 German trawlers; but in 1916 the Scottish trawlers considerably 

 increased their Iceland catch. From Faeroe the catch has suffered 

 remarkably little, and its relative importance has steadily and 

 greatly increased as follows : —

 the relative shares contributed by the various regions to the total 

 trawled catch, in the four successive years 1913-16.

In our next Table (M), we show the average catch per voyage (in 

 cwts.) of the whole Aberdeen trawling fleet for the years 1905-1916.
