    Geary's Improvements in the Preparation of Fuel. as the effervescence is apparent introduce the remainder of the small coal, stirring in order to blend the matters equally, and continue the stirring till the whole becomes well and equally heated, when the mixture may be permitted to run from the vessel into moulds, which should be of a quadrangular or other figure, 5 which will produce blocks of a shape to pack closely together when the same have been well dried. When the matter has been run into the moulds, and partly cooled, pressure or beating may be applied in order to compress the blocks into as small a space as possible, but this is not essential, though where stowage is material it is desirable that the blocks should each be well beaten 10 or pressed into the mould. Having thus explained the nature of the materials employed by me, and the manner of combining the same, and having been particular in stating quan¬ tities of the matters which I have found best to answer the purpose, I would have it understood that variations may be made without departing from my 15 Invention, which does not consist in the quantities of the matters employed, nor is it necessary, in all cases, to use one or more of the matters contained under secondly and thirdly, in a fuel, though I consider it better to do so. And I would have it understood that what I claim as my Invention is the mode of preparing fuel by combining small coal with melted pitch, and with other 20 matters when in a heated state, and causing the mixture to be acted on by acid, as above explained, but I do not claim the combining such materials when an acids is or are not employed. In witness whereof, I, the said Stephen Geary, have hereunto set my hand and seal, this Twenty-eighth day of November, One thousand 25 eight hundred and thirty-eight. STEPHEN (l.s.) GEARY.
