32 HISTORY OF THE OYSTER. 



to Laxey ; another is found in Ramsey Bay, also 

 famous for scollops. A few oysters are also found off 

 Ballaugh. 



Most of these beds have nullipore on them, which 

 is very injurious. 



The chief beds of North Wales are those of Bardsey, 

 Forth Dyllaen, Rhoscolyn, the Menai Straits, and 

 Beaumaris ; on the latter of which great numbers 

 of oysters, brought from Ireland, are laid down, 

 to be ready for the Liverpool market. Caernarvon 

 Bay contains numerous beds, as those of Llandwyn. 

 There are also beds in the Tudwal roads off Pwyl- 

 helli : many of them owe their preservation to the 

 nature of the coast, the fishing not being allowed in 

 the summer, and in winter the westerly gales pre- 

 vailing, and no safe harbour to run to. Except in 

 September, there is not much fishing going on. 



In South Wales there are many beds. Milford 

 furnishes a good supply. 



It is almost impossible to arrive at an exact estimate 

 of the annual supply of oysters; but probably the 

 following is an approximation *, as far as it goes : 



London 130,000 bushels. Mr. "Wickenden. 



Channel Islands . . 8,000,000 tubs. Dr. Knap. 



Newhaven 1,013,760 oysters. D. Moffat. 



Preston Pans 1,013,760 oysters. D. Moffat. 



Shannon beds yield a revenue of 1400. per annum.
