101-531: The third son of Robert Vetch of Caponflat, Haddington, East Lothian , and his wife Agnes Sharp, he was born at Haddington on 13 May 1789. Educated at Haddington and Edinburgh, he entered the Royal Military College, Great Marlow , and in 1805 was transferred to the Royal Military Academy, Woolwich . He was employed on the trigonometrical survey at Oakingham , Berkshire (1806), until he received

202-585: A market town . Today, Haddington is a small town with a population of about 10,000 people, but during the High Middle Ages it was the fourth-biggest town in Scotland (after Aberdeen , Roxburgh and Edinburgh). In the middle of the town is the Haddington Town House , completed in 1745 based on a plan by William Adam . When first built, it contained markets on the ground floor, and an assembly hall on

303-514: A bar, expelling slag in the process. During the Middle Ages , water-power was applied to the process, probably initially for powering bellows, and only later to hammers for forging the blooms. However, while it is certain that water-power was used, the details remain uncertain. That was the culmination of the direct process of ironmaking. It survived in Spain and southern France as Catalan Forges to

404-582: A carbon content of less than 0.008 wt% . Bar iron is a generic term sometimes used to distinguish it from cast iron. It is the equivalent of an ingot of cast metal, in a convenient form for handling, storage, shipping and further working into a finished product. The bars were the usual product of the finery forge , but not necessarily made by that process: Wrought iron is a form of commercial iron containing less than 0.10% of carbon, less than 0.25% of impurities total of sulfur, phosphorus, silicon and manganese, and less than 2% slag by weight. Wrought iron

505-471: A commission as second lieutenant in the Royal Engineers on 1 July 1807. He was promoted to lieutenant on 1 March 1808. After serving for three years, partly at Chatham and partly at Plymouth, he was sent in 1810 to Spain, and joined the division of Sir Thomas Graham at the blockade of Cadiz . He took part in the battle of Barrosa on 5 March 1811, and was made the bearer of despatches to Gibraltar. Vetch

606-460: A double track. Passengers from Haddington were required to alight at Longniddry and change trains in order to travel to Edinburgh. The Haddington branch line and station were damaged during the flood of 1948 and though both passenger and freight services were reinstated, British Rail opted to remove rail services to the public due to competition from bus services and dwindling passenger numbers. Passenger services ended on 29 December 1949. The use of

707-470: A final product. Sometimes European ironworks would skip the shingling process completely and roll the puddle balls. The only drawback to that is that the edges of the rough bars were not as well compressed. When the rough bar was reheated, the edges might separate and be lost into the furnace. The bloom was passed through rollers and to produce bars. The bars of wrought iron were of poor quality, called muck bars or puddle bars. To improve their quality,

808-559: A hardware shop, cookware shop and several gift shops alongside several pubs, restaurants and cafés. Nationwide retailers with a presence in Haddington include: Tesco , Home Bargains , Boots , Aldi and Co-op Food . Besides retail and administration, the town is also home to various law firms and has industrial capacity in the works beside the Tyne at the Victoria Bridge (PureMalt), and around

909-463: A high silky luster and fibrous appearance. Wrought iron lacks the carbon content necessary for hardening through heat treatment , but in areas where steel was uncommon or unknown, tools were sometimes cold-worked (hence cold iron ) to harden them. An advantage of its low carbon content is its excellent weldability. Furthermore, sheet wrought iron cannot bend as much as steel sheet metal when cold worked. Wrought iron can be melted and cast; however,

1010-681: A large tract of country. His papers and maps on the subject were presented after his death to the topographical department of the War Office . He presented a collection of Mexican antiquities to the British Museum and wrote a paper about them. From 1839 the project of a ship canal between the Mediterranean and Red Seas occupied Vetch's attention. In 1843 he published a work on it which ran through several editions and attracted much public attention. The government, and especially Lord Palmerston , opposed

1111-434: A low scale to supply the steel to the artisan swordmakers. Osmond iron consisted of balls of wrought iron, produced by melting pig iron and catching the droplets on a staff, which was spun in front of a blast of air so as to expose as much of it as possible to the air and oxidise its carbon content. The resultant ball was often forged into bar iron in a hammer mill. In the 15th century, the blast furnace spread into what

1212-449: A lower melting point than iron or steel. Cast and especially pig iron have excess slag which must be at least partially removed to produce quality wrought iron. At foundries it was common to blend scrap wrought iron with cast iron to improve the physical properties of castings. For several years after the introduction of Bessemer and open hearth steel, there were different opinions as to what differentiated iron from steel; some believed it

