In September the laboratory sustained considerable damages from 
wind and a tidal wave which swept the grounds, flooding the basement 
of the hatchery and the residence and destroying the seawall and pier. 
No serious damage was done to the floating equipment or to the 
scientific apparatus. 
BEAUFORT, N. C. 
Research facilities for the study of marine fishery problems in the

sisted of experiments and studies with reference to oyster culture; 
destruction of oysters by starfish; the propagation of diamond- back
