and geldings, and in 1890 for stallions. In 

 1876 the number of stallions having records 

 was less than 2 per cent, of registered stallions, 

 while in 1892 the stallions with records were 

 about 9 per cent, of those registered. Con- 

 sidering that at the dates in question stal- 

 lions which had been to the race track were 

 not patronized as liberally as those which 

 had not, it is probable that not over 5 per 

 cent, of the trotters born between 1874 and 

 1898 were by sires with records. Contrast 

 this with the fact that of the 180 animals 

 which trotted in 2 : 10, 121, or 67 per cent., 

 were by sires with records. An animal which 

 obtains a record acquires a good deal of 

 energy by his training and racing, and the 

 difference between 5 per cent, and 67 per 

 cent, is a clear indication that such an ac- 

 quirement by sires is of advantage in pro- 

 ducing 2 : 10 trotters. 



Taking the other factor of energy as repre- 

 sented by the ages of the sires of these 2 : 10 

 trotters, we find those ages ranging over 

 practically the entire scale of ages at which
