and in the prick't Circles between the ftverall coats of Wood^ 
but alfo through the very Body of the Wood. For, fcvc- 
ral young Birches being nimbly cut off at one blow with i 
ftarpeaxe, and white paper immediately held hard upon the 
topp of the remaining trunk, we ftuck downepinsinall the 
points of the paper as they appear'd wet : and at laft, whea 
the moft of the paper became wet , raking it away , but lea-; 
vingthe pins flicking , we found them without any order, 
fome in the Circles, aad fome in the Wood between. And 
to confirm this further , we caufed the Body of a Tree to be 
cutofFaflope, and then cut the oppofitc fide aflope like- 
wife, till we brought the top to a narrow edge 5 ordering the 
vHiatter fo, that the whole edge conCfted of part of a coat of 
Wood, and had nothing of a prick't Circle in it, which 
notwithftmdiag , the Sap afcended to the very top of this 
edge, and wetted a paper laid upon it; 
8. To fod out the motion of the Sap, whether it afcen- 
ded onl/, or defcended alfo5 we bored a hole in large 
Birch i out of which a drop fell every 4th or jthpulfe. Then, 
about a hands breadth juft under the hole , we favv'd into the 
Sody of the tree, deeper than the hole: whereupon the blee- 
ding diminifh'd about onehalf>, and having (aw'd luft above 
this hole to the fame depth, the bleeding from the Holecea- 
s'd quite 5 and from the faw'd furrow below decreased about 
half: and it continued bleeding a great while after at both the 
fawM furrows, the hole in the middle remaining dry. We 
repeated this with much the like fuccefs upon z Sycamore. 
9. Some Trees of the fame kind and age bleed a great 
deal fafter and fooner than others 5 butalways Old trees foe- 
. ner and fafter than Young.
