  • Gunter’s Chains and Satellite Imagery: An Analysis of the 1775 Survey Plan at Uxbridge

    Gunter’s Chains and Satellite Imagery: An Analysis of the 1775 Survey Plan at Uxbridge

    Although I have been able to do a great deal of research from America, some portion of existing historical material simply isn’t available online. In the end, there is no substitute for time spent a fluorescent-lit archive amid a sea of box-laden shelves–or comparing notes with members of the local historical community.

    I was reminded of this truth while we were in Uxbridge recently. A member of the Uxbridge History Society shared a hand-drawn copy of a 1775 plan drawing from the Uxbridge Archives, and his own rare copy of a paper about the Treaty House by an accomplished modern historian. These two local documents provided a small trove of information that filled in a gaps in what I’ve been able to find–and one that disproved part of the model I’ve been developing of the original Treaty House structure. So, with thanks to Tony for sharing this information, I’ve been back at work on the Uxbridge Treaty House part of the Lane Project!

    Analysis of the 1775 Survey Plan

    Digging through materials related to the 1775 plan drawing at the Uxbridge Archives, I found that this document was a survey plan for the proposed straightening of the Oxford Road. This project, when completed, would irrevocably break up what remained of the original, proud property of “The Place”, two decades after the majority of the main house had been taken down.

    The 1775 survey plan document in Uxbridge is actually a photostat of a negative of the original document, which is likely located at the main London Archives. This plan was produced as part of an engineering survey of the site for the planned road project.

    This is an extraordinary artifact, as it is not a sketch or artist’s impression of the scene. Rather, it is an engineering drawing that includes a surveyor’s scale, and was thus intended to be as accurate as it could reasonably have been made. The graphic below was taken directly from the document at the Uxbridge Archives. The information it contains is singular. Most diagrams I’ve been able to find of this area do not contain this level of detail, and are from after the new road was already in place.

    This diagram was taken directly from a photograph of the 1775 survey plan from the Uxbridge Archives.

    There are several unique insights contained within this image. For instance, although I had read about an older “pack and prime” bridge that had been built in two segments over the Colne, I’d never seen an illustration of it. In the figure above, it is denoted as the “old” bridge. It also shows the footprints of the “Swan” alehouse and that of the remaining wing of the Treaty House (both of which still exist today).

    Despite the fact that the scene depicted is of the grounds decades after the main house had been taken down (and the property was already being sold off in parcels), many vestiges of the original grounds are still evident. For instance, the image clearly depicts the twin octagonal gatehouse (“lodges”) that flanked the original entrance to the property. Especially useful to me is the shape of the “old” Oxford Road as it arcs around the property. Before this document, I haven’t seen anything definitive about the shape of the original property. The wealth of other details (walls, fences, cultivated fields, ditches and buildings) provide a unique and satisfying view of “the neighborhood” around the Treaty House property at that time.

    There are several odd things about this image also. The Frays Stream (at right) is not a straight channel (as it is depicted), nor does it intersect the bridge and the town mill at the angle shown. Also, the gatehouses are placed at an odd geometry relative to the remaining Treaty House wing. as though the person drawing it didn’t realize that those structures were related. Prudent architectural sense would have placed the gatehouses parallel to, and centered upon, the original center span of the house. To get a better feel for what can be trusted in this image, I decided it was time to do some analysis!

    What is a Gunter’s Chain?

    A Gunter’s Chain. Image credit: Victorian Collection

    The text in the image refers to a “Gunter’s Chain” and provides a scale of 10 of these rulings in a line. A Gunter’s Chain was named after the English Clergyman and mathematician who introduced it in 1620, Edmund Gunter. It is a durable set of 100 links in a chain that is a total of 66 feet long, and is used exactly as we use a tape measure today–but for surveying.

    Having a surveyor’s scale in the image was simply too much for my inner nerd to pass up! First, leveraging the provided scale, I created a 2D “Gunter’s Chain” grid, which I laid over the survey image (see image above). Since each square in this grid represents 66 square feet, this grid can be used to make measurements on the image. Overlaying the 1775 survey drawing over modern satellite imagery of the same scene and using online distance measuring tools, I can use enduring elements in the scene to assess the accuracy of the original drawing.

    First, I had to confirm that the accuracy of the online distance measurement tools themselves. If the measurement errors were larger than what I am trying to determine, then there is little point in going any further! Using the “measure distance” feature of Google Earth and repeating a specific measurement of a significant distance (approximately 1,000 feet apart in the image) achieved results with a “standard deviation” of about 1.2 feet. This is good, as this amount of error includes any intrinsic error in Google’s measurement tool and also my ability to reliably choose the exact same spots to measure each time. Next, I measured the roof peak of the Treaty house multiple times, and consistently got measurements of +/-6 inches compared with measurements of the building I made while recently in Uxbridge. Bottom line? These tools are more than accurate enough for this job!

