SUGAR. 21 
off as the liquor boils. After undergoing a similar 
process in smaller boilers, with a further mixture of 
lime, until it has attained a certain degree of thickness, 
it is transferred into a large shallow wooden vessel, 
where, as it cools, it granulates or runs into an imper- 
fect crystallization, by which it is in some degree se- 
parated from the molasses or treacle, an impure part of 
the juice, which is incapable of being crystallized, and 
which, in large casks, is exported, for various useful 
purposes, to the different countries of Europe. 
From the cooler the sugar is removed to the curing- 
house. This is a large, airy building, furnished with a 
capacious cistern, for the reception of the molasses. 
Over the cistern is an open frame of strong joist- work ; 
upon which are placed several empty hogsheads, each 
open at the head, and having a few holes at the bottom, 
closed by stalks of the plantain tree thrust through 
them. The mass of saccharine matter is now put into 
these hogsheads ; the molasses are separated from the 
sugar, by draining, into the cistern, through the spongy 
stalks of the plantain ; and the remainder, thus en- 
tirely crystallized, has the name of muscovado or raiv 
sugar. 
The article denominated clayed sugar undergoes a 
process somewhat different. For the preparation of 
this, the sugar, when taken from the coolers, is put 
into conical vessels of earthen-ware, each having, at 
its bottom, a hole, about half an inch in diameter, 
which, at the commencement of the process, is stopped 
with a plug. This plug, after the sugar has become 
perfectly cool, is removed, and the molasses drain 
through the hole. When these have ceased to run, the 
surface of the sugar, in the vessel, is covered with fine 
clay, to a certain thickness, and water is poured upon 
the clay. This, oozing through it, pervades the whole 
mass of sugar, re-dissolves the molasses still remaining 
in it, with some parts of the sugar itself, carries these 
off through the .hole at the bottom, and renders the
