Molasses (Fr. Melasse), the sirup which remains in the manufacture of brown sugar, after separating from the juice all the saccharine matter that can be made to crystallize to advantage; also the inspissated juice of sorghum and sap of the maple. "Sugar-house " molasses is the sirup which remains in the conversion of brown into refined sugar, and which contains too little cane sugar to repay its further treatment. By fermentation and distillation molasses mixed with the skimmings of the sugar boiling is made to produce rum. (See Sugar.) The entire amount of molasses produced in the United States in 1870, according to the census, was 6,593,323 gallons of cane, of which 4,585,150 gallons were the product of Louisiana, 16,050,089 of sorghum, and 921,057 of maple. The production of cane molasses is limited to the southern states, while the cultivation of sorghum is general throughout the country. During the year ending June 30, 1873, 43,533,909 gallons of molasses, valued at $9,901,051, were imported into the United States, chiefly from Cuba.
