Wood mouse and box turtle populations in an area treated annually with DDT for five years
A 117-acre area of dense woodland on the Patuxent Research Refuge received an aerial application of DDT in oil at the rate of 2 pounds per acre gnnually for five years. DDT reached ground level in a much smaller amount (thousandths to hundredths of a pound per acre). Treatment was made during the first week of June of each year from 1945 through 1949.

Distinctions between the snake genera Contia and Eirenis
Summary: Various workers have believed Contia to be related to or congeneric with either or both Sonora and Eirenis, the latter a genus of Western Asia.

Removal and repopulation of breeding birds in a spruce-fir forest community

This information was obtained in connection with investigations of the effective control by breeding birds of an infestation of the spruce budworm, Choristoneura fumiferana Clem.

Effects on wildlife of DDT used for control of Dutch elm disease
During the summer of 1949 studies were conducted at Princeton, New Jersey, to determine the effects on wildlife of DDT used in the control of Dutch elm disease. Direct mortality was determined by intensive search for dead birds after spraying. Twenty-six songbirds, one bat, and one gray squirrel were found. Of 11 dead birds from a study area of approximately 20 acres only one was an adult. S
