To those who do not understand the philosophy of the interest in breeding to highly specialized types the arguments for standards that are adjusted to common results and are easy to attain appear to be unanswerable. Upon the fancier who does understand this philosophy they make no impression at all. The breeding and exhibiting of fancy stock of any kind is primarily a game. The rules of the game are in a measure arbitrary, like the rules in baseball or football or any other game. At the same time they must be framed in the interests of the development of the game as a sport and also as a spectacle. They must be reasonable and must be suited to players of all degrees of skill. Standards and rules for judging fancy stock develop just as the rules of athletic games develop. A generation ago such games as baseball and football were comparatively simple games in which boys and men might take very creditable parts without devoting a great deal of attention to practice. These games still afford recreation to many who use them for that purpose only, but they have also been developed so that players of exceptional skill play competition games for the interest of a public which studies the fine points of these games and compares the abilities of the players. People who take an interest in and patronize professional or high-class amateur ball games do so because in them skillful and well-trained players do difficult things. It is the same in the breeding of fancy live stock to a high standard of excellence. When a breed or a variety is first made, the interest of the breeders centers in a few characters, precisely as the interest of a novice in any line centers in a few prominent features. As breeders grow in experience and in skill, and as the characters to which they first give special attention become fixed, they demand better quality in these and also turn their attention to the development of other characters. The more difficult a combination of characters is to produce, the greater interest the fancier takes in trying to produce it. When a standard calls for a high degree of excellence in many characters, the proportion of specimens of high excellence, as measured by that standard, will almost always be small. It is because this is the case that the rare specimens are considered so valuable.
