The Angel's Way Route Seaton Sluice to Chester-Le-Street
Northern Saints Trails The Angel’s Way Seaton Sluice to Chester-le-Street 49 kms, 30.5 miles Introduction The Angel’s Way is an important link in the network of the Northern Saints Trails. This route between Seaton Sluice and Chester-le-Street means that there is a continuous 114 mile route between Lindisfarne and Durham, using St Oswald’s Way as far as Warkworth, The Way of the Sea from Warkworth to Seaton Sluice and after The Angel’s Way, Cuddy’s Corse (which is also part of The Way of Learning) from Chester-le-Street to Durham. All the Northern Saints Trails use the waymark shown here. In two parts, from near Holywell to Camperdown and from Bowes Railway Path to West Urpeth, the route follows The Tyne & Wear Heritage Way which is well signed and the waymark is also shown here. The route is divided into 4 sections, 3 of which are between 13 to 14 kilometres or 8 to 8.5 miles in length and section 3 from Millennium Bridge to The Angel of the North is just 8 kilometres or 5 miles. The route is of course named after the iconic Angel of the North designed by Antony Gormley. Since it was erected in 1998, it has quickly become Britain’s best known sculpture. When he designed the sculpture Gormley deliberately angled the wings 3.5 degrees forward to create what he described as “a sense of embrace”. This ties in with the protective concept of the guardian angel and if you want to engage with that theme as you journey on The Angel’s Way, perhaps this prayer will be appropriate: Angel of God, my guardian dear, to whom God’s love commits me here, ever this day, be at my side, to light and guard rule and guide. -

EDITORIAL The Society owes an apology to many of its members. Over the past year, a large number of Journals have failed to reach their destination, or have been delivered very late, to the understandable annoyance of the supposed recipients. This has caused a great deal of "hassle" and correspondence, especially with our overseas members, who ?R, r~.`rP h~P.T2.t~2p '72r3212.°3 .fPJRiS. ;'1 . ~ f ,•u~'tr ,`ueetl -rtlutrifrre$, ana'tne prdtilem should not recurAf you are a fully paid-up member, and have not received one or more Journals over the past year,please write to Mr R.

We are very sorry indeed about the failures, which have created serious administrative and financial difficulties for the Society. Each year since the Society was formed, an index to the Journals has been prepared by Mr Dave Linley of Preston, Lancashire. This is a necessary and invaluable work in a Society such as this. Mr Linley has now decided he has done a long enough stint. I can fully appreciate his feelings. Working unseen from a town away from the Society's heartland, Dave deserves all our thanks for his splendid efforts. But we now need a replacement! Here is a chance for non local members to help the Society. If anyone would like to take on the task of indexing from Volume 16, I would be glad to hear from them. -
Meeting Reports
AUGUST 2014 MEETING Speaker: Andrew Conacher Topic: Sir Humphry Davy – The Davy Lamp Andrew’s talk on Sir Humphry Davy was most engaging and enjoyable. He firstly spoke on Sir Humphry’s background and life and then focused on the Davy Lamp, its context and importance. Andrew indicated that he has an ancestral family connection to Sir Humphry. The following is a brief extract from Andrew’s paper. Sir Humphry was born on 17 December 1778 in Penzance, Cornwall, England and died 29 May 1829 in Geneva, Switzerland aged 50 years. A statue stands in Penzance with him holding his safety lamp. Andrew Conacher holds up miner’s safety lamps.

Flammable Gas Detection in Coal Mines – a Historical Perspective
FLAMMABLE GAS DETECTION IN COAL MINES – A HISTORICAL PERSPECTIVE Underground coal mines are dangerous places in which to work. This short article explores why, in part, this is so. It also provides conclusions that indicate how a study of one of the hazards encountered, namely flammable gas, and the associated control measures that were developed, may help reduce the risk to modern-day workers. These would not necessarily be coal miners, but workers in any enclosed environment where similar conditions could exist, e.g. tunnelling, confined spaces. It should be noted that the presence of flammable gas is only one of the hazards encountered in coal mines. Other significant hazards are associated with the industry, each with their own risks of death and injury. Naturally occurring hydrocarbon gases that appear in typically with deeper mines, the gas is trapped in the interstices underground coal mines have historically been given the of the coal, only to be released when the coal-bearing rocks are name “firedamp”, derived from the German word for vapour penetrated by tunnels.

