Part I—History and activities of the section of geophysics of the United States Geological Survey
F.W. Lee
1939, Eos, Transactions, American Geophysical Union (20) 280-291
From the beginning of time, all ingenuity of mankind has been concentrated upon the methods of finding gold and unusual deposits in the earth. An illustration (Fig. 1) from the old treatise by Agricola, “De Re Metallica,” published in 1580, will serve to show the implicit faith of that generation...
Report of the committee on underground waters, 1938–39
David G. Thompson
1939, Eos, Transactions, American Geophysical Union (20) 545-555
In preparing the report of the Committee on Underground Waters of the Section of Hydrology for the final year of the triennium, it becomes evident that the collection of fundamental data relating to the hydrology of underground waters continues at a rate comparable to that maintained in the past few...
Relation of fall stream‐flow to spring runoff
H.C. Eagle
1939, Eos, Transactions, American Geophysical Union (20) 117-221
In the prediction of spring runoff from precipitation‐records or snow‐surveys, one of the factors which seems to require consideration is the amount of water held in ground‐storage. The determination of the quantity of water in ground‐storage is a difficult problem involving soil‐sampling, measurements of ground‐water wells, and measurements of the...
Report of the committee on chemistry of natural waters, 1938–39
C. S. Howard
1939, Eos, Transactions, American Geophysical Union (20) 609-611
The membership of this Committee is as follows:C. S. Howard (Chairman), United States Geological Survey, Washington, D.C.I. A. Denison, National Bureau of Standards, Washington, D.C.W. P. Kelley, 119 Hilgard Hall, University of California, Berkeley, CaliforniaA. C. Lane, 22 Arlington Street, Cambridge, MassachusettsC. S. Scofield, Bureau of Plant Industry, United States...
Ground‐water problems in the Southern High Plains
Walter N. White
1939, Eos, Transactions, American Geophysical Union (20) 32-35
The High Plains region has been passing through a prolonged low in the precipitation‐cycle during a large part of the last decade. The drought has continued longer and has been more severe than any that has been experienced since the region began to be farmed. It has caused untold distress....
Some general observations of physiographic and climatic influences on floods
W. G. Hoyt, W. B. Langbein
1939, Eos, Transactions, American Geophysical Union (20) 166-154
The magnitude of flood‐runoff and the degree to which it concentrates in river‐channels with respect to time is known to vary within wide limits. To a considerable extent these variations relate to the physiographic and edaphlc features of the drainage‐basins as they have been developed by the geologic and climatic...
Part II—Geophysical investigations in the Hawaiian Islands
J.H. Swartz
1939, Eos, Transactions, American Geophysical Union (20) 292-298
During 1938 and 1939, an extensive series of geophysical surveys, employing both resistivity and magnetic methods, have been carried on in the Hawaiian Islands by the Section of Geophysics of the United States Geological Survey in cooperation with the Division of Ground‐Water of the Survey and the Division of Hydrography...
Report of committee on glaciers, April 1939
Francois E. Matthes
1939, Eos, Transactions, American Geophysical Union (20) 518-523
The Committee on Glaciers at present is constituted as follows:Harry Fielding Reid—Professor‐Emeritus of Geology, Johns Hopkins University (former member of the International Glacier Commission), 608 Cathedral Street, Baltimore, MarylandWilliam H. Hobbs—Professor‐Emeritus of Geology, University of Michigan (until recently Vice‐ President of the International Glacier Commission, at present associate member), Ann...
The measurement and computation of flood‐discharge
Carl G. Paulsen
1939, Eos, Transactions, American Geophysical Union (20) 177-187
The Geological Survey has been engaged for more than 50 years in measuring and publishing the discharge of streams of the United States. Measured discharges have ranged in quantity from a small fraction of a second‐foot measured volumetrically to more than 2,000,000 second‐feet measured by use of the current‐meter equipment...

Sienna ("ocher") deposits of the Cartersville District, Georgia
Thomas L. Kesler
1939, Economic Geology (34) 324-341
Sienna ("ocher") deposits in the Cartersville district, Georgia, occur in the contact zone between dolomitic limestone and underlying quartzite of Lower Cambrian age. These rocks, together with interbedded schists, were folded and recrystallized probably near the close of Paleozoic time. Simple fissures and transverse and oblique faults, formed during the...

Manganese in a thermal spring in west-central Utah
E. Callaghan, Harold E. Thomas
1939, Economic Geology (34) 905-920
The hot spring north of Delta, Utah, is of particular interest because it has yielded commercial manganese ore; 715 tons of manganese oxide ore that averaged 20% manganese and 0.26% sulphur is recorded. The deposits occur as a thin bed and as lenses and nodules in a dome about 1,600...
