After a lapse of more than a century and a half, Savery’s claim is not likely to be materially disturbed; but it will always be a matter of interest to observe the close similarity there is between the simple model he exhibited before the Royal Society, and the Marquis of Worcester’s brief summary of the parts and nature of his own engine. And it is not very favourable to a belief in Savery’s independence of the Marquis’s invention, that the former should be the sole inventor of a single marvellous production of ingenuity, without producing any novelty either before or afterwards, or displaying any particular inventive ability to improve on this early effort, which he left as at first produced. “The Miners Friend” is not unlike an imitation of the “Exact and true definition of the most Stupendous Water-commanding Engine;” for example:-- The MARQUIS’S invention is SAVERY recommends the Engine recommended “to every he proposes:-- individual, if he either have 4. “As for draining fens and surrounded Marsh-ground to marshes,” &c. drain, or dryland to improve.” “Thus whole cities may be kept 3. “Nothing can be more fit for clean, delightful, and serving cities and towns wholesome.” with water.” “Or, if he have (I further say), 6. “For draining of mines and coal Mines wherewith to enrich pits, the use of the engine himself withal.” will sufficiently recommend itself in raising water so easy and cheap.” “Houses to be served, or 2. “It may be of great use for gardens to be beautified by palaces, for the nobilities, plentiful fountains, with or gentlemen’s houses; for little charge, yet certain in by a cistern on the top of ever so dry a Summer.” a house * * * which water in its fall makes you what sorts of fountains you please.” Savery says:--“And though my thoughts have been long imployed about water-works, I should never have pretended to any invention of that kind, had I not happily found out this new, but yet a much stronger and cheaper force or cause of motion than any before made use of. But finding this of rarefaction by fire, the consideration of the difficulties the miners and colliers labour under by the frequent disorders, cumbersomness, and in general of water-engines, incouraged me to invent engines to work by this new force, that tho’ I was obliged to incounter the oddest and almost insuperable difficulties, I spared neither time, pains, nor money till I had absolutely conquer’d them.”
