But the use of wind as a motive power does not seem to have occurred to the Cornish miners, or perhaps it was thought to be too uncertain to be of much value for pumping purposes.
It is possible enough that Savery had read the suggestions of the Marquess of Worcester, and that this ingenious author gave him the first hint whither to turn to find the force required. But how he was led to steam is differently stated.
Desaguliers says that Savery’s own account was this: Having drunk a flask of Florence at a tavern, and thrown the bottle into the fire, he proceeded to wash his hands, when he noticed that the little wine left in the flask was converted into steam. He took the vessel by the neck and plunged its mouth into the water in the basin, when, the steam being condensed, the water was immediately driven up into the bottle by the atmospheric pressure.
Switzer, however, who was very intimate with Savery, gives another account. He says that the first hint from which he took the engine was from a tobacco-pipe, which he immersed in water to wash or cool it. Then he noticed how that by the rarefaction of the air in the tube by the heat, the gravitation or pressure of the external air, upon the condensation of the steam, made the water to spring through the tube of the pipe in a most surprising manner.
However it was that Savery obtained his first idea of the expansion and condensation of steam and of atmospheric pressure, he had now before him a new and untried power with which to deal, and he was obliged to approach it by several tentative efforts.
Before 1696 he had constructed several steam pumping engines to mines in Cornwall, and he described these as already working in his book entitled The Miners’ Friend.[24 - Reprinted in the Journal of the Royal Institute of Cornwall, 1904.] He took with him a model to London and exhibited it to William III in 1698, and the King promoted Savery’s application for a patent, which was secured in July, 1698, and an Act was passed confirming it in the ensuing year.
Papin saw Savery’s steam engine, when exhibited before the Royal Society, he also witnessed the trial of his paddle-boat on the Thames. Returning to Marburg, of which university he was professor, he thought over what he had seen, and it occurred to him to combine the two contrivances in one, and to apply Savery’s motive power in the pump to drive Savery’s paddle-wheels. But it took him fifteen years to fit up a boat that worked to his satisfaction. “It is important,” he wrote to Liebnitz on 7 July, 1707, “that my new construction of vessel should be put to the proof in a seaport like London, where there is depth enough to apply the new invention, which, by means of fire, will render one or two men capable of producing more effect than some hundreds of rowers.” Papin’s boat that he intended to send to London was destroyed by some watermen, who feared the new invention might interfere with their trade.
Savery proposed to apply his engine to various purposes. One was to pump water into a reservoir for the production of an artificial waterfall for driving mills or any other ordinary machinery; that is to say, by means of steam he would lift a body of water which by flowing back might drive an overshot wheel, from the rotation of which the motive power for any other mechanical operations would be derived. This, however, was never done, and Savery’s engine continued to be employed only in the drainage of Cornish mines. But it had this disadvantage, that it could not heave water but to about eighty feet, and as the depth of mines was from fifty to a hundred yards, the only way to exhaust the water was by erecting several engines in successive stages, one above the other. But the expense of fuel and attendants and the constant danger of explosions rendered it clear that the use of his engine for deep mines was altogether impracticable. Such was the state of affairs when Thomas Newcomen, a blacksmith and ironmonger of Dartmouth, turned his attention to the matter.
Thomas Newcomen was a member of a very ancient family.
In the church of Stoke Fleming, near Dartmouth, is a brass with this inscription: —
Elias old lies here intombed in grave,
But Newcomin to heaven’s habitation.
In knowledge old, in zeal, in life most grave,
Too good for all who live in lamentation.
Whose sheep and seed with heavie plaint and mone,
Will say too late, Elias old is gone!
The 13th May, 1614.
Over this inscription is a shield of arms, with helmet, crest, and mantling, bearing the arms of Newcomen, of Saltfleetby, in Lincolnshire, with six quarterings. This is the monument of Elias Newcomen, rector of Stoke Fleming. The pedigree of the family commences with Hugo Newcomen, of Saltfleetby, in 1189–99. Elias Newcomen, rector of Stoke Fleming, had a brother Robert, who went to Ireland and was created a baronet.
The son of the Rev. Elias was Thomas, who settled in Dartmouth, and this Thomas had a son Elias, who was the father of the inventor Thomas, who was baptized at Dartmouth 28 February, 1663–4. He married Hannah, daughter of Peter Waymouth, of Malborough, Devon, in 1705, and died in 1729.
