184 APPENDIX TO REPORT ON OYSTER CULTURE 



the young oysters will thus be protected from the ravages of parasites, 

 and the inclemency of the weather. 



The tables with fascines have a large quantity of spat on them, but on 

 the 2,000 fascines there are not so many, owing to the great heat. The 

 drainage pipes that form the boundary of L'Ahilon have all spat on them. 



Loss owing to the great heat. 

 This loss will be recovered ; the spatting of part of the oysters, at a 

 time when the weather was warm and fine, has tended to cover the old 

 oyster shells, the cultch, and the large oysters, in an extraordinary man- 

 ner. The rubble of L'Ahilon has very little spat except on the lower 

 part of the blocks. 



Tempest of the 20th and 21st September. 



The tempest of the 20th and 21st September has cleaned the parks, 

 washed away the mud and the seaweeds, but the parks of Ces and 

 L'Ahilon lost many oysters which were thrown upon the neighbouring 

 foreshores and into the channels, they will be found later on in the 

 public fishing. It is a description of forced sowing. 



Park du Ces. 

 The park of Ces is in a good state of natural reproduction, which is 

 shown most on the cockle shells ; we owe this result to the great care 

 which has been bestowed on it, in management, and in keeping it clean. 

 The spat on 5,000 tiles there is superb. This park will have to be ren- 

 dered " healthy," as it were, by means of channels cut with a fall, by 

 having it raked, and by having the weeds taken away. The park of Ces 

 has suffered by the great heat, and by the tempest of September, but it is a 

 very reproductive and precious bed. In 1870 it will be necessary to put 

 down 100 cubic yards of cockle shells, and 2,000 tiles. 



Crastorbe. 



A good park, well kept, sixty cubic yards of cockle shells were put 

 down ; the channels for the improvement of the park and to allow the 

 water to run in work well. Natural reproduction is good. The cultch 

 put down at a suitable time shows a good spat. Walking must be pre- 

 vented on this park as the soil is very soft ; people after ducks and courtines 

 must be prevented from going on to it; even supposing that each person 

 does not gather some oysters, the way in which they have to follow their 

 calling destroys the young oysters, not only on Crastorbe, but especially on 

 its borders, which are rich, and naturally derive benefit from the works and 

 the spat on the park. 



The watchfulness of the guards and of la Goalette la Loubine is very active 

 and efficacious, but very fatiguing. 



Claires de Crastorbe. 



The claires ordered to be undertaken by the Minister of the Marine 

 are in course of construction on the first hectare of the Sud and Crastorbe. 



A special report with plans will be furnished, but it is best to wait 

 until the works are completed, as there might have to be some modifi- 

 cation of the original plan, considering the clayey and soft nature of the 

 soil. 



The oysters will be well preserved there, in shelter from mud, and all 

 dead sea-weed. Two claires nearly finished answer already very well ; 

 the weeds and anything else that float towards the entrance of the 

 water into the claires are all removed with rakes. The parkers will find 

 here a subject for serious consideration.
