It has taken us about twelve years to accom- 
plish this result. And even now our new fruit 
must be propagated by grafting and budding, for 
it cannot be depended upon to breed absolutely 
true from the seed. 
The recessive factors for size and for color, as 
we have seen, are in its germ plasm; and these 
will make themselves manifest in the progeny. 
But so long as we confine ourselves to the 
method of grafting, we may hold the type of the 
new variety and spread broadcast our big red 
cherry with its combination of desirable qualities, 
with full assurance that, given reasonable condi- 
tions as to soil and climate, it will reproduce for- 
ever the qualities of the patrician fruit, the ances- 
tral history of which we have just traced. 
INVITING OPPORTUNITIES 
I have thought that by thus tracing in detail 
the history of a single experiment, paying heed 
chiefly to a single quality, but reminding the 
reader from time to time that other qualities can- 
not be ignored, we could perhaps gain a clearer 
notion than would otherwise be possible of the 
practical steps through which a new form of fruit 
is developed. 
It is through such series of experiments, lead- 
ing sometimes forward and sometimes backward 
in successive generations, that the four hundred
