ferent from that in England, and not so expensive. At Ar- 

 cachon tiles are used, to which the spat attaches itself when 

 floating about the bay. Walls about eighteen inches high 

 are made of the tiles on the mud -banks, which retain the 

 water when the banks are dry at low tide. In these ponds 

 the young oysters are kept after they are taken off the tiles. 



At Auray the collectors of spat used are tiles, wooden 

 boards nailed together, and slates. The wood seems to an- 

 swer admirably well. 



At L'Orient the apparatus of cultivation consists of what 

 are called Michel's Patent Concrete Pans. These are about 

 two and a half by one and a half feet, and eight inches 

 deep, retaining the water when the tide is out. The young 

 oysters remain in these pans, and the growth made in one 

 year is very remarkable. The temperature of the water at 

 L'Orient was sixty-eight degrees.