1313-459: A modest amount of wrought iron was refined into steel , which was used mainly to produce swords , cutlery , chisels , axes , and other edged tools, as well as springs and files. The demand for wrought iron reached its peak in the 1860s, being in high demand for ironclad warships and railway use. However, as properties such as brittleness of mild steel improved with better ferrous metallurgy and as steel became less costly to make thanks to

1414-554: A number of notable buildings but the Abbey of St Mary and 16th Century town defences have left little to see on the ground. They are being researched by Haddington's History Society. St Martin's Kirk also remains one of the towns oldest and most prominent buildings. Amisfield House was located east of Haddington, south of the River Tyne. Designed by architect Isaac Ware and built of Garvald red freestone for Colonel Francis Charteris , it

1515-589: A number of patented processes for that, which are referred to today as potting and stamping . The earliest were developed by John Wood of Wednesbury and his brother Charles Wood of Low Mill at Egremont , patented in 1763. Another was developed for the Coalbrookdale Company by the Cranage brothers . Another important one was that of John Wright and Joseph Jesson of West Bromwich . A number of processes for making wrought iron without charcoal were devised as

1616-410: A process for manufacturing wrought iron quickly and economically. It involved taking molten steel from a Bessemer converter and pouring it into cooler liquid slag. The temperature of the steel is about 1500 °C and the liquid slag is maintained at approximately 1200 °C. The molten steel contains a large amount of dissolved gases so when the liquid steel hit the cooler surfaces of the liquid slag

1717-574: A publication now in the public domain :  Lee, Sidney , ed. (1899). " Vetch, James ". Dictionary of National Biography . Vol. 58. London: Smith, Elder & Co. Haddington, East Lothian The Royal Burgh of Haddington ( Scots : Haidintoun , Scottish Gaelic : Baile Adainn ) is a town in East Lothian , Scotland. It is the main administrative, cultural and geographical centre for East Lothian. It lies about 17 miles (27 kilometres) east of Edinburgh . The name Haddington

1818-410: A refinery where raw coal was used to remove silicon and convert carbon within the raw material, found in the form of graphite, to a combination with iron called cementite. In the fully developed process (of Hall), this metal was placed into the hearth of the puddling furnace where it was melted. The hearth was lined with oxidizing agents such as haematite and iron oxide. The mixture was subjected to

1919-481: A single hearth for all stages. The introduction of coke for use in the blast furnace by Abraham Darby in 1709 (or perhaps others a little earlier) initially had little effect on wrought iron production. Only in the 1750s was coke pig iron used on any significant scale as the feedstock of finery forges. However, charcoal continued to be the fuel for the finery. From the late 1750s, ironmasters began to develop processes for making bar iron without charcoal. There were

2020-412: A strong current of air and stirred with long bars, called puddling bars or rabbles, through working doors. The air, the stirring, and the "boiling" action of the metal helped the oxidizing agents to oxidize the impurities and carbon out of the pig iron. As the impurities oxidize, they formed a molten slag or drifted off as gas, while the remaining iron solidified into spongy wrought iron that floated to

2121-432: A very low carbon content (less than 0.05%) in contrast to that of cast iron (2.1% to 4.5%). It is a semi-fused mass of iron with fibrous slag inclusions (up to 2% by weight), which give it a wood-like "grain" that is visible when it is etched, rusted, or bent to failure . Wrought iron is tough, malleable, ductile , corrosion resistant, and easily forge welded , but is more difficult to weld electrically. Before

2222-424: Is redshort or hot short if it contains sulfur in excess quantity. It has sufficient tenacity when cold, but cracks when bent or finished at a red heat. Hot short iron was considered unmarketable. Cold short iron, also known as coldshear , colshire , contains excessive phosphorus. It is very brittle when cold and cracks if bent. It may, however, be worked at high temperature. Historically, coldshort iron

2323-478: Is Anglo-Saxon , dating from the sixth or seventh century AD when the area was incorporated into the kingdom of Bernicia . The town, like the rest of the Lothian region, was ceded by King Edgar of England and became part of Scotland in the tenth century. Haddington received Burgh status, one of the earliest to do so, during the reign of David I (1124–1153), giving it trading rights which encouraged its growth into

2424-484: Is a mainly fourteenth-century castle about 5 miles (8 kilometres) east of Haddington. This castle, which has a fine riverside setting, belonged to the Hepburn family during the most important centuries of its existence. Since 1926, it has been the subject of a state-sponsored guardianship agreement, which is now under the auspices of Historic Scotland. It is open to the public without charge at all reasonable times. Haddington

