62 above
I adv 1. наверх, наверху; 2. выше Наречие above 2. носит книжный характер и употребляется главным образом в письменной речи. Оно используется для отсылки к уже упомянутому и чаще всего сочетается с глаголами сообщения типа mention, report, state, quote и с существительными типа table, paragraph:as shown (reported, stated) above — как показано (как сообщалось, как указывалось и т. д.) выше;
the table above shows — таблица, приведенная выше, показывает.
II prp 1. над; 2. свыше, выше, больше (1). Предлог above может употребляться с предшествующим указанием на расстояние до указанного объекта:far above our heads — высоко над нашей головой.
Такое одновременное указание на положение и расстояние часто связано с наречиями и предлогами along, behind, below, beyond, down, under, up:a few steps behind the crowd — пару шагов позади толпы;
a mile below — милей ниже;
far down — далеко внизу;
miles and miles along the shore — много миль вдоль берега.
(2). Предлог above подчеркивает нахождение объекта выше, чем что-либо, поднятым над некоторой точкой отсчета, и предполагает известное расстояние между этими двумя точками. Предлог above может относиться как к пространственному, физическому положению, так и к умственным способностям, духовным качествам и социальному положению:in a flat above the shop — в квартире над магазином;
six feet above the level of the floor — шесть футов над полом;
above sea-level — выше уровня моря, над уровнем моря;
two degrees above zero — два градуса выше нуля;
above your ability — выше твоих способностей;
above criticism — выше всякой критики.
(3). Русское над в значении положения над чем-либо, выше, чем что-либо, кроме предлога above, может передаваться предлогом over. Однако over, в отличие от above, не предполагает ни обязательного расстояния между двумя объектами, ни положения выше точки отсчета, а подчеркивает непосредственное полное или частичное покрытие всей поверхности:He held his hands above his head — Он держал руки вытянутыми над головой (он держал руки прямо вверх от плеч так, что они поднимались/были выше головы).
He held his hands over his head — Он закрывал/прикрывал голову руками (он держал руки, прикрывая голову полностью или частично).
В ряде контекстов предлоги above и over взаимозаменимы:He held an umbrella over/above her head — Он держал зонтик у нее над головой.
The aeroplane flew over/above the city — Самолет летел над городом.
(4). В количественных выражениях above 2., как и его антоним below, указывает только на направление и положение относительно точки отсчета:500 ft above sea level — 500 футов над уровнем моря;
children above the age of 10 (aged 10 and above) — дети около 10 лет.
В отличие от above, предлог over подчеркивает превышение степени качества, часто значительное, по сравнению с ожидаемой на некоторой шкале:He is over sixty (но не above) — Ему уже за шестьдесят (больше чем шестьдесят);
He has been there over five hours — Он пробыл там свыше (намного больше) пяти часов.
The repairs to my watch cost me over five pounds — Починка часов стоила мне более пяти фунтов.
(5). Для указания движения над чем-либо, поверх чего-либо и часто перемещения за пределы этого объекта употребляется только over:to throw the ball over the fence — перебросить мяч через забор;
to jump over the stream — перепрыгнуть через ручей;
to lean over the child — склониться/наклониться над ребенком.

