Harold C. Hanson, Robert H. Smith
1950, Bulletin of the Illinois Natural History Survey (25) 67-210
This Canada goose study is based on data from three primary sources : data collected at Horseshoe Lake, Alexander County, Illinois ; surveys by the authors on the distribution, habitat, and behavior of the population elsewhere in the Mississippi flyway ; and banding records of the Jack Miner Bird Sanctuary,...

Geologic interpretation of seismic data relocation Route 1, cut, Stations 34-52, Copper Mine Road area and northern portion of Ballard Estate in Topsfield, Mass.
James E. May, Daniel Linehan
1950, Open-File Report 50-46-B
Relocation of the Newburyport Turnpike, Route 1, in Topsfield, Mass., will require a long relatively deep cut between stations 34 and 52. In order to obtain preliminary information on the depths to bedrock and on the nature of the subsurface materials at this site, reconnaissance seismic work was performed in...
Geologic interpretation of seismic data relocation Route 2, Littleton Road grade separation stations 243-252 in Harvard, Mass.
James E. May, Daniel Linehan
1950, Open-File Report 50-46-A
During parts of June and July 1949 nine seismic traverses were made at this site. Upon preliminary office development, the velocity data for some of these traverses were though to be inadequate and it was recommended that these lines be re-surveyed. Later surveys (March 1950), however, of nearby sites indicated...
The Leyden uranium prospect, Jefferson County, Colorado
Garland B. Gott
1950, Trace Elements Memorandum 132
The Leyden uranium prospect is in sec. 28, T, 2 S., R. 70 W, Jefferson County, Cplo, Examination of the property was made in February 1950. Uranium was first reported in this locality in 1875 by Captain E. L. Berthoud, who noted uranium minerals associated with the main coal bed....

Geologic interpretations of seismic data relocation Routes 15 and 20 in Sturbridge, Mass.
James E. May, Daniel Linehan
1950, Open-File Report 50-43-D
The proposed improvements at the junction of Routes 15 and 20, Sturbridge, Massachusetts, requires a cut of considerable magnitude for the relocation of east-bound Route 20 between stations 158 and 167. Geologic and seismic studies were made of the site for the purpose of determining the position of the bedrock...

Geologic interpretations of seismic data Route 128 (Northern Circumferential Highway) cut, and Hopkins Street grade separation stations 1-18 in Wakefield, Mass.
James E. May, Daniel Lineham
1950, Open-File Report 50-43-A
The completion of a segment of the Northern Circumferential Highway, Route 126, in Wakefield, Mass., requires an underpass bridge at Hopkins Street, Station 5+50. The plan of the project shows approximately 1800 feet if approach cuts between stations 1 and 18. In October 1945 a preliminary seismic study was made...
The design of the Model V transmission fluorimeter
Mary H. Fletcher, Irving May, Joseph W. Anderson
1950, Trace Elements Investigations 133
The transmission fluorimeter for the measurement of the fluorescence of uranium in fluoride melts is described. The instrument incorporates several improved features which have not been published previously. Unlike the earliest models, the design of the new fluorimeter, with its close machining of parts, reduces the possibility of light leakage...
The volcano letter: A weekly news leaflet of the Hawaiian Volcano Research Association - 1950
1950, Report
The Volcano Letter was an informal publication issued at irregular intervals by the Hawaiian Volcano Observatory (HVO) during the years 1925 to 1955. Individual issues contain information on volcanic activity, volcano research, and volcano monitoring in Hawaii. Information on volcanic activity at other locations is also occasionally included.The Volcano Letter...
Geologic interpretation of seismic data relocation Route 1, stations 150-155 in Danvers, Mass.
James E. May, Daniel Linehan
1950, Open-File Report 50-42-B
At this site the reconstruction of Route 1 requires a deep excavation through a high, east-west elongated hill. In order to obtain subsurface information that would be of aid in selecting the most suitable location for this deep cut through the hill, geologic and seismic studies were made in October...
Geologic interpretation of seismic data relocation of Route 2, Shelburne Falls in Shelburne, Mass.
James E. May, Daniel Linehan
1950, Open-File Report 50-43-C
In June 1945 a seismic study was made for the projected Halligan Avenue out, stations 364-374, Route 2 relocation in Shelburne, Mass. Nine profiles were run at this time and a report on this work was submitted by James E. Maynard and Rev. Daniel Linehan (file report of July 1945)....

Preliminary examination of uranium deposits near Marysvale, Piute County, Utah
Harry C. Granger, Herman L. Bauer
1950, Trace Elements Memorandum 33
Autunite and other uranium minerals were discovered in 1948 by Pratt Seegmiller about 3 1/4 miles north of Marysvale, Piute County, Utah. Mining operations were begun in the summer of 1949 by the Vanadium Corporation of America on the Prospector and the Freedom claims, and by the Bullion Monarch Mining...
Fifth special report of the Hawaiian Volcano Observatory of the Hawaiian Volcano Research Association and the U.S. Geological Survey: Abrasion hardness
T. A. Jaggar
1950, Report
After reviewing the work of sclerometry, this paper shows that yielding and relative softness are the mechanical basis of what should be called malacometry. The experiments have been made with diamond drills, ring cuts, end millers and grinding wheels.Auerbach's "limited scope of the Mohs list" is quantitatively confirmed. The wear...
Geologic interpretation of seismic data relocation route 1: proposed cut at stations 127-135 in Danvers, Mass.
James E. May, Daniel Linehan
1950, Open-File Report 50-43-B
The layout for the reconstruction of the Newburyport Turnpike (Route 1) proposed cit at stations 127-135, in Danvers, Mass., shows a deep cut through the western end of a hill between stations 127 and 135. Because of the depth of this cut seismic work was done at the site in...
Distribution of leached radioactive material in the Legin Group Area, San Miguel County, Colorado
Allen S. Rogers
1950, Trace Elements Memorandum 171
Radioactivity anomalies, which are small in magnitude, and probably are not caused by extensions of known uranium-vanadium ore bodies, were detected during the gamma-ray logging of diamond-drill holes in the Legin group of claims, southwest San Miguel County, Colo. The positions of these anomalies are at the top surfaces of...
Field investigation of airborne radioactivity anomalies in Marquette County, Michigan
Harold L. James
1950, Trace Elements Memorandum 159
The broad radioactivity anomalies recorded by the airborne detector in the vicinity of Republic, Marquette County, Michigan, coincide rather closely with parts of a granitic complex chiefly of Archean age. Ground examination of the rock in these areas of high radioactivity shows that the granitic rock typically yields two to...
The Papsy's Hope autunite prospect, Marysvale District, Piute County, Utah
Edward P. Kaiser
1950, Trace Elements Memorandum 145
The Papsy's Hope autunite prospect is in the eastern part of the Marysvale district, Piute County, Utah, about 1 1/2 miles northeast of the mines now operating. It is developed by two shallow cuts and a short incline shaft. One cut exposes a zone of fractures, sparse quartz veins,...
Modification to Tracerlab Automatic Sample Changer
F.J. Flanegan, J. M. Nelson, J.J. Warr Jr.
1950, Trace Elements Memorandum 142
The U.S. Geological Survey has recently modified the Tracerlab Automatic Sample Changer so that the geometry is greatly improved for counting larger low-activity samples in finely ground form. The larger sample and larger Geiger Mueller tubes allow a greater number of samples to be counted per hour with the same...
