Vegetable Staiicks. \ 17 
at 7 a. m. A pufhed 1 inch, C 1 -J- 4, but 
towards noon they all three fucked. 
I have frequently obferved the fame dif- 
ference in other Vines, where the like gages 
have been fixed at the fame time, to old 
and young branches of the fame Vine, viz. 
the oidcft began firft to fuck. 
I11 this Experiment we fee the great force 
of the fap, at 44 feet 3 inches diftance from 
the root, equal to* the force of a column of 
water 30 feet 1 1 inches -f- 4 high. 
From this Experiment we fee too, that 
this force is not from the root only, but 
muft aifo proceed from fome power, in the 
fern and branches : For the branch B was 
much fooner influenced by changes from 
warm to cool, or dry to wet, and vice versa, 
than the other two branches A or C 5 and 
B was in an imbibing ftate, 9 days before 
A , which was all that time in a ftate of 
puftiing fap 3 and C pufhed 1 3 days after B 
had ceafed pufhing, and was in an imbi- 
bing ftate. 
Which imbibing ftate Vines and Apple- 
trees continue in ail the fummer, in every 
branch, as I have found by fixing the like 
gages to them in July.
