R.T. Mitchell
1950, Annals of the Entomological Society of America (43) 249-261
This paper is a revision of the known species of A croricnus of America. Of the five previously described species assigned to this genus from this area, four are reduced to subspecific rank under the European genotype, A croricnus stylator (Thunberg). Three subspecies and one species are described as new, and typical stylator is recorded from...

A comparative study of mean-section and mid-section methods for computation of discharge measurements
Kenneth B. Young
1950, Open-File Report 53-277
In February, 1949, Mr. J. V. B. Wells, Chief of the Surface Water Branch, appointed a committee of three hydraulic engineers assigned to the Washington office to make a comparative study of the relative merits of the mean-section and mid-section methods of computing discharge measurements. this was done in order...
Geologic interpretations of seismic data: Braintree-Weymouth by-pass stations 29-56, Liberty Street grade separation in Braintree, Massachusetts
James E. May, Daniel Linehan
1950, Open-File Report 50-42
At the request of the Massachusetts Department of Public Works, seismic and geologic studies were made for the projected Braintree-Weymouth By-Pass grade separation at Liberty Street in Braintree, Massachusetts. The work was performed in order to furnish data that would aid the engineers in preparing estimates of the quantity of...

Geologic interpretation of seismic data, relocation Route 1 cut, Stations 25-36 Ballard Estate in Topsfield, Mass.
James E. May, Daniel Linehan
1950, Open-File Report 50-45
This investigation was undertaken to determine the surface and subsurface conditions between stations 25 and 36 of the proposed relocation of the Newburyport Turnpike, Route 1, Topsfield, Mass. Reconnaissance seismic work was performed at the site in September 1949. Because that work showed bedrock near the surface over an extensive...

Geologic interpretations of seismic data, relocation of Route 116, Stations 7-135 in Cheshire, Mass.
Max E. Willard, Daniel Linehan
1950, Open-File Report 50-52
Three segments of the proposed relocation of Route 116, stations 7 to 135, in Cheshire, Mass. require shallow cuts. For the purpose of obtaining information on the depths to bedrock, and on the nature of the overlaying materials, seismic and geologic studies were made of the segments in October 1949....
