The outstanding feature of this table is noticeable on in- 

 spection. The number of individuals repeated on the dam's 

 side of the pedigree is only a fraction of those repeated on the 

 sire's side of the pedigree. Since the popularity of an animal 

 is based on what is conceived to be his worth, it follows from 

 the above that the animals considered to be worth most are in- 

 cluded in the sire's side of the pedigree more often than they 

 are included in the dam's side of the pedigree. Such a selec- 

 tion would seem to mean that the sires are more carefully 

 chosen than the dams to which they are bred. This would 

 probably follow from the obvious difference in the reproduc- 

 tive capacities of a bull and a cow allowing as it does more 

 freedom of choice for the bull than for the cow.
