No sire has the same rank in all classes. Several have the same 

 rank in three classes. The smallest total of the rankings in the six 

 classes indicates the sire having the best general rank. 



This method of comparing the merit of several sires for their 

 ability to transmit milk and butterfat producing capacity to their 

 daughters is not without its faults, rrobably the most serious 

 fault is in allowing average production of milk and of butterfat to 

 have equal weight with the average increase of milk and butterfat 

 yield and the percentage of daughters that were better than their 

 dams. These last two qualifications would appear to measure fairly 

 the influence of the sire; but the first qualification, the average yield 

 of daughters, may be due to a very great extent to the influence of 

 the dams. 



An illustration of the influence that the high average production 

 may have in the final rankings is shown in sires Q, T, M, O, and P, 

 whose final relative rankings are near together. The average pro- 

 ductions of milk and butterfat of the daughters of these sires are 

 given in Table 6.
