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§ 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,
