But the case would be quite different if the winning sire and dam came from the same old established herd in which the animals had been bred for generations on similar lines. It is this concentration of certain qualities in generation after generation which renders the pedigree animal so intensely prepotent, particularly when mated with animals of an ordinary character or not possessing concentrated breeding. Indeed, it may be safely assumed that the power of a parent to impress its own individuality and qualities on its produce, depends to a very large extent, if not entirely, on the comparative hereditary extent of those qualities in comparison with the other qualities possessed by itself, or by the animal with which it may have been mated. In other words, it is contended that the sire or the dam has not the power to impress certain of its characteristics on its young, merely because of its sex, but that this power depends on the proportion in the sire or dam of the blood of progenitors who possessed in a marked degree certain qualities. It is with the breeding of animals as with the manufacture of a compound article. The character and quality of that compound will vary according to the proportion of the various ingredients used in its manufacture. It is to this law or fact that the marked impressiveness of certain strains of blood is attributable. Again, the marked and long continued success of the blood of the animals bred by a few of our most successful breeders of live stock is in the main due to the fact that the owners set up a standard and persistently selected and bred together only animals possessing to a greater or lesser extent the particular qualities which together comprised that standard. There is not the slightest doubt that in carrying out their system they were often compelled to mate animals related in blood the one to the other, but in this there is little risk providing that all those animals which show the slightest symptom of delicacy of constitution are persistently draughted out. It will be inferred from the above remarks that we hold to the belief that the breeding of the boar should receive attention as well as the following points in its form and character.
