308 LUTHER BURBANK 



Cherries, Peaches, Apples, and Plumcots ; and an 

 elaborate series of experiments with Cereals and 

 Grasses these represent a few main lines of the 

 work that has occupied attention in recent years, 

 and will serve to suggest the further lines of 

 action that will claim attention in the years to 

 come. 



Meantime the present publication, giving the 

 first complete and authoritative account of my 

 work that has ever been attempted, comes forty- 

 five years after the development of the Burbank 

 potato, which marked the beginning of my plant 

 development. Yet I have reason to hope that 

 there are years ahead that will prove even more 

 productive than any years of the past perhaps 

 in their ultimate importance more productive 

 than all the forty-five years of past effort, as 

 these experiments are necessarily cumulative.
