It clearly appears from this curve that there are two sizes met 

 with amongst the Spring Herrings, one size of about 250 mm. in 

 length, and another of about 300 mm. It appears, therefore, to be 

 extremely probable that the true Spring Herring comprises two classes, 

 of which the lesser fish is about 250 mm. in length. During the Winter, 

 it is true, small sized Herrings are caught on the West Coast, but 

 these, however, do not belong to the »Ocean Herring«, but to the 

 »Fjord Herring«. 



In the Summer of 1894, I endeavoured to form an idea of what 

 size of Herring appears in the West Coast Fjords during Summer-time. 

 I succeded in getting the fishermen to net the smallest herring »Mussen« 

 (young Herring), and the next size »Bladsilden« (Herring of the second 

 year). 



The >Mussen« which spawns in February and March and therefore 

 in July and August is 5 or 6 months old, proved to be between Go and 

 JO mm. in length. The »Bladsilden«, which, therefore, must be presumed 

 to have been one and a half years old, was of a remarkably uniform 

 length of 120 mm. In one haul, twenty herrings were of the following 

 lengths, 120, 118, 122, 124, 126, 120, 114, 122, 120, 124, 126, 122, T30, 

 124, 128, 125, 126, 1 25, 120, 122 millimètres. Other sizes were not 

 meet with in the same haul. In other hauls such even figures were, 

 however, not found, so I am of the opinion that the size may be
