Savery’s next step was to bring his invention under the notice of the Royal Society, whose opinion on all matters of science was listened to with profound respect. He accordingly exhibited his model at a meeting held on the 14th of June, 1699, and it is recorded in the minutes of that date, that “Mr. Savery entertained the Society with showing his engine to raise water by the force of fire. He was thanked for showing the experiment, which succeeded according to expectation, and was approved of.” The inventor presented the Society with a drawing of his engine, accompanied by a description, which was printed in the ‘Transactions.’[30] [29] The patent is dated the 25th July, 1698, and is entitled, “A grant to Thomas Savery, Gentl., of the sole exercise of a new invenc̃on, by him invented, for raiseing of water, and occasioning moc̃on to all sort of mill works, by the impellant force of fire, which will be of great use for draining mines, serving towns with water, and for the working of all sorts of mills when they have not the benefit of water nor constant winds; to hold for 14 years; with usual clauses.” [30] ‘Philosophical Transactions,’ No. 252. Weld’s ‘Royal Society,’ i. 357. Savery next endeavoured to bring his invention into practical use, but this was a matter of much greater difficulty. So many schemes with a like object had been brought out and failed, that the mining interest came to regard new projects with increasing suspicion. To persuade them that he was no mere projector, but the inventor of a practicable working engine, Savery wrote and published his ‘Miner’s Friend.’ “I am not very fond,” he there said, “of lying under the scandal of a bare projector, and therefore present you here with a draught of my machine, and lay before you the uses of it, and leave it to your consideration whether it be worth your while to make use of it or no.”