2525-414: Is a more important measure of the quality of wrought iron. In tensile testing, the best irons are able to undergo considerable elongation before failure. Higher tensile wrought iron is brittle. Because of the large number of boiler explosions on steamboats in the early 1800s, the U.S. Congress passed legislation in 1830 which approved funds for correcting the problem. The treasury awarded a $ 1500 contract to

2626-513: Is an archaic past participle of the verb "to work", and so "wrought iron" literally means "worked iron". Wrought iron is a general term for the commodity, but is also used more specifically for finished iron goods, as manufactured by a blacksmith . It was used in that narrower sense in British Customs records, such manufactured iron was subject to a higher rate of duty than what might be called "unwrought" iron. Cast iron , unlike wrought iron,

2727-435: Is brittle and cannot be worked either hot or cold. In the 17th, 18th, and 19th centuries, wrought iron went by a wide variety of terms according to its form, origin, or quality. While the bloomery process produced wrought iron directly from ore, cast iron or pig iron were the starting materials used in the finery forge and puddling furnace . Pig iron and cast iron have higher carbon content than wrought iron, but have

2828-491: Is deceptive. Most of the manganese, sulfur, phosphorus, and silicon in the wrought iron are incorporated into the slag fibers, making wrought iron purer than plain carbon steel. Amongst its other properties, wrought iron becomes soft at red heat and can be easily forged and forge welded . It can be used to form temporary magnets , but it cannot be magnetized permanently, and is ductile , malleable , and tough . For most purposes, ductility rather than tensile strength

2929-467: Is highly refined, with a small amount of silicate slag forged out into fibers. It comprises around 99.4% iron by mass. The presence of slag can be beneficial for blacksmithing operations, such as forge welding, since the silicate inclusions act as a flux and give the material its unique, fibrous structure. The silicate filaments in the slag also protect the iron from corrosion and diminish the effect of fatigue caused by shock and vibration. Historically,

3030-649: Is home to East Lothian Amateur Boxing Club, the East of Scotland football club Haddington Athletic , Haddington cricket club who are in east of Scotland division 3 and Haddington RFC , currently playing in Scotland Premiership division 3. At the end of March 2012, the town's library relocated to the John Gray Centre in Lodge Street, an extensively reconstructed and restored complex of historic buildings including

3131-407: Is no longer manufactured commercially. Wrought iron was originally produced by a variety of smelting processes, all described today as "bloomeries". Different forms of bloomery were used at different places and times. The bloomery was charged with charcoal and iron ore and then lit. Air was blown in through a tuyere to heat the bloomery to a temperature somewhat below the melting point of iron. In

3232-450: Is no longer produced on a commercial scale. Many products described as wrought iron, such as guard rails , garden furniture , and gates are made of mild steel. They are described as "wrought iron" only because they have been made to resemble objects which in the past were wrought (worked) by hand by a blacksmith (although many decorative iron objects, including fences and gates, were often cast rather than wrought). The word "wrought"

3333-615: Is now Belgium where it was improved. From there, it spread via the Pays de Bray on the boundary of Normandy and then to the Weald in England. With it, the finery forge spread. Those remelted the pig iron and (in effect) burnt out the carbon, producing a bloom, which was then forged into bar iron. If rod iron was required, a slitting mill was used. The finery process existed in two slightly different forms. In Great Britain, France, and parts of Sweden, only

3434-454: Is owned by East Lothian Council and is used by walkers, cyclists and horse-riders in the section of the line between Longniddry station and the St Lawrence area of Haddington. The eastern terminus of the line is occupied by industrial units and scrub vegetation. A campaign to reopen Haddington's railway service is led by the group RAGES (Rail Action Group East of Scotland). Since the closure of

These buses facilitate travel to Edinburgh , Berwick-upon-Tweed , and several other towns and villages in East Lothian . Since the withdrawal of many First Scotland East services in June 2012, the contracts for the 121 Haddington to North Berwick and

3737-550: The Bessemer process and the Siemens–Martin process , the use of wrought iron declined. Many items, before they came to be made of mild steel , were produced from wrought iron, including rivets , nails , wire , chains , rails , railway couplings , water and steam pipes , nuts , bolts , horseshoes , handrails , wagon tires, straps for timber roof trusses , and ornamental ironwork , among many other things. Wrought iron

3838-472: The Industrial Revolution began during the latter half of the 18th century. The most successful of those was puddling, using a puddling furnace (a variety of the reverberatory furnace ), which was invented by Henry Cort in 1784. It was later improved by others including Joseph Hall , who was the first to add iron oxide to the charge. In that type of furnace, the metal does not come into contact with

