It has been contended that our various types had a common origin in the wild hog, and that the difference in form, colour, and character amongst the local breeds is due, in the main, to the requirements, imaginary or real, of the interested residents in the particular districts. On the other hand, it is asserted with equal confidence, and probably with the same amount of actual proof, that it would be impossible so to improve the wild hog by selection as to render it the equal of the domesticated hog. There must, therefore, have been an infusion of blood of a cultivated breed of pigs to acquire even that amount of success which was noticeable in the improved pig of a century, or less, ago. Unfortunately, for this argument, it has not been possible to obtain any information of value as to the alleged source of origin of this cultivated breed of pigs. Again, those pigs which possess in a marked degree early maturity, fine quality of flesh, and those other characteristics of the improved pig, are so various in colour, that one cultivated breed only could not have been utilised in the general improvement. All the ancient writers on pigs appear to have experienced the same difficulty when endeavouring to discover the sources of origin of the material which might have been used in the production of the pig which in their time was looked upon as the domesticated and improved pig of the period. This difficulty extends even to the present day. So far as is known there exists no actual proof that the domesticated hog has been evolved in any particular way other than by continued selection of those animals for breeding purposes which possessed in the greatest degree those particular qualities held in the highest estimation at the time.
