Nectarine-Peach 
Cross 
This picture shows 
the crossbred fruit cut 
open, revealing the stone. 
It will be seen that in 
these specimens the stone 
is unduly large, and that 
the fruit clings to the stem. 
Where peaches and nec- 
tarines are growing in the 
same neighborhood, cross- 
breeding experiments are 
often made by the bees, 
without human 
interference.
