than the Baltic Current. One of those years (1893), the salt layers ran 

 far up the Christiania Fjord, and both the prey and the Herring fol- 

 lowed the salt current, while, during 1894, the salter layers lay far out 

 in the Skagerak, and were met with in the Christiania Fjord only at a 

 great depth. Under these circumstances the fishing under the coast 

 was a failure, whilst great masses of fish were observed at a distance 

 of 16 to 20 miles to sea. 



It must be left to further systematic investigations to extend, confirm 

 or limit these experiences. 



Such investigations must, however, not be confined to local, partial 

 investigations near land. They must also be carried out with an ende- 

 avour to explore the open sea whence the fish come, so that both the 

 coastal waters, and all the layers which flow in towards the shores, be- 

 come known. When it is thoroughly known whence these layers come, 

 under what conditions they approach the land, and when at the same 

 time for several years, observations have been made of the migration 

 of the fish, will the (question that has been treated here be opened 

 to clear understanding.
