gard private fish raising as a matter of great importance in view 

 of the widespread practice in America of polluting public waters. 

 It is now considered by fishery officers that the continued pollution 

 of our streams is rendering ineffective much of the important 

 work of public fish propagation. 



The Acjuarium has been brought into close relation with thi'? 

 work through its fish-hatching exhibit, its large collections of liv- 

 ing food fishes and its correspondence with the public at large. 

 Another publication emanating from the Aquarium, entitled "The 

 Pollution of Streams," has also been widely reprinted. 



AID TO SCHOOL TEACHERS. 



Small marine aquaria have been placed in more than 300 school 

 houses in the city, the aquaria being furnished by the Board of 

 Education, the animal collections by the Xew York Aquarium. 



The work requires but a portion of the time of a single env 

 ployee, while the animal life is supplied by the collector in con- 

 nection with his regular field work. The furnishing of the ma- 

 terial for school aquaria is thus only a nominal cost to the 

 Aquarium. 



Classes in biology accompanied by teachers continue to visit 

 the Aquarium Laboratory where there are facilities for observ- 

 ing the smaller forms of marine- and fresh-water life. 



The number of pupils and teachers thus accommodated dur- 

 ing the year was 5,218, and the number of school aquaria stocked 

 was 86. This work has been under the personal supervision of 

 Mr. Spencer of the Aquarium staff. 



hitcniatioiial Fislicrics Cojii^rcss. — On the forenoon of Septem- 

 ber 28 the Fourth International Fisheries Congress, meeting for 

 the first time in the United States, was specially entertained at the 

 Aquarium. Most of the foreign delegates were surprised to find 

 that New York maintained a distinctly larger and better-stocked 

 aquarium than is to be found anywhere in Europe. It collects 

 and succeeds in keeping aquatic forms, the exhibition of which 

 is not attempted elsewhere. The Congress, after a very active 

 meeting in Washington, spent a day in Xew York and then 

 visited the principal fishing centers of Xew England. Delegates 

 were present representing many countries. A splendid scries of 

 papers was presented relative to the ])romotion of fishery indus- 

 tries, the conservation of fishery resources, international hsherv 

 regulation, fish culture and biological research.
