CHAPTER V 

 THE PROFIT 



I. The revenue of drift-nets, trawls, and lines in the North Sea, the 

 Channel, the Atlantic, and the Mediterranean. II. The revenue 

 of boats ; sailing boats and steamers ; average productivity. 



III. The earnings of sailing vessels and steamers ; economic 

 sketch of the Boulogne district; the size-limit of steamers. 



IV. The earnings of fishermen in France and Great Britain 

 The yield per square mile of the principal fishing-grounds. 



HARBOURS, boats, gear, and fishermen, these are the four

 ments, and how they are used. We must now consider 

 the pecuniary value of their work. I shall devote two 

 chapters to this subject, dealing with it from the statistical 

 and the economical point of view.

First of all let us take the yield of the various kinds of
