122 Dynamic Evolution 



hundred sons and about the same number of 

 daughters ; while the remaining and less valua- 

 ble half came from about 700 sons and the 

 same number of daughters. Now, when we 

 take these sons and daughters which were the 

 best in the production of performers, we find 

 that they (the sons and daughters) were 

 produced in small fractions of their sires' 

 lives, and that these fractions represent the 

 particular times in life when the sires were 

 in their best dynamic development. Briefly, 

 we have traced the energy conditions of six 

 sires through two generations to three thou- 

 sand grandchildren, and have shown that the 

 inherited energy found in the grandchildren 

 represents and corresponds to the energy 

 conditions in the grandsires at the points in 

 their lives where the lines of descent begin. 

 Outside blood in two generations, and inter- 

 vening work, influence individual cases, some 

 of them widely, but in large masses like these 

 the grandchildren accurately represent their 

 grandsires. 



These facts may appear so extraordinary
