gun by Dr. C. A. SLore and later continued by 

 Mr. Hay, has been nearly completed and wiU 

 probably go to press at an early date. 



Dr. H. S. Davis, of the University of 

 Florida, devoted the two seasons to the con- 

 tinuation and completion of investigations on 

 the Myxosporidian parasites of fishes occur- 

 ring in the Beaufort region. The parasites are 

 common in nearly all the fishes of the region. 

 There is in fact scarcely a species which is not 

 infested by one or more species. The results 

 of these investigations have been embodied in 

 a paper on the Myxosporidia of the Beaufort 

 Region, which is nearly ready for publication. 



Dr. James J. Wolfe of Trinity College, Dur- 

 ham, N. C, during both seasons under con- 

 sideration continued his experiments on the 

 brown alga, Padina, and the examination of 

 the Diatomaceae of the Beaufort region. It is 

 expected that a paper covering the results of 

 the experiments on Padina will soon be pub- 

 lished. Dr. Wolfe is preparing a rather ex- 

 tensive and profusely illustrated report on 

 the diatoms. Many microphotographic plates, 

 which were retouched by the artist, have al- 

 ready been prepared. 



Dr. L. F. Shackell, of the St. Louis Uni- 

 versity School of Medicine, continued his ex- 

 periments begun in 1912 on the preservation of 

 wood against marine borers. During the past 

 two seasons these studies were carried on in 

 collaboration with the staff of the U. S. For- 

 est Products Laboratory, Madison, Wisconsin. 

 A special study was made of the toxicity of 

 coal-tar creosote and its fractions for certain 

 borers. During the season of 1914 the com- 

 mon ship worm, Xylotrya, was used in the ex- 

 periments, and during 1915 the common wood- 

 boring crustacean, Limnoria, was used in the 

 same series of experiments. The results were 

 about the same for each. The results of the 

 1914 experiments have already been recorded 

 in the Proceedings of the American Wood 

 Preservers' Association for 1915. During the 

 summer of 1915 specimens of wood treated 

 with various coal-tar creosote preparations 

 were exposed to the water of the harbor. These 

 specimens are, of course, to be carefully ex- 

 amined in order to determine the effectiveness 

 of the different treatments. 



Dr. William L. Dolley, Jr., of Eandolph- 

 Macon College, began in 1914 an investigation 

 of the copepods of the Beaufort region. Col- 

 lections were made and forms occurring most 

 frequently were identified. Unfortunately Dr. 

 Dolley's work was greatly interrupted by sick- 

 ness. Dr. Dolley was unable to return for the 

 continuation of this work during the summer 

 of 1915. 



Dr. 0. H. Edmondson, now of the Univer- 

 sity of Oregon, formerly of the University of 

 Iowa, continued during the summer of 1915 

 the collection and identification of the fora- 

 minifera of the Beaufort region. During the 

 past season over two hundred species were col- 

 lected and provisionally identified and taken to 

 the university for further study. 



Mr. Radcliffe, of the Bureau of Fisheries, 

 Washington, D. C, was at the laboratory dur- 

 ing the summer of 1914. He continued the 

 work of the report on the sharks and skates of 

 the Beaufort region and had charge of the 

 work done by the Fish HawTc during its stay in 

 the vicinity. 



Professor O. W. Hyman, of the University 

 of Tennessee, during the summer of 1915 made 

 some investigations regarding the artificial 

 propagation of the common clam, Yenus mer- 

 cenaria. It was, however, determined that the 

 spawning season was nearly over, and that this 

 work should be undertaken earlier in the sea- 

 son, e. g., probably as early as April. Mr. 

 Hyman also worked on the early larval forma 

 of certain decapod crustaceans of the Beau- 

 fort region. Of ten forms the first zogas were 

 secured, in six of them the second zoeas and in 

 three the third zceas were secured. The method 

 of procedure in each case was to get a ripe 

 female with eggs and keep her in the labora- 

 tory until the eggs hatched. Each stage of the 

 zcea was described and drawn with camera 

 lucida. 



Mr. Arthur Jacot, of Cornell University, 

 spent the season of 1915 at the laboratory mak- 

 ing a study of the mullets of the vicinity with 

 especial reference to their spawning habits and 

 the young, or Querimanna stage. It had been 

 noticed by the director that young of one inch 

 and less in length could be obtained throughout 

 the year. It had also been reliably reported by
