 tile Atlantic States, and we do not recollect a

 recorded of the puma making an unprovoked attack 

 on any human being. In South America also the 

 traveller in the wilderness is sometimes followed by 

 a puma ; but he would certainly be very much

I have spoken of the comparative ease with 

 which the puma overcomes even large animals, 

 comparing it in this respect with the peregrine

 attacks are successfully resisted by the ass, which 

 does not, hke the horse, lose his presence of mind, 

 but when assaulted thrusts his head well down be-

 in the neighbourhood of El Carmen, while riding 

 near the river had his curiosity aroused by the
