ON THE CHERRY 
sider only a single quality in detail, keeping in the 
background of our minds the idea that the actual 
experimenter is at all times considering almost 
innumerable other qualities as well. 
The one quality that we will consider at the 
moment is, let us say, the matter of size. We wish, 
for some special purpose, to develop a cherry that 
shall be a giant among cherries, yet which of 
course shall combine size with quality. 
Now we have at hand a cherry that bears very 
large fruit of poor quality. We have also at hand 
a tree that bears small fruit of delicious quality. 
Our first step will be to transfer pollen from the 
stamens of one of these to the pistils of the other. 
We carefully mark the limbs bearing the hybrid- 
ized flowers; and subsequently we gather the fruit 
and save the seed and in due course plant it and 
nurture the seedlings by methods hitherto fully 
explained. 
So when a year and a half has passed from 
the inauguration of our experiment we have a 
row of hybrid seedlings ready for grafting. 
The one thought that is uppermost in our mind, 
for purposes of the present exposition, is that of 
securing a plant that will bear fruit of large size. 
Now we have learned that there are certain cor- 
relations of parts that will enable the plant ex- 
perimenter to predict, from the quality of the
