The onset of the jaguar is always made from behind, partaking of the stealthy, treacherous character of his tribe; if a herd of animals, or a party of men be passing, it is the last that is always the object of his attack. When he has made choice of his victim, he springs upon the neck, and placing one paw on the back of the head, while he seizes the muzzle with the other, twists the head round with a sudden jerk which dislocates the spine, and deprives it instantaneously of life; sometimes, especially when satiated with food, he is indolent and cowardly, skulking in the gloomiest depths of the forest, and scared by the most trifling causes, but when urged by the cravings of hunger, the largest quadrupeds, and man himself, are attacked with fury and success. Mr. Darwin has given an interesting account of the habits of the jaguar: the wooded banks of the great South American rivers appear to be their favorite haunt, but south of the Plata they frequent the reeds bordering lakes; wherever they are they seem to require water. They are particularly abundant on the isles of the Parana, their common prey being the carpincho, so that it is generally said, where carpinchos are plentiful, there is little fear of the jaguar; possibly, however, a jaguar which has tasted human flesh, may afterwards become dainty, and, like the lions of South Africa, and the tigers of India, acquire the dreadful character of man-eaters, from preferring that food to all others. It is not many years ago since a very large jaguar found his way into a church in Santa Fe; soon afterwards a very corpulent padre entering, was at once killed by him: his equally stout coadjutor, wondering what had detained the padre, went to look after him, and also fell a victim to the jaguar; a third priest, marvelling greatly at the unaccountable absence of the others, sought them, and the jaguar having by this time acquired a strong clerical taste, made at him also, but he, being fortunately of the slender order, dodged the animal from pillar to post, and happily made his escape; the beast was destroyed by being shot from a corner of the building, which was unroofed, and thus paid the penalty of his sacrilegious propensities. On the Parana they have killed many woodcutters, and have even entered vessels by night. One dark evening the mate of a vessel, hearing a heavy but peculiar footstep on deck, went up to see what it was, and was immediately met by a jaguar, who had come on board, seeking what he could devour: a severe struggle ensued, assistance arrived, and the brute was killed, but the man lost the use of the arm which had been ground between his teeth.
