidity. Though such changes may be random, it seems more likely that there is a definite pattern of channel change directly related both to discharge and to the sediment...

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 (12.9 percent)...
