gating tor moi'e than one generation from tliis stock, then I believe 

 it would be good economy to take such stock at prices in advance of 

 those which are charged for the ordinary stock. 



In conclusion I would sum up the whole question by saying that 

 plant pedigrees of the right kind are worth paying for, but before pay- 

 ing for them it is well to be sure that the pedigree represents more 

 than a single generation. 



DISCUSSION 



Mr. Yeager: The professor has got us fellows of the laity in pretty 

 deep water. We unscientific fellows, this is very mysterious to Ub. 

 There are some things about it we do not understand. I understand 

 from what the professor says, that there are some things that are su- 

 perior to others in the nursery business, for instance, these trees. We 

 all know that there is now and then a tree that shows superior merit 

 in the production of fruit. But I am not quite clear yet about his argu- 

 ment as to whether you can take the scion^i from this limb, — we will 

 say it is a limb, and not the whole tree as he illustrated in the matter 

 of the grape vine. I am certain you did not find out whether the grapes 

 growing on that sport of the Concord were as good as the ones from 

 which you took the seeds. Do I understand you to say, professor, that 

 if you take the scions from this sport or apple tree, and propagate it 

 from that, as the nurserymen do, that each one of these scions taken 

 from that will. reproduce the identical kind of apple that grew on that 

 identical sport or limb. Isn't there always a tendency to revert back 

 to the fruit that grew on the other part of this tree, not known as the 

 sport. And is it fixed and certain that the wood taken from that identi- 

 cal limb will reproduce the apples or fruit grown on that identical limb. 

 About the apple, will you state whether you think it will revert, and 

 will you also state whether you think scions taken from a healthy tree, 

 a bearing healthy tree, producing fine fruit for a terjn of years and 

 propagated in the nursery row over here, and those taken from the 

 yearling out of the nursery row, do you know anything about what those 

 will produce, and you know they are healthy, which in the end, if taken 

 for a long period of years will produce the same strain of apples. 



Professor Beach: There is a gi'eat deal of conclusion about that. 

 We need more facts before we can form safe conclusions in regard to 

 these matters, and 1 am frank to say that the best evidence does not 

 reveal much, and those who have studied the things know comparatively 

 little about the subject. But we do iiave some facts. In the case of the 

 red twenty-ounce to which I referred, that held true under propagation. 

 The scions taken from the sport which were scions of the west side of 

 the tree, when those came into bearing they bore the same kind of fruit 

 as the original sport. Now you may have a large Wealthy apple tree, 

 which is due to the location in which it is grown. The Winesaps that 

 are produced in southern Kansas are nor the same type that are grown 

 at Woodbine, Iow:i. Tlici-i- ,mo differences in (Mivironment, and that fact
