The large and constant supply of excellent food obtained 

 from the seas all round the coast by moderate labour and 

 expense, and the employment afforded to a numerous and

 ground surface, the situation of banks and channels, with 

 the particular direction and force of tides and currents, render 

 the British fisheries also, in many points of view, a branch of 

 political economy of great national importance. 



It has long, however, been matter of general regret that 

 the subjects of this particular branch of natural history, so 

 valuable as articles of food and commerce, and so interesting 

 from their organization, and the peculiarities and beauty of 

 their varied forms and colours, should, with the exception of 

 those inhabiting the fresh water, and the marine species most 

 in request for the table, be almost wholly unknown. 



Bewick's work, illustrated with engravings on wood of