He left two sons, Thomas and Elias; and Thomas Newcomen, son of the inventor, compiled a pedigree with a view to proving his claim to the Irish baronetcy, but probably abandoned the attempt from want of funds to prosecute the claim.[25 - Worthy (C.), Devonshire Parishes, II, pp. 371–4. Exon., 1888.]

For some time Thomas Newcomen carried on his experiments in secret on the leads of his house. A letter extant of the time is quoted by Mr. Lidstone.
“When [Newcomen] was engaged on his great work, which took him three years from its commencement until it was completed, and was kept a profound secret, some of his friends would press Mrs. Newcomen to find out what her husband was engaged about, and, ‘for their part, they would not be satisfied to be kept in ignorance.’ Mrs. Newcomen replied, ‘I am perfectly easy. Mr. Newcomen cannot be employed about anything wrong; and I am fully persuaded, when he thinks proper, he will, himself, unasked, inform me.’”
When Thomas Newcomen had perfected his engine he associated with himself Calley or Cawley, a Dartmouth brazier, and How, another Dartmouth man, in applying for a patent.
Newcomen was a man of reading, and was in correspondence with Dr. Hooke, secretary of the Royal Society. There are to be found among Hooke’s papers, in the possession of the Royal Society, some notes of observations made by him for the use of Newcomen on Papin’s boasted method of transmitting to a great distance the action of a mill by means of pipes. Papin’s project was to employ the mill to work two air pumps of great diameter. The cylinders of these pumps were to communicate by means of pipes with equal cylinders furnished with pistons in the neighbourhood of a mine. The pistons were to be connected by means of levers with the piston-rods of the mine. Therefore, when the piston of the air pumps at the mill was drawn up by the engine the corresponding piston at the side of the mine would be pressed down by the atmosphere, and thus would raise the piston-rod in the mine and throw up the water. It would appear from these notes that Dr. Hooke dissuaded Newcomen from erecting a machine on this principle, of which he saw the fallacy.
It is highly probable that, in the course of his labours and speculations, it occurred to Newcomen that the vacuum he so much desired to create might be produced by steam, and that this gave rise to his new principle, and the construction of his steam engine. He saw the defects of Savery’s engine, and laboured to correct them. Savery, however, claimed the invention as his own, which lay at the root of Newcomen’s improvements; and Newcomen, being a Quaker, and averse from contention, and moreover glad to be assisted by Savery’s wide circle of acquaintances, was content to share the honours and the profits with Savery.
Switzer, who knew both, says: “Mr. Newcomen was as early in his invention as Mr. Savery was in his; only, the latter being nearer the Court, had obtained the patent before the other knew it, on which account Mr. Newcomen was glad to come in as a partner to it.”[26 - Switzer, Introduction to Hydrostatics and Hydraulics, p. 342.]

Savery had created his vacuum by the condensation of steam in a closed vessel by dashing cold water against it. Papin had created his vacuum by exhausting the air in a cylinder, fitted with a piston, by means of an air pump. What Newcomen did was to combine both systems. Instead of employing Savery’s closed vessel, he made use of Papin’s cylinder fitted with a piston, but worked by the condensation of steam, still employing the clumsy system of dashing cold water against the cylinder.
Whilst the engine was still in its trial state an accident occurred that led to another change in the mode of condensation. It was this. In order to keep the cylinder as free from air as possible, great pains were taken to prevent it from passing down with the piston, and to keep the cylinder air-tight, water was employed to lie above the place where the piston passed up or down.
At one of the early trials the inventors were surprised to see the engine make several rapid strokes, and on looking into the cause found that there was a small hole in the piston, which allowed a jet of cold water to penetrate within, and that this acted as a rapid condenser of the steam.
A new light suddenly broke upon Newcomen. The idea of condensing the steam, and so producing a vacuum by injecting cold water into the receiver, instead of splashing it against the outside, at once occurred to him; and he proceeded to embody the principle which this accident had suggested, as part of his machine.
Another improvement was due to another accident, if so it may be termed. To keep the machine in action a man or boy had to be employed in turning alternately two taps, one admitting the steam into the cylinder, the other admitting the cold jet into it to condense it.
