LUTHER BURBANK 



I should of necessity give first place to the work 

 of development of the races of Spineless Cactus, 

 which reached a commercial stage in 1904. The 

 work with the Indian Corn, including, incident- 

 ally, the development of the Rainbow Corn; the 

 development of the giant Amaryllis; the perfec- 

 tion of new races of Shasta Daisies; the develop- 

 ment of new Roses, Gladioli, and some scores of 

 other flowers; varied work with the Poppies; the 

 development of new races of Giant Crimson win- 

 ter rhubarb; the production of the Sunberry; new 

 Plums, Prunes, 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 fur- 

 ther 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 

 years after the development of the Burbank po- 

 tato, which marked the beginning of my plant 

 development. Yet I have reason to hope that there 

 are years ahead that will prove even more pro- 

 ductive than any years of the past perhaps in 

 their ultimate importance more productive than 

 all the forty years of past effort.