1 Humphry Davy to John Davy, 15 October [1811] Davy, Collected Letters, Vol
1 Humphry Davy: Analogy, Priority, and the “true philosopher” Sharon Ruston Lancaster University, England https://orcid.org/0000-0002-3864-7382 This essay explores how Davy fashioned himself as, what he called in his poetry, a “true philosopher.” He defined the “true philosopher” as someone who eschewed monetary gain for his scientific work, preferring instead to give knowledge freely for the public good, and as someone working at a higher level than the mere experimentalist. Specifically, Davy presented himself as using the method of analogy to reach his discoveries and emphasised that he understood the “principle” behind his findings. He portrayed himself as one who perceived analogies because he had a wider perspective on the world than many others in his society. The poem in which he describes the “true philosopher” offers us Davy’s private view of this character; the essay then demonstrates how Davy attempted to depict his own character in this way during critical moments in his career. Introduction During the safety lamp controversy of 1815–1817, Humphry Davy deliberately presented himself as a natural philosopher. For Davy this meant someone with a wider purview than others, who is alive to the metaphorical, literary, and philosophical ramifications of his scientific discoveries. He represented himself as working at a highly theoretical level in the laboratory, rather than practically in the mine, making a clear distinction between himself and George Stephenson in this regard. Davy suggested that he was working for loftier ideals and was opposed to monetary gain or profit by patent. He declared that his discoveries were the product of analogical thinking and a consequence of his understanding of scientific principle. -

Safety Underground: Mining and the Miners' Lamp Transcript
Safety Underground: Mining and the Miners' Lamp Transcript Date: Monday, 1 June 2015 - 1:00PM Location: Museum of London 01 June 2015 Safety Underground: Mining and the Miners’ Lamp Professor Frank James Towards the end of this year we will be marking the bicentenary of the simultaneous, and almost certainly independent, inventions of versions of the miners’ safety lamp by Humphry Davy and George Stephenson, and in 2016 the anniversary of its first deployment. During the eighteenth century, the counties of Northumberland and Durham produced more coal than any other region in the British Isles. Even by the middle of the nineteenth century following the expansion of mining elsewhere, the north-east coal field still produced more than a fifth of the country’s coal. But such production came at a heavy cost to the lives of mineworkers. The opening years of the nineteenth century saw an exponential increase in coal mine fatalities caused by the explosion of what was then termed fire-damp, now known as methane (CH4). On 25 May 1812 ninety-two men and boys (including four aged under ten) were killed by an explosion at Felling colliery, near Gateshead. This was in the parish of Jarrow-with-Heworth, whose Rector, John Hodgson, was horrified at the loss of life, especially as virtually all the victims were buried in Heworth church. One result of this disaster was the formation, in the autumn of 1813, of ‘A Society for preventing Accidents in Coal-Mines’, generally known as the Sunderland Society. The formation of this Society had been prompted by the Durham born London lawyer James Wilkinson who happened to be present at the time of the Felling explosion and had been appalled at the length of the funeral cortège. -
Gas Testing Refresher
Passion to Inspire GAS TESTING REFRESHER GAS TESTING REFRESHER GAS TESTING REFRESHER Although there is a dispute to who invented the "first" miner's flame lamp that was safe to use in fiery mines. The success of the flame safety lamp was a culmination of the principles discovered by Dr. William R. Clanny, Sir Humphrey Davy, and George Stephenson. All three worked independently on the problem at about the same time, and all had some knowledge of the other's work. GAS TESTING REFRESHER The principle of isolating the flame of the lamp was evolved by Dr. Clanny in 1813. Clanny's first lamp designs involved enclosing the flame, and pressurizing the lamp via bellows that would use water reservoirs to isolate the flame. The lamp was rather clumsy, and saw no practical use in the mines. But the feature of a glass window would be later a common feature on safety lamps. GAS TESTING REFRESHER GAS TESTING REFRESHER Sir Humphrey Davy was performed several experiments of his own for the development of a safety lamp. In 1815, Davy discovered that if two vessels were filled with explosive gas, they might be connected together by a narrow tube, and the gas in one of the chambers could be exploded without transmitting the explosion to the adjoining chamber. This meant that a flame in a lamp, fed mine air through small orifices, would not ignite the surrounding air of the mine. GAS TESTING REFRESHER Davy's further experiments found that mesh-holes of fine metallic gauze acted the same way as narrow tubes. -

