from one to two pounds; the shape is 
elongated and spindle-like ; the colors 
brilliant and beautiful. It usually spawns 
during the months of May and June, and 
it is when approaching the shores in vast 
shoals for this purpose, that they are 
principally taken. The most common 
mode in which the fishing is carried on 
in England, is by means of long drift- 
nets, which often extend for nearly a mile 
in length, descending into the water to a 
depth of about twenty feet. These nets 
are let down into the water at nightfall, 
and left in position all night, suspended

one extremity by a large buoy, and at the other attached to the fishing-boat. The meshes of 
the net are just large enough to allow the fish to pass through at the pectoral fins, so that when
