392. Obfervations on the Growth of Trees 
the wound fo as the air may be prevented from carrying off the 
moifture, which, when uncovered, flows from the wound, the 
buds above will grow nearly as well as if the wound was not 
made.: To fuppofe that new vefiels, formed at the root, afcend, 
and feeking the buds, by paffing round the incifion, im- 
mediately find them, is too ludicrous an obje&ion to be feri- 
oufly noticed. Let us, then, confider the. buds which are 
formed in the bofom of every leaf. 
One ef thofe buds, rended from its. parent Eig. ond inferted 
het bark of another tree of the fame. genius, will grow as well 
as if it had been continued where nature placed it, and bécome 
“a compleat tree. Here, at leaft, there isa certainty, that there 
‘are no fibres calculated to füpport it, yet it will grow ; and the 
Whole tree, above the infertion in the ftock, thus fpringing 
from å fofter-bud, is exactly of the fame nature in all refpects, 
and produces the fame fruitas the tree from which the bud 
was taken. This is the wonderful circumftance, which, 
though often attempted, has never been clearly accounted for. 
. We thall proceed to enquire, then, how buds inferted in fo- 
reign ftocks attain their growth. 
. Whena bud is bro't into contact with the ftock, and the bark 
of the ftock paffed round and upon the bark laid in with the bud, 
„the fap very quickly forms a gum, which glues them together, 
and ftops the mouths of thofe veffels which had been torn by 
Aeparating the bark and bud from the parent tree. Whoever 
examines the fact, muft be convinced, that the bud, thus laid 
in, never has any further adherence to the ftock ; but remains, 
during the life of it, liable to be feparated from it by diffolving 
that gum ; and, from this circumftance, the fize and fhape of 
‘the wood, or bark, laid in with the bud, may be plainly difco- 
vered
