    Manning's Improvements in Treating Foecal Matters. this mode of heating the bottom of my said evaporating chamber it will be more advantageous and economical in every respect to utilize the carburetted hydrogen gas so charged with atmospheric air as a heating power, by introducing and burning the same as a gaseous fuel under and along the sides of the said evaporating chamber, or 5 wherever it may be found advisable so to do. The said mixture of carburetted hydrogen gas and air so obtained may obviously be applied to other manufactures as a means of heating where large quantities of coal are consumed. In my said former Specification I stated that during the process of 10 evaporating the solid and fluid portion of the excretae to dryness I intro¬ duced a jet of steam into the chamber; but instead of simply admitting one or more jets of steam into the chamber at the commencement and near the end of the operation, after the greater portion (say 75 or 80 per cent.) of the water is evaporated, I now propose to admit the steam into 15 the hollow shaft of the agitator, on the under side of which small perforations are made, so that by the to-and-fro motion of such agitator it will disseminate the said steam on either side, thereby effectually preventing injury to the agitator and fan, until shortly after the com¬ mencement of the operation, when vapor will arise in sufficient force to 20 attain that object, whereupon the steam is turned off, as it is also at the end of the process when the sediment is reduced to dryness. Fig. 1 of the accompanying Drawings is a sectional elevation of an apparatus constructed according to my Invention, and Fig. 2 is a transverse section of the same. 25 The evaporating vessels a (which I have shewn as made of cast iron) are each constructed with a removeable door b9 and provided with a hollow rocking agitator shaft c, perforated at its under side, and workir g in suitable bearings. Through one of the bearings of each shaft steam may be admitted into the shaft by a pipe, as shewn at d, regulated by a 30 suitable cock or tap. The evaporating vessels a are set in brickwork e, the parts exposed to the heat being fire-brick, and the brickwork is formed at one end with a bridge a1, and a furnace or fire-place a2 to each of the said vessels, the brickwork being continued in the form of an arched roof over each of the vessels a, so as to enclose a sort of flue 35 space g above it, into which flue space hang suitable baffles /’suspended to the roof. At the opposite end to the furnace or fire-place, each flue space g communicates with an exhausting and forcing fan h> suitably
