to be of some use to the practical fisherman. To those whose duty it is 
to study the fisheries from the point of view of legislative or administra- 
tive control, it is of course of the very greatest importance. 
As was explained at the beginning of this address, I have attempted 
to lay before you some account of one single branch of fishery research, 
and as I have proceeded you will no doubt have felt that a subject which 
at first sight seemed fairly straightforward and simple developed quite 
unexpected complexity, and yielded in the end quite unexpected results. 
This is indeed only the common experience of those who break new ground 
or explore new territories in any branch of knowledge whatever, but in 
the case of marine research the difficulties are perhaps exceptionally 
great and the calls on the patience and perseverance of the investigator 
are almost unlimited. But those who have been most intimately asso- 
ciated with this research and have followed it in greatest detail are the 
most convinced of its promise of fruitful result. We must look to the 
growing intelligence of the larger public, grown wiser, may we hope, in 
the stern school of war, for that appreciation which will enable it to be 
continued with the means and resources which its difficulties demand.
