The age, growth, and feeding habits of the whitefish Coregonus clupeaformis (Mitchell), of Lake Champlain
John Van Oosten, Hilary J. Deason
1939, Transactions of the American Fisheries Society (68) 152-162
This study is based on 120 whitefish collected in northern Lake Champlain (Missisquoi Bay) in 1930 and on 175 whitefish taken in southern Lake Champlain in 1931. Since the whitefish population had not been exploited commercially after 1912 in United States waters and after 1915 in Canadian waters, its study...
Treat - think - and be wary, for tomorrow they may die
F. F. Fish
1938, Progressive Fish-Culturist (5) 1-9
For some very strange reason it is easy to minimize the villian's role, played by disease-producing organisms, in the theater of modern fish culture. Much concern is felt over the food bills footed each month by the hatcheries, but very little is thought about the dead fish which are picked...
Precipitation and vegetation
Ralf R. Woolley, J.C. Alter
1938, Eos, Transactions, American Geophysical Union (19) 804-807
As time marches on, historians are usually quite faithful in recording the activities of man, and it will usually be found that Mother Nature is even more meticulous in reflecting and preserving her experiences, more especially with regard to climate and vegetation. Just how much the activities of man have...
On the estimation of temperatures at moderate depths in the crust of the Earth
C. E. Van Orstrand
1937, Eos, Transactions, American Geophysical Union (18) 21-33
The modern deep well makes it possible to determine the temperatures of the rocks to depths exceeding two miles, and the rock‐samples obtained at these great depths enable the geologist to estimate the depths to the deeply buried basement‐rocks to a rather high degree of precision. The latter estimates are...
Mode of igneous intrusion in La Plata Mountains, Colorado
E.B. Eckel
1937, Eos, Transactions, American Geophysical Union (18) 258-260
The La Plata Mountains, in southwestern Colorado, have long been known as an example of a mountain group of the laccolithic type, although it has been recognized that the igneous geology was much more complex than that of typical laccoliths. A restudy of the ore‐deposits of the District, now in...
Founders of fish culture - European origins
F. F. Fish
1936, Progressive Fish-Culturist (16) 8-10
Just where true fish culture appeared in history depends entirely upon what one considers fish culture to be. If the transportation of fishes from regions of plenty to those of few is to be regarded as fish culture - as it is by some even today - then this story...
Supplementary report on the ground-water supplies of the Atlantic City region
Henry C. Barksdale, Raymond W. Sundstrom, Maurice S. Brunstein
1936, Special Report 6
This report is the second progress report on the ground-water investigations in the Atlantic City region. Many important problems still remain to be solved, however, and it is in no sense a final report. The report covers the area immediately surrounding Atlantic City, extending from Brigantine to Sea Isle City along...

