9 2 Dynamic Evolution 



inquiry into the history of those sires which 

 had no records shows, as far as it shows any- 

 thing at all, that the majority had some 

 actual training as colts with the prospective 

 intention of sending them to the track. 

 Some of them trotted in races in less than 

 standard time but got no records because 

 they did not head the procession under the 

 wire. 



The general facts may be set out in another 

 form by means of the following tables: 



Sires with No Records 



13 Sires of Stallions average age: 13.61 years 



25 Sires of Mares average age: 10.80 years 



21 Sires of Geldings average age: 10.76 years 



Sires with Records 



45 Sires of Stallions average age: 9.80 years 



41 Sires of Mares average age: 9.80 years 



35 Sires of Geldings average age: 8. 11 years 



With systematized breeding operations and 

 a Trotting Register in which to keep track 

 of trotting stock, it would seem as if there 

 would be no difficulty in obtaining full in- 

 formation about the dams of such animals