The story has been often told how that a boy named Humphry Potter was planted beside the engine to turn the cocks, and found that this was excessively tedious and monotonous work, and being a shrewd lad, observing the alternate ascent and descent of the beam above his head, worked by the piston, he thought that by attaching to the beam the levers that governed the cocks, that would do the work for him. The result was the contrivance of what he called the scoggan, consisting of a catch, worked at first by strings, and afterwards by rods, that did the work automatically. This story has however been discredited. See Galloway’s Steam Engine, 1881.
“Thus, step by step,” says Mr. Smiles, “Newcomen’s engine grew in power and efficiency, and became more and more complete as a self-acting machine. It will be observed that, like all other inventions, it was not the product of any one man’s ingenuity, but of many. One contributed one improvement, and another another. The essential features of the atmospheric engine were not new. The piston and cylinder had been known as long ago as the time of Hero (222–205 B.C.). The expansive force of steam and the creation of a vacuum by its condensation had been known to the Marquess of Worcester, Savery, Papin, and many more.
“Newcomen merely combined in his machine the result of their varied experience, and, assisted by the persons who worked with him, down to the engine-boy Potter, he advanced the inventions several important stages, so that the steam-engine was no longer a toy or a scientific curiosity, but had become a powerful machine capable of doing useful work.”[27 - Smiles, Lives of Boulton and Watt, pp. 62–8. London, 1865.]
In 1712 Newcomen and his partner, Cawley, contracted to erect an engine at Wolverhampton. Next they erected two engines near Newcastle. The fourth was put up at Leeds in 1714. The fifth was erected in Cornwall at Wheal Fortune in 1720, and was on a larger scale than any previously constructed, having a cylinder of nearly four feet in diameter, and its performance was regarded as extraordinary, since it made fifteen strokes a minute, and drew up at each stroke a hogshead of water from a depth of 180 feet.
Thomas Savery was a captain of military engineers in 1702, and in 1705 he published a translation of Cohorn’s work on fortification. In the same year he was appointed Treasurer of the Hospital for Sick and Wounded Seamen. In 1714, by the favour of Prince George of Denmark, he was given the surveyorship to the waterworks at Hampton Court; but he died in the course of the following year, 15 May, 1715.
The date of Newcomen’s death has been already mentioned. Engines of his pattern continued to be erected long after his death, till there was scarcely a tin or copper mine of any importance in Cornwall that had not one or more of such engines at work, and the gaunt and ugly ruins of the engine-houses disfigure the landscape throughout the mining districts of Cornwall.
In 1882 Louis Figuier produced a five-act play at the Gaieté in Paris on Denis Papin. According to this version, Papin, who was a Huguenot, having fled to London with his family after the Revocation of the Edict of Nantes, abandoned wife and family to go to Germany, there to pursue his scientific investigations. When skimming a pot, he noticed the force that raised the lid, and conceived the idea of the power of steam.
He next set about contriving a model of a steamboat, and as that was successful, he constructed another on a large scale on the Weser, which was hacked to pieces by the boatmen, who were incited to this act of vandalism by a harpy of the name of Barbara. Papin returned to London, where his wife and son, he learned, had died during his ten years’ absence, and there, when reduced to the utmost distress, he learned that a Dartmouth locksmith named Thomas Newcomer [sic] had invented an engine in which steam was employed as a motive power. Papin then begged his way to Dartmouth, and recognized in Newcomer his son, whom he had supposed to be dead. The young man had been led to this invention by information he had found in drawings and writings of his father that had been left behind when he went to Germany. Papin did not make himself known, however, but allowed his son to reap all the honour and reward of his discovery. In the last scene Newcomer’s pump is being tried on the Thames in the presence of the Lord Mayor and Corporation of London, when Barbara and the Weser boatmen, having crossed the “silver streak” for the purpose, cripple the machine by cutting some cord that prevents the valve opening, and Papin, who has perceived this, rushes forward to avert an explosion, and falls a victim to his generous devotedness, for the boiler bursts just as he reaches it; he dies in his son’s arms, and Newcomer proclaims to the Lord Mayor and the world generally that all the honour of the invention and application of steam is due to his father, a Frenchman – a very satisfactory conclusion for a French audience.[28 - Pengelly (W.), “Notes on Slips,” in Transactions of the Devonshire Association, 1882.]
