notch, viz. to keep the scion in its 
place. When the stock is of much 
larger diameter than the scion, the 
appearance of this graft is, of course, 
quite different, and the latter is put 
on at one side, in order that its in- 
ner bark may be closely united with 
that of the stock. This is the com- 
mon mode of grafting fruit-trees in 
the nurseries.

Slit, or Cleft-grafting, is per- 
formed by first cutting over the 
stock, and next making a slit or 
cleft in it; then paring the scion 
on both sides, so as to form a wedge, 
narrower at the inner edge; and, 
after inserting it in the cleft, tying 
it and claying it as before. This 
mode is well adapted for grafting 
one succulent plant on another ; as, 
for example, in the Cacti tribe, 
grafting an Epiphyllum on a Peres- 
kia, as shown in fig. 24, or for 
grafting ligneous Peonies on the 
tubers of herbaceous ones, as shown 
in figs. 25 and 26. In fig. 25, a 
is the stock already notched; and, 
in fig. 26, 6 is the prepared scion, 
and ¢ the grafted plant. 
Side-grafting is shown in figs. 
27 and 29, in which f is the stock, 
from which a portion is cut out, 
against which the scion e, also 
somewhat thinned down, is to be 
applied and made fast, as Shown in 
fig. 29 at g. This being done, the 
graft is covered with grafting-wax 
or clay, as usual. It will be ob-

served, that by this mode the head 
of the stock is not cut off, but is 
left on, in order to draw up the sap, 
and also to prevent the stock from 
being disfigured in the event of the 
death of the scion. There is an- 
other mode of side-grafting, as 
shown in fig. 30, in which it will 
be observed, that the lower end of
