Put about fifty Oysters in a colander and drain. Pour over them a pitcher of cold water, and then put them into a hot kettle. Let stand covered for a few minutes. Add one pint of water. Rub together a tablespoonful of butter and one of flour; add a little of the Soup to make a smooth paste. Put this with a quart of milk into the soup kettle with oysters, and stir till it begins to thicken. Add a teaspoonful of salt, and pepper to taste.
