J/t let able Statkb. 129 
I repeated this Experiment with a large 
T^uke-Cherry branch, but could not perceive 
more moifture at the upper, than the lower 
part of the gap, which ought to have been, 
if the fap defeends by the laft year's wood 
or the bark. 
It was the fame in a ^ince-branch as 
the ^uke Cherry, 
N, B. When I cut a notch in either of 
thefe branches, 3 feet above r, at q, I could 
neither fee nor feel any moifture, notwith- 
ftanding there was at the fame time a great 
quantity of water palling by 5 for the branch 
imbibed at the rate of 4, 3 or 2 inches per 
minute, of a column of water which was 
half inch diameter. 
The rcafonof which drynefs of the notch 
q is evident from Experiment ii, viz, 
becaule the upper part of the branch above 
the notch imbibed and perfpired 3 or 4 
times more water, than a column of 7 
feet height of water in the tube could im- 
pcll from the bottom of the ftera to q, 
which was 3 feet length of ftem \ and con- 
fequently, the notch muft neceftarily be 
dry, notwithftanding fo large a ftream of 
water was palling byi^i^/^.becaufe the branch