The French continue to claim for their countryman the glory of being the inventor of the modern steam engine. The system of the Marquess of Worcester was propulsion of cold water by the introduction of a blast of steam. Papin suggested the use of a vacuum formed by condensation of steam, so as to work a piston; and this vacuum in a cylinder he formed first by exploding gunpowder in it; and, as this did not answer, by removing the fire every time the condensation was required – a clumsy and impracticable method. Savery formed the vacuum first by dashing cold water against the cylinder, then by forming an outer ring of cold water about the receiver; but this did not answer well, as this body of water rapidly heated. Moreover, he did not adopt the piston, but drew up the water from mines by suction. Then came Newcomen, who adapted the piston in a cylinder to Savery’s engine; and finally Newcomen and Savery together discovered how to chill and condense the steam by an injection of cold water. Papin undoubtedly suggested the leading lines on which the steam engine was to be constructed, but he was unable effectually to apply his ideas or to rectify defects in such machines as he suggested. The solution was due to Newcomen and Savery.
ANDREW BRICE, PRINTER
Andrew Brice, an Exeter printer, was born 21 August, 1692, “in the house where Mary Hellier now lives [1719] near the Butcherow.”[29 - Entries in an old Bible, in the Western Antiquary, 1885, p. 196.] He was educated to be a dissenting minister, and received a good grounding in classical studies. But owing to the pinched circumstances of his father, and probably also his own disinclination for the pastorate, he was withdrawn from school, and at the age of seventeen apprenticed to a printer. His earliest biographer[30 - Universal Magazine for 1781.] states: —
“Mr. Bliss, a printer of Exeter, wanting a person capable of correcting the press, young Brice (aged 17) was proposed to, and accepted by him as an apprentice for the term of five years. However, having long before his service expired inconsiderately contracted marriage, and being unable to support a family of a wife and two children, he enlisted as a soldier in order to cancel his indentures; and, by the interest of his friends, very soon procured his discharge.” Bliss in his paper, the Mercury, 30 December, 1715, inserted this advertisement: “Whereas Andrew Brice, who is my Lawful Apprentice, hath, without any Cause, in the midst of a Flush of Business, and when I was disabled by Illness from working myself, roguishly absconded and deserted my Service to my present great Loss of Businress [sic], and Damage, this is to forbid all Persons to entertain or Employ the said Andrew Brice in any Business, or upon any Account, whatsoever; for, acting by the Advice of the Learned in the Law, I am resolved, upon Notice thereof to prosecute such as shall so do. If he returns not to my Business in a very short Time, I shall apply myself to the Magistrates of this City for Justice in this Case.
“N.B. I am inform’d his dependence is on Mr. Bishop; but I am greatly deceiv’d, if He is not a Person of more sense; and better understands what belongs to an Apprentice, than to encourage such a Rascal as shall so basely leave his Master without the least Cause. JOE BLISS.”
What became of Brice during the next two years is not known, but in 1717 he was back in Exeter, for on 22 March of that year Bliss inserted the following paragraph in his Protestant Mercury: “N.B. Having received reiterated Assurances from several Gentlemen, that, notwithstanding that Villain Brice’s Opposition against me, they are firmly resolved to continue in my Interest: To oblige them, therefore, and the rest of my Customers, I shall for the future publish my News on no worse Paper than this, Price One Penny. I can’t forbear remarking, how that sorry Rascal has opened his Printing Press with a most rediculous and shabby Advertisement, and a shameful obscene bawdy Ballad, which deserves to be burnt. Curious Specimens of Rare Genius and Great Capacity.”
It is evident from this that Brice had already taken up his permanent abode in Exeter, and had established himself there with a printing press of his own. His place of business was in Southgate Street, and he started a paper of his own, the Postmaster, or Loyal Mercury. In the “Journals of the House of Commons” we find under date 19 December, 1718: “Complaint having been made to the House, as a printed Pamphlet, intituled The Postmaster, or the Loyal Mercury, Friday, November the 28th, 1718; Exon. Printed by Andrew Brice, at the head of the Serge Market in Southgate Street. Wherein the Resolutions and Proceedings of this House are falsely represented and printed, in Contempt of the Order, and in Breach of the Privilege of this House; the said Pamphlet was delivered in at the Clerk’s Table; and several Paragraphs thereof being read: Ordered That the said Andrew Brice do attend this House upon Wednesday the 14th January.”
