THl granite state evaporator and arch. sap runs from the storage tank into the evaporator at one end through an automaticregulator, and then flows across the pan, backwards and forwards several times, aroundthe end of the partitions, until it reaches the outlet at the finishing end, by which timeit is reduced to syrup of the desired density. The regulator, which is connected withthe storage tank by a rubber hose, increases or diminishes the inflow of sap according* Manufactured by the Granite State Evaporator Company, Albany, N. Y.

Bythis ingenious device there can be no scorching of the contents so long as there isplenty of sap in the storage tank. The continuous flow of the cold, raw sap into the evaporator keeps the liquid inthat end at a much lower temperature than the contents at the further end. As thestream flows from side to side in passing around or through the ends of the numerouspartitions the temperature increases, and the crude* liquid, by the time it reaches theoutlet, is ready to sugar off. The steaming, boiling fluid is skimmed carefully ofthe impurities which arise to the surface during its progress through the first compart-ments, and the shallow stream, with its broad surface exposed to the direct actionof
