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 

 it is 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 in 

 every pond in India that is kept clear of weeds." — H.']
