SUMMARY: A population study of the box turtle (Terrapene c. carolina Linnaeus) was made during the years 1944 to 1947 at the Patuxent Research Refuge, Maryland. A thirty acre area in well drained bottomland forest on the flood plain of the Patuxent River was...
Fifth special report of the Hawaiian Volcano Observatory of the Hawaiian Volcano Research Association and the U.S. Geological Survey: Abrasion hardness
T. A. Jaggar
1950, Report
After reviewing the work of sclerometry, this paper shows that yielding and relative softness are the mechanical basis of what should be called malacometry. The experiments have been made with diamond drills, ring cuts, end millers and grinding wheels.Auerbach's "limited scope of the Mohs list" is quantitatively confirmed. The wear...

Age and growth of the lake whitefish, Coregonus clupeaformis (Mitchill), in Lake Erie
John Van Oosten, Ralph Hile
1949, Transactions of the American Fisheries Society (77) 178-249
Although the whitefish has by no means ranked first from the standpoint of production, it has always been an important commercial species in Lake Erie. Trends in the output of whitefish have differed in the United States and Canadian waters of the lake. The 1893–1946 average annual yield of 1,201,000...
Determination of color of turbid waters
W.L. Lamar
1949, Analytical Chemistry (21) 726-727
A convenient procedure for determining the color of turbid waters, using the principle of precipitation of turbidity by the electrolyte calcium chloride, is described. Because the stable turbidity of many surface waters cannot be completely precipitated by conventional centrifuging alone, this procedure presents a means of flocculating the turbidity without...

Frank W. Jobes
1949, Transactions of the American Fisheries Society (76) 215-247
The longjaw (Leucichthys alpenae) was found at all of the 109 stations fished in the open lake during 1930–1932 and at 29 of the 32 stations in Green Bay in 1930 and 1932. Koelz (1929) found the longjaw at 35 localities, 33 of which were different from those fished in...
New compounds for the control of bacterial gill disease
R.R. Rucker
1948, Progressive Fish-Culturist (10) 19-22
BACTERIAL GILL DISEASE, a common epizootic among hatchery fish, can be controlled by copper sulphate dips, as stated by Davis (1945), or by prolonged treatments with Roccal, as noted by Fish (1947). The use of copper sulphate is not without danger because of variation in toxicity according to the hardness...
The return on the blueback salmon to the Columbia River
Frederick S. Fisher
1948, Scientific Monthly (66) 283-292
THE year 1941 was a crucial one for the blueback salmon of the Columbia River. During that year, one brood came closer to extinction than was realized by more than a few individuals. The immediate causes were not overfishing, hydroelectric power development, or irrigation—although these factors continued to exert their...
Removal of excess nitrogen in a hatchery water supply
R.R. Rucker
1948, Progressive Fish-Culturist (10) 88-90
The water system at the U. S. Fish Cultural Station, Leavenworth, Washington, has been supplemented with two wells that were to be used to increase the temperature of the water during the winter and to cool the Water in the summer if necessary. The well water proved to be unsuitable...
Lava movement at Parícutin Volcano, Mexico
K.B. Krauskopf
1948, GSA Bulletin (59) 1267-1284
The lava flows of Parícutin Volcano, Mexico, offer an exceptional opportunity to study details of lava movement, because many flows are accessible throughout their length and can be watched from their birth to the cessation of their movement. Petrographically the lavas show no significant difference from one flow to another...

J. I. Tracey Jr., H.S. Lapham, J. E. Hoffmeister
1948, GSA Bulletin (59) 861-878
Systematic surveys made at Bikini before and after the atomi bomb tests (Operation Crossroads) in the summer of 1946 afforded an unusual opportunity to examine the reefs and islands of one of the larger atolls of Micronesia. The existing reef appears to be developed on an older surface that extends...
Batholith and associated rocks of Corona, Elsinore, and San Luis Rey quadrangles southern California
Esper S. Larsen Jr.
1948, GSA Memoirs
The batholith of Southern and Lower California is exposed continuously from near Riverside, California, southward for a distance of about 350 miles. In central Lower California it is covered in part by younger rocks, but discontinuous bodies extend to the southern end of Lower California, and hence the batholith is...
Delineation of parallel folds and measurement of stratigraphic dimensions
J.B. Mertie Jr.
1947, Geological Society of America Bulletin (58) 779-802
The delineation of parallel folds in structural sections, and the extraction therefrom of stratigraphic information, has generally been done with considerable personal interpretation. If profiles must be drawn, or sections measured, from structural observations used in pairs, this is unavoidable; but superior results may be obtained if more than two...

P. W. Guild
1947, Eos, Transactions, American Geophysical Union (28) 218-246
Chromite deposits In the Moa district, on the north coast of Oriente Province, Cuba, form one facies of the ultramafic complex in which they occur. Two planar structures, one a compositional layering due to variations in the relative proportions of olivine, pyroxene, plagioclase feldspar, and chromite, and the other a...
Age and growth of the kiyi, Leucichthys kiyi Koelz, in Lake Michigan
Hilary J. Deason, Ralph Hile
1947, Transactions of the American Fisheries Society (74) 88-142
Ages were determined and individual growth histories were calculated from the examination and measurement of the scales of 1,649 kiyis captured at seven localities in Lake Michigan in 1931 and 1932. The numbers of individuals employed for the investigation of other phases of the life history (such as length-frequency distributions,...
Mortality of smelt, Osmerus mordax (Mitchill), in Lakes Huron and Michigan during the fall and winter of 1942-1943
John Van Oosten
1947, Transactions of the American Fisheries Society (74) 310-337
The mortality that nearly exterminated the huge stocks of smelt in Lakes Huron and Michigan during the fall and winter of 1942–1943 appears to have originated in central Lake Huron in the Saginaw Bay area in late September or early October 1942. The mortality spread rapidly northward reaching the Drummond...
Lower Middle Ordovician stratigraphy of the Shenandoah Valley, Virginia
B.N. Cooper, G.A. Cooper
1946, Geological Society of America Bulletin (57) 35-113
In classifying the lower Middle Ordovician of the Shenandoah Valley, the formation names Stones River, Mosheim, Lenoir, Holston, Whitesburg, and Athens have been used without adequate evidence. Detailed study shows that the so-called Athens and Whitesburg, as developed near Harrisonburg, are laterally continuous with the greater part of the Chambersburg...
