A description of each kind of vessel or boat, with diagrams illustrat- 
ing peculiarities of rigging or outfit, positions of ice-houses, baits, bins, 
wells, “‘slaughter-houses,” &c. The different kinds of vessels may be 
illustrated by engravings.

B, should be used in every fishing port, and should be thoroughly 
worked out. These require— 
1. Name of vessel.
