sire in respect to their butter-fat transmitting qualities. This 

 conclusion need not necessarily hold for another group of sires, 

 for if one thing is clearly brought out by this progeny study on 

 Jersey sires it is the fact that the inherited complex which a 

 bull is able to give to his daughters is an individual proposi- 

 tion and requires individual study rather than any mass study. 

 Considering the number of daughters two bulls stand forth 

 among the rest as of superior merit, Hood Farm Torono and 

 Spermfield Owl. The pedigree of Hood Farm Torono has 

 already been given. The Pedigree of Spermfield Owl is pre- 

 sented below.

Spermfield Owl's pedigree shows that he is by a bull and 

 from a cow which were imported to this country. The benefit 

 to the dairy interests of the Jersey breed, as shown by the per- 

 formance of this bull in his progeny test, certainly more than 

 justifies the importation of these two animals.
