Report of the Board of Shell Fish Commissioners 189 



for fattening oysters to which they may transplant their stock 

 before placing it on the market. That there are such fattening 

 grounds here and there in the Bay and its tributaries is a well- 

 known fact, but their location can be determined by experience 

 alone. Rapid fattening depends upon the richness of the food 

 supply and the number of oysters on the bottom. The richness 

 of the food supply in any locality fluctuates from season to 

 season, but the density of oysters on the bottom can be regu- 

 lated by the planter.
