slipper-limpet

We learned that the Minister once smoked a pipe of Irish tobacco, and said "Never Again"; that the slipper-limpet, formerly the terror of the oyster-beds had now by the ingenuity of his Department been transformed into a valuable source of poultry-food, and that the roundabout process by which the Germans in bygone days imported eel-fry from the Severn for their own rivers, and then exported the full-grown fish for the delectation of East-end dinner-tables, had been done away with.
