before a Microfcopc, and caufed the Painter to draw it aS 
it appeared to him, as you may fee in Fig. 2. H I K Li 
where you may obferve the Veffels or Canals do not rua 
longways, but circularly about the Wood ^ which be- 
ing fo, the faid Veffels can't remain long whole, but rauft 
from time to time be broken in pieces. 
When 1 cut crofs the Wood of a Cherry Tree, which 
was about a year old, in order to (hew the Painter the 
Horizontal Veffels that are derived from the Wood to the 
Bark, and whereby the Bark receives its Growth and Nou- 
rifhment, the Bark, by reafon of the Softnefs and Flexibi- 
lity of thofe parts that lay next the Wood, did always 
yield fo much, that it WM impoffible for me to ftiew him 
the faid Veffels. 
Upon this I turn d my Thoughts upon the Beach- wood, 
becaufe the greateft part of that Wood is cloathed with a 
Red Bark, which fticks clofe to the Wood, and grows 
yearly thicker ^ and upon the outfide of that Bark there 
is produced a Whitifli fort of Bark feveral times in a year, 
which falls off from the Wood as if 'twas pill'd 3 but this 
only happens in Beach Wood of an ordinary thicknefs 3 
for in the thickeft Wood this Peeling or Scaly fort of Bark 
is not produced, and then the Bark grows exceeding thick 5 
but the moft part of fuchBark is thruft away, and remains 
as it were without Nouriftiment 5 and in fuch there is no 
outermoft Scaly fort of Bark produced. 
I fteep'd this kft mentioned Wood in Water, becaufe it 
was very dry, that I might the better cut it through with 
a (harp Knife, whereby the Afcending and Ho; izoiKal Vef- 
fels or Canals might receive the ieaft damage in cutting. 
Fig. 3. L M N O P QK reprefents a fmall particle of the 
laft mentioned Wood, as it were cut acrofs, in which the 
Afcending Veffels or Canals, both great and Gnall, are 
eafily feen, and between which run the Horizontal Veffels^ 
which receive their Juices frojn the Afcending ones.
