As yet very little has been accomplished in thisdirection. There is, to be sure, a Bolivian peachwhich is remarkable in that it has a globular stonevery little larger than a good-sized pea. The fruititself is of intermediate size and poor quality;moreover, it is produced sparsely, and the tree ispeculiarly subject to the peach maladies. Thefruit has been thought hardly worth crossing withour ordinary peaches on account of its inferiorqualities, yet the diminutive stone suggests that itwould be possible by such crossing to produce asuperior peach having an exceedingly small stone. Time and patience would, of course, be re-quired to carry out such an experiment, but itsresults could hardly be in doubt. It is possible, however, that the experiment ofreducing the size of the peach stone will proveless inviting than the attempt to remove the stonealtogether. My success in producing the stonelessplum points the way to a possible development [170]. Nectarine-Peach Cross This picture has peculiar interest as illustrating the greatdiversity of form that way he shown by fruit of mixed heritagegrowing on the same branch. As one parent is smooth-skinned andthe other fuzzy, interesting experiments may be carried outin noting the way in which these qualities aretransmitted to different members of theprogeny, particularly in the sec-ond generation.

And it is not unlikely that the Bolivian pea-stone peach, which has shown a propensity tominimize the stone, may be utilized advanta-geously in t
