OYSTEE BEDS OF JAMES KIVEE, VIRGINIA. 



47 



There is an abundant supply of shells on the dense area, a quantity 

 of doubtful sufficiency on the bottoms bearing scattering and very 

 scattering growths, and a deficiency on the depleted bottom.

MARSHY ISLAND ROCK. 



This lies between Mulberry Swash Rock and the inshore boundary 

 of the public ground, principally in the " addition" which was made 

 a part of the ground subsequent to the Baylor survey. The name 

 here employed is coined for the purpose of this report, as the name by 

 which this area of oyster bottom is known to the oystermen, if it has a 

 distinctive name, was not ascertained by the survey. The outer or 

 offshore boundary of the bed is defined more or less sharply by a 

 channel, carrying a maximum of from 21 to 27 feet of water, between 

 this and Mulberry Swash Rock. 



The condition and extent of this bed about the middle of August, 

 1909, was as follows:
