Supervised by Krzysztof Jan Chuchra, EWH‟s Urban Analyst, she revisited and expanded on the research which I had undertaken in connection with the Northumberland Street lighting scheme as long ago as 1969-70 (see page 8). Much help was given by Steve Francey of the Council Lighting Department. The paper must be regarded as a draft, for several reasons. As stated on page 28, access to the reserve collections of the National Museum of Scotland has been impossible recently owing to the major redevelopment of the Museum, but should become possible during the next few months. Some interesting and relevant electrical equipment will be found there, and also possibly in the collections of the Science Museum in London. As stated on page 17, measured drawings of the handsome gas lantern introduced in about 1860 are being produced in a collaboration between the Council Lighting Department and the University of Edinburgh, but the project goes far further than that. The lantern, and the earlier standard illustrated on page 16, are being modelled by Jonathan Knox, under the direction of Richard Coyne, Professor of Architectural Computing at the University of Edinburgh, and the results will be fascinating. The computer modelling project will be completed within the next few months, and I expect to produce a final version of the whole paper by the middle of this year.

Oil Lighting „My tea is nearly ready and the sun has left the sky; It‟s time to take the window to see Leerie going by; For every night at teatime and before you take your seat, With lantern and with ladder he comes posting up the street…‟ R.L. Stevenson Pic. 1 One of many illustrations to R.L. Stevenson‟s book A Child's Garden of Verses - a scene from a lamplighter‟s everyday life. Carrying a ladder in the right hand and a pot of oil in the left, the lamplighter would use these to fill up the oil reservoir or cruse (recalling the biblical story of the widow‟s cruse of oil that supplied Elijah during a famine). The wall-mounted oil lamp was a typical design widely used in Edinburgh Old Town starting from the 18th century. Edinburgh Town Council, as predecessors of the City of Edinburgh Council, appointed the first public lamplighter in the Old Town in 1701. This followed the issue of a Royal Charter in 1688, granted by King James II and VII. The Charter empowered the Council to install lanterns where they considered it appropriate. According to Charles Boog Watson‟s remarkable manuscript Notes on the history of Edinburgh, the earliest indication of public street lighting installation probably goes back as far as 1684, when the Lord Provost brought 24 lanterns from London to be fitted up in the High Street and Cowgate. This made these two the first streets in Edinburgh to be lit with public street lighting. Pic. 3 Original wall-mounted oil lamp, the globe later perforated at the bottom to accept a gas pipe Pic. 2 Advocate‟s Close, High Street, 1890 (c) Edinburgh City Libraries. Capital Collections www.capitalcollections.org.uk 4 Long before the implementation of the Royal Charter, starting from 1633, the Council issued an order that obliged private citizens, primarily barbers, candle makers, apothecaries and taverners to hang candle lanterns outside their doors from 5 pm to 9 pm, “save when the moon makes it unnecessary”. In 1733 the Lord Provost was to purvey lamp glasses when in London. Consequently, fifteen lamp posts and 30 lamp glasses were shipped to Edinburgh the following year. In 1742 the Council owned 99 lamps for streets and closes and 46 stoups (wooden posts) “for setting the lamps on”. The number of lamps in the Old Town continued to increase over the next 50 years so that by 1786 the Council were responsible for the maintenance of 307 lamps. Though not coming from Edinburgh, the following illustration by William Pyne provides a deeper insight into what the work of lamplighters may have looked at the beginning of the 19th century. The illustration is from „The Costume of Great Britain‟ published in 1808 in London. It shows a lamplighter up a ladder, holding the lid of a street lamp in one hand while passing the centre of the lamp down to a young boy carrying a jug of oil. The centre of the lamp most probably comprises a floating wick in a glass dish, with glass bullions (produced in huge numbers during the manufacture of crown glass) arranged on each side. The whole thing was held together with wire and possibly tin or tinplate. The bullions may have acted as crude lenses, making the light of the wick more visible along the line of the street. The fact of a young boy‟s presence in both Pic. 1 and Pic. 4 gives an idea about the custom of lamplighters engaging young assistants in their work. Pic. 4 William Pyne „Lamp lighter‟, 1808 Some private citizens made petitions requiring lantern installations in their streets. Thus, in 1761 citizens living in the Grassmarket applied for more lamps. Two broken ones had to be repaired, and three new ones provided against the next season, making twelve in total. However, in 1764 two lamps from the Grassmarket were to be put „in the dark West Bow‟, which indicates the intention for more balanced and evenly spread improvements around the city. 5 Pic. 5 Old Assembly Rooms, West Bow, J. Scene, 1817 (c) Edinburgh City Libraries. Capital Collections www.capitalcollections.org.uk Pic. 6 View of West Bow, J. Scene, 1817 (c) Edinburgh City Libraries. Capital Collections www.capitalcollections.org.uk By 1785, when much of the First New Town had been built, the Council had installed 116 lamps there, apparently placed either on wooden posts attached to the railings or, as was common in the Old Town, on wall brackets. 1785 was also the year in which the Police Commissioners were established by Act of Parliament. Their responsibilities included lighting and cleaning the streets, and their proceedings were recorded in the Minutes of the General Commissioners of Police, held in the City Archives. For many years, the Minutes included brief but regular reports from the Lighting Committee, but in 1818, no doubt because of the prospect of introducing lighting by gas, the Committee seems to have become more active – so much so that it acquired a separate Minute Book in January 1820 - see Pics. 11 and 12. Pic. 7 Detail featuring original wall-mounted oil lamp later converted to gas. In the background, an early gas lamp with a square lantern on top, Swarbreck, 1837 Pic. 8 Details featuring original railing-mounted oil lamps, Shepherd, 1829 6 The Minutes tell us a lot about oil lighting. The Committee agreed in August 1820 to divide the area within the Police Bounds “into two districts as equal as possible”, east and west of a line from Canonmills to Minto Street, by way of Hanover Street, the Bridges and Clerk Street, and appointed Contractors for each district, following a tendering process. It was agreed that the Lighting Contract would include the following: “…the Contractor shall also furnish such new lamps with heads, cruses and appurtenances complete as may be needed at the rate of XX each – the heads to be painted inside and outside with not less than two coats of oil paint – globes not to be under 3lb weight – nor under eleven inches diameter. The lamps, cruses and appurtenances to be delivered over to him in sufficient condition at the commencement of the contract and he to furnish cellarage – keep, uphold and maintain them in the like condition during the currency thereof and shall punctually replace upon his own expense every lamp that may be broken and that against the next day after such lamp shall be so broken and at the expiry of the contract deliver over the whole in sufficient order and condition”. The Committee also agreed in August 1820 that “…the Contractor shall furnish the lamps with a sufficient quantity of the best Greenland whale oil and two wicks of sixteen threads of the best Oxford cotton conform to specimen to be produced – that he shall cause the lamps to be trimmed daily and the globes to be cleaned at least three times in the week and for that purpose keep a sufficient number of hands”. Although some of the oil certainly came from Dundee, most of it came from Hull, which at that time had 2,000 men employed in the trade and could boast over 60 whaling vessels, making it the largest fleet in Britain. The best oil was defined as „being the tops of the casks‟. The intention in terms of the Contract was that the lamps should burn until 3 am. However, this was hard to achieve with accuracy, as the Minutes of October 1820 show: “…let the same quantity of oil be put into any two lamps and both equally trimmed by the most expert and experienced lamplighters, the one will continue burning from half an hour to an hour longer than the other”. Some residents found the wooden posts not elegant enough. In 1787 John Hunter, Writer to the Signet, became the first resident to receive permission to replace the post outside his house at 4 Queen Street with an iron lamp standard fixed to the railings. This inaugurated the installation of decorative wrought and cast iron standards in Edinburgh. Later some other proprietors put up their own lamps. On the north side of Charlotte Square (and occasionally elsewhere) wrought iron standards of c. 1800 can be found. In 1953, reproductions of this design were erected along the other three sides of the Square. Later, a simplified version was widely used elsewhere, notably on The Mound and in the Moray Feu, Heriot Row and Calton Hill terraces. In Heriot Row a large cast standard of c. 1810 was put up privately in front of many of the houses, and in Queen Street a different, though