3939-673: The Real del Monte silver mines, associated with John Taylor , and those of Bolaños companies. He also gave his services to the Anglo-Mexican Mining Association, promoted by John Diston Powles and later to the United-Mexico Mining Association, a rival. He returned to England in 1829, but again went to Mexico after his marriage in 1832, and remained there until 1835. During his period in Mexico he constructed roads for

4040-595: The Walloon process was used. That employed two different hearths, a finery hearth for finishing the iron and a chafery hearth for reheating it in the course of drawing the bloom out into a bar. The finery always burnt charcoal, but the chafery could be fired with mineral coal , since its impurities would not harm the iron when it was in the solid state. On the other hand, the German process, used in Germany, Russia, and most of Sweden used

4141-517: The bloomery ever being used in China. The fining process involved liquifying cast iron in a fining hearth and removing carbon from the molten cast iron through oxidation . Wagner writes that in addition to the Han dynasty hearths believed to be fining hearths, there is also pictorial evidence of the fining hearth from a Shandong tomb mural dated 1st to 2nd century AD, as well as a hint of written evidence in

For his services in the Peninsula he received the war medal with clasps for Barrosa and Badajos. From 1814 to 1820 Vetch commanded a company of sappers and miners, first at Spike Island in Cork Harbour , where he was employed on

4444-589: The 123 Gifford Circle passed back to the Haddington-based firm Prentice Coaches. The nearest rail station is at Drem, four miles (six kilometres) to the north, which is served by regular Edinburgh to North Berwick trains. Haddington was once served by its own railway branch line which carried passengers for over a century from 1846 to 1949. There have been proposals to reopen or extend a railway line to Haddington to ease road congestion, but nothing has come to fruition in regards to this. The Haddington railway line

4545-680: The 1960s, the price of steel production was dropping due to recycling, and even using the Aston process, wrought iron production was labor-intensive. It has been estimated that the production of wrought iron is approximately twice as expensive as that of low-carbon steel. In the United States, the last plant closed in 1969. The last in the world was the Atlas Forge of Thomas Walmsley and Sons in Bolton , Great Britain, which closed in 1973. Its 1860s-era equipment

4646-418: The 4th century AD Daoist text Taiping Jing . Wrought iron has been used for many centuries, and is the "iron" that is referred to throughout Western history. The other form of iron, cast iron , was in use in China since ancient times but was not introduced into Western Europe until the 15th century; even then, due to its brittleness, it could be used for only a limited number of purposes. Throughout much of

Johnson and Benjamin Reeves conducted strength tests on boiler iron using a tester they had built in 1832 based on a design by Lagerhjelm in Sweden. Because of misunderstandings about tensile strength and ductility, their work did little to reduce failures. The importance of ductility was recognized by some very early in

4848-536: The Middle Ages, iron was produced by the direct reduction of ore in manually operated bloomeries , although water power had begun to be employed by 1104. The raw material produced by all indirect processes is pig iron. It has a high carbon content and as a consequence, it is brittle and cannot be used to make hardware. The osmond process was the first of the indirect processes, developed by 1203, but bloomery production continued in many places. The process depended on

4949-539: The River Tyne, beside the twelfth century Nungate Bridge. The present building (built with red sandstone from nearby Garvald ) was started in 1375 (an earlier St Mary's Church having been destroyed by the English in 1356), and consecrated in 1410, despite building work not being finished until 1487. The church was partially destroyed during the 1548-49 Siege of Haddington that followed the Rough Wooing of Henry VIII , and on

5050-530: The advice of John Knox , it was restored "frae the tower to the West door". Thus the nave became the church and the choir and transepts were left ruined until the whole church was restored in the 1970s. The Lammermuir pipe organ was built in 1990. A set of eight bells hung for full change ringing was installed for the Millennium . Haddington War Memorial stands at the west entrance to the churchyard. Hailes Castle

5151-451: The bars were cut up, piled and tied together by wires, a process known as faggoting or piling. They were then reheated to a welding state, forge welded, and rolled again into bars. The process could be repeated several times to produce wrought iron of desired quality. Wrought iron that has been rolled multiple times is called merchant bar or merchant iron. The advantage of puddling was that it used coal, not charcoal as fuel. However, that

In 1821 he was appointed to the ordnance survey, and during this and the two following years, assisted by his friends Thomas Drummond and Robert Kearsley Dawson , both of the Royal Engineers, he carried out the triangulation of the Orkney and Shetland islands and of the western islands of Scotland. Promotion being slow, Vetch retired on half-pay on 11 March 1824. He went to Mexico , and managed

