In many cas3s of experimentation, plums have been more 

 highly inter-fruitful than inter-fertile, some producing fruits 

 which contained abortive seeds. 



272. The peach. — Unhke practically all other fruits, 

 the peach, as a rule, is quite self-fertile and capable of set- 

 ting and maturing a crop when self- or close-pollinated. 



Fletcher reports, "The results of hand-pollinating 2939 

 Gold Drop peach blossoms in 1906 showed no benefit to this 

 variety from cross-pollination with St. Johns, Late Cran- 

 ford, or Lewis; the self-fertilized fruits were perhaps a trifle 

 superior." All experiments confirm this work in general 

 and the recommendation that peaches of one variety may 

 be planted in a solid block is standard, although growers 

 frequently feel that they prefer to mix them somewhat.
