Fig. 2. Ossegor, near Bayonne. A natural tidal Lake fed and drained by a 
SHALLOW, SWIFT-RUNNING CREEK. 
The water is sufficiently deep to allow the cases to be rarely exposed. Oyster growth is extremely rapid; an 
instance of half an inch shell growth in a month is recorded. Cases are naturally covered with filamentous sea 
salad, ulva, which protects the oyster against light and heat, and gives attachment and shelter to the rapidly 
growing oyster food. (Page 375.) Park of MM. du Puy, St. Martin, and Daste.
