through which the peach also may at some time 
become stoneless. 
And it is not unlikely that the Bolivian pea- 
stone peach, which has shown a propensity to 
minimize the stone, may be utilized advanta- 
geously in the course of these experiments. 
It is true that no stoneless peach of whatever 
quality is known, comparable to the original wild 
builace of Europe, that gave the opportunity in 
the development of the stoneless plum. But, for- 
tunately, I have been able to demonstrate that the 
peach may be hybridized with the plum. I have 
made the hybridization successfully with both the 
Japanese plum and the Chickasaw plum. 
Should it prove impossible to hybridize the 
peach directly with a stoneless plum, one of these 
peach-plum hybrids might perhaps be made to 
bridge the gap. 
No doubt a vast deal of ingenuity would be 
required to find the combination that would work 
out successfully. But it was shown in the case of 
the stoneless plum that it was possible to re- 
assemble the good qualities of the fruit of one 
parent and the stoneless condition of the other 
in the progeny of the hybrids of later generations. 
There is no obvious reason why the same thing 
might not be done in the case of the peach. 
The possibility seems the greater because the
