It will be seen that the great preponderance of oyster production 

 is on the dense areas, which exceed the bottoms of other character 

 not only in their average productiveness but in their total area. The 

 bottoms with a scattering growth, which in extent exceed the next 

 lower grade by about 12 per cent, excel them in their total content 

 by about 70 per cent, and are considerably more important in total 

 production than the combined areas of very scattering oysters and 

 depletion. Summarizing, the dense areas bear 78 per cent of the 

 total content of the rocks, the scattering areas about 12 per cent, the 

 very scattering about 7 per cent, and the depleted bottom about 3 

 per cent. Basing the computation on the basis previously defined 

 and the data presented in the preceding two tables, we find the esti- 

 mated maximum available product of the several rocks and their 

 subdivisions to be as follows:
