the shed into the main building, where it falls between the rollers, is crushed, and drops upon another carrier that conveys it out of the main building in an opposite direction, depositing it in the top of a chimney upon a fire beneath, which consumes it. It is necessary to burn it in this manner, because otherwise it would soon fill the building, and more especially because it would soon sour and engender disease. The juice of the cane falls into a conductor underneath the iron rollers, and is carried into a reservoir. Pipes convey it from thence into five filterers, holding several hogsheads each. These filterers are filled with bone-black, a substance resembling pulverized charcoal. It is made of bones calcinated in close vessels, and is used for the purpose of decolorizing, by filtration, the cane juice before boiling. Through these five filterers it passes in succession, and then runs into a large reservoir underneath the ground floor, from whence it is carried up, by means of a steam pump, into a clarifier made of sheet iron, where it is heated by steam until it boils. From the first clarifier it is carried in pipes to a second and a third, and thence into close iron pans, through which tubes pass, filled with steam. While in a boiling state it flows through three pans in succession, and is then carried in other pipes down to the coolers on the ground floor. Coolers are wooden boxes with sieve bottoms made of the finest wire. As soon as the syrup passes into the coolers, and is met by the air, it grains, and the molasses at once escapes through the sieves into a cistern
