    De Fontainemoreau s Improvements in the Manufacture of Fuel. can be sunk into the ground either in part or in whole, but in that case it is necessary to cut an inclined road reaching its basis, and the door D to enable the workman to have free access to it. The furnace can also be constructed by means of a sufficient hole dug in the ground, surrounding the side with a 5 brick wall, taking care in that case also to have a proper road reaching the door D, as herein-before stated. The furnace being constructed by any of the means herein-before described, the operations for carbonising is conducted as follows:—Twenty or twenty-five bundles of small branches of trees or any other kind of ligneous substances 10 are thrown into the furnace through the opening at the top C, and the fire is applied to them by the aperture D, set at the lower part of the furnace, when the woody substances are well lighted ; the door D is shut air tight, and well luted to prevent internally any introduction of the external air, and another quantity of alimenting substances is thrown again into the furnace by the said 15 opening at the top, through which the smoke escapes; the same mode of feeding the furnace is carried on during the whole time the carbonising takes place, which allows the furnace to be filled with vegetable charcoal to nearly three-fourths of its height. The opening C is then shut with a sheet iron damper, or any other suitable contrivance, and the bottom door D opened, in 20 order to withdraw with an iron raker the charcoal from the furnace. The charcoal is immediately extinguished either by sprinkling water over it with a watering pot, or by throwing it into convenient close vessels, in which it is immediately extinguished, or again by covering it with a thick layer of charcoal perfectly cold. 25 As soon as the charcoal contained in the furnace has been withdrawn, as herein-before described, the door D is shut and well luted again, and the furnace is fed with bundles or any other ligneous substances in order to repeat the former operations, without however, being obliged, then and for all the following ones if they are carried successively one after the other, to put on 30 fire the woody substances contained in the furnace, as the caloric retained by it is quite sufficient for carbonising without producing the smallest incinerations. Pulverization of the Carbonised Substances. _ The substances being carbonized, as herein-before described, are sub¬ mitted to the pulverizing apparatus represented by Drawing 11, Figure 1, 35 which is a plan of the machine. In that Figure A is a circular cast-iron through, having about nine feet in diameter and one foot in heighth ; B is a vertical shaft giving the motion to the cylinders serving to pound the carbonized
