INLAND FISHERIES. 5 



line biology, and this ])articulai' structure, tlie tirst of its kind yet 

 built, is emineiitly satisfactory. It lias beeu the object of no little 

 interest in outside (|uarters, and a description of it was sent by 

 request to the Fisheries Commission in New Zealand, 



The old house-boat, which did g-ood service during the previous 

 season, was laid up on the beach and will not float again. It has 

 been in commission throughout the summer as an accessory labo- 

 ratory and quarters for two assistants and has served as a store- 

 house during the winter. 



The naphtha launch " Athleen," 26^ feet long, fitted with a 

 4-horse-power Murray and Tregartha engine, was purchased in 

 Boston, and Avas launched at Wickford June 27. It is an excel- 

 lent boat and has l)eeu of great practical service in locating fish- 

 traps, in collecting clams and scallops, in exploring the shore in 

 various parts of the bay, and in light dredging-. A small, well- 

 built tender was bought with the launch and is so light that it 

 can easily be taken on board. 



The small lobster hatchery which served as a house-boat on the 

 Kickemuit river in 1898 and 1899 was not in commission during 

 the past season. It may be possible to use it during the coming- 

 season however, now that the launch provides means of communi- 

 cation with the headquarters at Wickford. 



Your commission recalls with pleasure the reception its in- 

 vestigations have met Avith outside the State. For two years 

 the commission has been in correspondence with the Imperial 

 Fisheries Bureau of Japan in regard to all these researches. The 

 paper on the " Peridinium and Red Water in Narragansett Bay" 

 has beeu translated into Japanese, at the request of Mr. K. 

 Nishikawa of that bureau. The special interest of the Japanese 

 in " Peridinium " was due to the fact that a smilar phenomenon of 

 "red water" occurred in Japanese waters, caiised b}^ an organism 

 thought at first to be indentical with our form, but later found to 

 belong to a related genus. The two papers on the " Natural His- 

 tory of the Star-Fish " have beeu reprinted in the Bulletin of the 

 U. S. F. C, by request of that commission.
