It will be noticed that all the single samples examined were found to contain a 

 large number of 10 year old fish, i. e. , spawned in 1904. The percentage of this 

 age group varies, in the case of the fish from Fuglo, from 44.0 to 50 "/o, for those 

 from Brandesund between 41.6 and 48.4 "/o- The average percentage of the 1904 

 year class was, for Fugk 47.8% and for Brandesund 44.9%. 



It will further be seen that the 1905 year class is in all the single samples the 

 next in numerical value. 



The remaining year classes occur, as will be seen, in such inconsiderable numbers, 

 that no close agreement can be expected to appear between samples consisting of 

 only about a hundred fish. 



In the following table, the specimens examined are arranged in order of size, in 

 whole cm. groups. It wijl be seen that the 32 cm. group is in all the individual

samples that which contains the highest percentage of the total number, and that 

 the great majority of the fish in all the different samples fall to the 31, 32, and 

 33 cm. groups (80 to 90 %). 



The average size varies between 31.2 and 31.8 cm. 



From these investigations it is thus evident that the single samples agree in all 

 essentials to approximately the same extent as the herring samples hitherto investi- 

 gated in Norway.
