EAST ORANGE AND ITS POINTS OF INTEREST. 47 Water for dissolving the chemicals enters by a pipe from the town water mains. Air from a com-pressor is blown in at the bottom of the tank and the active agitation rapidly dissolves the outflow of chemicals to the sewage is regulated by a gate-valve. At present about grains of iimeand grains of sulphate of alunmia, are added per gallon of sewage treated. 1he sewage is highly di-luted with a large flow of ground water taken into the twenty-six miles of sewers in the town—more thantwelve miles of which are constructed in a saturated Railroad Place (Brick Church). The filter-press consists of thirty-six cast-iron cells, supported on a simple frame, with a centralfeed passage into which the sludge is forced from the receivers. The cells are separated by canvas bagsand in the intercellular spaces the sludge remains, while the water is strained out through the canvas mtoa trough on the rear of the press and returns to the tanks. On the end of the press is a capstan sere*connected with a throat-block which presses the thirty-six cells of the press into close contact. It ,s theair pressure which separates the water from the sludge. There is nothing offensive about these cakes when pressed dry ; and, it protected from wate,after being taken from the press, may be kept in bulk for weeks without nuisance. But, m the presenceof heat and moisture, they become more or less objectionable. As the sewage enter
