Not only have these first generation heifers proved to be very 

 much superior to their dams in production, and thus clearly 

 demonstrated the value of a purebred dairy sire as an investment 

 for a common or scrub herd as well as for a high grade or pure- 

 bred herd, but a study of the illustrations also brings out the 

 great improvement in constitution, capacity, mammary develop- 

 ment, straightness of top line, quality and type. This improve- 

 ment is more marked in the second generation grades.