Предлог above может употребляться с предшествующим указанием на расстояние до упомянутого объекта, обозначая, таким образом, одновременно и положение и расстояние по отношению к упомянутому объекту: far above our heads высоко над нашей головой. Такое одновременное указание на положение и расстояние присуще как предлогам, так и омонимичным им наречиям along, behind, below, beyond, down under, up: a few steps behind the crowd на несколько шагов позади толпы/в нескольких шагах позади толпы; a mile below милей ниже; far down далеко внизу; miles and miles along the shore много миль вдоль берега. (2.) Предлог above подчеркивает нахождение объекта выше, чем что-либо, поднятым над некоторой точкой отсчета, и предполагает некоторое расстояние между этими двумя точками. Предлог above может относиться как к пространственному, физическому положению: in a flat above the shop в квартире над магазином; six feet above the level of the floor шесть футов над полом; above sea-level выше уровня моря/над уровнем моря; two degrees above zero два градуса выше нуля; так и к интеллектуальным способностям, духовным качествам и социальному положению: above your ability выше твоих способностей; above criticism выше всякой критики. (3.) При указании точного количества above 2., как и его антоним below, указывает только на направление и положение относительно точки отсчета, а само расстояние обозначено точно числительным: 500 feet above sea level пятьсят футов над уровнем моря; children above the age of 10 (aged 10 and above) дети старше десяти лет. (4.) Для указания движения над чем-либо, поверх чего-либо и часто перемещения за пределы этого объекта употребляется только over а не above: to throw the ball over the fence перебросить мяч через забор; to jump over the stream перепрыгнуть через ручей; to lean over the child склониться/наклониться над ребенком. То же касается и значения "превышение количества": he is over sixty ему более шестидесяти/ему/за шестьдесят. (5.) Русский предлог "над" может передаваться английскими предлогами above и over. Их различие состоит в том, что above предполагает вертикальное расстояние над объектом, с которым нет соприкосновения, a over предполагает покрытие объекта, часто при соприкосновении с ним: the clouds above the house тучи над домом; the shard over the bed тень/тент над кроватью; the umbrella above/over the head зонтик над головой; he held his hands over his head он прикрыл голову руками; the aeroplane flew high above/over the city самолет летел над городом. В случае касания объекта предлог over переводится как "на": to spread a newspaper over the table расстелить газету на столе -

68 Bouch, Sir Thomas
SUBJECT AREA: Civil engineering[br]b. 22 February 1822 Thursby, Cumberland, Englandd. 1880 Moffat[br]English designer of the ill-fated Tay railway bridge.[br]The third son of a merchant sea captain, he was at first educated in the village school. At the age of 17 he was working under a Mr Larmer, a civil engineer, constructing the Lancaster and Carlisle railway. He later moved to be a resident engineer on the Stockton \& Darlington Railway, and from 1849 was Engineer and Manager of the Edinburgh \& Northern Railway. In this last position he became aware of the great inconvenience caused to traffic by the broad estuaries of the Tay and the Forth on the eastern side of Scotland. The railway later became the Edinburgh, Perth \& Dundee, and was then absorbed into the North British in 1854 when Bouch produced his first plans for a bridge across the Tay at an estimated cost of £200,000. A bill was passed for the building of the bridge in 1870. Prior to this, Bouch had built many bridges up to the Redheugh Viaduct, at Newcastle upon Tyne, which had two spans of 240 ft (73 m) and two of 260 ft (79 m). He had also set up in business on his own. He is said to have designed nearly 300 miles (480 km) of railway in the north, as well as a "floating railway" of steam ferries to carry trains across the Forth and the Tay. The Tay bridge, however, was his favourite project; he had hawked it for some twenty years before getting the go-ahead, and the foundation stone of the bridge was laid on 22 July 1871. The total length of the bridge was nearly two miles (3.2 km), while the shore-to-shore distance over the river was just over one mile (1.6 km). It consisted of eighty-five spans, thirteen of which, i.e. "the high girders", were some 245 ft (75 m) long and 100 ft (30 m) above water level to allow for shipping access to Perth, and was a structure of lattice girders on brick and masonry piers topped with ironwork. The first crossing of the bridge was made on 26 September 1877, and the official opening was on 31 May 1878. On Sunday 28 December 1879, at about 7.20 pm, in a wind of probably 90 mph (145 km/h), the thirteen "high girders" were blown into the river below, drowning the seventy-five passengers and crew aboard the 5.20 train from Burntisland. A Court of Enquiry was held and revealed design faults in that the effect of wind pressure had not been adequately taken into account, faults in manufacture in the plugging of flaws in the castings, and inadequate inspection and maintenance; all of these faults were attributed to Bouch, who had been knighted for the building of the bridge. He died at his house in Moffat four months after the enquiry.[br]Principal Honours and DistinctionsKnighted. Cross of St George.Further ReadingJohn Prebble, 1956, The High Girders.IMcN -
