The leading imported bulls, together with their son's pro- 

 geny records, are :

Surprising as it seems three of the native sires have no 

 sons that had tested daughters from tested dams. Perhaps still 

 more surprising, in view of the fact that the native bulls' daugh- 

 ters were superior to the imported bulls' daughters when com- 

 pared with their dams, is the general inferiority of the native 

 bulls' sons to the imported bulls' sons. The best showing made 

 by the sons of one of these native bulls was that made by those 

 of Spermfield Owl. The best showing of an imported bulls' 

 sons was made by those of Royal Majesty. The facts in regard 

 to the merit of these groups of sires need to be tested further. 

 It is one of the purposes of the subsequent section to examine 

 all the bulls' pedigrees for their island and American ancestry 

 and not such a selected sample as the one chosen by Mr. Sibley. 



Jersey Sires Which Materially Advanced the Jersey 



Breed. 



The dairyman today looks at a cow from two points of 

 view, how much milk will this cow produce and what is the 

 butter-fat percentage in this milk. It appears beyond question 

 that the cow of superior merit is the animal which produces a 

 large amount of milk and whose milk has a high butter-fat test. 

 If this is so, it appears equally without question that the sire 

 of superior merit is the animal which raises the milk produc- 

 tion and butter-fat percentage of his daughters over that of 

 their dams. Table 4 gives the bulls which raised the milk pro- 

 duction of their daughters over that of their dams. Table 5 

 gives the similar data for the butter-fat percentage. By com-
