opportunities at other times of the year should be made use of to 

 observe the remaining features of the water-circulation. If this work- 

 were continued for a few consecutive years there can be little doubt 

 that a method would be found of ascertaining, and even forecasting 

 with considerable accuracy, the distribution of food-fishes at different 

 seasons and in different years. The value of the work would of 

 course be greatly increased by cooperation in the investigations 

 carried on by Sweden and other countries ; indeed a complete solution 

 of the problems affecting any one of the parties concerned can scarcely 

 be looked for without some such mutual help.
