THE CHERRY 135 



a given lot of four thousand, let us say, one thou- 

 sand will be BB, two thousand will be Bb, and 

 one thousand will be bb. 



And precisely the same difficulty in selection 

 confronts the experimenter that confronted him 

 before. 



If he could only know which are the pure dom- 

 inants and which the mixed one, all would be 

 well. 



But not only is it impossible for him to know 

 this, but he may not be able even to determine 

 with certainty, from examination of the foliage of 

 the seedlings, which ones belong to the group of 

 three thousand that bear the dominant factor 

 (either BB or Bb), and which to the group of 

 one thousand that bear only recessive factors 



It must be borne in mind that the experimenter 

 is really considering a large number of qualities, 

 and it must be understood also that there may 

 not be any clearly established point of correlation 

 between the foliage or stem or buds of the seed- 

 ling and the qualities of its future fruit as regards 

 the matter of size ; though by practice one can al- 

 most certainly select those which will bear the 

 fruit desired by the foliage, growth, and buds; 

 for large, thick leaves and large short- jointed 

 wood and prominent buds are an almost certain
