ALASKA. 151 



The females, adults, will correspond with the three-year-old 

 males in the above table, the younger cows weighing frequently 

 only 75 pounds, and many of the older ones going as high as 

 120, but an average of 80 to 85 pounds is the rule. 



The five and six year old males, when they lirst make their 

 appearance in May and June, are very much heavier than at 

 the time I weighed them in July ; they are then, perhaps, when 

 fat and fresh, fully one-third heavier than the exhibit on the 

 table, but the cows and other classes do not sustain protracted 

 fasts, and do not vary much through the season.