5353-530: The construction of one half of its line. In 1842 Vetch designed a system of sewerage for the borough of Leeds , which was carried out. In 1843 he was associated with Sir Henry Thomas de la Beche in designs for the drainage of Windsor , and in 1844 designed drainage for Windsor Castle and parks and for the purification of the Frogmore lakes; these works were completed in 1847. After the Duchy of Cornwall Act 1844 , Vetch

This building occupies the site of Haddington's twelfth century royal palace and adjoins the former Sheriff Court complex . The town centre is home to a wide range of independent retailers including: a bookshop, a sports shop, a saddlery and country goods specialist, two butchers,

5555-413: The course of the smelt, slag would melt and run out, and carbon monoxide from the charcoal would reduce the ore to iron, which formed a spongy mass (called a "bloom") containing iron and also molten silicate minerals (slag) from the ore. The iron remained in the solid state. If the bloomery were allowed to become hot enough to melt the iron, carbon would dissolve into it and form pig or cast iron, but that

5656-468: The demolition of Bothwell Castle and its dovecote in 1955, the land now forming part of Hardgate Park. Today the whole town centre is a conservation area with a high proportion of listed buildings, some dating back to the C16th, and the redevelopment and infill schemes undertaken since the 1950s have largely been in a sympathetic vernacular style which has maintained the town's historic character. The town has

5757-498: The development of effective methods of steelmaking and the availability of large quantities of steel, wrought iron was the most common form of malleable iron. It was given the name wrought because it was hammered, rolled, or otherwise worked while hot enough to expel molten slag. The modern functional equivalent of wrought iron is mild steel , also called low-carbon steel. Neither wrought iron nor mild steel contain enough carbon to be hardened by heating and quenching. Wrought iron

5858-580: The development of the blast furnace, of which medieval examples have been discovered at Lapphyttan , Sweden and in Germany . The bloomery and osmond processes were gradually replaced from the 15th century by finery processes, of which there were two versions, the German and Walloon. They were in turn replaced from the late 18th century by puddling , with certain variants such as the Swedish Lancashire process . Those, too, are now obsolete, and wrought iron

Other notable nearby sites include: the Jane Welsh Carlyle House; Mitchell's Close; and a building on the High Street that was the birthplace of the author and government reformer Samuel Smiles and is marked by a commemorative plaque. John Knox

6060-432: The fuel, and so is not contaminated by its impurities. The heat of the combustion products passes over the surface of the puddle and the roof of the furnace reverberates (reflects) the heat onto the metal puddle on the fire bridge of the furnace. Unless the raw material used is white cast iron, the pig iron or other raw product of the puddling first had to be refined into refined iron , or finers metal. That would be done in

6161-401: The gases were liberated. The molten steel then froze to yield a spongy mass having a temperature of about 1370 °C. The spongy mass would then be finished by being shingled and rolled as described under puddling (above). Three to four tons could be converted per batch with the method. Steel began to replace iron for railroad rails as soon as the Bessemer process for its manufacture

Antique music wire , manufactured at a time when mass-produced carbon-steels were available, was found to have low carbon and high phosphorus; iron with high phosphorus content, normally causing brittleness when worked cold, was easily drawn into music wires. Although at the time phosphorus was not an easily identified component of iron, it

The Compass School, an independent fee-paying primary school and nursery, is located on the West Road. Historically, the Burgh schools mostly had a good reputation, an exception being under Rev. William Whyte who retained his office despite reports of violence and even death due to his brutal discipline. Thomas Donaldson

Sir Henry Ward , the British envoy, in an official report, called attention to his services. He was elected Fellow of the Royal Society in 1830; previously, in 1818, he had been elected to the Geological Society . Vetch was resident engineer of the Birmingham and Gloucester Railway Company from 1836 to 1840 for

6666-496: The old St Mary's RC Primary School in early-2009, the pupils temporarily attended makeshift classrooms at King's Meadow Primary School until the building was deemed safe again around mid-2009. In April 2011, East Lothian Council decided to build an entirely new school, because both schools would still be left with major problems even after substantial upgrades. A third primary school started construction at Letham Mains in April 2019, to serve

6767-451: The original open triangular medieval market place, divided by a central island of buildings developed from the 16th century onwards on the site of market stalls. To the north and south the medieval rigg pattern of burgage plots can still be observed with narrow buildings fronting the main streets and long plots behind stretching back, originally to the line of the old town walls, accessed by small closes and pends . The historic importance of

