than in others. The men who have been most successful as 

 breeders have always refrained from purchasing animals the 

 pedigrees of which showed undesirable ancestry. Auction 

 sales of live stock bring out various interesting features, 

 chief among which is the relatively higher price paid for 

 animals of recognized satisfactory pedigree. While it is true 

 that in the past many animals have sold at high prices, 

 largely on the basis of pedigree and without merit otherwise, 

 the fact remains that, as a general rule, a combination of 

 individual excellence and meritorious pedigree brings the 

 highest price. The man who combines the capable judge 

 and wise interpreter of pedigree is ciualified to select his 

 animals and improve his herd to the best advantage.
