TRANSMISSION 



BREEDING RECORD OF THREE CLASSES OF STALLIONS : i , SIRES OF 



SIRES; 2, SIRES OF DAMS; 3, SIRES OF BOTH SIRES 



AND DAMS OF SPEED 



4. One outside circumstance helps to relieve the burden of 

 inferiority resting on Class 2. A stallion belonging to an un- 

 fashionable line would be used but little or not at all in the stud, 

 while a mare belonging to an equally unfashionable strain would 

 not be equally barred. The result of this discrimination in the 

 long run, and under our methods of study, would appear in the 

 form of sires of dams. To some extent it means, not that these 

 sires did not prodtice males, but that, being unfashionable, these 

 males had little opportunity. This probably does not account 

 for all differences, even though the turns and caprices of 

 fashion are harder on sires than on dams. 



It must not be forgotten in this connection that these 1 1 3 sires 

 constitute more than one half of the 207 greatest sires of the race. 

 They could not, therefore, have been so very unfashionable. 



5. Class i must be largely what it seems to be, breeders 

 of sires rather than of dams, because there is no reason why its 

 female offspring should have been suppressed. It is clearly 

 superior to Class 2, but inferior to Class 3.