6868-579: The parish of Haddington was drawn up by the Rev. Dr. Barclay, and published by the Society of Scottish Antiquaries in 1785. James Miller published Lamp of Lothian a history of Haddington in 1844. A new edition was reprinted in 1900 under the name Lamp of Lothian: or, the history of Haddington, in connection with the Public Affairs of East Lothian and of Scotland, from the earliest records to 1844 . A goat appears on

6969-737: The plan as contrary to Britain's political interests. Twelve years later Ferdinand de Lesseps published his scheme, printing Vetch's opinions as an appendix to his work. Vetch married, on 2 February 1832 in London, Alexandrina Ogilvie (d. 1853), daughter of Robert Auld of Edinburgh. They had ten children, of whom seven survived him, including Rev. James Edward (d. 1870), Robert Hamilton, C.B. , colonel royal engineers, and William Francis, C.V.O., major-general, formerly Royal Dublin Fusiliers . Vetch's portrait, by Joshua Munro, went to his eldest surviving son. [REDACTED]  This article incorporates text from

7070-666: The product is no longer wrought iron, since the slag stringers characteristic of wrought iron disappear on melting, so the product resembles impure, cast, Bessemer steel. There is no engineering advantage to melting and casting wrought iron, as compared to using cast iron or steel, both of which are cheaper. Due to the variations in iron ore origin and iron manufacture, wrought iron can be inferior or superior in corrosion resistance, compared to other iron alloys. There are many mechanisms behind its corrosion resistance. Chilton and Evans found that nickel enrichment bands reduce corrosion. They also found that in puddled, forged, and piled iron,

7171-413: The railway line for freight continued until March 1968. The larger Victorian station building was demolished; a smaller older building, parts of the platform structure, and embankment walls remain. These are recognisable by their distinctive red-brick appearance, and can be seen from West Road, Somnerfield Court, and the industrial area south of Hospital Road. The land occupied by Haddington's railway line

7272-531: The same manner as mild steel, but the presence of oxide or inclusions will give defective results. The material has a rough surface, so it can hold platings and coatings better than smooth steel. For instance, a galvanic zinc finish applied to wrought iron is approximately 25–40% thicker than the same finish on steel. In Table 1, the chemical composition of wrought iron is compared to that of pig iron and carbon steel . Although it appears that wrought iron and plain carbon steel have similar chemical compositions, that

7373-498: The same year he proposed an extended water supply for the London metropolis, and in 1850 designed a system of drainage for Southwark. In 1858–9 he was a member of the royal commission on harbours of refuge, of which Admiral Sir James Hope was chairman. Vetch retired from the Admiralty in 1863; his office of conservator was then abolished and the duties transferred to the Board of Trade . He

7474-512: The seal and on the coat of arms of Haddington. John Martine wrote Reminiscences of the royal burgh of Haddington and old East Lothian agriculturists in 1883. On 5 September 1618 a debt collector from Edinburgh, Thomas Allan, was attacked by Isobel Addington and 60 or 80 other women who beat him and then dragged him by the feet out of her house. People who have received the Freedom of the burgh of Haddington include: There are several churches in

7575-625: The seventeenth century, and it is now the seat of the Duke of Hamilton and Brandon . The Parish Church of St Mary's is today part of the Church of Scotland , but includes an Episcopalian chapel, the Lauderdale Aisle , containing the mausoleum of the Maitland Earls of Lauderdale . It is the longest parish church in Scotland and is in regular use for worship and musical events. It is directly adjacent to

7676-516: The site of the old station (Lemac), and various smaller industrial units and garages. Haddington is also home to the offices of the local newspaper the East Lothian Courier . There is a farmers' market held on the last Saturday of the month in Court Street. The town centre largely retains its historic street plan with Court Street, High Street, Market Street and Hardgate defining the edges of

7777-450: The southern edge of the town centre and Letham Mains is in the Letham estate on the western outskirts . Prior to October 2012, Haddington Infant School was two separate buildings; the main building (built in 1897) and the annex (built in 1965) was located at Victoria Road/Meadowpark and the old St. Mary's Primary School was located at Tynebank Road. Following the discovery of structural defects at

7878-508: The station in the 1940s (isolated as it then was at the western extremity of Haddington), the town has since expanded significantly. Between 1951 and 1981, the population of the town grew by 54%. It remains to be seen whether further expansion of the town will lead to a reinstatement of Haddington's railway line, since there are congestion issues on both the East Coast Main Line and at Edinburgh Waverley railway station . An account of