69 Brunel, Isambard Kingdom
SUBJECT AREA: Civil engineering, Land transport, Mechanical, pneumatic and hydraulic engineering, Ports and shipping, Public utilities, Railways and locomotives[br]b. 9 April 1806 Portsea, Hampshire, Englandd. 15 September 1859 18 Duke Street, St James's, London, England[br]English civil and mechanical engineer.[br]The son of Marc Isambard Brunel and Sophia Kingdom, he was educated at a private boarding-school in Hove. At the age of 14 he went to the College of Caen and then to the Lycée Henri-Quatre in Paris, after which he was apprenticed to Louis Breguet. In 1822 he returned from France and started working in his father's office, while spending much of his time at the works of Maudslay, Sons \& Field.From 1825 to 1828 he worked under his father on the construction of the latter's Thames Tunnel, occupying the position of Engineer-in-Charge, exhibiting great courage and presence of mind in the emergencies which occurred not infrequently. These culminated in January 1828 in the flooding of the tunnel and work was suspended for seven years. For the next five years the young engineer made abortive attempts to find a suitable outlet for his talents, but to little avail. Eventually, in 1831, his design for a suspension bridge over the River Avon at Clifton Gorge was accepted and he was appointed Engineer. (The bridge was eventually finished five years after Brunel's death, as a memorial to him, the delay being due to inadequate financing.) He next planned and supervised improvements to the Bristol docks. In March 1833 he was appointed Engineer of the Bristol Railway, later called the Great Western Railway. He immediately started to survey the route between London and Bristol that was completed by late August that year. On 5 July 1836 he married Mary Horsley and settled into 18 Duke Street, Westminster, London, where he also had his office. Work on the Bristol Railway started in 1836. The foundation stone of the Clifton Suspension Bridge was laid the same year. Whereas George Stephenson had based his standard railway gauge as 4 ft 8½ in (1.44 m), that or a similar gauge being usual for colliery wagonways in the Newcastle area, Brunel adopted the broader gauge of 7 ft (2.13 m). The first stretch of the line, from Paddington to Maidenhead, was opened to traffic on 4 June 1838, and the whole line from London to Bristol was opened in June 1841. The continuation of the line through to Exeter was completed and opened on 1 May 1844. The normal time for the 194-mile (312 km) run from Paddington to Exeter was 5 hours, at an average speed of 38.8 mph (62.4 km/h) including stops. The Great Western line included the Box Tunnel, the longest tunnel to that date at nearly two miles (3.2 km).Brunel was the engineer of most of the railways in the West Country, in South Wales and much of Southern Ireland. As railway networks developed, the frequent break of gauge became more of a problem and on 9 July 1845 a Royal Commission was appointed to look into it. In spite of comparative tests, run between Paddington-Didcot and Darlington-York, which showed in favour of Brunel's arrangement, the enquiry ruled in favour of the narrow gauge, 274 miles (441 km) of the former having been built against 1,901 miles (3,059 km) of the latter to that date. The Gauge Act of 1846 forbade the building of any further railways in Britain to any gauge other than 4 ft 8 1/2 in (1.44 m).The existence of long and severe gradients on the South Devon Railway led to Brunel's adoption of the atmospheric railway developed by Samuel Clegg and later by the Samuda brothers. In this a pipe of 9 in. (23 cm) or more in diameter was laid between the rails, along the top of which ran a continuous hinged flap of leather backed with iron. At intervals of about 3 miles (4.8 km) were pumping stations to exhaust the pipe. Much trouble was experienced with the flap valve and its lubrication—freezing of the leather in winter, the lubricant being sucked into the pipe or eaten by rats at other times—and the experiment was abandoned at considerable cost.Brunel is to be remembered for his two great West Country tubular bridges, the Chepstow and the Tamar Bridge at Saltash, with the latter opened in May 1859, having two main spans of 465 ft (142 m) and a central pier extending 80 ft (24 m) below high water mark and allowing 100 ft (30 m) of headroom above the same. His timber viaducts throughout Devon and Cornwall became a feature of the landscape. The line was extended ultimately to Penzance.As early as 1835 Brunel had the idea of extending the line westwards across the Atlantic from Bristol to New York by means of a steamship. In 1836 building commenced and the hull left Bristol in July 1837 for fitting out at Wapping. On 31 March 1838 the ship left again for Bristol but the boiler lagging caught fire and Brunel was injured in the subsequent confusion. On 8 April the ship set sail for New York (under steam), its rival, the 703-ton Sirius, having left four days earlier. The 1,340-ton Great Western arrived only a few hours after the Sirius. The hull was of wood, and was copper-sheathed. In 1838 Brunel planned a larger ship, some 3,000 tons, the Great Britain, which