 on my farm in the last few years, would 

 fill a very long column. 



I always have believed that, if the* prob-

 the question of human inheritance. I be- 

 lieved this, because the highly organized 

 race-horse is more like the high bred man 

 in his physical and nervous constitution 

 than any other animal. The laws of hered-

 govern the production of men. 



One of the greatest of living geneticists,

 ceivable." This is the opinion of every
