    Mohuns Improvements in Manufacturing Fuel. linseed with the rosin and nitre are to be crushed very fine by edge stones or other means, and the green vegetable matter is also to be ground or crushed in like manner, and thus produce a pulp, taking care to keep the vegetable juices from running away. The whole of the materials are then to be mixed with spades 5 or otherwise well ground in the pug mill, the object being to obtain an intimate blending of the various materials in order to the same burning equally. The combined mass thus so produced is then to be pressed in moulds by a strong screw or other press, the shape and dimensions of the lumps not being material, but it is desirable the materials should be well pressed in 10 order to prevent the lumps readily coming to pieces ; if well pressed the fuel will be apt to crumble and burn too fast if exposed to a strong draft, but I claim the combination whether the same be submitted to pressure or not, the advantage of pressing being to encrease the time it takes consuming. The lumps thus produced are to be piled one on the other, leaving spaces between 15 for the circulation of the atmosphere. And it will facilitate the preparation to have such piles in a closed shed or room, the atmosphere of which can be heated, though in summer time and in warm dry weather this will not be necessary, unless great expedition is required. Care must be taken not to expose it to a great artificial heat when just formed or pressed. It must be 20 dried by the atmosphere only for the first two or three days. Note,—the peat it should be observed may be first used for the purposes of distilling gas therefrom, as has been before practised, and the charred peat in the retorts subsequently used for the making of the fuel in place of the raw peat as above described. And in order to make the new fuel for the purpose of 25 obtaining gas therefrom for illuminating purposes take in the proportion of ten pounds of nitre, forty pounds of rosin, twenty-four pounds of linseed, one hundredweight of green vegetable matter, one ton of peat, which being combined and treated according to the directions above given, and the lumps put into ordinary gas retorts, and distilled similar to ordinary coal. 30 Having thus described the nature of my Invention and the manner of combining the same, I would remark that I do not confine myself to the precise three processes here described, for it will be evident that the object to be obtained is a careful combining or mixing of the materials herein mentioned, and the subsequent pressing the same into hard lumps, of con- 35 venient size; and whether such processes are conducted as above described, or by any other convenient means, it does not alter the nature of my Invention. And I would remark, that I do not claim the application of each of the eight parts or materials separately as a fuel, whether pressed or unpressed, some of them, such as the peat earths or peat turf, peat moss, and coke, and some
