    Parsons' Improvements in the Manufacture of Fuel, <§c. round, or encased in such composition. The composition to be employed for the coating may be the same as that already described as the inflammable cementing mixture, or with the addition of two pounds of plaster of Paris to every eight gallons of the inflammable cementing mixture. This composition being kept at a boiling point, the compact masses or blocks of fuel, formed as 5 just described, are dipped into it by means of a culinder or frame of bars, and being so dipped are withdrawn as quickly as possible and thrown upon a table or inclined plane thickly strewed with sawdust, a screen or sieve above shedding sawdust on these masses, so that they may become thoroughly coated on all sides with the sawdust before the hot inflammable composition has become set. By 10 this process the fuel is surrounded by a stong water-tight casing. The saw¬ dust adds to the strength of the casing of the inflammable composition, affords protection to the fuel, and prevents adhesion in the stowage, and obviates the wasting of the materials by the running of the resin or similar substance during the combustion of the fuel. Instead of sawdust, bran, pollard, or fine 15 chaff may be employed for the purpose of the above-mentioned casing. It will be evident, that the materials employed for the purposes aforesaid and their proportions may be very much varied, without departing from the peculiar features of my Invention, and I would observe that the coal, coal and sawdust, or other materials constituting the basis of the artificial fuel and the 20 component parts of the inflammable cementing composition, may be mixed together cold and then heated to such a temperature as will insure the thorough admixture of all the substances, and the coherence of the particles of the coal, coal and sawdust, or other materials when formed into cakes after pressure, as above described. I would also observe that it is only necessary to 25 use so much of the inflammable cementing composition as will occasion the eoherence of the particles of the coal, coal and sawdust, or other materials constituting the basis of the artificial fuel. The quantity necessary for this purpose will vary with the materials employed, as the basis of the fuel consists of artificial fuel; and where no coal is employed I add a larger quantity of 30 the cementing composition, as about seven quarts instead of six to each bushel of the material or mixture of materials constituting the basis of the fuel. The artificial fuel herein-before described, particularly that containing the largest quantity of resinous matter, is peculiarly applicable to the manu¬ facture of gas, in addition to the various other purposes for which artificial 35 fuel may be so advantageously employed. The casing of an inflammable cement, protected by sawdust or other sub¬ stance, as above described, may also be applied with great advantage to pieces of coal, coke, and wood, as such fuel will thus be rendered waterproof, and
