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....
Investigation of coal deposits in the Fairview and Coal City basins, Coosa Field, St. Clair County, Ala.: reserves, petrography, and chemical properties of coals: washability characteristics of coal from Fairview bed: geology of area
Albert L. Toenges, Louis A. Turnbull, Theodore R. Jolley, Joseph J. Shields, H.L. Smith, H. J. O’Donnell, H.M. Cooper, R.F. Abernethy, B.W. Gandrud, H.L. Riley, Howard E. Rothrock
1949, Technical Paper 719
Report issued by the Bureau of Mines discussing the coal deposits in Saint Clair County, Alabama. Investigations of the estimated reserves and analyses of the coal fields in this area are presented. This report includes tables, maps, illustrations, and photographs....
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...
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...
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. III. Advanced studies in the evaluation of chemical repellents
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...
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...
