This tree presents in the interval between its outer bark of sap-wood, a mass of fibrous matter about half an inch in thickness, richly impregnated with mucilage, which is obtained by macerating the fibrous mass, conveniently divided into small shreds, for about twelve hours, in warm water, in the proportion of about two handsful to eight gallons of water. Of this solution, which is of a light, straw color, and somewhat thickened, one gallon is to be added for every hundred gallons of cane juice, after the clarifier has been charged with the proper quantity of lime-water, and has become lukewarm. The mixture should then be stirred, and afterwards allowed to settle till the scum has risen to the surface. The fire must next be cautiously and gradually raised to the point of boiling, when it must again be slackened, and the whole left to stand for about forty minutes, by which time the mass of feculencies will have risen to the surface, when the clear liquor underneath may either be drawn off by a siphon or cock; the whole may be filtered as Mr. Fownes recommends, by which means the liquor would be more effectually clarified, and much, if not all, the subsequent labour of skimming dispensed with. The matter remaining on the filter may be employed, either as a ferment in the still-house, or added to the manure heap. Much of the beneficial effect of the mucilage of the _guazuma_ arises probably from an admixture of tannin, or some other astringent; for I have often been struck with the peculiar whiteness of the potted sugar in the curing-house, in the immediate vicinity of the Banana stalks, resulting, no doubt, from their powerful astringency; and tannin has already been found useful in the manufacture of sugar from beet-root in France, and is no doubt equally applicable to cane-sugar. The liquor, when clarified in the manner described, must be concentrated, by regulated evaporation, to the degree requisite for crystallisation. This Mr. Fownes advises to be done by steam of a moderate pressure circulating in a spiral of copper-pipe laid at the bottom of the evaporating vessels, which should be large and shallow, and wholly unlike those in present use. Here it may be rapidly boiled down till the heat rises to about 225 deg., without risk of burning. When cold, it should have a density of about 1.38, and mark the 38th degree of Baume's hydrometer; beyond which point of inspissation it would be dangerous to go. The remaining concentration will be most safely conducted in the vacuum pan, where a scarcity of water does not, as in Barbados, militate against its use.
