for the 1914 aud 1915 curves, a fact which would make the corresponding modal length 

 less than that shown. 



The numbers of winter rings have been counted for the scales of the fish of catches 

 3, 6 and 7, and the results are shown in table 12. The table shows that these catches, 

 which had a mode at 67 cm., were composed predominately of 6-year-old fish. Thi= 

 being the case, the mode at 72 cm. of the curve for catches 41 to 62 shown in fig. 1, 

 probably corresponds to the 7-year-old fish or the fish of the 1909 year class, the same 

 which gave rise to the modes in the 1914 and 191.5 curves. 



VII. — SUMMARY. 



1. It has been found that young pollock showing in their scales no winter rings and 

 therefore probably in their first year's growth occur in shallow tidal water on the 

 western coast of the Bay of Funday. 



2. Data as to the rate of growth during the first two years are given. 



3. Evidence is given for believing that the 1909 class has been the most abundant 

 during the three years 1914, 1915, and 1916.