Net selectivity on the Great Lakes
John Van Oosten
1936, Gold Medal Netting News (10) 2-3
Two experiments, using 784 bobwhite quail chicks, were conducted at the Patuxent Research Refuge, Bowie, Maryland, to find a growing diet that would meet wartime restrictions. In 1941 a diet containing 14 per cent sardine fish meal was formulated and gave satisfactory results from the standpoints of survival and growth....
Gold-quartz veins south of Libby, Montana
Russell Gibson
1934, Circular 7
The area described in this paper is one of rugged mountains, composed chiefly of folded and faulted sedimentary rocks of the Belt series. In the nearby region the beds are intruded by diorite sills and granitic stocks. Glacial drift, including silt deposited in a lake, covers much of the lower...
Guidebook of the western United States: Part F - The Southern Pacific lines, New Orleans to Los Angeles
Nelson Horatio Darton
1933, Bulletin 845
The Southern Pacific Railroad from New Orleans to Los Angeles, a distance of about 2,000 miles, passes through a region exhibiting a great variety of geographic and industrial conditions. The climate, especially the amount of precipitation, is the most influential factor in causing this variety. The low Coastal Plain of southern...
Metalliferous deposits of the greater Helena mining region, Montana
Joseph Thomas Pardee, F. C. Schrader
1933, Bulletin 842
The ore deposits described in this bulletin are distributed through a region of about 3,000 square miles surrounding the city of Helena, Mont. In general the surface of this region is mountainous, but it includes several large intermontane valleys. Large areas in the northern and eastern parts of the region...
Ground water supplies of the Camden area, New Jersey
David G. Thompson
1932, Report
This report is one of several setting forth the results of investigations as to the safe yield of the principal water-bearing formations in certain parts of New Jersey, carried on cooperatively by the New Jersey Department of Conservation and Development and the United States Geological Survey. Other areas in which...
A preliminary report on the artesian water supply of Memphis, Tennessee
F. G. Wells
1932, Water Supply Paper 638-A
Memphis is located in the part of the Gulf Coastal Plain known as the Mississippi embayment. It is underlain by unconsolidated sand and clay formations of Tertiary and Cretaceous age. The Wilcox group, of Tertiary age, and the Ripley formation, of Cretaceous age, are excellent aquifers, and all the water...
Potash brines in the Great Salt Lake Desert, Utah
T. B. Nolan
1927, Bulletin 795-B
During and immediately after the war the brines of the Salduro Marsh, in the Great Salt Lake Desert, were a source of considerable potash for the domestic supply. Although no potash has been produced from these brines in the last few years, a continued interest in the area has been...
Shore phases of the Green River formation in northern Sweetwater County, Wyoming
Wilmont H. Bradley
1926, Professional Paper 140-D
For the last two years the writer has been engaged in a detailed study of the Green River formation and its oil shale. In order to arrive at an intelligent interpretation of this great series of lacustrine beds, the field study has been focused upon the marginal phases of the...
The molluscan fauna of the Alum Bluff group of Florida, Part II, Astartacea, Carditacea, Chamacea
Julia Gardner
1926, Professional Paper 142-B
The first of the series of papers upon the Mollusca of the Alum Bluff group covered the orders of the Prionodesmacea and the Anomalodesmacea. The Mollusca were by the beginning of Miocene time so far advances in development that the great majority are included under the highest of the...
The data of geochemistry
Frank Wigglesworth Clarke
1924, Bulletin 770
Upon the subject of geochemistry a vast literature exists, but it is widely scattered and portions of it are difficult of access. The general treatises, like the classical works of Bischof and of Koth, are not recent, and great masses of modern data are as yet uncorrelated. The American material...

The preparation of illustrations for reports of the United States Geological survey : with brief descriptions of processes of reproduction
John L. Ridgway
1920, Report
There has been an obvious need in the Geological Survey o£ a paper devoted wholly to illustrations. No complete paper on the character, use, and mode of preparation of illustration has been published by the Survey, though brief suggestions concerning certain features of their use have been printed in connection...
The Pliocene Citronelle Formation of the Gulf Coastal Plain. The flora of the Citronelle Formation
George Charlton Matson, Edward Wilber Berry
1916, Professional Paper 98-L
In the spring of 1910 the writer, working under the direction of T. Wayland Vaughan, geologist in charge of Coastal Plain investigations, undertook a study of the later Tertiary formations of the Gulf Coastal Plain. According to the plans outlined before the work was begun, the beds that had formerly...
Geology of the pitchblende ores of Colorado
Edson S. Bastin
1915, Professional Paper 90-A
The large amount of public interest that has recently been manifested in radium because of the apparent cures of cancer effected by certain of its emanations makes it desirable to place before the public as promptly as possible all available information in regard to the occurrence of the minerals from...

Geology and underground waters of the Arkansas Valley in eastern Colorado
N. H. Darton
1906, Professional Paper 52
In the valley of Arkansas River in southeastern Colorado there is an area of considerable extent in which artesian flows are available. During the last ten years numerous wells have been sunk to develop this important resource and, in most cases in the lower lands, abundant water supplies have been...
