The Salmon be 
the others. This difference in 
the number of lines during 
the different months, however, 
is hardly worth considering 
when it comes to longer 
periods. No mistake need, 
therefore, be made in dis- 
tinguishing between a grilse and 
a salmon, for one has only to 
count the number of lines on 
the scales by the aid of a 
small magnifying glass. If the 
number is less than fifty-eight 
it is a grilse. The only other

of the same age. Very 
few of the latter, however, 
are to be met with during 
November ; besides, a spring 
fish would be readily known 
without reference to its 
scales. 
As a rule, the greatest 
number of rings a grilse 
has is fifty-nine or sixty ; 
although, of course, there 
may be a few exceptions, 
in the case, for example, 
of a part that did not be- 
come a smolt until it was 
three years old, or one that 

became a smolt at the
