Inarching differs from the other 
kinds of grafting, by preserving the 
scion attached to the parent plant 
till it has become united with the 
stock in such a manner as te derive 
its nourishment from it. For the 
mode of performing the operation,

To graft with success, the opera- 
tion is best performed in spring, im- 
mediately before the buds of the 
scion begin to expand; and, in 
general, the scion ought, in this re- 
spect, to be in advance of the stock ;

a result which is obtained by cutting 
off the scions from the parent plant 
in the winter season, and inserting 
their ends in the soil in a cool shady 
place in the garden till they are 
wanted in spring. In performing 
the operation, it - necessary to have

| a very sharp knife ; for if the slight. 
| est roughness is left on the parts of 
ithe scion and the stock which are 
ito be united, their perfect union 
| cannot be effected. ‘The operation 
ought also to be performed with 
| rapidity, so as to expose the naked 
| sections of the scion and stock for 
as few moments as possible to the 
atmosphere. When the plants to be 
| grafted are in pots, they should im- 
|mediately afterwards be placed in 
a gentle heat, and kept moist; and, 
if covered with a bell-glass, so much 
the betier. ‘The latter practice may 
be considered as essential in the 
case of grafted Orange trees, Ca- 
mellias, Rhododendrons, Daphnes, 
Arbutus, Magnolias, &c. Grafts 
made in the open air, on very small 
plants, may sometimes be covered 
with hand-glasses, or slightly shel- 
tered or shaded till they have begun 
to grow ; and the soil may be cov- 
ered with litter, or rotten tan, or 
leaves, to retain the moisture. 
Where no pains are spared, the soil 
may be warmed immediately after 
grafting, by watering it with a few 
pots of hot water. After the scion 
has made shoots a few inches in 
length, the clay may be removed 
and the matting loosened; but care 
must be taken not to do this too 
soon. The proper time may always 
be. known by observing whether the 
edge of the scion exhibits a granu- 
lating process, closely uniting it 
with the stock. In general, in the 
course of the month of August, all 
the matting from plants grafied in 
the open air may be removed; and 
with those under glass, this may be 
done much sooner. 
Grafting clay is made of clayey 
loam, or brick-earth, mixed with 
about a fourth part of fresh horse- 
dung, free from litter, and a portion 
of hay cut into pieces about an inch 
in length, adding a little water, and 
beating the whole together for seve- 
ral hours. On asmall scale, how
