Experiment No. 9. — This past summer the clams again set abund- 

 antly on the southernmost point of Cornelius Island, Wickford. On 

 August 12 a square foot produced 4,264. An average plot was 

 selected from which clams were secured at various intervals through- 

 out the fall. The excessive crowding must, of course, be borne in 

 mind in considering the following table of the average length of these 

 clams at rather regular intervals. 



75 to 100 used for average.
