[The disposition to hunt by scent is not peculiar to the setter or pointer, but in fact is common to all animals; developing itself in different proportions according to their various physical constructions and modes of life. The method of finding and pointing at game, now peculiar to these dogs, and engendered in their progeny through successive generations, is not the result of any special instinct, that usually governs the actions of the brute creation--but rather the effect of individual education and force of habit upon their several ancestors. This habit of life, engrafted through progressive generations into these breeds, has become a second nature, and so entirely the property of the species, that all its members, with but little care on the part of man, will perform these same actions in the same way, and will ever continue to exhibit these propensities for hunting, provided opportunities be offered for indulging them. Nevertheless, as these peculiar predilections for "'setting or pointing'," as before said, are the effect of education and habit, the artificial impulse would very soon be entirely obliterated, if not encouraged in the young dogs of each generation. This circumstance alone, proves to us the importance of getting dogs from a well-known good strain, whose ancestors have been remarkable for their exploits in the field. This necessary precaution will insure a favourable issue to our troubles, and lessen materially our labours. In fact young puppies have been frequently known to exhibit this propensity the first time they have been taken to the field. Some of these dogs have come under the notice of the writer, who at a few months old exhibited all the peculiarities of their race; in fact were "self-broke." These dogs were the progeny of a well-known imported stock, in the possession of a gentleman who selected them in England. Although other dogs, and other animals even, have been with great difficulty and perseverance taught to find and point game, still these two breeds seem especially adapted by nature, both in their physical and intellectual construction, for the performance of this particular duty to man. The sense of smell is differently developed in different animals; the olfactory nerve of the dog is larger than any other in the cerebrum, which peculiarity will at once account for their wonderful powers of scent. 'Swine', also, have these nerves largely developed; and necessarily so, as both in a state of nature or half-civilization, the greater portion of their food is buried under the earth or mingled with the filth and mire of their sties, and would pass unheeded, if not for the acuteness of their nasal organs.
