PROGRESS IN BIOLOGICAL INQUIRIES, 1936 59 
elsewhere, dealt with the following problems: (1) The biology and 
control of the oyster drill, (2) the life cycle of a sporozoan parasite 
of the oyster, (3) autonarcosis in the oyster and its industrial appli- 
cation, (4) destruction of oysters by a hurricane on the Eastern 
Shore of Virginia, (5) spawning of the blue crab in North Carolina 
waters, and (6) reproduction and feeding of the commercial shrimp. 
The Beaufort laboratory serves as headquarters for oyster investi- 
gations in. the South Atlantic region and has cooperated with the 
conservation departments of the coastal States, the Works Progress 
Administration, and commercial fishing interests in the rehabilitation 
of public oyster beds, regulation of the clam and blue-crab fisheries, 
and continued advice to a cooperative fishermen’s organization. At 
the request of the United States Engineer’s Department an inspection 
was made of the field experiments and studies being conducted by 
them on the South Carolina coast to determine the possible damage 
to oysters by dredging operations in the Intracoastal Waterway. At 
meetings of the National Emergency Council in Raleigh and 
Durham, N. C., reports were presented describing the various activi- 
ties conducted by the Beaufort laboratory for the conservation and 
development of the fish and shellfish resources of this State. 
Laboratory facilities for marine research have been provided for 
15 independent investigators from other institutions who were en- 
gaged in the following studies: Dr. H. V. Wilson, professor in the 
University of North Carolina, research begun at the laboratory the 
preceding summer dealing with the effects of certain narcotics on 
sponge syncytia; Dr. C. E. Tharaldsen, New York Homeopathic 
Medical College, the effect of cancer-producing substances on embry- 
onic development of the sea urchin; Dr. Irene Bolich, Alabama 
College, influence of environmental conditions on cellular behavior ; 
Greer J. Kimery, United States Department of Agriculture, process 
of decomposition in shrimp; J. Albert Fincher, University of North 
Carolina, early development and regeneration in the lower inverte- 
brates; D. John O’Donnell, Ihnois Natural History Survey, marine 
fauna of representative intertidal areas; Dr. Alan Boyden, Rutgers 
College, the blood relationship of animals; Gordon H. Tucker, Uni- 
versity of North Carolina, regenerative powers of the cells of lower 
invertebrates; Dr. Hoyt S. Hopkins, New York University, effects of 
methylene blue on respiration and glycolysis in tissues of lamelli- 
branchs; Dr. George E. Coghill, formerly of Wistar Institute, myo- 
genic behavior in embryonic tissues of fishes; Dr. A. S. Pearse, Duke 
University, studies of the flatworm parasite of the oyster; George W. 
Wharton, Duke University, parasites of the intestinal tract of rep- 
tiles; Dr. R. H. Kudo, University of Illinois, sporozoan parasites of 
molluses; Dr. E. Laurence Palmer, Cornell University, general nat- 
ural history of seashore animals; Dr. Katherine V. Palmer, president 
of the Paleontological Research Institution, living and _ fossil 
molluscs. 
Terrapin culture—Artificial propagation of the diamond-back 
terrapin, conducted in cooperation with the Division of Fish Culture 
and under the immediate supervision of Charles Hatsel, yielded dur- 
ing the summer of 1936 a total hatch of 10,750 young terrapins. 
These were cared for and fed in the special rearing house for a period 
of approximately 2 months during the early fall after which they
