Extraordinary as this story sounds, it did not seem so to me when I heard it, for I had already met with many anecdotes of a similar nature in various parts of the country, some of them vastly more interesting than the one I have just narrated; only I did not get them at first hand, and am consequently not able to vouch for their accuracy; but in this case it seemed to me that there was really no room for doubt. All that I had previously heard had compelled me to believe that the puma really does possess a unique instinct of friendliness for man, the origin of which, like that of many other well-known instincts of animals, must remain a mystery. The fact that the puma never makes an unprovoked attack on a human being, or eats human flesh, and that it refuses, except in some very rare cases, even to defend itself, does not seem really less wonderful in an animal of its bold and sanguinary temper thau that it should follow the traveller in the wilderness, or come near him when he lies sleeping or disabled, and even occasionally defend him from its enemy the jaguar. We know that certain sounds, colours, or smells, which are not particularly noticed by most animals, produce an extraordinary effect on some species; and it is possible to believe, I think, that the human form or countenance, or the odour of the human body, may also have the effect on the puma of suspending its predatory instincts and inspiring it with a gentleness towards man, which we are only accustomed to see in our domesticated carnivores or in feral animals towards those of their own species. Wolves, when pressed with hunger, will sometimes devour a fellow wolf; as a rule, however, rapacious animals will starve to death rather than prey on one of their own kind, nor is it a common thing for them to attack other species possessing instincts similar to their own. The puma, we have seen, violently attacks other large carnivores, not to feed on them, but merely to satisfy its animosity; and, while respecting man, it is, within the tropics, a great hunter and eater of monkeys, which of all animals most resemble men. We can only conclude with Humboldt that there is something mysterious in the hatreds and affections of animals. The view here taken of the puma's character imparts, I think, a fresh interest to some things concerning the species, which have appeared in historical and other works, and which I propose to discuss briefly in this place.
