The 2: lO Trotters iol 



trotter. He was too early in history for that, 

 but as a grandsire and great-grandsire of ex- 

 treme speed he outranks all other horses. 

 Stallions which went to the race track, at the 

 time under consideration, usually retired to 

 the stud at about the age of seven, with very 

 few retiring more than two years earlier or 

 later than this age. George Wilkes retired 

 ten years later than this at the age of seven- 

 teen. If we should take the average age of 

 all horses with records, that average would 

 represent neither George Wilkes nor the 

 other horses, but would represent the average 

 age as being centered at a point between the 

 two where, in fact, practically nothing exists. 

 Such an average would, of course, be decep- 

 tive. To avoid this deception, George Wilkes 

 will be omitted from the averages, and that 

 animal will be considered later by himself. 



The details of different generations of male 

 and female ancestors, with illustrative dia- 

 grams, have been given in previously pub- 

 lished articles. Here these will be condensed 

 into a few tables.
