The juice from the mill ordinarily contains eight 
parts of pure water, one part of sugar, and one 
part made of gross oil and mucilaginous gum, with 
a portion of essential oil. The proportions are 
taken at a medium ; for some juice has been so 
rich as to make a hogshead of sugar from thirteen 
hundred gallons, and some so watery as to require 
more than double that quantity. By a hogshead X 
mean sixteen hundred weight. The richer the 
juice is, the more free it is found from redundant 
oil and gum ; so that an exact analysis of any one 
quantity of juice, would convey very little know¬ 
ledge of the contents of any other quantity.* 
The above component parts are natural to, and 
are found in, all cane-juice; besides which, the 
following matters are usually contained in it. Some 
of the bands or green tops, which serve to tie 
the canes in bundles, are frequently ground in, and 
yielded a raw acid juice exceedingly disposed to 
allowing four hours out of the twenty-four for loss of time, the return 
■per diem is io,oco gallons \ being equal to 36 hogsheads of sugar of 16 
cwt. for every week during the crop, exclusive of Sundays.—Few wa¬ 
ter mills can exceed this. The iron-work of the mill in question, as well 
as of most of those which have been made on Mr. Woollery’s model, 
was prepared at the foundery of Mr. Thomas Goulding, of the Bank. 
Side, Southwark, to whom I owe it in justice to declare, that his 
work is executed with such truth and accuracy, as reflect the highest 
credit on his manufactory. 
* A pound of sugar from a gallon of raw liquor, is reckoned in 
Jamaica very good yielding. Sugar, chemically analysed, yields 
phlegm, acid, oil, and spongy glossy charcoal.
