FERAL HORSES. 177

 cannot act in a similar manner, or the stallions 

 effect more than keeping some of their immediate

 guar and the puma only are dangerous to horses ; 

 both being tree-climbing carnivora, they seldom 

 roam far from the woods or venture on the plains, 

 where the thunder of horses* hoofs is sufficiently
