The Problem Stated 33 



lation to what they received, and then passed 

 the entire amount to the offspring, who added 

 to this sum his own accumulation. In fact, 

 a comparison of extraordinary animals with 

 the amount of energy accumulated by an 

 ordinary contemporary animal in a rather 

 more than normally active life indicates that 

 we should go back to the great-grandparents 

 and the great-great-grandparents for part of 

 the excess over that which exists in the 

 ordinary animal of the same breed. 



To account for the energy existing in such 

 an animal as a 2:10 trotter coming from 

 stock not having that capability, it is evident 

 that we should consider the accumulations 

 of two or three generations previous to the 

 animal itself. The fact that accumulations 

 of animal energy dissipate rapidly by reason 

 of idleness, and the additional fact that 

 animals used for breeding trotting stock are 

 frequently idle animals, makes it evident 

 that ordinarily such accumulations must 

 exist within two or three generations of an 

 animal of 2 : 10 quality. It does not follow
