The new international encyclopaedia . fattening oystersartificially, by using fertilizers to stimulate theproduction of oyster food in ponds.

Plump-ing them by placing in fresh or nearly freshwater is a bloating and not a fattening treatment,and is less resorted to than formerly. Oystersshould not be planted or bedded in the vicinitj-of sewage contamination, as they may therebybecome sources of disease infection, but there isno danger to be anticipated from the consumptionof oysters from beds remote from sources of con-tamination. Green oysters are sometimes placedon the market. There are three types of green-ness, two of which are perfectlj harmless. Thethird type is evidently a pathogenic condition,correlated with the presence of copper; but, whilethe aflected oysters are poor in quality, it is notdemonstrated that they are OY8TER 1.

In England oyster culture is practically alongthe same lines as in the United States. Shellsare used to collect the spat, and seed-oysters areplanted in favorable places, notably on the bot-toms controlled by the Whitstable Company, acooperative corporation. On tlie Continent themethods are more elaborate, the low price oflabor and the high price of oysters, as well asthe restriction of the area upon which they canbe grown, tending to encourage an intensive sys-tem of culture.
