Evaporation and runoff from snow in the Alpine Zone of our western mountains
Francois E. Matthes
1938, Eos, Transactions, American Geophysical Union (19) 662
In this informal paper the processes of snow‐wastage at high altitudes were discussed and a number of slides illustrating suncups and sunpits in different stages of development were shown. It was stressed that these features are peculiar to the region above the timber‐line, which biologists term the Alpine, or Arctic‐Alpine, Zone. That regions is,...
Manganese deposits of the Drum Mountains, Utah
Eugene Callaghan
1938, Economic Geology (33) 508-521
More than 15,000 tons of manganese ore has been produced from small deposits in the Drum Mountains in west-central Utah. Lenses of rhodochrosite, now largely weathered near the surface to manganese oxides, lie parallel to the bedding of Cambrian dolomites and shales near faults that are nearly normal to bedding....

Outlook for further ore discoveries in the Little Hatchet Mountains, New Mexico
Samuel Grossman Lasky
1938, Economic Geology (33) 365-389
The Little Hatchet Mountains contain two mining districts, the Eureka silver-lead-zinc district and the Sylvanite gold district, the deposits of each being associated with a mass of monzonite that intrudes Lower Cretaceous sediments. The same formations crop out in both districts, having been duplicated by a large post-ore fault, and...
Third special report of the Hawaiian Volcano Observatory of Hawaii National Park and the Hawaiian Volcano Research Association: Ash formations of the island Hawaii
Chester K. Wentworth
1938, Report
The purpose of the study was to determine the areal extent of the various volcanic ash formations, to describe them petrographically and to develop means of discriminating them. The ash formations, long known in a general way, had been only casually observed by geologists. Their interpretation and separation from other...
Fifty-ninth annual report of the Director of the Geological Survey
Walter Curran Mendenhall
1938, Annual Report 59
Basically important in the general program of conservation and development were the results of the Geological Survey's work during the fiscal year 1938. Investigations of the Nation's mineral and water supplies were conducted with all possible vigor and dispatch, thousands of square miles were surveyed for topographic maps, and technical...

1938, Michigan History Magazine (22) 107-145
Five races of cottontail rabbits belonging to three species occur in Virginia. One of them, the Mearns cottontail (Sylvilagus floridanus mearnsi), is reported here for the first time. It occurs in six southwestern counties of the state, while the eastern cottontail (S. f. mallurus) occurs in the remainder of...
Morphometry of the cisco, Leucichthys artedi (Le Sueur), in the lakes of the Northeastern Highlands, Wisconsin
Ralph Hile
1938, Internationale Revue der Gesamten Hydrobiologie und Hydrographie (36) 57-130
In an earlier study (Hile, 1936) a detailed investigation was presented of the age and growth of the ciscoes of Trout Lake, Musckellunge Lake, Silver Lake, and Clear Lake in northeastern Wisconsin. It was demonstrated that the growth rate of the cisco varies widely from lake to lake within the...
Furunculosis in wild trout
F. F. Fish
1937, Copeia (1) 37-40
Furunculosis, or as it has been more appropiately termed, "fish septicemia," is a disease primarily affecting salmon and trout. It is caused by the invasion and growth of Bacterium salmonicida Emmerich and Weibel, a Gram negative, non-spore forming, diplobacterium belonging to the family Bacteriaceae Cohn. After gaining entrance to the...
