AGE OF THE DOMESTIC ANIMALS. 



In the first four years the teetli are the most valuable 

 indications of age, from four to ten years the horns furnish the 

 more accurate signs, and after ten years a careful comparison of 

 both is required to determine approximately the number of years 

 which have passed.
