Fish inhabiting shallow coastal waters in all accessible parts of the world are at this moment in the process of being exterminated, through the mass invasion of these waters by spear-fishermen. On the Mediterranean shores of France and Spain, and all round the coastline of Italy the process is almost complete, so far as several species of fish are concerned, and we learn from the magazines of spear-fishing enthusiasts, of new centres of their sport being continually established on the more remote coasts of the Adriatic, of Greece and of North Africa.
