Field, Forest and Farm: Things interesting to young nature-lovers, including some matters of moment to gardeners and fruit-growers

“The implement here required is the grafting-knife, furnished at one
end with a very sharp blade, and at the other with a short spatula of
bone or very hard wood. The first thing to do is to remove the bud to
be transplanted. On a branch in which the sap is working we make with
the grafting-knife a transverse cut above the bud and another below;
then, holding the branch in one hand and the grafting-knife in the
other, as the picture shows, we remove the strip of bark lying between
these two cuts and delimited laterally by the line gg´g´´ and its
opposite, in figure F. This strip, which we call the shield, is shown
by itself in H. The leaf that sheltered the bud in its axil has been
removed, but the base of the stem of this leaf has been left and will
be useful later for taking hold of the shield and handling it more
conveniently. The shield must be cut away without any tearing and in
such a manner that no sap-wood is left clinging to the bark. The latter
must be perfectly intact, especially in its inner layers, the seat of
vital activities. Finally, the bud should have its proper complement of
young, greenish wood, which constitutes the germ, the very heart of the
bud. Should this germ be removed by unskilful manipulation, the bud
would have to be thrown away, for the graft would surely fail.
“The next step is to make a double incision in the bark in the shape of
a T, penetrating as far as the wood but without injuring it. With the
spatula of the grafting-knife the two lips of the wound are raised a
little while the bud with its shield is taken up by the piece of
leaf-stem attached to it and inserted between the bark and the wood.
All that now remains to be done is to draw the lips of the little wound
together and bind the whole with some sort of material sufficiently
pliant and elastic not to compress and finally strangle the bud as it
develops. A rush, a slender thong made of a long and flexible
grass-blade, or, better still, a piece of woolen yarn is well suited to
the purpose. But if despite all precautions the ligature should after a
while prove too tight on account of the swelling of the graft, it would
be necessary to loosen it without delay. As soon as the graft has
‘taken,’ as we say, the young shoots starting out on the stock are
gradually suppressed in the cautious manner prescribed for
cleft-grafting.
“When the stock is too small to receive a bud in the usual manner, the
following expedient is resorted to. From a shoot of about the same size
as the stock a rectangular strip of bark with bud attached is cut with
four incisions of the grafting-knife. This strip is immediately laid
upon the stock to serve as a pattern while the point of the knife is
passed all around it. In this way there is cut from the stock a strip
of bark having exactly the same shape and size as the pattern, which
latter is thereupon inserted in the vacant place and made fast there by
a ligature. This process may not inappropriately be called veneering.
