From the marking we are sure that the fish in the above Table were 

 smolts in the spring of 1905, and that they returned to the river as 

 grilse in the summer of 1906, weighing from lbs. in June to 9 lbs. 

 and more in August. From the scales we learn that all the specimens 

 were a little over two years old in the spring of 1905, when they were 

 migrating as smolts ; that all had spent one summer and one winter in 

 the sea ; and before returning had commenced the feeding of the second 

 summer, which is represented by six lines in the June capture and by 

 nineteen rather large lines in one of the August captures. 



The number of lines fairly corresponds to those on the scales of grilse 

 during the same months in 1903 and 1904,* if allowance be made for 

 the heavier weights and larger number of specimens examined in these 

 years. 



(2) Small Spring Salmon. (Plate III.) 



In reference to these salmon, perhaps it will be better to quote what 

 I have previously written regarding them when describing their 

 characteristics and scales : — 



" These small fish arrive in winter and spring, and the opinion 

 '•'is prevalent that they went down as late smolts, and were not 

 " ready to return with the grilse of the previous summer. They 

 "weigh less than many of the August grilse; but, unlike them, 

 " are not going to spawn until the following winter. Their parr 

 "lines are generally well defined, and point to a more abrupt
