    Stuart’s Improvements in Treating and Utilizing Sewage. or nearly pure condition either into a river or for any use for which it may be found suitable. My system comprises the employing of a single main intercepting sewer or channel to convey the contents of a group of city sewers to a suburban establishment, whereat the separating and utilising processes 5 are to be conducted. And in order that my said Invention, and the manner of performing the same may be properly understood, I have hereunto appended a Sheet of explanatory Diagrams to be herein-after referred to, and indicating the main features of my improved arrangements and apparatus. 10 Figures 1 and 2 are Diagrams corresponding to sections taken at right angles to each other of a portion of the works at such a suburban establishment as has been herein-before referred to. The main channel or intercepting sewer 1 supplies the sewage to one or more large reservoirs 2, and through such reservoir to numerous 15 depositing tanks 3; the arrangement and construction of which mainly constitute my present Invention. The sewage first enters the large reservoir 1, which is formed with a deepened channel or race 4 along the side opposite to the inlet gratings; or sets of vertical rails 5, 6, are fitted along the sides of this race 4 to keep back floating and bulky articles. 20 In the race 4 there is an agitator, shown separately in plan in Figure 3, and in side elevation in Figure 4, and which is made somewhat in the form of a shuttle. This agitator shuttle is made to reciprocate from end to end of the race 4 by means of cords passing over pulleys, or by means of a simple connecting rod 7 actuated by means of a water 25 wheel 8 driven by the sewage current itself as it falls into the reservoir 2 from the main sewer 1, ducts 9 being adapted to the end of the sewer to direct the current upon the water wheel. The shaft of the water wheel 8 is arranged to drive a pair of inclined shafts 10, 11, by bevil wheels, and an eccentric on one of these inclined shafts actuates 30 a lever 12 to which the shuttle connecting rod 7 is jointed. The ends of the race 4 are to be inclined upwards (although this is not shown in the Diagrams) ; this inclination being for the purpose of carrying them above the level of the water, so that matters intercepted by the shuttle may be thrown out of the reservoir. The shuttle is in the form of a 35 double-ended scoop with bottom and sides shaped to fit the race. The two ends are hinged to a vertical partition piece in the middle, to which the connecting rod 7 is jointed. When the shuttle comes to either end
