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...
