_ This Vifcidity is very apparently difcovered on the leaden Beds of the 
Mills, as well as on the wooden Gutters, where the Juice in its Paflage de- 
pofits it; and its * faponaceous Quality is no lefs evident in wafhing the 
Cloths that have been any ways ufed in cleaning the Beds of the Mills, or 
hath any other way been foaked in the Cane-juice. 
The Clarification of the Liquor, as far as it is done in the firft Copper, 
is perfected after the more grofs Scum is taken off ; the remaining Impu- 
rity, as the Liquor boils, is tkimmed off from the four or five remaining 
Coppers or ‘Taches, into which the Liquor is fucceflively poured ; each of 
thefe being gradually lefs, as they are to contain a Quantity of Liquor ftill 
wafting as it boils. 
In conveying this to the fourth Copper, it is in its Paflage ftrained 
thro’ a thick Woolen Cloth, where it leaves all the Remainder of its Im- 
purities, that had efcaped the Scummer. 
After this a light white Scum is taken off ; and, when this ceafes to 
arife in any confiderable Quantity, and the Liquor, by long boiling, be- 
comes more of a Syrup than a thin Liquid, it is then poured into the firft 
Tache, and from this to a leffer, till it is conveyed to the laft. .When it 
hath here attained the due Confiftence neceflary to become Sugar ; it may 
be afferted in general, that no more than a feventh Part of the Whole 
remains; which Diminution is occafioned by the Impurities being {cum- 
med off, and the watery Particles evaporated. 
From this laft Stage, whilft of the Confiftency of a thick granulated 
Syrup, it isconveyed into a large Brafs Cooler, where it begins, as it cools, to 
fhoot into Cryftals, which are the genuine and effential Salts of the 
Plant. ‘Thefe are forwarded and helped to hoot, by gently ftirring the 
whole Mafs; by which means the Air is admitted to every Part, and the 
Particles of Sugar difengage themfelves from the clammy Subftance of 
the Melaffes. baibind ‘ 
If the Syrup be continued longer on the Fire, than is neceflary to bring 
it to a proper Thicknefs, the Particles of Sugar cannot grain, or cryftal- 
lize, when afterwards in the Cooler, for want of a fufficient intermediate 
Fluid; the whole Mafs in fuch a Cafe being too well united, to fuffer 
the Melaffes to feparate from it. 
On the other hand, if the Syrup hath not undergone a fufficient Eva- 
poration, the Grains or Salts will be: larger indeed, but clofe to each 
other ;. Hence feveral of them being too much feparated from their neigh- 
bouring Particles, they become too weak to refift fingly, and are therefore 
drained away in the intermediate Fluid, the Melaffes. Upon this Principle 
we may account for the Make of Sugar-candy, whofe large Cryftals are

_ Repeated Draughts of it are very efficacious, to remove the Effect of the poifonous Caffado-juice. 
From this Juice likewife, when mixed with Water, and fermented, is made a Drink, called the Sugar-Drink. 
This, tho’ it appears muddy, yet is very wholfome and diuretic.
