Neascus infection of black-head, blunt-nosed, and other forage minnows
G. E. Klak
1940, Transactions of the American Fisheries Society (69) 273-278
Black‐head, blunt‐nosed, and other minnows were found infested with encysted flatworms in ponds at Leetown, West Virginia. The mortality in a 2.2‐acre pond stocked with 100,000 black‐head minnows was about 250 per day during four weeks of observation. Heavy infestations caused sterility in the minnows. The cyst and parasite are...
Scyphidia micropteri, a new protozoan parasite of largemouth and smallmouth black bass
E. W. Surber
1940, Transactions of the American Fisheries Society (69) 169-175
A small urn‐shaped peritrichous protozoan, apparently an undescribed species, was found on the gills and bodies of largemouth and smallmouth black bass in ponds at Leetown, West Virginia. A heavy mortality among a lot of fingerling largemouth bass probably resulted from suffocation due to the organisms on the gills. Specimens...
Ridge-making thin sandstone in Frederick County, Virginia: Chapter C
R.S. Edmundson
1939, Book chapter, Contributions to Virginia Geology--II
It is generally recognized that massive thick-bedded sandstones and relatively weak shales and soluble limestones form characteristic surface features. The uncommon effect of a thin argillaceous sandstone in producing ridges in an area in northern Virginia, in which the writer has recently done detailed field work, is briefly described in...
A history of the Water Resources Branch of the United States Geological Survey: volume 4, years of World War II, July 1, 1939 to June 30, 1947

1939, Report
This period extends from July 1, 1939, to June 30, 1947, and is called the years of World War II, although it was not until December 1941 that the United States entered the war which began in Europe in September 1939. By the beginning of the period, it was evident...
Simplified methods for the prolonged treatment of fish diseases
F. F. Fish
1939, Transactions of the American Fisheries Society (68) 178-187
The prevention or control of epidemics of fish diseases by applying a disinfecting solution in a uniform concentration directly to the water supply of a fish pond or trough for a definite period of time has been exceedingly slow in development. In so far as can be determined, the original...
Notes on the effect of low temperature upon eyed eggs
F. F. Fish, R.E. Burrows
1939, Progressive Fish-Culturist (6) 28-31
The question has sometimes been raised whether or not any permanent injury may be inflicted upon fish eggs through their subjection to the relatively low temperatures prevailing in egg cases during shipment. This question may be argued in either direction purely upon the basis of indirect evidence which can be summoned...
Notes on Myxobolus inoratus, n sp, a Myxosporidian, parasitic in the black bass (Huro floridana, Le Sueur)
F. F. Fish
1939, Transactions of the American Fisheries Society (68) 173-177
A largemouth black bass fingerling preserved in formalin was sent to the U.S. Bureau of Fisheries Pathology Laboratory at Seattle, Washington, during the autumn of 1937, by a hatchery employee at Miles City, Montana. The fish exhibited several wart-like protuberances on the caudal peduncle, which aroused the curiosity of Mr....
Disease prevention in the trout hatchery
F. F. Fish
1939, Progressive Fish-Culturist (6) 1-7
With the comparatively recent evolution of fish hatching into true fish culture the problems offered by fish disease have likewise evolved from more or less of a petty annoyance into a first class headache....

In localities where highly mineralized water is present in beds above and below the beds that yield the supplies of fresh water it is necessary to be able to locate leaks in wells in order to know whether the wells are being contaminated through holes in the casings or whether...

Geological report on water conditions at Platt National Park, Oklahoma
Charles Newton Gould, Stuart Leeson Schoff
1939, Open-File Report 39-14
Platt National Park, located in southern Oklahoma, containing 842 acres, was established by Acts of Congress in 1902, 1904, and 1906. The reason for the setting aside of this area was the presence in the area of some 30 'mineral' springs, the water from which contains sulphur, bromide, salt, and other...