similar, design was used. This latter design was also used in Ann Street and in Howard Place, where the top section of it can be seen mounted on the garden walls. By 1819 the Council had begun to replace wooden posts with cast iron standards, initially erected by the Contractors („cast iron lamp pillars including lead, fixing and painting £1 6s. 0d. each‟ in 1819) but later by the Commissioners themselves (14s. 6d. each from John Anderson‟s Leith Walk Foundry in 1820). Only five of the 1819 standards now survive: on the north side of the Advocates' Library (visible from George IV Bridge), at 125 George Street, at 12/14 Stafford Street, and at 22 and 38 York Place. The last of these was originally fitted with a linkhorn (used to extinguish the link boy‟s torch once he had escorted someone to the house), as Pic. 9 shows. The Charlotte Square standards had linkhorns (though the later reproductions did not). The “Heriot Row” stan- Pic.9 Linkhorn that used to be a part of 38 York Place lamp standard (c) Stones and Curiosities of Edinburgh, G. A. Fothergill 7 The standard at 38 York Place was used as a pattern for the Northumberland Street lighting scheme in 1971. Unfortunately, due to the casting process, the blemish on the back, where the linkhorn had been attached, appeared on the front of every copy, but better results were obtained thereafter using an aluminium pattern made from the standard at 125 George Street for the Edinburgh New Town Conservation Committee. Examples can be seen in Drummond Place, Fettes Row, Royal Circus, India Street and the Raeburn Feu. Wrought iron bracket attached to the standard. The triangular opening was filled in Northumberland Street, because of safety concerns, but left open on all subsequent reproductions. Copper clips over the cope of the railing are secured by nuts on the front of the standard – back view Pic. 10 Original cast iron standard at 38 York Place Oil lighting can never have been very effective. Evidence of this can be found in the Minutes. Pic. 11 Title page of Minutes of Committee of Commissioners of Police for the Lighting Department 1820 – 1826 Pic. 12 From the Minutes of 14th January 1820 8 As can be read on Pic. 12: “…The Commissioners of the First Ward of Police, having this evening inspected all of the lamps in their division, found the great proportion giving light so very feebly, there is evidently more management required, in the execution of this department….” The Minutes continue: “Several of the lamps were out, and a number with only one wick burning, at the hour of ten o‟clock. In the close from the West Bow to the Cowgate, the only access, without going round by the Grassmarket, one lamp was amissing of the only two placed in that entry. As they consider this a most material approach in that direction they would recommend three lamps, being well bestowed in this close, and the new one to be placed above the few steps in the middle of it, as the great declivity must occasion frequent accidents from want of being guided by light. Another lamp at the Corner of Mr. Main‟s the Stationers Shop, in West Bow would do good; and, there being one in the close opposite where are very few Inhabitants, it is submitted whether it could not be better applied.” It was also suggested that an Inspector “… going round at different times in the evening, and proving effectually, might aid the measure very materially, as light there should be, and light there may be; for which only a little more time and trouble (well applied) is required.” Pic. 13 Steep crescent of West Bow, 1971 9 II. Arrival of Gas Lighting Pic.14 Lamplighter on Victoria Terrace, c. 1930. Lamplighters were still a common sight in Edinburgh until the 1960s. This lamp standard still survives. (c) Edinburgh City Libraries. Capital Collections www.capitalcollections.org.uk Few knew that the solution for „brighter streets‟ was already on its way. 1792 was the year when the revolutionary idea of gas lighting was pushed forward by William Murdoch, who was the first one to use coal gas for lighting his house in Redruth, Cornwall. Gas lighting was first introduced to Edinburgh in 1819 by the erection of eighteen pillars (probably wooden posts) for gas lamps on North Bridge. 