 the different months, however,

 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 

 fish that can approach this

 few of the latter, however, 

 are to be met with during 

 November; besides, a spring

As a rule, the greatest

 of a parr that did not be-

 three years old, or one that 

 became a smolt at the 

 age of one year, as some
