Perhaps the most special adaption which man has brought about in his domesticated animals is found in our pointers and setters. In these groups the dogs have been taught, in somewhat diverse ways, to indicate the presence of birds to the gunner. Although the modes of action of these two breeds are closely related, they are sufficiently distinct to meet certain differences of circumstances. The peculiarities of their actions, it should be noted, are altogether related to the qualities of our fowling-pieces. These have been in use, at least in the form where shot took the place of the single ball, for less than two centuries, and the peculiar training of our pointers and setters has been brought about in even less time. It seems likely, indeed, that it is the result of about a hundred and fifty years of teaching, combined with the selection which so effectively works upon all our domesticated creatures. It thus appears that this peculiar impress upon the habits of the hunting-dog is the result of somewhere near thirty generations of culture. [Illustration: Pointer Retrieving a Fallen Bird] Although, as has been often suggested, the pointing or setting habit probably rests upon an original custom of pausing for a moment before leaping upon their prey, which was possibly characteristic of the wild dog, it seems to me unlikely that this is the case, for we do not find this habit of creeping on the prey among our more primitive forms of dogs nor the wild allied species as a marked feature. All the canine animals trust rather to furious chase than to the cautious form of assault by stealthy approach and a final spring upon their prey, as is the habit with the cat tribe. Granting this somewhat doubtful claim that the induced habits of these dogs which have been specially adapted to the fowling-piece rest upon an original and native instinct, the amount of specialization which has been attained in about thirty generations of care remains a very surprising feature, and affords one of the most instructive lessons as to the possibilities of animal culture.
