A fruit-tree may be budded or grafted on seedling or cuttinggrown
stocks of the same species of plant, or 011 stocks of a
related species. The practice is determined wholly by t,he
c~hrapness of the stock and fhe ease with which it can be grown
and worked, except t.hat in the dwa.rfing of trees a speck1
definite kind of stock must be supplied. It does not. follow that
thtl stocks now c*ommonly used are intrinsically the best. The
subject is much in need of careful in\-estigation not only in the
nursery hut throughout the lifetime of the resulting orchards.
The choice of stocks ha:; usually not gone beyond the
spcties, whether, for esnmple, the cherry shall be worked OIL
rnahaleb which is PROI US MahaM or on the mazzard which
is I’rwl US II 2:2’ii~rv, whether cultivated persimmon shall be
budded on IIr’ospgms Kaki, or Il. virginiana or D. Lotus.
,Soon, ho\v\rt\.cr, we must refine our processes much more than
this. \Yv tlscrcisc particular care in the variety to he propagated
for the top or over-ground part of the plant. We must
also i3iiscriminate as to the variety, rather than the species, of
th.t: stock or under-ground part. We shall find ways to
pr0pagat.e varieties and strains of stocks as we now have ways
to reproduce exactly the varieties and. strains of the fruitbearing
or flower-bearing part. This may increase the expense
of the finished plant, but the time i; coming when we must
reduce the sources of failure to the minimum and be willing to
pay for the extra certainty. We must, foresee the time when
a man may plant an orchard with all human -. assurance of
