    Stephens' Improvements in Treating Excreta, 8fC. Figure 9 represents an apparatus for preparing and making peat fuel, which apparatus is also applicable to the manufacture of manure, with a slight modification in the Barker’s mill fan combined used in making manure. A, A, is a cylinder turning on the pivots p, p, 5 to which there can he placed a covered top T6, T6, fastened water¬ tight by clamps to the cylinder A, A. To the top is affixed a forcing pump P1 which condenses the water in the cylinder, causing a great hydraulic pressure on the peat and soddens it, which at once destroys the fibrous and elastic properties in the peat, which peat may be 10 saturated with tar water or clay water, or other mixture, as may be deemed most expedient. When the peat has been submitted to this hydraulic pressure the peat and tar water can be emptied into the cylinder, described with reference to Figure 1, where the water can be readily separated from the peat, and in its fall will turn the Barker’s 15 mill and fan combined, which by the current of air produced will assist in drying the peat. The air in this case will be drawn from the top of the box B1, B1, it having no air communication with the lower box B, B. In the plan Figure 10 the Barker’s mill revolves in the box B, B, 20 without a corrugated circle, the water escaping by the pipe p1. The tube T, T, is attached to the hose H, H, which is attached to the filtering cylinder A, A, A. The fan draws the air from above at a, a, and drives it in the direction a1, a1, in a circle to dry the peat bricks. The air at a} a9 can be supplied by a pipe from the outer air if desired. 25 The apparatus for packing the manure in sacks is thus constructed :— Into the sack S1, S1, Figure 12, is placed some charcoal (fresh) at the bottom. Then the outer cylinder A2, and then inside of .that the cylinder A1, into which is placed the manure. Then between them is placed a layer of fresh charcoal or any other absorbent. The space between 30 them is kept evenly all round by the guards g, g. The cylinders can then be taken out, and the sack is packed with manure. What I claim as new in the treatment and manufacture of manure from the foecal matter of towns and other populous places are,— Firstly. Quick filtering by atmospheric pressure by an apparatus that 35 can easily be put into action after each discharge of the foecal matter and from a cylinder, substantially as set forth and shown.
