fap of other branches 5 efpecially when fomc 
months after the inoculation, the ftock of 
the inoculated JeflTamine is cut off a lit- 
tle above the Bud j whereby the ftock , 
which was the counter afting part to the 
ftem, being taken way, the ftem attradls 
more vigoroufly from the Bud. 
Another argument for the circulation of 
the fap, is, that fome forts of graffs will 
infeft and canker the ftocks they are grafted 
on: But by Exper. 12 and 37, where mer- 
curial gages were fixed to frefh cut ftems of 
trees, it is evident, that thofe ftems were 
in a ftrongly imbibing ftate 5 and confe- 
quently the cankered ftocks might very like- 
ly draw fap from the graff, as well as the 
grafF alternately from the ftock 5 juft in the 
fame manner as leaves and branches do 
from each other, in the viciftitudes of day 
and night. And this imbibing power of the 
ftock is fo great, where only fome of the 
branches of a tree are grafted, that the re- 
maining branches of the ftock will, by their 
ftrong attraction, ftarve thofe graffs 3 for 
which reafon it is ufual to cut off the great- 
eft part of the branches of the ftock, Icav.
