necessary that communicaticns facilities be adequately provided in order to 

 be able to find out vriiat sort of luck each boat is having and to coordinate 

 future operationSo

Skipjack fishing bases are selected on the basis of the above require- 

 mentSo

The subject of fishing grounds and seasons has been pretty well 

 exharsted in the section dealing with the distribution of the skipjack, 

 but it should be noted in addition that they are not the same from year to 

 year because of variations m the movements of the schools and in the
