report. On comparing Dr. Iljort's and my results in the case of this Pample, it was 

 found that we agree as regards the young fish, but not in respect of the older one.s, 

 Dr. Iljort having on the whole counted fewer rings on the scales of old fish than I. 



T.xBLK 11. — Sample of large and old herring from Nova Scotia, August, 1914, present- 

 ing difficulties as regards age determination. The table shows the results 

 arrived at by Dr. Hjort after his preliminary examination, compared with the 

 results of Lea's two analvses 



These different results may be compared, in table 11, which further shows that my 

 first estimates, when compared with an analysis subsequently made, likewise reveal 

 some discrepancy in the case of the older fish. The scale preparation for this sample 

 not being perfect, and the difficulty in the case of older fish being, as already men- 

 tioned, considerable, all that can be said as to this sample is that there were a large 

 number of old fish and that age-group 7 (year-class 1908) is well represented as com- 

 pared with the neighbouring groups. 



Table 12.— Age distribution in a sample of immature herring from Halifax, X.S., 

 and a sample of mature and ripe herring from Lockeport, N.S. Autumn, 1914. 



Besides this sample we have also one from Lockeport, Xova Scotia, taken in Nov- 

 ember, 1914, consisting of mature fish, and another from Halifax, October 1914, with 

 immature fish. Table 12 shows the age distribution in these samples. The sample of 

 mature herring shows an unmistakable likeness to those from Ardoise, its best year- 

 classes being 1911, 1910, and 1908. In the sample of immature fish, the 1911 year- 

 class is very numerously represented. 



The two samples of small herring from the Bay of Fundy and Gloucester, Mass., 

 present no features of interest in this connection; they contain quite young herrings 

 with one to three summer belts on their scales. 



Taking a general survey of all samples from the Atlantic coast, we find, it is 

 true, a somewhat complicated picture with much varied detail, nevertheless, one 

 cannot fail to see that these samples reveal certain definite featurei= upon which to 

 base a further grouping of tlie material. Rave for the samples from Grand Narrows,
