THE STANDARDBRED HORSE I2g 



"3. A mare whose sire is a registered standard trotting 

 horse, and whose dam and granddam were sired by regis- 

 tered trotting horses, provided she herself has a trotting 

 record of 2.30 or is the dam of one trotter with a record 

 of 2.30. 



"4. A mare sired by a registered standard trotting 

 horse, provided she is the dam of two trotters with 

 records of 2.30. 



"5. A mare sired by a registered standard trotting 

 horse, provided her first, second and third dams are each 

 sired by a registered standard trotting horse." 



The pacing standard is similar except the word "pacer" 

 is substituted for the word "trotter;" "pacing" for the 

 word "trotting;" the speed standard 2.25 for 2.30; and 

 the addition of a sixth paragraph, which is as follows : 



"6. The progeny of a registered standard trotting horse 

 out of a registered standard pacing mare, or of a regis- 

 tered standard pacing horse out of a registered standard 

 trotting mare."* 



Influence of the standard. — Recordingperformance when 

 making the standard has been a most important factor in 

 developing extreme speed in the trotter and pacer. This 

 method not only distinguishes the slow and fast horses, 

 but from the records the breeder can determine those that 

 are actually producing fast horses. In breeding, the slow 

 ones are discarded and the fast ones are propagated, 

 which, in connection with improved conditions, enables 

 us to get still faster producers. Again the slow ones are 

 discarded and the fast propagated, with the results that 

 the maximum speed of the race has been raised. The 

 following tables show the reduction in time for a mile 

 track with horses in harness between 1810 and 1912. The 

 table gives the name of the horse, place of the race, date 

 and time.
