©a every fide of the Tree, fome deeper, and fome fhal!ower 3 
with a good large Auger 5 and one quite through floaping. 
From which Experiment, after various tryals, may be found the 
difference of theSip rifiag on the North and South, and fo like- 
wife of that which comes from the Bark onely peei'd off, and 
tha&which afcends in the inner part of the Tree, The weight 
alfo may be compared of that which iffues from the Bark, with 
thar, which iffues from the Body. The internal Heart- fap may 
alfo be drawn apart,by boring a fmaller Auger- hole in the middle 
of a greater, and fitting it with a long pipe, adjufted to that in- 
ner orifice. If no difference be found in thefe, the preemp- 
tion will be greater, that the difference of Heart ( as when they 
call heart of Oake ) and Saf in Timber is not from the plenty or 
fcarcity of fap, but from the feafon of felling. This Interception 
of the Heart fap may have an effed analogous to the boring out 
the Heart. 
To the 5 th. Dr. 5. faith I anfwer Experimentally, That if a 
Circle be drawn round about any common Englifli Tree, as 
Oak , Elme, Foflar&c. by Incifion to the Timber (how thin 
foever the Knife be ) fo that no part of the Rind or Bark to the 
very folid Timber be un-cut, the Tree will die from that part 
upwards. Onely the Afhe, ( of all that I could try ) will grow 
on, and profper notwithftanding the incifion. My Brother 
{T. B. ) (hew'd me fome old and huge Ajhes, which were bared 
of the Birk by the Deer, from the root 4 feet upwards quite 
round $ yet they had continued their growth many years, and 
fome parts of the Bark, which were left in few places not fo broad 
ss the palm of my hand 3 had a frefh verdure more lively then 
the parts of the Bark which remaia'd above the baring. Yet 
if fome Incifions by hackings be made, or if the Branches of 
fome Fruit-trees ( especially thi Gemet-mjle ) be quite bared 
under a knot near the body of the Tree, and that knot and bare 
part be well cover'd with loame or good mould in $me y that 
branch will not onely farvive, bat will be apt to take root and 
become a young Tree of fpeedy growth, if cat off below the 
baring, and fet at a fit depth at the end of Autumn^ or abouc 
Candkmts rather. Where fuch tranfver fe hackings are made,, 
or Contufions in the Bark 3 many Vegetables are apt to gather
