laboratory record for the summer 1922 contains the names of 19 

 guest investigators working on a great variety of biological prob- 

 lems. Subjects of their inquiry ranged from the studies of diatoms, 

 regeneration of sponges, fish histology, physiology of vision in 

 lobster, parasites of fishes, and haematology of fishes, to the 

 study of the anatomy and genetics of the fruit fly. The Bureau 

 biologists were engaged in two research projects: hydrographic 

 and biological survey of Long Island Sound conducted by P. S. 

 Galtsoff (recently appointed Naturalist of the Albatross) and sea- 

 sonal variations in the composition of plankton of Woods Hole 

 waters by Charles J. Fish (instructor in embryology at Brown 

 University and aquatic biologist of the Bureau). The Woods Hole 

 station was used as a base for the operation of the U. S. S. Fish 

 Hawk in Long Island Sound. 



One of the guest investigators. Miss Marie Dennis Poland, 

 began a study of the methods of identifying fish eggs and larvae. 

 In 1923 she continued the work as field assistant of the Bureau. 

 And in 1924, while still working with Charles J, Fish on the iden- 

 tification of larval fishes found in plankton, joined him in matri- 

 mony. The team of Charles and Marie Fish became well known 

 to the biological community of Woods Hole as a couple deeply de- 

 voted to marine research. The paper describing the seasonal 

 distribution of plankton of Woods Hole region (Fish, 1925), sum- 

 marizes the observations made from samples collected through- 

 out the years by the simple device of suspending a large plankton 

 net from the corner of the wharf where the tides kept it in a hori- 

 zontal position for several hours. 



R. E. Coker resigned his Bureau position in 1923 to be- 

 come Professor of Zoology in the University of North Carolina 

 at Chapel Hill. He continued, however, as a summer Director 

 of the Laboratory from June 22 to September 8. Among the tem.- 

 porary appointees of the Bureau were Charles B. Wilson, work- 

 ing on the collection of copepods of Chesapeake Bay; Paul Visscher 

 of Johns Hopkins University, studying the nature and extent of 

 ship's fouling with special reference to biological aspects (Visscher, 

 1928); James I. Penney, working on the biology of the wood des- 

 troying crustacean Limnoria. The scope of research, as in 

 previous years, covered a very wide range of problems; from the 

 diatom flora of Woods Hole, by Paul S. Conger of the Carnegie 

 Institution in Washington, to structural development of oral glands 

 of snakes by Albert M. Reese, Professor of Zoology of West 

 Virginia University. A considerable part of the Laboratory space 

 on the second floor was occupied by N. A. Cobb, nematologist 

 of the Department of Agriculture in Washington, and his assistants. 



The laboratory and living accommodations of the Woods 

 Hole Station were used to their full capacity in 1923. Every work- 

 ing table and every room in the residence were occupied. It was 

 a policy of the Bureau of Fisheries to encourage biological research
