Reconnaissance of radioactive rocks of Maine

The state of Maine was traversed with car-mounted Geiger-Mueller equipment in the late summer of 1948 and the radioactivity of approximately 4,600 miles of road was logged. All samples were analyzed, both in the field by comparing the radioactivity of each sample to the radioactivity of a stranded measured with a simple scaling modification of a portable counter, and in the Geological Survey’s Tr

Reconnaissance of radioactive rocks of Massachusetts

During the 1948 and 1949 field seasons radiometric car traverses were made along the numbered federal and state highways and along many unnumbered roads of Massachusetts. Near Worcester pegmatitic rocks are estimated to contain about 250 pounds of uranium and 8,500 pounds of thoria per foot of depth. Near Southbridge pegmatitic rocks are estimated to contain about 6,500 pounds of thoria per foot

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

IN 1949, while engaged in population studies of birds in northern Maine, the authors accumulated considerable information concerning population dynamics of birds inhabiting the 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.

Report on a pumping test at Evansville, Indiana

The City of Evansville, Ind. has utilized the Ohio River as a source of municipal water supply for many years. The average daily pumpage for the city in 1950 was reported to be about 18.5 million gallons. Because of the extreme variability in the quality of the river water and the extensive treatment necessary, the city considered the possibility of developing a ground-water supply to supplement i