was to have an iron hull.The Great Britain was screwdriven and was launched on 19 July 1843,289 ft (88 m) long by 51 ft (15.5 m) at its widest. The ship's first voyage, from Liverpool to New York, began on 26 August 1845. In 1846 it ran aground in Dundrum Bay, County Down, and was later sold for use on the Australian run, on which it sailed no fewer than thirty-two times in twenty-three years, also serving as a troop-ship in the Crimean War. During this war, Brunel designed a 1,000-bed hospital which was shipped out to Renkioi ready for assembly and complete with shower-baths and vapour-baths with printed instructions on how to use them, beds and bedding and water closets with a supply of toilet paper! Brunel's last, largest and most extravagantly conceived ship was the Great Leviathan, eventually named The Great Eastern, which had a double-skinned iron hull, together with both paddles and screw propeller. Brunel designed the ship to carry sufficient coal for the round trip to Australia without refuelling, thus saving the need for and the cost of bunkering, as there were then few bunkering ports throughout the world. The ship's construction was started by John Scott Russell in his yard at Millwall on the Thames, but the building was completed by Brunel due to Russell's bankruptcy in 1856. The hull of the huge vessel was laid down so as to be launched sideways into the river and then to be floated on the tide. Brunel's plan for hydraulic launching gear had been turned down by the directors on the grounds of cost, an economy that proved false in the event. The sideways launch with over 4,000 tons of hydraulic power together with steam winches and floating tugs on the river took over two months, from 3 November 1857 until 13 January 1858. The ship was 680 ft (207 m) long, 83 ft (25 m) beam and 58 ft (18 m) deep; the screw was 24 ft (7.3 m) in diameter and paddles 60 ft (18.3 m) in diameter. Its displacement was 32,000 tons (32,500 tonnes).The strain of overwork and the huge responsibilities that lay on Brunel began to tell. He was diagnosed as suffering from Bright's disease, or nephritis, and spent the winter travelling in the Mediterranean and Egypt, returning to England in May 1859. On 5 September he suffered a stroke which left him partially paralysed, and he died ten days later at his Duke Street home.[br]Further ReadingL.T.C.Rolt, 1957, Isambard Kingdom Brunel, London: Longmans Green.

[br]b. 17 December 1797 Albany, New York, USAd. 13 May 1878 Washington, DC, USA[br]American scientist after whom the unit of inductance is named.[br]Sent to stay with relatives at the age of 6 because of the illness of his father, when the latter died in 1811 Henry was apprenticed to a silversmith and then turned to the stage. Whilst he was ill himself, a book on science fired his interest and he began studying at Albany Academy, working as a tutor to finance his studies. Initially intending to pursue medicine, he then spent some time as a surveyor before becoming Professor of Mathematics and Natural Philosophy at Albany Academy in 1826. There he became interested in the improvement of electromagnets and discovered that the use of an increased number of turns of wire round the core greatly increased their power; by 1831 he was able to supply to Yale a magnet capable of lifting almost a ton weight. During this time he also discovered the principles of magnetic induction and self-inductance. In the same year he made, but did not patent, a cable telegraph system capable of working over a distance of 1 mile (1.6 km). It was at this time, too, that he found that adiabatic expansion of gases led to their sudden cooling, thus paving the way for the development of refrigerators. For this he was recommended for, but never received, the Copley Medal of the Royal Society. Five years later he became Professor of Natural Philosophy at New Jersey College (later Princeton University), where he deduced the laws governing the operation of transformers and observed that changes in magnetic flux induced electric currents in conductors. Later he also observed that spark discharges caused electrical effects at a distance. He therefore came close to the discovery of radio waves. In 1836 he was granted a year's leave of absence and travelled to Europe, where he was able to meet Michael Faraday. It was with his help that in 1844 Samuel Morse set up the first patented electric telegraph, but, sadly, the latter seems to have reaped all the credit and financial rewards. In 1846 he became the first secretary of the Washington Smithsonian Institute and did much to develop government support for scientific research. As a result of his efforts some 500 telegraph stations across the country were equipped with meteorological equipment to supply weather information by telegraph to a central location, a facility that eventually became the US National Weather Bureau. From 1852 he was a member of the Lighthouse Board, contributing to improvements in lighting and sound warning systems and becoming its chairman in 1871. During the Civil War he was a technical advisor to President Lincoln. He was a founder of the National Academy of Science and served as its President for eleven years.[br]Principal Honours and DistinctionsPresident, American Association for the Advancement of Science 1849.

