is evident, that the branch b attrads fap 
at x with great force : And by this pre- 
fcnt Experiment, ’tis as evident, that fap 
will be drawn as freely downwards from 
the tree to x> as from c to x y in cafe the 
end € of the foot were in the ground ; 
whence 'tis no wonder, that the branch b 
thrives well, tho* there be no circulation 
of the fap. 
This Experiment 41, and Experiment 26, 
do alfo fhew the reafon why, where three 
trees (Fig. 24.) are inarched, and thereby 
incorporated at x and the middle tree 
will then grow, tho* it be cut off from its 
roots, or the root be dug out of the ground, 
and fufpended in the air 5 ‘Viz. becaufe the 
middle tree b attracts nourifhment ftrongly 
at x and z y from the adjoining trees a c y 
in the fame manner as we fee the inverted 
boughs imbibed water in thefe Exper. 26 , 
and 41. 
And from the fame reafon it is that 
Elders, Sallows, Willows, Briars, Vines, 
and moft Shrubs, will grow in an invert- 
ed ftate, with their tops downwards in 
the earth.