7979-670: The summer house, walled garden, ice house, chapel, and gates. The world's earliest surviving records of a lodge of free gardeners come from Haddington, in 1676. Lennoxlove House , a historic thirteenth-century house and estate, lies 1 ⁄ 2 mile (800 metres) south of Haddington. Built by the Giffards of Yester , it was originally named Lethington . It was once home to the Maitland family, notably Sir Richard Maitland , and his son William Maitland of Lethington , Secretary of State to Mary, Queen of Scots '. The Maitlands left Lennoxlove in

8080-465: The top of the puddle and was fished out of the melt as puddle balls, using puddle bars. There was still some slag left in the puddle balls, so while they were still hot they would be shingled to remove the remaining slag and cinder. That was achieved by forging the balls under a hammer, or by squeezing the bloom in a machine. The material obtained at the end of shingling is known as bloom. The blooms are not useful in that form, so they were rolled into

8181-512: The town's former granary. In addition to the lending library the Centre comprises East Lothian Council's Historical Archives, Local History Collections and Reading Room, a new museum of East Lothian (with a temporary exhibition gallery), a computer suite and community room. The Centre is named after a local minister whose bequest of books and money in 1717 gave the town one of the earliest community libraries in Scotland. Haddington sits 1 km south of

8282-676: The town's relatively unaltered medieval plan and significant survival of historic buildings was recognised as early as the 1950s, with Haddington subject to an Improvement Scheme, Scotland's earliest, which saw many period properties rehabilitated by the Town Council (under the leadership of Frank Tindall as Director of Planning) and a pioneering town colour scheme developed, resulting in the distinctive and colourful townscape seen today. Some comprehensive redevelopment did occur, chiefly around Newton Port and Hardgate to allow for widening of these narrow streets to improve motor traffic flow. This included

8383-745: The town. These include: Kenny MacAskill , Depute Leader of the Alba Party has served as the MP for East Lothian since 2019 . Paul McLennan of the Scottish National Party has served as the MSP for East Lothian since 2021 . There are four councillors for Haddington and Lammermuir. Haddington has three state primary schools; the first being Haddington primary school,the second being St. Mary's RC Primary School and third being Letham Mains primary school. Both HPS and Saint Mary’s are located adjacent to Neilson Park at

8484-560: The working-over of the metal spread out copper, nickel, and tin impurities that produce electrochemical conditions that slow down corrosion. The slag inclusions have been shown to disperse corrosion to an even film, enabling the iron to resist pitting. Another study has shown that slag inclusions are pathways to corrosion. Other studies show that sulfur in the wrought iron decreases corrosion resistance, while phosphorus increases corrosion resistance. Chloride ions also decrease wrought iron's corrosion resistance. Wrought iron may be welded in

8585-467: Was a branch from the East Coast Main Line at Longniddry and terminated at Haddington railway station and freight depot in the area between West Road and Hospital Road. The line was 4 + 13 ⁄ 16 miles (7.7 kilometres) in length and had stations at Coatyburn Siding and Laverocklaw Siding before terminating in Haddington. The line was opened on 22 June 1846. The branch had only a single track, though bridges and embankments were built to allow for

8686-479: Was adopted (1865 on). Iron remained dominant for structural applications until the 1880s, because of problems with brittle steel, caused by introduced nitrogen, high carbon, excess phosphorus, or excessive temperature during or too-rapid rolling. By 1890 steel had largely replaced iron for structural applications. Sheet iron (Armco 99.97% pure iron) had good properties for use in appliances, being well-suited for enamelling and welding, and being rust-resistant. In

8787-524: Was appointed consulting engineer to the admiralty; in 1847 he was appointed a member of the new harbour conservancy board at the admiralty, the other members being John Washington and Charles Bethune of the Royal Navy Washington was withdrawn from the board in 1849, and in 1853 Vetch was appointed sole conservator of harbours. In 1849 he was appointed one of the metropolitan commissioners of sewers, an honorary office which he held for four years. In

8888-529: Was appointed one of the three commissioners to carry changes in tenancies, John Douglas Cook acting as secretary. In 1844, 1845, and 1846 Vetch was examined by the Commissioners Upon the Subject of Harbours of Refuges, and at their request wrote a report on wrought iron frameworks in the construction of piers and breakwaters. In 1845 he reported on designs for a harbour of refuge at Dover. In July 1846 Vetch

8989-465: Was author of: Reports were published by Vetch between 1847 and 1859 on the following harbours: Ramsgate, the Tyne, Cork, Wexford, the Isle of Man, Holyhead, Port Patrick, and Donaghadee, Galway, Portsmouth, Table Bay, Port Natal, Point de Galle. Feeling the want of a good map of Mexico, Vetch accumulated astronomical and barometrical observations while there, measured several short base-lines, and triangulated

