effort at hybridizing the diversified races that 

 were brought together for the purpose of these 

 comprehensive experiments. 



I have said that some notable results were 

 obtained almost from the outset. 



As illustrating this, it may be recalled that, 

 whereas the first hybridizations between the Jap- 

 anese seedlings and plums of European and 

 American stock were made in 1888, there were no 

 fewer than six varieties of hybrids in my orchard 

 in the season of 1893, only five years later, that 

 were considered worthy of introduction and that 

 were able to take rank at once as superior in some 

 regards to any plums at that time known. 



Two of these, named respectively the Dela- 

 ware and the Hale, were hybrids of a double ori- 

 ental stock, one parent being the Kelsey, a Jap- 

 anese plum introduced by the orchardist whose 

 name it bears, and the other my Japanese 

 Satsuma. 



A third was a hybrid between a Japanese plum 

 named the Sweet Botan, or Golden, and the Rob- 

 inson, an American plum of the Ghickasaw race. 



Two others were crosses of the Robinson and 

 Abundance. 



The sixth was a cross between the Kelsey and 

 the Burbank, its ancestral strains being therefore 

 Japanese. This plum was first named Perfection,
