THOMPSON YATES LABORATORIES REPORT 
condition of the oyster beds and layings, to re-assure the public, and to elevate the oyster 
industry to the important position which it should occupy. 
(b) Oysters imported from abroad (Holland, France, or America) should be consigned to 
a member of the ' Oyster Association,' who should be compelled by the regulations to have his 
foreign oysters as carefully inspected and certificated as those from his home layings. A large 
proportion of the imported oysters are, however, deposited in our waters for such a period 
before going to market that the fact of their having originally come from abroad may be 
ignored. If this period of quarantine were imposed upon all foreign oysters a great part of the 
difficulty as to inspection and certification would be removed. 
(c) The grounds from which mussels, cockles, and periwinkles are gathered should be 
periodically examined by scientific inspectors in the same manner as the oyster beds. The 
duty of providing for this inspection might well, we should suggest, be assumed by the various 
Sea Fisheries Committees round the coast. 
The samples examined are indicated in the following table : —