71 Jessop, William
[br]b. 23 January 1745 Plymouth, Englandd. 18 November 1814[br]English engineer engaged in river, canal and dock construction.[br]William Jessop inherited from his father a natural ability in engineering, and because of his father's association with John Smeaton in the construction of Eddystone Lighthouse he was accepted by Smeaton as a pupil in 1759 at the age of 14. Smeaton was so impressed with his ability that Jessop was retained as an assistant after completion of his pupilage in 1767. As such he carried out field-work, making surveys on his own, but in 1772 he was recommended to the Aire and Calder Committee as an independent engineer and his first personally prepared report was made on the Haddlesey Cut, Selby Canal. It was in this report that he gave his first evidence before a Parliamentary Committee. He later became Resident Engineer on the Selby Canal, and soon after he was elected to the Smeatonian Society of Engineers, of which he later became Secretary for twenty years. Meanwhile he accompanied Smeaton to Ireland to advise on the Grand Canal, ultimately becoming Consulting Engineer until 1802, and was responsible for Ringsend Docks, which connected the canal to the Liffey and were opened in 1796. From 1783 to 1787 he advised on improvements to the River Trent, and his ability was so recognized that it made his reputation. From then on he was consulted on the Cromford Canal (1789–93), the Leicester Navigation (1791–4) and the Grantham Canal (1793–7); at the same time he was Chief Engineer of the Grand Junction Canal from 1793 to 1797 and then Consulting Engineer until 1805. He also engineered the Barnsley and Rochdale Canals. In fact, there were few canals during this period on which he was not consulted. It has now been established that Jessop carried the responsibility for the Pont-Cysyllte Aqueduct in Wales and also prepared the estimates for the Caledonian Canal in 1804. In 1792 he became a partner in the Butterley ironworks and thus became interested in railways. He proposed the Surrey Iron Railway in 1799 and prepared for the estimates; the line was built and opened in 1805. He was also the Engineer for the 10 mile (16 km) long Kilmarnock \& Troon Railway, the Act for which was obtained in 1808 and was the first Act for a public railway in Scotland. Jessop's advice was sought on drainage works between 1785 and 1802 in the lowlands of the Isle of Axholme, Holderness, the Norfolk Marshlands, and the Axe and Brue area of the Somerset Levels. He was also consulted on harbour and dock improvements. These included Hull (1793), Portsmouth (1796), Folkestone (1806) and Sunderland (1807), but his greatest dock works were the West India Docks in London and the Floating Harbour at Bristol. He was Consulting Engineer to the City of London Corporation from 1796to 1799, drawing up plans for docks on the Isle of Dogs in 1796; in February 1800 he was appointed Engineer, and three years later, in September 1803, he was appointed Engineer to the Bristol Floating Harbour. Jessop was regarded as the leading civil engineer in the country from 1785 until 1806. He died following a stroke in 1814.[br]Further ReadingC.Hadfield and A.W.Skempton, 1979, William Jessop.

72 Morland, Sir Samuel
SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering[br]b. 1625 Sulhampton, near Reading, Berkshire, Englandd. 26 December 1695 Hammersmith, near London, England[br]English mathematician and inventor.[br]Morland was one of several sons of the Revd Thomas Morland and was probably initially educated by his father. He went to Winchester School from 1639 to 1644 and then to Magdalene College, Cambridge, where he graduated BA in 1648 and MA in 1652. He was appointed a tutor there in 1650. In 1653 he went to Sweden in the ambassadorial staff of Bulstrode Whitelocke and remained there until 1654. In that year he was appointed Clerk to Mr Secretary Thurloe, and in 1655 he was accredited by Oliver Cromwell to the Duke of Savoy to appeal for the Waldenses. In 1657 he married Susanne de Milleville of Boissy, France, with whom he had three children. In 1660 he went over to the Royalists, meeting King Charles at Breda, Holland. On 20 May, the King knighted him, creating him baron, for revealing a conspiracy against the king's life. He was also granted a pension of£500 per year. In 1661, at the age of 36, he decided to devote himself to mathematics and invention. He devised a mechanical calculator, probably based on the pattern of Blaise Pascal, for adding and subtracting: this was followed in 1666 by one for multiplying and other functions. A Perpetual Calendar or Almanack followed; he toyed with the idea of a "gunpowder engine" for raising water; he developed a range of speaking trum-pets, said to have a range of 1/2 to 1 mile (0.8–1.6 km) or more; also iron stoves for use on board ships, and improvements to barometers.By 1675 he had started selling a range of pumps for private houses, for mines or deep wells, for ships, for emptying ponds or draining low ground as well as to quench fire or wet the sails of ships. The pumps cost from £5 to £63, and the great novelty was that he used, instead of packing around the cylinder sealing against the bore of the cylinder, a neck-gland or seal around the outside diameter of the piston or piston-rod. This revolutionary step avoided the necessity of accurately boring the cylinder, replacing it with the need to machine accurately the outside diameter of the piston or rod, a much easier operation. Twenty-seven variations of size and materials were included in his schedule of'Pumps or Water Engines of Isaac Thompson of Great Russel Street', the maker of Morland's design. In 1681 the King made him "Magister mechanicorum", or Master of Machines. In that year he sailed for France to advise Louis XIV on the waterworks being built at Marly to supply the Palace of Versailles. About this time he had shown King Charles plans for a pumping engine "worked by fire alone". He petitioned for a patent for this, but did not pursue the matter.In 1692 he went blind. In all, he married five times. While working for Cromwell he became an expert in ciphers, in opening sealed letters and in their rapid copying.