    In order that the system may be the more easily understood we have prepared plans, description, and estimates, which are based on the practical results hitherto obtained, for dealing with 100,000 gallons of sewage per day. They are approxi- mate, however, as the arrangement and cost depend to some extent upon local conditions; but we shall be pleased in all cases, on receiving full particulars, to prepare special plans and estimates. Description of Works for 100,000 Gallons of Sewage per day. The accompanying plans show the Patent Filters in connection with the ordinary precipitation tanks, sludge well, &c., with suitable connections. The sewage enters the works under the buildings, and on its way to the tanks receives the proper quantity of chemicals ; it then passes into the tanks, these being used in rotation so as to allow the solid matters precipitated from the sewage in the form of sludge to be cleaned out into the sludge pit. In passing through the tanks the matters in suspension are deposited, and the clear supernatant water flows on to the surface of the Filter through channels imbedded in the surface, and controlled by sluices in the end wall and partitions as shown. These are so arranged that any of the divisions can be shut off for cleaning the surface without interfering with the others or with the action of the main body of the Filter. The liquid passes downwards through the Filter and finds its way into the underdrains, which, with the air pipes, are shown by dotted lines on the plan, thence into the inspection well and so away by the effluent conduit in a thoroughly purified condition. Air is supplied to the Filter by the air pipe shown, which communicates with branch pipes laid in the body of the Filter. The blower for supplying the air is driven by the same engine that is used for mixing the chemicals and doing other work, consequently the cost of the additional power required is practically inappreciable.
