 cludes the Scad, C. trachurus, fifteen to 

 twenty inches long; caught in great num- 

 bers on the coast of Ireland, and com- 

 mon on the British coast; also in the

Genus SCOMBER: Scomber.— This

 it is when approaching the shores in vast 

 shoals for this purpose, that they are 

 principally taken. The most common 

 mode in whicli 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 

 to a stout rope, which is supported at 

 one extremity by a largo 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