10 This prominent event was preceded by the establishment of the Edinburgh Gas Light Company in 1817, north of the Canongate. Pic. 15 Canongate with its abundance of oil lamps, 1830 (c) Edinburgh City Libraries. Capital Collections www.capitalcollections.org.uk In November 1819 the Committee had under its consideration the subject of lighting streets with gas and it resolved that “…that part of the High Street from the Tron Church to the Parliament Close shall on both sides be forthwith lighted with gas, and they have given directions that estimates of the expense be immediately obtained and submitted to them, that the measure may be carried into effect without delay.” From a design point of view, the Old and New Towns used different strategies. While for the former it was common to convert existing, mostly wall mounted, oil lamps to gas, in the New Town, on the contrary, new lamp standards were erected. In October 1820, the Minutes recorded that “a neat and very handsome pillar was provided as a pattern with a contrivance to embrace the cope of the railing without incumbering the pavements”, and this is referred to in the wonderfully detailed specification for the first gas standards on page 14. We do not know whether any were actually mounted in this way, but in March 1824 the Minutes recorded that “…on account of numerous objections urged by proprietors to placing irons on their railings, the Committee has found it necessary to order common oil pillars mounted on wooden posts”. Nothing was said about the cause of the objections, but perhaps there were concerns about safety. At all events, some other way of supporting the new standards had to be found, and consequently it was agreed – possibly as early as December 1821, when the Committee agreed to “contract for the supply of stone pillars for supporting the gas lamps” – to place them on the pavement, each one to be supported by a pall stone or bollard. Many of the pall stones are shown in Samuel Swarbreck's superb set of Edinburgh prints, dated 1837 - see Pics. 17 and 20. The specification for the lanterns, also on page 14, is also wonderfully detailed – “the ball on the top to be...turned perfectly smooth for gilding...the whole to be...glazed with best crown glass”. As gas lighting spread, the Council‟s short-lived oil standards were taken down, but the Council had no power to remove private oil standards, as this indignant letter from Mary, Lady Clerk, 100 Princes Street, laid before the Commissioners in October 1821, shows: “Dear Sir, I beg leave to apologize for troubling you but have no other person to apply to, for a very impertinent proceeding of the people who light the lamps (none of whom I know). Twice they have attempted to take down my lamp posts – the first time I fortunately was walking before my door and instantly stopped them – but this morning before I was awaked, they again came and was beginning; when my man servant, with the utmost difficulty prevented one of the posts being taken away. They might as well take down the door of my house being all my own property and paid for with my own money – My fear is, when I am out of town some day they may steal them away, and though I would prosecute them for theft – yet that would be troublesome, and as I choose when I have company to have a light at each side of my door, I see no reason that these most impudent and impertinent people are to prevent me. I beseech you tell me how to act, or rather act for me to prevent their insolence in future. I am Dear Sir Your obliged friend. (signed) Mary Clerk... To Capt. Brown, Police Office.” 11 The third specification on page 14 is for the provision of circular lanterns with glass globes „and tinplate heads‟ for wall mounting. Note that if existing oil lanterns were to be converted to gas, estimates were wanted "for perforating the bottoms of the globes with a cutter 5/8 in: diam., and punching a sufficient number of holes into the old rims to admit air". Pic. 7 shows this well. On the following print one can see an abundance of lamps – oil on the left and gas on the right. Pic. 16 South Bridge, Swarbreck 1837 In depicting the North Bridge (Pic.17) Swarbreck included both designs – globes with gas fittings on wooden posts attached to the bridge wall, on the left, and lanterns on cast iron pillars supported by pall stones, on the right. Pic. 17 North Bridge Street, Swarbreck, 1837 12 Gas lighting was considered a great wonder, „most beautiful and brilliant‟ as expressed by the Scottish writer George Combe. “What a folly, to have a diamond necklace or a Correggio, and not to light your house with gas”, thought the writer and poet Sydney Smith in 1820. Further undertaking included “…taking down 27 oil lamps from the High Street, to remove the whole from the North Bridge and that the nineteen globes used on High Street last season be replaced or lighted with gas light single jet burners – that the lanterns be fitted to the pillars on the North Bridge and supplied with large batwing burners.” According to the data submitted to the Lighting Department for the month of May 1820 the total number of lamps was 4781, of which 1980 were gas lit. The specification one on page 14 included provision for a batwing burner, and in September 1820 it was agreed that "large batwings be substituted in place of the small ones presently in use at the corners of the South and North Bridges, and corner of High Street".

