    Ilughan's Improvements in Treating Sewage, 8fc, . . . I ■ —-—---W • -- ' ' ' ' ■ ' application of heat when rapidity of manufacture is essential. I some¬ times add other ingredients besides carbonate of magnesia into the dissolving tub along with the phosphates, and I sometimes add other manure ingredients, such as potash, for incorporation in the mortar mill when I want to manufacture special manures. The niglitsoil when not 5 used in the superphosphate manufacture must be treated to acid, and I would prefer the use of a carboy to a ton of nightsoil before being cemented up, otherwise it is dangerous, as protracting, overpowering, and sometimes destroying the cementatious principle. I sometimes use Portland cement, and this I prefer to use in the same manner as the 10 plaster of Paris or sulphate of lime, as herein-before described, in com¬ bination with the superpliosphated urinous or nightsoil mixture, some¬ times adding sulphate of magnesia and chloride of sodium. Portland cement I consider the best cementer of nightsoil alone, or in com¬ bination with phosphates, magnesia, and salt; but I occasionally use 15 other suitable cements upon consideration of price, locality, carriage, or otherwise.
