Meanwhile, we must be content to use the available statistics for the nearest approxima- 

 tions, and for a comparison of the catches in the different countries. Committee A has also 

 endeavoured to utilise the data of the statistics in this way for some chosen years. The 

 constantly increasing importance of the cod in the more northern parts of the region under 

 observation, and the increasing catches of large cod in the winter months have been determined 

 from such a compilation of the statistics.
