bining the information in these tables it is possible to obtain 

 a table showing the sires which increased the milk production 

 and butter-fat percentage of their daughters over that of their 

 dams. This has been done. The results are shown in table 8.

Twenty-eight Jersey sires qualify as bulls which have ma- 

 terially advanced the Jersey breed. These bulls are arranged 

 in order of the net change of the butter-fat between the bull's 

 daughter and the dam to which the bull is bred. The leader 

 of the sires is Signal's Successor who increased the milk pro- 

 duction of his daughters 2899.5 pounds, their butter-fat per- 

 centage 0.202 per cent and made a net change in the butter- 

 fat of 177.72 pounds. Considering the number of daughter- 

 dam pairs which each bull has, the other bulls of outstanding 

 worth are Golden Glow's Chief, Tormentor's Landseer Signal, 

 Golden Ferris Son, Spermfield Owl, Rioter's Jersey Lad, Pogis