[br]Principal Honours and DistinctionsKnighted 1660.Bibliography1685, Elevation des eaux.Further ReadingH.W.Dickinson, 1970, Sir Samuel Morland: Diplomat and Inventor, Cambridge: Newcomen Society/Heffers.IMcN -
73 Smeaton, John
SUBJECT AREA: Civil engineering, Mechanical, pneumatic and hydraulic engineering, Steam and internal combustion engines[br]b. 8 June 1724 Austhorpe, near Leeds, Yorkshire, Englandd. 28 October 1792 Austhorpe, near Leeds, Yorkshire, England[br]English mechanical and civil engineer.[br]As a boy, Smeaton showed mechanical ability, making for himself a number of tools and models. This practical skill was backed by a sound education, probably at Leeds Grammar School. At the age of 16 he entered his father's office; he seemed set to follow his father's profession in the law. In 1742 he went to London to continue his legal studies, but he preferred instead, with his father's reluctant permission, to set up as a scientific instrument maker and dealer and opened a shop of his own in 1748. About this time he began attending meetings of the Royal Society and presented several papers on instruments and mechanical subjects, being elected a Fellow in 1753. His interests were turning towards engineering but were informed by scientific principles grounded in careful and accurate observation.In 1755 the second Eddystone lighthouse, on a reef some 14 miles (23 km) off the English coast at Plymouth, was destroyed by fire. The President of the Royal Society was consulted as to a suitable engineer to undertake the task of constructing a new one, and he unhesitatingly suggested Smeaton. Work began in 1756 and was completed in three years to produce the first great wave-swept stone lighthouse. It was constructed of Portland stone blocks, shaped and pegged both together and to the base rock, and bonded by hydraulic cement, scientifically developed by Smeaton. It withstood the storms of the English Channel for over a century, but by 1876 erosion of the rock had weakened the structure and a replacement had to be built. The upper portion of Smeaton's lighthouse was re-erected on a suitable base on Plymouth Hoe, leaving the original base portion on the reef as a memorial to the engineer.The Eddystone lighthouse made Smeaton's reputation and from then on he was constantly in demand as a consultant in all kinds of engineering projects. He carried out a number himself, notably the 38 mile (61 km) long Forth and Clyde canal with thirty-nine locks, begun in 1768 but for financial reasons not completed until 1790. In 1774 he took charge of the Ramsgate Harbour works.On the mechanical side, Smeaton undertook a systematic study of water-and windmills, to determine the design and construction to achieve the greatest power output. This work issued forth as the paper "An experimental enquiry concerning the natural powers of water and wind to turn mills" and exerted a considerable influence on mill design during the early part of the Industrial Revolution. Between 1753 and 1790 Smeaton constructed no fewer than forty-four mills.Meanwhile, in 1756 he had returned to Austhorpe, which continued to be his home base for the rest of his life. In 1767, as a result of the disappointing performance of an engine he had been involved with at New River Head, Islington, London, Smeaton began his important study of the steam-engine. Smeaton was the first to apply scientific principles to the steam-engine and achieved the most notable improvements in its efficiency since its invention by Newcomen, until its radical overhaul by James Watt. To compare the performance of engines quantitatively, he introduced the concept of "duty", i.e. the weight of water that could be raised 1 ft (30 cm) while burning one bushel (84 lb or 38 kg) of coal. The first engine to embody his improvements was erected at Long Benton colliery in Northumberland in 1772, with a duty of 9.45 million pounds, compared to the best figure obtained previously of 7.44 million pounds. One source of heat loss he attributed to inaccurate boring of the cylinder, which he was able to improve through his close association with Carron Ironworks near Falkirk, Scotland.[br]Principal Honours and DistinctionsFRS 1753.Bibliography1759, "An experimental enquiry concerning the natural powers of water and wind to turn mills", Philosophical Transactions of the Royal Society.Towards the end of his life, Smeaton intended to write accounts of his many works but only completed A Narrative of the Eddystone Lighthouse, 1791, London.Further ReadingS.Smiles, 1874, Lives of the Engineers: Smeaton and Rennie, London.
