ment and a few other workers. Dr. J. P. Visscher is conducting 

 here experiments in connection with his study of the nature and 

 extent of the fouling of ships' bottoms. 



At the Key West (Fla.) biological station little work of a scien- 

 tific nature has been possible. The lack of a laboratory building is 

 mainly responsible for this, and it is hoped that adequate facilities 

 for conducting investigations may be provided in the near future. 

 The director, Isaac Ginsberg, has succeeded admirably in improving 

 the condition of the grounds, which are now considered to be the 

 equal of any in Key West. As opportunities were presented, collec- 

 tions of the local aquatic fauna and observations on the fish and 

 fisheries were made. 



The work of the biological laboratory at Fairport, Iowa, has been 

 frequently mentioned in the preceding pages. This station is the 

 center from which investigations relating to fresh-water mussels 

 and the fishes of the Mississippi Valley are conducted. During the 

 summer months the laborator}^ was open to independent workers, 

 and at various times during the year special investigations by reg- 

 ular employees were made here. The director, R. L. Barney, 

 resigned during the year. T. K. Chamberlain has been appointed 

 acting director, and has been materially aided in the work by the 

 advice of Dr. E. P. Churchill, of the University of South Dakota. 

 H. Walton Clark and Chester N. Blystad, scientific assistants con- 

 nected with the Fairport laboratory, also resigned during the year. 



In addition to the regular work of the laboratory-, aid and advice 

 has frequently been given by the scientific staff to various govern- 

 mental and private organizations in matters pertaining to the con- 

 servation of the fisheries. Conferences have been attended and sur- 

 veys made. The work of the station enjoys the confidence of those 

 primarily interested in the commercial fisheries and the aid and 

 support of scientists in the Middle Western States.
