When the liquor in the filter reaches the top and the char hassettled in a compact mass, the cover is put on and fastened se-curely to prevent leakage. The liquor is again allowed to runinto the filter by gravity, from the tanks about fifteen feet over-head. The valve on the bottom of the filter is then opened andthe liquor, as it filters slowly through the char, is led througha copper pipe to the liquor gallery, to which station all the char-.
