THE COTTAGE GARDENER AND COUNTRY GENTLEMAN, Juke 12, 1860. 
THE SCIENCE OF GARDENING. 
(Continued from page 73.) 
InaecSiNG differs from grafting only in having the scion still 
attached to its parent stem whilst the process of union with the 
stock is proceeding. It is the most certain mode of multiplying 
*>.n individual that roots or grafts with difficulty, but is attended 
with the inconvenience that both the stock and the parent of the 
scion must be neighbours. 
One of the most ingenious applications of inarching is suggested 
by Mr. Knight. If a fruit-bearing branch becomes denuded of 
its leaves above the fruit it has produced, this cither falls, or 
remains stunted and deficient in flavour, owing to being thus 
deprived of a supply of the elaborated sap or proper juice. In 
such case a branch having leaves of the same or of a neighbouring 
tree, may be inarched to the denuded portion of the branch, and 1 
the fruit will then proceed to maturity. Mr. Knight’s experiment , 
was tried upon a Peach tree, the fruit of which he was anxious 
to taste, but which produced that season only two Peaches, and 
from the branch bearing which all the leaves had fallen. 
Another excellent adaptation of inarching is where the same j 
tree supplies both the scion and the stock. Mr. Thompson thus 
describes this adaptation by M. Fourke to Pear trees at Corbcil, 
in France. The trees had been planted when large and irre¬ 
gularly grown, having, in some places, a redundancy, in others a 
deficiency, of branches. With the view of supplying branches 
where wanting, inarching the growing extremities of adjoining j 
shoots to the parts of the stem whenoe the horizontals should j 
proceed, was adopted. 
Supposing the branches of a tree are trained horizontally a foot | 
apart, with the exception of some where (lie buds intended to 
produce branches did not break, as is often the case ; then a 
shoot (a) is trained up, raid, when growing in summer, a small 
slice is taken oft’ ucar its extremity, and a corresponding extent , 
of surface immediately below the inner bark of the stem is cx- ; 
posed ; the two are joined together, and the point of the shoot ‘ 
(ii) is inclined in the direction to form the branch (c). 
The most remarkable feature in the trees at Corbeil, wa3 the 
uniformity of vigour in the respective branches. It appeared as 
if the supplied branches, c c c, had been allowed to grow in con¬ 
nection both with the stem at b b, and the branch from which 
they originated at ft a a, till their length and thickness corre¬ 
sponded sufficiently with that of the branches above and below 
them. This is a great advantage which the mode possesses over 
budding or side-grafting. At the distance of a foot apart for the 
horizontal branches, it takes as many years to cover the wall as 
the latter is feet in height; for although the leading shoot may 
grow three or four feet in length in a season, yet by shortening 
it to two feet, although the branches d d would be produced, the 
buds at b b, to furnish the intermediate stage, most probably 
would not. In fact, the attempt to form two tiers of horizontals 
in one season is generally followed by more or less disappoint¬ 
ment. The intermediate stage might, however, be readily sup¬ 
plied by the method above detailed ; and a wall twelve feet high 
might be covered as well in six years as it otherwise would be in 
twelve.—( Sort. Soc. Journal , ii.) 
The usual mode of inarching continues the same as it was 
when thus described by Abercrombie: — 
“ To propagate any tree or shrub by this met hod, if of the hardy 
kind, and growing in the open ground, a proper quantity of 
young plants for stocks must be set round it, and when grown of 
a proper height, the work of inarching performed; or if the 
branches of the tree you design to graft from are too high for the 
stock, stocks must be planted in pots, and a slight stage erected 
around the tree of due height to reach the branches, and the pots 
containing the stock placed upon the stage. 
“ As to the method of performing the work, it is sometimes per¬ 
formed with the head of the stock cut off, and sometimes with 
the head left on till the graft is united with the stock, though by 
previously beheading it the work is much easier performed, and 
the supply cf sap will be directed to the nourishment of the 
graft. 
“ Side Inarching -with a Tongue .-—Having the stocks properly 
placed, make the most convenient branches approach the stock, 
and mark in the body of the branches the parts where they will 
most easily join to the stock, 
and in those parts of each 
branch, pare away the bark 
and part of the wood two or 
three inches in length, and 
in the same manner pare the 
stock in the proper place for 
the junction of the graft ; 
then make a slit upward in 
the branch so as to form a 
sort of tongue, and make a 
slit downward in the stock 
to admit it; let the parts 
be then joined, slipping the 
toDgue of the graft into the 
Blit of the stock, making the 
whole join in an exact man¬ 
ner, and tic them closely to¬ 
gether with bass, and after¬ 
wards cover the whole with 
a due quantity of clay, or 
wax. After this let a stout 
stako be fixed for the sup¬ 
port of each graft, and so fastened as to prevent its being dis¬ 
joined from the stock by the wind.” 
Side Inarching without a Tongue is the most simple and most 
usual mode of inarching. A slice of bark and alburnum of 
similar dimensions in both stock and scion are removed at the 
point where they are intended to unite, as in fig. 1. These 
a. The stock, with an undar tongue 
prepared. 
b. The scion with upper tongue to in¬ 
sert into a. 
c. The stock and scion united. 
parts are placed face to face, so that the barks and alburnums of 
the two wounds arc brought in contact, as at a, in fig. 2. They 
are then bound firmly together with strips of bast mat, as re¬ 
presented by b. The whole is then enveloped with moss, to be 
kept moist, or by an egg-shaped mass of grafting clay. 
The operation being performed in spring, let the grafts remain 
in that position about four months, when they will be united, 
and they may then be separated from the mother-tree; in doing 
this be careful to perform it with a steady hand, so as not to 
loosen or break out the graft, sloping it off downwards close to 
the stock ; and if the head of the stock were not cut down at the 
time of grafting, it must now be done close to the graft, and all 
the old clay and bandage cleared away and replaced with new, to 
remain a few weeks longer. 
Observe, however, that if the grafts are not firmly united with 
the stock, let them remain another year till autumn, before you 
separate the grafts from the parent tree.