The gas to be introduced into the lantern by means of a copper tube 3/8 inch diameter with the necessary brass coupling screws; Passing from the end of the service pipe through the curbstone and pillar; It will be fixed by means of a plate fitted on the tube in the recess formed in the centre of the cross; The cross must be filled up with melted lead; Above that a brass screw socket, hard soldered to the end of the tube must project; Upon this a brass stop cock with a brass tube and a socket to hold the batwing burner will be fitted.‟ Lanterns Top and bottom frames to be cast each in one piece; The ribs also to be cast and to have malleable tangs 1/4 in square, hard soldered into the ends for the purpose of riveting the whole together, previous to which the ends must be filed off to the proper level, so that the joining may not be observed; The door to be cast in one piece and to be fitted on in the same way as the pattern The top of the lantern to be made of tinplate, not less than XXX in strength, with a black iron plate riveted inside to preserve the upper part from the effects of the burner acting upon it; The ball on the top to be of coarse tin cast and turned perfectly smooth for gilding; The whole to be japanned outside and inside – glazed with best crown glass. And fixed to the top of the pillar, by 4 screw bolts and nuts, and in every respect to be finished same as the pattern. Globes with Gas Fittings The globes to be made of good glass 12 in: diameter and 12 in: deep, with a perforation in the bottom 5/8 inch diam., and to weigh not less than 4 pounds each; To be set in a rim of tinplate with 3 triangles in each to support them in the iron; The heads to be made of tinplate not less than XX in strength and to be painted outside and inside with not less than 2 coats of good oil colour; The gas to be conveyed from the screw cap of the iron service pipe until it reaches the globe by a copper tube 3/8 inch: diam., inside and the bottom of the globe by a tube ¼ in diam.; The pipe for each globe to be fitted with a stop cock for the gas, brass socket for the jet burner with a stop cock connected to run off any water that may lodge under the burner together with the necessary brass coupling screws similar to those now in use in the High Street; In the event of the globes presently in use being applied to lighting with gas, estimates are wanted for perforating the bottoms of the globes with a cutter 5/8 in: diam., and punching a sufficient number of holes into the old rims to admit air. Pic. 20 Regent Bridge, Swarbreck, 1837 14 In December 1821 the Committee decided that from 1 st January 1822 the public gas lamps should be lit at one hour after sunset – that the one half be extinguished at three o‟clock am, and the remainder continued till one hour before sunrise. The lighting installations continued around the city in the following years. In August 1822 it was resolved by the Committee that the following streets be lighted with gas without delay with the following number of lamps: St. Andrew Streets and Square St. David's Street Hanover Street – South Frederick Street Castle Street Greenside Street North Bridge Street 39 7 14 14 14 36 38 Total - 162 In May 1822 the state of street lighting during the previous two years was analysed. September 1820 to May 1821 September 1821 to May 1822 Oil lamps – 4765, Gas lamps – 37 Total - 4802 Oil lamps – 4731, Gas lamps – 408 Total – 5339 Making an annual increase of 537 Clearly, supporting standards on pall stones could only be temporary, and in September 1827 a sketch of a new gas pillar drawn by William Burn, the leading Scottish architect of the day, was submitted to the Committee and preferred over other designs. The specification for the new standard was agreed in December 1827: “The pillars to be cast in best number 2 pig iron with a smooth skin, without blemishes or defects, and in all respects equal to the casting exhibited in the Police office… The malleable iron work to be of best English iron, and finished at least as well as the pattern, must have a coat of linseed oil laid over it when hot from the forge, to prevent the formation of rust…The fitting of the globe iron at the top to be correctly made, and to stand fair and true on the shaft. The