The task of writing a description of the various breeds of swine has been rendered less difficult by the formation during the past half-century of societies for the registration of the pedigrees of the pigs of the different breeds, and by the setting up of scales of those points which pigs for entry in the particular herd books should possess. The first of these societies was the National Pig Breeders Association, of which the present writer was the honorary secretary for two years. At the time of its formation the breeds of pigs most generally recognised were the Berkshire, the Large, Middle, and Small Whites or Yorkshires, and the Small Black breed. It was intended that the pedigrees of the pure bred pigs of each of these breeds should be recorded by the Association and published in one herd book. There is no doubt that this would have been an ideal plan, and would have resulted in a saving of much labour and expense, and decidedly more convenient for those connected with the export trade. For reasons into which it is not now necessary to enter, the breeders of Berkshires determined to have a separate herd book; therefore, they started a society which they named the British Berkshire Society, to distinguish it from the American Berkshire Record. Subsequently the Tamworth breed of pigs became recognised by the Royal Agricultural Society, and the breeders of the red pig joined the National Pig Breeders Association. Then the demand for Small White and Small Black pigs ceased, so that eventually the pedigrees of Large White, Middle White, and Tamworth pigs only were registered in the N.P.A. Herd Book. Subsequently the breeders of Tamworth pigs formed themselves into a society presumably for propaganda work, and to conserve the interests of breeders of Tamworth pigs. Of late years other breeds of pigs have been brought to public notice, and have had herd books, and societies specially devoted to their particular interests. The Large Black, Large White Ulster, the Lincolnshire Curly Coated pigs, the Gloucestershire Old Spots, and the Cumberland pigs have their pedigrees recorded. An attempt was made some years since to resuscitate the Oxfordshire Spotted pig, but it was not a continued success. It is quite possible that other local breeds of pigs may find sufficient admirers to form societies to bring before the public the many good qualities possessed by the pigs of these breeds, but apart from local interest it is at least doubtful if any permanent benefit will supervene from this multiplication of herd books--save that it may increase the interest in pig breeding, a result devoutly to be prayed for.
