346 
pots, with an aperture in the bottom. The water carries 
along with it the extractive, and the minute saccharine 
particles united with it, which constitute what is called 
treacle, and leaves behind the pure chrystalline sugar. In 
our West India Islands, the water is supplied by a cake of 
moist clay, placed on the surface of the sugar: but in India 
itis supplied by covering the upper surface with a layer of 
Vallisneria alternifolia.” Other aquatic weeds, indeed, are 
employed, but a preference seems to be given to the latter, 
. in consequence of its great abundance, as “ it grows im 
every pond in India that is kept clear of weeds." —H.]
