the majority of the fish belonged to the year classes 1907—1905, some however, being 
still older, from 1905 and 1904. In 1911, the 1908 year class is predominant, as is also 
the case in 1912. We thus find here, as in the case of the Shetland samples, a great differ-

1912, the herring shoals were mainly composed of great quantities of young fish of recent 
year classes, especially those of 1908 and 1909. Other samples from northern waters (Ty- 
nemouth) exhibit a similar numerical predominance of the 1909 year class. 
If we now endeavour to make a comparison with the results of the fishery statistics,
