 form of heredity, than even that of a bear which 

 seemed to have inherited the intelligence and skill 

 to fish?"

 by-product of your work is fully as interesting as 

 the work itself — the viewpoint which you get on 

 the forces which control life is of even greater 

 attraction to me than the wonderful productions 

 which you have coaxed from the soil." 



"A by-product, no," said Mr. Burbank; "these 

 things are a vital part of the day's work. Heredity 

 is more a factor in plant improvement than 

 hoes or rakes; a knowledge of the battle of the 

 tendencies within a plant is the very basis of all 

 plant improvement. It is not, as j'ou seem to think,
