INTRODUCTION.—PRESENT CONDITION OF THE OYSTER 
INDUSTRY UPON THE COAST OF FRANCE. 
The oyster industry, which was formerly carried to a high degree of 
perfection by the Romans, as shown by the results obtained at Lake 
Luerin by Sergius Orata, who, according to the testimony of his con- 
temporaries, would not have found any difficulty in causing oysters to 
thrive upon the roofs of buildings, and by the industry yet in full activ- 
ity at Lake Fusaro, has always been left in France entirely to the forces 
of nature. Asa result of this our numerous oyster banks, furnishing 
sufficient supplies for all demands when the imperfect means of com- 
munication hindered the shipment of this mollusk from point to point, 
have not been able to resist the abusive fishing to which they have been 
subjected since our railroads have afforded facilities whereby the oyster 
can be carried to all parts of the country, and thus to millions of new con-
