PROVISIONAL SPECIFICATION left by John Thomas Darke at the Office of the Commissioners of Patents, with his Petition, on the 18th March 1869. I, John Thomas Dahke, of Oatlancls Park, in the Parish of Walton- 5 on-Thames, in the County of Surrey, clo hereby declare the nature of the said Invention for “ Treating Sewage and the Manufacture of Manure therefrom,” to be as follows :— The said Invention has for its object the separation of the solid and liquid sewage for the purpose of subsequent treatment, and consists in 10 receiving the sewage on a filtering fabric supported by a perforated surface, the fabric being adapted for arresting the more solid parts of sewage matter and allowing the liquid sewage to pass away through the perforations below the fabric. The sewage matter arrested by the filtering fabric is treated with dry earth or other deodorizing and dis- 15 infecting substance. The sewage matter so treated is removed from the perforated surface when in a dry or partially dry state and made into masses of any convenient size or form for carriage and use as manure
