Nature has bestowed in the distribution of her various gifts, some characterestic badge to every animal, by which they know and are known to each other; and by which they are conversible with, or envious to one another. Sociability, or the love of herding, is not so peculiar to man, as man would boast. Lyons, horses, dogs, Cats, and the other species are as fond of forming colonies as we are. And yet in contradistinction to this principle, we see the Lion chase the _Jack-all_ for his caterer. The _Jack-all_, says _Pliny_, is endowed with the most excellent nose to investigate the paths of those weak, or timorous beasts, which are the Lion’s prey. This scent renders him the more useful to his friend the _Lyon_, whom he _leads by the nose_ to a herd of deer or oxen. The Lyon, wanting this fine scent, and convinced of his deficience, takes into his familiarity, and confidence, this weak animal, who makes use of the other’s strength, and from his own inability in personal prowess, compensates the loss by the admirable organization of his odorific nerves. Thus, in like manner, the Pilot-fish conveys the Shark to his prey: And I have read in some learned antiquary of a bird, called the _Tooth-pick_, which lives on the leavings of the _Crocodile_, who having filled his belly with what fish he can pick up in the _Nile_, lies on his back, on the banks of that river, and basks himself with delight, while this bird, guided by instinct, and no way afraid of his terrors, perches on his teeth, and from the gleanings feeds himself to satiety. We ought not in this detail omit to take notice of the _Fly-eater_, who puts his tongue out, till several thousand flies, have in swarms covered it, and when he perceives it to be pretty well stocked, all on a sudden introduces the cargo, where it is fairly entered; and this trick he plays for several hours, till the custom-house can hold no more. CHAP. III. _Of the more docile, and sagacious animals, such as Dogs, Horses, Elephants_, &c. There are few people but have either seen or heard of the _learned Dog, Le Chien Scavant_, and yet his uncommon knowledge, except we should now record it, will appear incredible to posterity. He could read, write, and figure, play cards, spell any person’s names, with many other parts in useful knowledge; and, as _Hudibras_ says, _Greek was to him no more difficile Than to a blackbird ’tis to whistle._
