have been made to carry as many as 600 varying seedling grafts. The 

 Bartlett plum, cross of the bitter Chinese Simoni and the Delaware, 

 itself a Simoni hybrid, has the exact fragrance and flavor of the Bartlett 

 pear. The Climax, a successful shipping plum, is also a cross of the 

 Simoni and the Japanese triflora. This Chinese Simoni produces 

 almost no pollen, but few grains of it ever having been obtained. But 

 these few grains have enabled Burbank to revolutionize the whole plum 

 shipping industry. The sugar prune, which promises to supplant the 

 French prune in California, is a selected product of a second or third 

 generation variety of the Petite d'Agen, a somewhat variable French 

 plum.
