28 REPORT OF COMMISSIONERS OF INLAND FISHERIES. 



VII. A Continued Investigation of the Life History of the 

 Clam; Methods of Artificial Propagation and Cul- 

 tivation. 



This investigation has been actively continued, and is beginning 

 to produce practical results. Among the new results of the past 

 year is the production of the first crop of clams raised from the seed, 

 and the discover}^ and application of an accurate and simple method 

 of marking clams which are to be transplanted so that individual 

 specimens can be identified and their growth accurately measured 

 at any later period. 



The following special report is a summary of the work of your 

 commission on this subject, and includes the details of the experi- 

 ments of the past season.
