mucilaginous and more or less un&ganized substance, and in
this st,age it most readily repairs and unites wounded surfaces ;
and for this reason the grafting and budding of old trees are
usually performed in the spring. Later in t,lie season, the
cambium Iwumw firmer and more dift’erentiated, and union
of wc,otly parts is more uncertain.
It, is necessaq- to cover the wounds to check evaporation
fr(!m the tissues. In outdoor work, wax is commonly used
for all kinds of grafting that wound the wood itself, but in
budding, the loosened bark, bound down securely by a bandage,
afiords sufficient protection. It is commonly supposed that
an ordinary cleft-graft cannot live if the bark of the stock
immediately adjoining it, is seriously wounded, but the bark
really- serves little purpose beyond protection of the tissues
beneath. ,I cion will grow when the bark is mostl?’ removed
from the stub, if adequate protection is given which will not
interfere with the formation of new bark.
The cion must always bear at least one good bud. In most
cases, only buds that are mature or nearly so are used, but. in
the grafting of herbs very J*oung buds may be employed.
These simple requirements may be met in an almost innumerable
variety of ways. The cion or Id may be inserted in the
root, crown, trunk or any of the branches ; it may be set simply
