Comparison of the isotopic abundance of U235 and U238 and the radium activity ratios in Colorado Plateau uranium ores
F. E. Senftle, L. Stieff, F. Cuttitta, P.K. Kuroda
1957, Geochimica et Cosmochimica Acta (11) 189-193
The isotopic abundances of uranium and the radium activity ratios of eleven samples of uranium ore from the Colorado Plateau have been measured. No significant variation in the isotopic abundance of the uranium was noted; with'in the experimental error, the average U235/U238 ratio is 137.7. There is a significant variation in...
X-ray spectrographic determination of cesium and rubidium
J. M. Axelrod, I. Adler
1957, Analytical Chemistry (29) 1280-1281
An x-ray spectrographic method for the determination of rubidium and cesium was developed, using the internal-standard method and a four-channel flat-crystal spectrograph. The sensitivity is within 0.1% for cesia and 0.02% for rubidia; the precision is within 10% of the amount present. Results agree well with those obtained by flame...
Limnological surveys of the Great Lakes--early and recent
Stanford H. Smith
1957, Transactions of the American Fisheries Society (86) 409-418
Early explorations on the Great Lakes were concerned largely with things easily collected or observed—common organisms, water levels, surface temperatures … Even when more scientific studies were undertaken, they were at first scattered and small-scale. Effective surveys became possible only through inter-agency cooperation which permits a pooling of facilities, staff,...
The control of the upstream movement of fish with pulsated direct current
Alberton L. McLain
1957, Transactions of the American Fisheries Society (86) 269-284
Alternating-current electromechanical devices installed in the mouths of streams have proved effective in stopping the spawning migrations of the parasitic sea lamprey (Petromyzon marinus) which has seriously damaged Great Lakes fisheries. In a few streams, excessive mortality has occurred to other fish at the alternating-current barriers. A direct-current unit was...
Structure and growth of scales of yellow perch of Green Bay
Leonard S. Joeris
1957, Transactions of the American Fisheries Society (86) 169-194
The appearance of the scales of yellow perch differs with the location on the fish's body. Comparison of scales of Green Bay perch taken above and below the lateral line reveals the former to have more sharply defined circuli and to exhibit fewer false annuli and less of the shading...
Toxicity of 4,346 chemicals to larval lampreys and fishes
Vernon C. Applegate, John H. Howell, A.E. Hall, Manning A. Smith
1957, Special Scientific Report - Fisheries 207
The problem of controlling the sea lamprey in the upper Great Lakes has received considerable attention in recent years and requires no review here (Applegate and Moffett. 1955). Electromechanical weirs and traps and electrical barriers have been developed which can be successfully employed to block and/or destroy spawning runs of...

Ground water in the Crow Creek-Sand Lake area, Brown and Marshall Counties, South Dakota
F. C. Koopman
1957, Water Supply Paper 1425
The Crow Creek Sand Lake area is in the northeastern part of South Dakota and consists of flat to gently rolling land. It is roughly 25 miles square and is bounded on the west by the James River, on the north by the North Dakota State line, and on the...
On the postglacial history of the Devils Lake Region, North Dakota
Saul Aronow
1957, The Journal of Geology (65) 410-427
Devils and Stump lakes in eastern North Dakota have been diminishing in area more or less continuously since the land around them was settled in the 1880's. Desiccations similar to the current one have occurred at least once and possibly two or more times in the past and are indicated...
Core logs from two test holes near Kramer, San Bernardino County, California
Dayton Delbert Dickey
1957, Bulletin 1045-B
Between July 1954 and May 1955 two test holes were drilled near Kramer Calif., on the Mojave Desert. Four Corners test hole 1 was drilled in sec. 20 T. 10 N., R. 6 W., San Bernardino base line and meridian, to a depth of 1,561 feet in a basin filled...
Core logs from Owens, China, Searles, and Panamint basins, California
George I. Smith, Walden P. Pratt
1957, Bulletin 1045-A
Detailed logs of drill cores are presented in this report. The drill cores are of sediments from four basins that were occupied during the Pleistocene by a continuous chain of lakes. Owens Lake basin (one hole, 920 feet) contains fine-grained sediments and includes locally many diatoms and ostracodes. China Lake...

Ringworm in a population of snowshoe hares
Lowell W. Adams, S. B. Salvin, W. J. Hadlow
1956, Journal of Mammalogy (37) 94-99
The occurrence of ringworm, or dermatomycosis, in wild animals has been rarely reported. DeLamater (1939) described infections of Trichophyton mentagrophytes in common gray squirrels on and near the Johns Hopkins University campus at Baltimore. Errington (1942) and Charles (1946) reported on the occurrence of T. mentagrophytes in 35 of 364 litters (9.6%) of muskrats...
Lignasan for bacterial gill disease
Robert R. Rucker, B. J. Earp, Roger E. Burrows
1956, Progressive Fish-Culturist (18) 75-77
Bacterial gill disease plagues salmon and trout in many hatcheries: some infections are sporadic, but others are continual. An inexpensive, easily applied, stable, safe chemical would be highly advantageous for treatment. The use of Roccal as a 1-hour treatment for bacterial gill disease (Fish 1947) was developed at the...
Long-term trends of ground-water levels in the United States
V.C. Fishel
1956, Eos, Transactions, American Geophysical Union (37) 429-435
Ground-water levels at the end of 1954 were at or near record-low stages throughout most of the southern two-thirds of the United States. These low stages, like those of the early 1930's, have led to frequent expression of the opinion that the water table throughout the country is continuously falling...
Tissue damage in salmonids caused by Halisidota argentata Packard
E. M. Wood, W. T. Yasutake
1956, Journal of Parasitology (42) 544-546
During the histological examination of a collection of wild and hatchery salmonids, a peculiar foreign body was occasionally observed in various organs, particularly in the viscera. These objects, usually accompanied by a focal inflammation, were observed in 10 of 75 samples of wild trout and salmon collected in Oregon and...
Ground water in Wisconsin
William James Drescher
1956, Wisconsin Geological & Natural History Survey Information Circular 3
The purpose of this report is to describe in general the occurrence, source, movement, and use of ground water in Wisconsin in order that present problems of ground-water development may be understood and to point out the need for study and evaluation of the potential ground water available.

Preliminary chemical quality study in the Manhattan Beach area, California
Robert Brennan
1956, Bulletin 63-E
In 1904 Mendenhall (1905) made a survey of the ground water conditions in southern California. At the time of his survey the piezometric surface in the area was above sea level, but since that time water levels have declined. During the 1920's, years of rapid development, the water levels declined...
