A plan and descripti[on] of Mr. John Stewart'[s] fire engine mill, being a machine to apply the power of fire engines to all kinds of mills that require much force, but is most profitable to grind sugar canes; as one of them, with a Cylinder of Thirty Inches Diameter, is proved will do as much as four Cattle Mills, that employ from 160 to 200 Steers; and the Trash of the Canes, that works the Fire Engine, boils the great Coppers at the same Time, without any additional Expence, or Consumption of Fuel. And A Plan and Description of the Application of a Fire Engine to work Saws, that will be next most profitable to saw Timber, as the Slabs, or Branches of the Trees sawed, will supply Fuel without Expence, particularly in North America, as they may be set in the most convenient Situation for Timber and Navigation, &c. Also A Plan and Description of a Reservoir, to be made of Earth, that will be as staunch as Cisterns made of Stone and Lime, and grouted, and a Method of collecting Rain Water to supply them, as is practised in the East-Indies, and other Countries subject to long Drought. Likewise, a Plan and Description of a Sliding Rod, that, by the Fire Engine, which grinds the Canes, will work a Pump at a Distance of 400 Yards or upwards, from the Engine, and raise Water, that may be conveyed in Wooden Gutters, set on Posts or Phlars of Stone, to any higher Ground, that may be convenient to let into Cane Pieces to water Canes. Also a Description of Marles, such as used in most Parts in the North of England, to manure Land which the Patentee hath seen of the same Kinds in Parts in Jamaica, but it is not known to be Marle; or the Value of it, or the Uses and Benefits to be had by it. A further Description of the said Machines &c. is given in the Preface. With an Account of the Opposition and Distress the Patentee met in Jamaica, by Means of a Millwright, who imposed on the greater Part of the principle Gentlemen of the Island, by shewing them a Draught of a Counterfeit of the Patentee's Invention, that had two Wheels less and comparing it with a Draught of the Patentee's that was published, to believe it to be more useful, altho' it will herein appear, that it was an imaginary Invention, and that the said, Millwright used every diabolical Means, he could contrive, to depreciate and hinder the Patentee's Invention from coming into Practice.
