1955, Conference Paper, Proceedings of the annual conference of the Southeastern Association of Game and Fish Commissioners
Report of research and findings to date. Topics discussed include: studies on life history and biology of gizzard worm; results of autopsies; experiments on survival and transmission of gizzard worm eggs and larvae in both field and laboratory; persistence of infections; and results of infections in geese of different...
Pesticide toxicity, effects of chlorinated hydrocarbon insecticides upon quail and pheasants
J.B. DeWitt
1955, Journal of Agricultural and Food Chemistry (3) 672-676
Previous studies had shown that heavy or repeated applications of DDT resulted in decreases.in bird populations, but long-range effects of this and other chlorinated hydrocarbon insecticides had not been fully evaluated. Experiments were conducted to determine toxiCitY to quail and pheasants of aldrin, dieldrin, endrin, and strobane, and to...

1955, Water Supply Paper 1330
The early industries in America generally were established when and where demands for the products of industry arose. Most of the early industries were so located that their increasing requirements for transportation, raw materials, market, labor, and water supply could be satisfied economically. Many of these original plant locations have...
Water-power resources in upper Carson River basin, California - Nevada
Harold L. Pumphrey
1955, Water Supply Paper 1329-A
West Fork Carson River offers the best opportunity for power development in the Carson River basin. The Hope Valley reservoir site could be developed to provide adequate storage regulation and concentration of fall would permit utilization of 1,400 feet of head in 51h miles below the clam site, or 1,900...