fitting of the shaft to the pedestal to be fair and solid, and the hammered iron key to be adjusted exactly to the proper length. The whole work to be done in such a way that the Police Establishment shall not be put to any expense in after adjustment, and the Inspector of Police to be at liberty to reject any pillar, which he may conceive to be defective in any particular, or in any way inferior to the casting in the Police office. The contractor to bore the holes in the stone for fixing the batts of the pedestal – to deliver them in such numbers as may be required, and to batt them properly in with lead wherever they may be wanted within the police bounds, and to paint them when fitted up with two coats of oil paint of any colour that may be required. The pattern to be furnished by, and to be the property of, Police Establishment”. Square stone blocks with five holes (four near the corners, where batts or lugs on the cast iron standard were secured to the base, and one in the middle, where the gas pipe came up) as mentioned in the specification can still be found. Pic. 21 A square block in Nelson Street, 2010 Note how it sits forward of the line of the kerb. Pic. 22 A square block in Dean Terrace, 2010 Fragments of batts or lugs from the standard broke off when it was removed, and remain in the block. 15 0 Pic. 23 The Royal Institution (later the Royal Scottish Academy and now part of the Scottish National Gallery) and Princes Street with standards by William Burn, Swarbreck, 1837 Remarkably, some of these very standards have survived, and until recently two could be seen in the garden of the Museum of Edinburgh at 142-146 Canongate. They will be re-erected shortly, nearby. The Commissioners had decided in October 1827 to have street names cast in raised letters on the ladder bars. The first circular lantern had a tall chimney, but this design was superseded in about 1860 by one with a glazed upper section – which is represented by the modern reproductions around the Scottish National Gallery, and elsewhere. The decorative finial was made of glass – described as a “crystal knob” in the Holyrood Glassworks catalogue (Pic. 25). Ladder-bar with cast Princes Street Pic.24 Museum of Edinburgh, original fluted standards designed by William Burn (with later lanterns). The square bases (see Pic.23) are not visible because they have been buried. Nothing is said in the Minutes about paint colours, but recent research by Michael Pearce of Historic Scotland suggests that dark grey (white-lead oil paint loaded with carbon black pigment) was used initially, superseded by dark green from around 1890 and a lighter shade of green from around 1920. 16 Pic, 25 Lantern with crystal knob on top from the Holyrood Glassworks catalogue Pic. 26 The Heart of Midlothian, looking up the Lawnmarket, J.

A globe from one of these lanterns has fortunately survived (Pic. 28). It is much more substantial than the modern perspex reproductions would suggest, weighing 7lbs 6oz (3.35 kg) and with a diameter of 11 ins (12 ¼ ins at the rim). Note the second hole drilled near the base, through which the lamplighter would push his spirit torch, on the end of a pole. 17 Pic.27 Princes Street from the west, G.W.

Pic.33 An Edinburgh gas lantern, converted to electricity but still in use, in Belgrave Mews, 2010 19 In 1827 the Committee accepted that globes for new gas lamps were preferable to lanterns. The decision was made after the stormy night of 7th December of the same year, “as in the exposed situation of Atholl Crescent, not one [globe] was blown out, while in York Place, which is better protected, most of them [ie lanterns] were extinguished”. By 1826 most of the New Town streets, as well as Leith Walk and Lothian Road, were gas-lit. By 1847 there were as many as 761 public gas lamps in Edinburgh. In 1856 an Act of Parliament was passed returning the functions of lighting and cleaning from the Police Commissioners to the Town Council. At this time, a Lighting and Cleaning Department was formed. Incandescent gas mantles were invented in 1885 and by 1895 were reasonably cheap. In Edinburgh, incandescent mantles, in the four-sided lanterns that many of us remember, were fitted between 1900 and 1907 and in all new lamps thereafter.

