LARKINS ROCK. 



This is a small bed in Nansemond River at the extreme southwest 

 corner of Public Ground No. 2. As developed by the survey it has 

 an area of about 39 acres and a depth varying from 4 J to 8 feet at 

 mean-low water. It is stated that the product of this bed has been in 

 demand by shucking houses, the size and quality being generally 

 good and the condition fat, especially early in spring. The market 

 oysters found by the survey averaged between 300 and 350 to the 

 bushel and the small oysters about 750 per bushel. 



The bed at present bears market oysters at the average density of 

 about 5 bushels per acre, though in spots the production is as high as 

 18 bushels. The young growth has an average density of about 10 

 bushels and a maximum of 31 bushels per acre. 



At the present time this bed must be regarded as depleted, as at 

 none of the spots examined could a man tong more than 2 bushels of 

 oysters per day, and the average yield, taking the bed as a whole,
