Report of the Board of Shell Fish Commissioners 49 



k 



the undersized oysters found on the ground during the survey 

 will have grown to marketable size and that one-third of the 

 marketable oysters will remain. Many of the young oysters 

 on the grounds at the time of the survey will die during the 

 year following, and but few of them will have attained a 

 length of four inches at the end of a year. 



OYSTERS OF UNIFORM SIZE. 



By another method for ascertaining the number of oysters 

 per bushel, a large quantity of oysters of all sizes was carefully 

 separated into groups of oysters of uniform size, and one- 

 fourth bushel of each group was counted. The result of these 

 measurements and counts is given, since it will prove interest- 

 ing to some readers. 



Supposing that, in making a day's catch on the grounds, an 

 equal volume of oysters of each size is taken, each legal oyster- 

 bushel would consist of 406 oysters. ,