On 21st April 1965 a small ceremony organized by the City Council was held in Ramsay Garden, at which the last gas lamp in Edinburgh was turned off. 23 III. Electricity Era Already in 1831 Michael Faraday made the first dynamo which was to lead to the supply of cheap electricity. Electricity arrived in Edinburgh first in 1881 with the trial installation of electric street lighting in Princes Street, Waverley Bridge and North Bridge. In 1895 the first electric power station was established at Dewar Place. In 1898-99 McDonald Road Power Station was built for Edinburgh Corporation Electricity Department to complement the existing power station in Dewar Place, and supplied electricity to domestic, commercial and industrial consumers, and for street lighting. The decision to build a second power station indicated the growing scale and great expectations of electric lighting in the city.

According to the annual Report of the City of Edinburgh Lighting and Cleaning Department for the year ending 15 th May 1913 “For the public street lamps both gas and electricity are employed, the former by means of inverted incandescent burners, and the latter almost wholly in the form of arc lamps situated on the tramway routes and main thoroughfares.” Early street lighting by electricity involved arc lamps, their typical shape being due to the mechanism which created or “struck” and thereafter maintained the arc between two carbon electrodes. They produced a brilliant light, but were expensive and troublesome to maintain.

Breakages are from these causes very frequent, the replacing of the damaged or broken lanterns and pillars representing a considerable annual expenditure.” Mackenzie Brothers, later Mackenzie & Moncur, were Edinburgh iron founders and heating engineers. They were general manufacturers of cast iron goods but their distinctive lighting standards, which came out initially in the 1890s (they can be dated reasonably accurately from pictures of the Edinburgh tramway system) have proved very long lived. Quite a lot are still in use today in Edinburgh, Westminster and Southport. Despite the fact that Mackenzie Bros were operating in several regions across the United Kingdom, Edinburgh probably had more Mackenzie standards than anywhere else and quite a number remain.

All major routes were completed by 1973. Unfortunately, no detailed records have survived, but some interesting equipment – notably a number of arc lamps – exists in the reserve collections of the National Museum of Scotland. Access to these collections has been impossible recently owing to the major redevelopment of the Museum, but should be possible during the first half of 2012. 28 IV. Foundries Two iron foundries are still active in the Edinburgh area – Charles Laing & Sons Ltd, at Beaverbank Place, near Canonmills, and Ballantine Bo‟ness Iron Co Ltd, at Bo‟ness, on the Forth estuary. Both have a long history and produce work of the highest quality, Laings specialising in smaller items and Ballantine‟s in larger, though there is a broad overlap. The following photographs were taken on a visit to Ballantine‟s foundry in June 2010. The process of metal casting in the foundry consists of the following main steps: Pic.47 Iron being collected for melting down by magnetic crane Pic.49 A greensand mould being prepared Pic.48 Molten iron in the electric furnace Pic.50 Molten iron being poured Pic.51 A line of moulds cooling down The early shift usually prepares the moulds and sees the iron poured. The late shift removes the castings for finishing, and leaves everything ready for the early shift the next day, so it all follows a daily cycle. 29 V. “Conservation” Lighting sChemes Most of the cast iron lamp standards in Ann Street are replicas erected by the Ann Street Society between 1957 and 1960. Some of the original standards in poor condition were replaced, and replicas were added in order to make up the number required for electric lighting, which was introduced when the pavement-mounted gas lamps were removed in 1963. Electric imitation oil lamps were fitted to the standards by the Corporation. Later, this formula was followed elsewhere, notably in Northumberland Street in 1971 (see page 8). The most recent such scheme was carried out in Lynedoch Place in 2007. Ann Street and Lynedoch Place are by the same architect (James Milne) and have front gardens with low walls, surmounted by railings, along the pavement, as does Howard Place (by James Gillespie Graham). Ann Street and Howard Place both have wall-mounted lamp standards for oil lamps, and this was ample justification for reproducing the same design for Lynedoch Place. Fortunately, Ballantine‟s already had an aluminium pattern for the full-height standard of which the wall-mounted standard forms the upper section (Pic.52). Pic.52 Aluminium pattern used for the production of lighting standards for Lynedoch Place in 2007 One full height standard and nine wall-mounted standards were required, and the lanterns were all connected to a single timeswitch. The estimated cost of £30,000 was divided equally between the residents, EWH and the City Council, with the Council also agreeing to cover any overspend. This elegant and successful scheme, part of a larger programme of improvements, is clearly visible on a major traffic route. 