How Big Is a Hole?: the Problems of the Practical Application of Science
Trans. Newcomen Soc., 75 (2005), 175–227 How Big is a Hole?: The Problems of the Practical Application of Science in the Invention of the Miners’ Safety Lamp by Humphry Davy and George Stephenson in Late Regency England by Frank A.J.L. JAMES Presidential Address, read at the Royal Institution, London, 12 May 2004 INTRODUCTION An instance for Bacons spirit to behold — Davys magic lantern — The Miners Davy &c Every philosopher must view it as a mark of subjection set by Science in the strongest holds of nature.1 These are the notes used by the 25-year-old laboratory assistant at the Royal Institution, Michael Faraday (1791–1867), for his lecture to the City Philosophical Society2 on 16 July 1817 on carbon. They refer to the miners’ safety lamp invented by Humphry Davy (1778– 1829) towards the end of 1815. Since I first came across this passage, twenty years ago, I have always been fascinated by it. It can be subjected to multiple meanings and in the course of this paper I will tease some of them out. The quotation provides the text for the narrative that I want to explore in this paper, namely the link between science and technol- ogy. The idea that understanding the natural world through science gives humankind power to control the material world through technology goes back to Francis Bacon (1561–1626) in the late sixteenth century with his slogan ‘knowledge itself is power’3 and this, of course, is the first meaning that one can ascribe to Faraday’s text. Ever since Bacon there has been a significant strand in English thought of the benefits of applying science for practical purposes. -
Safety Lamp Controversy”: Davy Vs Stephenson in Letters to the Newcastle Press, 1816-17
Journal of Literature and Science Volume 9, No. 2 (2016) ISSN 1754-646X Andrew Lacey, “Rethinking the Distribution of Cultural Capital”: 1-18 Rethinking the Distribution of Cultural Capital in the “Safety Lamp Controversy”: Davy vs Stephenson in Letters to the Newcastle Press, 1816-17 Andrew Lacey A little over two hundred years ago, on 5 December 1815, a well-attended meeting of the members of the Literary and Philosophical Society of Newcastle upon Tyne took place. The purpose of this meeting, in the first city of the British coal trade, was to display several examples of the recent invention of the miners’ safety lamp. The various lamps presented were designed to provide a safe light in coal mines in the presence of “fire-damp”: the naturally occurring, highly flammable mixture of gases that would explode when exposed to a naked flame, and which, in the first years of the nineteenth century, had caused several horrific mining disasters below ground, such as that at Felling Colliery on 25 May 1812, when ninety-two miners were killed. A detailed, and sobering, record of mining fatalities in the north-eastern coalfield is provided by the Durham Mining Museum; their online database of colliery disasters speaks of the scale of the human tragedy that unfolded between 1800 and 1815, and thus of the pressing need for an effective means of risk reduction. Present at the Newcastle meeting was the botanist Nathaniel Winch, who sent a report of it, signed “N.,” to the Philosophical Magazine (James 223). Winch devotes a large section of his account to describing the lamp produced by George Stephenson, an “engine- wright at Killingworth Colliery,” before concluding: From what has been already said, together with the inclosed [sic] section, an invention nearly similar to Sir H.
