of smolts taken in 1962 are given in table 12. 

 The high condition factor in Ruth Lake smolts 

 was expected because smolts from there have 

 always appeared more robust than have their 

 counterparts from Little Kitoi Lake (fig. 12). 

 The general increase in condition factor was 

 also apparent in each lake as the migration 

 progressed from May 28 to June 25, 1962
