tin Morgan, died from the effects of a kick at the age of 



years, and was, at the time he was hurt, in almost full 

 possession of his great strength. Upon the whole, I think 

 that twenty-one might be regarded as the horse's natural age. 

 Perhaps as great a per cent, of horses live beyond that age, 

 as of the human family live over "threescore and ten." 

 Zoologists give us the rule that the natural life of an animal 

 is five times the time it takes it to attain its full growth. Ac- 

 cording to this rule, the natural age of the horse would be 

 about twenty-five years.