30 Pic.53 Lighting standards installed on Lynedoch Place, LDN Architects 31 Appendix Statement and Recommendations for Historic Street Lighting This statement was prepared by Edinburgh World Heritage in 2011 in order to inform the forthcoming City of Edinburgh Council‟s lighting strategy, which amongst a number of issues regulates management of historic street lighting in the World Heritage Site. The statement is one of the outcomes of the study in hand and its main function is to inform the planning policy by explaining the importance of street lighting in the context of the Old and New Towns of Edinburgh World Heritage Site‟s Outstanding Universal Value. This refers to the recognition given by the policy ENV 1 of the Edinburgh City Local Plan. Introduction Historic street lighting forms an integral part of Edinburgh's streetscape, which is one of the defining elements of the World Heritage Site's Outstanding Universal Value. Its historic quality significantly contributes to the historic atmosphere of the city, contributing to its overall historic authenticity and integrity, setting it apart from other cities which have not retained their historic detail. Despite significant urban changes in Edinburgh following the development of the New Towns, the principles of the street lighting have not changed significantly; however a slightly different approach had to be applied in the city's juxtapositioned townscapes respecting scale, architectural context and order. Lighting perception How we now see the buildings and streets of the World Heritage Site at night is very different to the original intention. The original oil lanterns would have lit doors, steps, and some of the façade in a very limited way only. Nowadays the street lighting restores the day time appearance of the World Heritage Site more accurately than that at night because the modern lanterns produce more light than the original ones in order to meet a broad range of modern standards. The lighting of the streets and spaces of the World Heritage Site has a bearing on the authenticity and integrity of the Site beyond the physical form of the street lamps. Lighting position The positioning of the lighting plays a role in the way the streets are experienced. Every street is different in terms of scale, architectural character and function; however in the case of replacement street lighting, good conservation practice encourages identification of the original approach to a particular street, especially the type of overall design originally intended for the street such as the painting scheme, the type of lanterns and their position relative to adjacent architecture. In the Old Town, the general approach has been to illuminate the wider streets by means of high level lighting fixed to the buildings, with wall-mounted reproduction gas lanterns in the narrow closes and wynds . In the New Town, the general approach has been to use railing-mounted lamps comprising reproduction oil lanterns on standards made of mild steel (copying wrought iron originals) or (more authentically) cast iron. Reproduction gas lanterns have also been used in the lanes but lighting schemes using this type of lantern on pavement-mounted on standards are still being developed. Lighting schemes for streets of the New Town should take into consideration the relationship of the position of the lighting to building facades, especially palace frontages, which are one of the most distinctive architectural attributes of the New Town. Also it has to be emphasised that in the original streets railing mounted lighting did not add clutter and maintained long views, vistas and the surrounding architecture in contrast to standards placed on the pavement. Painting Initially dark grey was predominantly used in painting lamp standards (white lead oil paint loaded with carbon black pigment). This was superseded by dark green from around 1890 and a lighter shade of green from around 1920. In modern times this has been gradually replaced by gloss black everywhere in Edinburgh. Currently most of the street lighting as well as the railings in Edinburgh are painted in black and it would be rational to continue this approach, unless there are practical architectural set pieces where evidence of the original colour schemes can be found. The relatively good state of the conservation of the World Heritage Site is not currently followed by a similar state of conservation of the historic street lighting, as not much original material has survived. Only 30-40 original railing mounted lamp standards remain, of which about half have been re-used. In addition, no original lanterns have survived, apart from later gas examples. On the other hand, very effective lighting schemes have been created by using reproduction lanterns and standards. It is recommended that a strategic view be taken of this issue in order to improve the state of authenticity and integrity of the World Heritage Site by raising awareness on the importance of 32 appropriate maintenance of the historic street lighting in terms of appropriate repair and treatment. This is particularly important in the case of surviving original material. Krzysztof Jan Chuchra Edinburgh World Heritage August 2011 33 References: Boog Watson, C.
