Spectrographic analysis of coal and coal ash
R.G. Hunter, A.J.W. Headlee
1950, Analytical Chemistry (22) 441-445
Coal can be analyzed on the spectrograph for per cent ash and composition of ash in a matter of a few minutes, using the total energy method. The composition of the ash so determined can be used to calculate ash softening temperatures. This analysis can be made in sufficiently short...

Various sulfonamide treatments of furunculosis in brook trout, Salvelinus fontinalis
S. F. Snieszko, J.S. Gutsell, S. B. Friddle
1950, Transactions of the American Fisheries Society (78) 181-188
Sulfamerazine, sulfamethazine, sulfathiazole, and sulfamerazine alternated at 4‐day intervals with sulfathiazole, were compared in the treatment of furunculosis among yearling and fingerling brook trout at the Leetown Station of the U. S. Fish and Wildlife Service, Kearneysville, West Virginia, in 1947. The daily dosage rates were: for sulfamerazine and...
A contribution to the etiology of ulcer disease of trout
S. F. Snieszko, S. B. Friddle
1950, Transactions of the American Fisheries Society (78) 56-63
During the fall of 1947 and the late summer of 1948, outbreaks of ulcer disease occurred among brook trout fingerlings at the Leetown station and other hatcheries. From the ulcers, blood, and kidneys of the diseased trout were isolated bacteria which could be successfully cultivated only on media to...

1949, Geological Investigations, Naval Petroleum Reserve No. 4, Alaska 9
Recent interest in the anticlines near the headwaters of the Utukok River has prompted the issuance of two special reports. This, the first of the two reports, deals with the Driftwood anticlines, the second will consider the Awuna anticline and the western part of the Carbon Creek anticline.At present, only...
Fact and fiction in spawntaking: Addenda

Geology of the Roswell artesian basin, New Mexico, and its relation to the Hondo Reservoir and Effect on artesian aquifer storage of flood water in Hondo Reservoir
Robert T. Bean, Charles V. Theis
1949, Technical Report 9
In the Roswell Basin in southeastern New Mexico artesian water is produced from cavernous zones in the carbonate rocks of the San Andres formation and the lower part of the Chalk Bluff formation, both of Permian age. The Hondo Reservoir, 9 miles west-southwest of Roswell, was completed by the U....

Ecology of a nesting red-shouldered hawk population
R. E. Stewart
1949, The Wilson Bulletin (61) 26-35
An ecological study of a nesting Red-shouldered Hawk population was made over a 185 square mile area on the Coastal Plain of Maryland in 1947. The courting and nesting season extended from late February until late June.....During the nesting season a combination of fairly extensive flood-plain forest with adjacent clearings...
Wildlife effects of DDT dust used for tick control on a Texas prairie
J.L. George, William H. Stickel
1949, American Midland Naturalist (42) 228-237
The effect of DDT dust on wildlife was studied at Camp Bullis, Bexar County, Texas, in the summer of 1947. Studies were made on a 206.6 acre plot that was treated with DDT for experimental control of the Lone Star tick (Amblyomma americanum). A dust consisting of one part of...
Calcium and phosphorus requirements of breeding bobwhite quail
J.B. DeWitt, R. B. Nestler, J.V. Derby Jr.
1949, Journal of Nutrition (39) 567-577
In the course of studies designed to determine the calcium and phosphorus requirements of breeding bobwhite quail, it was found that best results were obtained when the Ca/P ratio in the diet was approximately 2.3:1. Variations in the Ca/P ratio produced significant differences in results when the level...
Rodent-repellent studies. I. Method for the evaluation of chemical repellents
E. Bellack, J.B. DeWitt
1949, Journal of the American Pharmaceutical Association (38) 109-112
A biological assay procedure and a method for the numerical expression of results have been devised for the determination of the repellency to rodents of different chemical compounds. The procedure is based upon the degree of acceptability of foods containing the candidate repellents, and has been shown to offer a...

E. Bellack, J.B. DeWitt
1949, Journal of the American Pharmaceutical Association, Scientific Edition (39) 197-202
In order to bridge the gap between preliminary screening of chemicals for potential rodent repellency and the application of these compounds to paper cartons, more advanced studies in the evaluation of promising materials have been carried out. These studies have resulted in: (1) a modification of the food acceptance technique...
