Blood parasites of birds of the District of Columbia and Patuxent Research Refuge vicinity
P.W. Wetmore
1941, Journal of Parasitology (27) 379-393
Recently a number of surveys of blood parasites of birds have been made in different parts of this country by different workers, the general purpose of which was to further the knowledge of the distribution andpathogenicity of these protozoa. This paper treats the distribution of parasites found in sampling miscellaneous...
Notes on the elasticity of the Lloyd sand on Long Island, New York 
C. E. Jacob
1941, Eos, Transactions, American Geophysical Union 783-787
The Lloyd sand is a productive artesian aquifer underlying all of Long Island except the westernmost part. It rests unconformably upon a floor of crystalline rock that slopes toward the southeast at about 100 feet to the mile. Locally the bed‐rock surface has a relief of more than 100 feet....
Ground‐water inventory in the Upper Gila River Valley, New Mexico and Arizona: Scope of investigation and methods used
S.F. Turner, L.C. Halpenny
1941, Eos, Transactions, American Geophysical Union (22) 738-744
The Division of Ground Water of the Geological Survey, United States Department of the Interior, has been making an inventory of the water‐resources of the upper Gila River since January 1, 1940. Funds for the project are furnished under a cooperative agreement with the Arizona State Water Commissioner, supplemented by...
Coefficients of storage and transmissibility obtained from pumping tests in the Houston District, Texas
C. E. Jacob
1941, Eos, Transactions, American Geophysical Union (22) 744-756
An investigation of the ground‐water supply of the Houston District, in Texas, has been in progress since December, 1930, under the general direction of O. E. Meinzer, Geologist‐in‐Charge of the Division of Ground Water of the Geological Survey. The Houston District, as the term is used here, comprises all of...
Fluctuations of water‐level in wells in the Los Angeles basin, California, during five strong earthquakes, 1933–1940
G.A. LaRocque Jr.
1941, Eos, Transactions, American Geophysical Union (22) 374-386
Numerous ground‐water hydrologists have obtained records of water‐level surges in wells during earthquakes and of heightened or lowered levels after those earthquakes. Many of these surges and changes of level are undoubtedly direct effects of the several earthquake‐waves that are recorded on seismographs. Thus, water‐level recorders on observation‐wells promise to...
Report of committee on underground waters, 1940–41
David G. Thompson
1941, Eos, Transactions, American Geophysical Union (22) 948-950
The membership of the Committee during the past year has continued as it was a year ago [see Trans. Amer. Geophys. Union, p. 433, 1940].During a large part of the year, particularly during the last few months, many of the members of the Committee have been engaged in activities more...
Depth of active solution by ground‐waters in the Pecos Valley, New Mexico
Arthur M. Morgan
1941, Eos, Transactions, American Geophysical Union (22) 779-783
The Pecos River Drainage‐Basin is underlain by a thick series of Permian rocks consisting largely of limestone, gypsum (or anhydrite), and halite. The beds have a regional eastward or southeastward dip of 40 to 80 feet to the mile and successively younger beds are exposed at the surface from west...
Ground‐water dams created by faulting of alluvial sediments in the hurricane fault‐zone, Utah
H. E. Thomas
1941, Eos, Transactions, American Geophysical Union (22) 775-778
Ground‐water dams are recognized in the unconsolidated sediments of two intermontane valleys in southwestern Utah. Parowan Valley is about 30 miles long and has a general northeasterly trend; Cedar City Valley lies west and south of Parowan Valley, is somewhat larger, and has a more nearly north‐south trend. Great accumulations...
Report of committee on glaciers, 1940–41
Francois E. Matthes
1941, Eos, Transactions, American Geophysical Union (22) 1006-1011
The personnel of the Committee is now as follows: Harry Fielding Reid, Professor Emeritus of Geology, Johns Hopkins University, 608 Cathedral Street, Baltimore, Maryland; William H. Hobbs, Professor Emeritus of Geology, University of Michigan, Ann Arbor, Michigan; Lawrence Martin, Chief of the Division of Maps, Library of Congress, Washington, D.C.;...
Report of committee on runoff, 1940–41
W. G. Hoyt
1941, Eos, Transactions, American Geophysical Union (22) 1014-1015
The Committee members are the same as last year, namely: H. K. Barrows; Merrill Bernard; E. S. Cullings; R. S. Goodridge; G. A. Hathaway; Joseph Jacobs; F. T. Havis; H. S. Riesbol; Waldo E. Smith; F. F. Snyder; and H. G. Wilm.During the year one addition was made, namely, AURELIO...
The possibility of seiemic measurement of the rotation of the Earth's core
Archie Blake
1941, Eos, Transactions, American Geophysical Union (22) 387-392
The calculations of Inglis show that the rate of transfer of angular momentum to the Earth's (liquid) core may be small enough to permit the axis of rotation of the core to lag about 2° behind that of the rock‐mantle in the precessional motion of the Earth. The travel‐time of...
Factors producing a nine‐year decline in ground‐water levels in Scott County, Kansas
H. A. Waite
1941, Eos, Transactions, American Geophysical Union (22) 772-775
In the south‐central part of Scott County, Kansas, there is an area of shallow water‐table in which the ground‐water levels have declined steadily since 1932 (Fig. 1). In this area water has been withdrawn from wells for irrigation in increasing amounts during the last decade and the precipitation has been...
Factors influencing runoff during the flood of December, 1937, in northern California
W.G. Boyt
1941, Eos, Transactions, American Geophysical Union (22) 124-129
Engineers and hydrologists engaged on flood‐problems throughout much of the United States east of the Rocky Mountains must deal to a considerable extent with wide‐spread storms covering thousands of square miles. The gradations of meteorologic conditions as regard both area and time are relatively homogeneous during such storm‐events and are...

Magnetic studies by the Geophysical Section of the United States Geological Survey
F.W. Lee
1941, Eos, Transactions, American Geophysical Union (22) 460-462
Continued progress has been made in magnetic surveys over large sectional areas by G. R. MacCarthy. Beginning in Florida south of the Okeefenokee Swamp, magnetic traverses were measured and continued through the southern part of Georgia. The most northerly traverses crossed regions where they contacted the crystallines near the surface...
The quicksilver deposits of the Terlingua region, Texas
Clyde P. Ross
1941, Economic Geology (36) 115-142
Texas is second among quicksilver-producing States because of the Terlingua region, in the Big Bend of the Rio Grande. This region contains Cretaceous strata, largely calcareous, which grade upward into Tertiary volcanics, locally without break. The strata are cut by numerous intrusions, largely alkalic, and are extensively folded and faulted.Many...