9090-484: Was considered sufficient for nails . Phosphorus is not necessarily detrimental to iron. Ancient Near Eastern smiths did not add lime to their furnaces. The absence of calcium oxide in the slag, and the deliberate use of wood with high phosphorus content during the smelting, induces a higher phosphorus content (typically <0.3%) than in modern iron (<0.02–0.03%). Analysis of the Iron Pillar of Delhi gives 0.11% in

9191-463: Was described in The Buildings of Scotland as "the most important building of the orthodox Palladian school in Scotland." John Henderson built the walled garden in 1783, and the castellated stable block in 1785. The park in front of the house, possibly landscaped by James Bowie, is today entirely ploughed. A victim of dry rot, the house was demolished in 1928. All that remains of Amisfield today are

9292-571: Was drawn up in May 1681, and major capital invested in new machinery, but the New Mills had mixed fortunes, inevitably affected by the lack of protectionism for Scottish manufactured cloth. The Scots Courant reported in 1712 that New Mills was to be "rouped" (auctioned). The property was sold on 16 February 1713 and the machinery and plant on 20 March. The lands of New Mills were purchased by Colonel Francis Charteris and he changed their name to Amisfield. As

9393-612: Was elected a fellow of the Royal Geographical Society in 1830, an associate of the Institution of Civil Engineers in 1839, a member of the Société Française de Statistique Universelle in 1852, and was a member of other learned bodies. He died on 7 December 1869, and was buried in a family vault (plot no.5277) on the western side of Highgate cemetery . The vault is overgrown with a broken and illegible monument. Vetch

9494-515: Was hypothesized that the type of iron had been rejected for conversion to steel but excelled when tested for drawing ability. During the Han dynasty (202 BC – 220 AD), new iron smelting processes led to the manufacture of new wrought iron implements for use in agriculture, such as the multi-tube seed drill and iron plough . In addition to accidental lumps of low-carbon wrought iron produced by excessive injected air in ancient Chinese cupola furnaces . The ancient Chinese created wrought iron by using

9595-471: Was moved to the Blists Hill site of Ironbridge Gorge Museum for preservation. Some wrought iron is still being produced for heritage restoration purposes, but only by recycling scrap. The slag inclusions, or stringers , in wrought iron give it properties not found in other forms of ferrous metal. There are approximately 250,000 inclusions per square inch. A fresh fracture shows a clear bluish color with

9696-445: Was not the intention. However, the design of a bloomery made it difficult to reach the melting point of iron and also prevented the concentration of carbon monoxide from becoming high. After smelting was complete, the bloom was removed, and the process could then be started again. It was thus a batch process, rather than a continuous one such as a blast furnace. The bloom had to be forged mechanically to consolidate it and shape it into

9797-528: Was of little advantage in Sweden, which lacked coal. Gustaf Ekman observed charcoal fineries at Ulverston , which were quite different from any in Sweden. After his return to Sweden in the 1830s, he experimented and developed a process similar to puddling but used firewood and charcoal, which was widely adopted in the Bergslagen in the following decades. In 1925, James Aston of the United States developed

9898-509: Was passed by the Parliament of Scotland to encourage the production of fine cloth, and in 1645 an amendment went through stating that the masters and workers of manufactories would be exempt from military service. As a result of this, more factories were established; these included the New Mills. This factory suffered during the Civil War with the loss of its cloth to General Monck . A new charter

9999-455: Was probably born in Haddington and Knox Academy , the local high school, is named after him. Haddington is located predominantly on the left bank of the River Tyne , and was once famous for its mills. It developed into the fourth-largest town in Scotland during the High Middle Ages , and later was at the centre of the mid-eighteenth century Scottish Agricultural Revolution . In 1641, an Act

10100-473: Was the chemical composition and others that it was whether the iron heated sufficiently to melt and "fuse". Fusion eventually became generally accepted as relatively more important than composition below a given low carbon concentration. Another difference is that steel can be hardened by heat treating . Historically, wrought iron was known as "commercially pure iron"; however, it no longer qualifies because current standards for commercially pure iron require

10201-527: Was then sent to the Barbary Coast , and went on from Tangier to Tetuan to report on the capabilities of the country to furnish engineering supplies. In March 1812 Vetch left Cadiz for Elvas , sailing up the Guadiana River with a company of sappers and miners to take part in the siege of Badajos . On the evening of 6 April, when the final assault took place, he made a lodgment with three hundred men in
