20 INLAND FISHERIES. 



while exploring- the shore, dredging- the bottom, and skimming- the 

 surface of the water are l)eiug- filed for future use, and a daily 

 record of the temperature and specific g-ravity of the water at the 

 house-boat in Wickford was kept from April to the middle of 

 September. 



yil. A Preliminary Survey of the Shore of the Bay for the 

 Purpose of Determining Those Portions "Which are 

 Most Productiye of Young Seed-Clams. 



The fact that clams set exceeding-ly thick in limited localities so 

 that they can be taken in quantities, and the importance of this 

 fact in connection with the clam-industry, has been pointed out in 

 the report of last spring- and is also referred to in the jjresent re- 

 port. 



After the arrival of the launch a larg-e portion of the shore of 

 the bay was examined for the purpose of locating- such plaices. 

 Several localities were discovered, although it was evident that, 

 in g-eueral, the set of the past year was far less abundant than that 

 of 1899. It is proposed to continue the examinations of the shore 

 for this and other purposes, and to embody the results in a future 

 report. 



VIII. A Continuation of the Investigation on the Life-History 

 OF the Clam, Methods of Artificial Propagation and 

 Cultivation. 



This investigation has been continued at the laboratory at 

 Wickford, and some of the questions left OYer from last year have 

 been satisfactorily answered. The commission is indebted to the 

 IT. S. Fish Commission for assistance in many of the experiments, 

 the report of which is given in the following pages :
