should be observed. _Shipment of Opened Oysters._--Opened oysters are shipped extensively to all parts of the country. After removal from the shell the oysters are washed to remove the natural water, since this becomes ropy during shipment. They are then packed in wooden tubs of various sizes, a piece of ice added, covered, and delivered to the fast express or freight service. In this way the oysters may be kept free of dangerous deterioration for several days. In such cases care must be exercised to keep the temperature low and to secure a sanitary environment. Thus protected the oysters should arrive at their destination without any further change than the necessary loss of flavor caused by the conditions of preparation and transportation. _Proportion of Shell and Oysters._--The following illustration (Report of the U. S. Commissioner of Fish and Fisheries for 1888, page 784) shows the relative proportion of the flesh, liquid, and refuse for two or three varieties of oysters: Name: Oysters (“East Rivers”).
