Average for all sires, 2 years 7 months. Omitting the old-timers,

The deduction which the compiler of these statistics reached was that 

 the same law which governs in thoroughbred horses and in the trotting 

 family ruled in dogs: that there is one supreme sire-power source, and but a 

 few dam-power sources, the proof of the latter conclusion being that of the 

 thirty dogs named in these tables nineteen trace back to six bitches 

 Merry Fan, Old Hall Vera, Pepita, Parbold Dolly, Sweet Lassie, and 

 Ruby III. Astrologer traces to the dam of Charlemagne, and Wellesbourne 

 Councillor to a sister to General Trefoil.
