station, went to Scotland. Once again the 

 situation was confirmed in 1937 (Fig. 7) 

 (the southern station was not in use) ; no 

 fish went to Eussia but five went from the 

 middle station to Great Britain. In this 

 year (1937) Professor Dahl started another 

 station, a long distance from his earlier sta- 

 tions, on the island of Soroy, West Finmark, 

 and not a great distance from the extreme 

 north of Norway. From this station the re- 

 sults are rather different from those obtained 

 further south, A certain number of re- 

 captures were made within a moderate dis- 

 tance (38 within about 130 miles) and many 

 of these were in the local rivers. Beyond 



this distance none were captured to the 

 south but in the opposite direction no less 

 than about 90 were taken at a greater dis- 

 tance. These latter were spread along the 

 north coast of Norway, of Finland and Rus- 

 sia to the rivers of the "White Sea and be- 

 yond even that to the river Petchora, which 

 is reputed to be the eastern limit of Salmo 

 solar. 



Such is the evidence obtained in Scotland 

 and in Norway of the main migrations of 

 the salmon returning from their feeding 

 grounds. The whole would be consistent 

 with a general move in from the westward 

 towards the coast, and seems to imply a defi-
