 as soon as they are taken out of the water on a frosty 

 day. 



Hitherto we have dealt with but one class of oyster,

 we live to find out that in some parts of the world, such

 they will buy young oysters of English fishermen to daiau 

 in the grounds at Petten. In recent years the Australian 

 beds have proved so fruitful that an attempt has been