    Satellite imagery of the area around the Crown and Treaty, overlaid with the 1775 survey image. It was rotated to align the road in front of the Treaty House, and then scaled until the interior bridgeheads matched.

    I did not expect the survey map to be perfect. After all, it provides an overhead perspective drawn using only ground observations using 1600s technology. But I was pleasantly surprised how well the survey image laid onto key parts of this scene. In particular, the spatial relationship between the new roadbed and the bridgeheads at either end of it was nearly perfect. Also, the surveyed distance from one bridgehead to the other was 11 “chains” (726 feet). This matched satellite measurements (705 feet) of the same distance fairly well (given that I did not have clear visual targets for making this measurement).

    But there were also some unexpected misalignments (see the analysis graphic above). The depicted footprints of the Treaty House and the Swan are both misplaced by at least 20 feet (in different directions), and both are somewhat rotated from their true orientations. Also, the twin gatehouses are depicted significantly closer to the new road bed than the “52 yards” the roadbed was (separately) recorded to have been moved.

    The explanation for the variation in accuracy is that certain parts of the scene were carefully surveyed, while others seem to have been drawn in for completeness. If you look closely at the plan, you will notice a grouping of 5 points called out near the Colne bridgehead (labelled A, B, C, D and E). These are specific survey points that surround the planned roadbed where it approaches the new bridgehead. In fact, the text on the plan calls out how much fill dirt would be needed to fill in this part of the road. It also makes sense that the width of the island was more accurately measured, as the length of this section of new road would have been a key metric for the project.

    But those areas which lay outside the new roadbed were not directly relevant to building the new road. These details were made for completeness of the scene, and it appears were less accurately captured by the engineer that created this plan. The next graphic of the scene summarizes which regions of this diagram I was able to validate as accurate, and others that are either suspect, or were revealed to be inaccurate.

    Dr. Richard Spence’s Article on “The Place”

    The second important artifact I obtained in Uxbridge was a paper published in the Autumn 1994 edition of The Uxbridge Record (by the Uxbridge History Society). This is an excellent paper about the early history of “The Place” (as the Treaty House property was originally known) and those who built and later owned it.

    I was surprised to learn that the author, Dr. Spence, was not a local resident–he was from Leeds, far to the north. Like myself, Dr. Spence’s attention seems to have been drawn to Uxbridge by a thread of his primary research focus. After losing his role as a Senior Lecturer at Leeds and Carnegie College during a educational consolidation at age 54, Dr. Spence retired early and threw himself into the topic of his original PhD thesis: the history of the Clifford family (Earls of Cumberland). He authored several books regarding the Cliffords and several places related to the family.

    The thread that seems to have brought Dr. Spence to the Treaty House was the granddaughter of Dr John Hughes, who originally built “The Place” in ca 1535. In her adulthood, this daughter (Grissell) married a man named Francis Clifford. The newly married couple first lived at “The Place” while Francis was constructing a bold new home amidst the rest of the Clifford family in Londonborough. Some years later, Francis succeeded his brother and became the next Earl of Cumberland. Lady Grissell (daughter of Uxbridge and raised at “The Place”) was now a countess.

    Apparently pursuing this marital link between the Cliffords and Uxbridge, Dr. Spence became interested in the Treaty House and wrote his excellent paper on it in 1994. This paper was a privilege to read. I would have loved to have met Dr. Spence, but he died in 1999–5 years after making this unique contribution to Uxbridge history. The Guardian news site has a wonderful online obituary that describes him (Richard Turfitt Spence) as a warm, gentle and witty historian and an avid club cricketer. I was able to find 6 books he published, most available on Amazon. Unfortunately, I was unable to find a photograph of him, or I would have included it. So, with a salute for excellent, singular work and the significant help it has provided me–many thanks, Dr. Spence, and rest well.

    For my work, there were several worthwhile discoveries in the Spence paper. First, while Lady Grissell and her husband Frances Clifford were living at The Place, arrangements were made to receive a visit there by Queen Elizabeth I (and her retinue) in October 1592. His description of the effort undertaken was fascinating, although Dr. Spence tells it is not clear the visit actually happened. Recall that this royal visit would have taken place only a few years after the Elizabeth I had so capably led the defense of England from the invading armada of King Phillip II of Spain in 1588. For Americans who aren’t familiar with this, watch the academy award-winning movie, Elizabeth: The Golden Age (2007)–it was Elizabeth I’s “Churchill” moment. She was at the height of her power, and her reign was an era of prosperity and relative stability compared with the chaos and religious whip-sawing of the country by King Henry VIII and his immediate successors. I suspect if this royal visit had actually taken place, it would have been an important local event that would have become part of the fabric of the property. The additional notoriety might even have saved the estate from its ultimate fate…

    A few years after Francis Clifford and Lady Grissell had moved to their new mansion at the Clifford family seat in Londonborough, the Uxbridge property was sold to Sir John Bennett in 1613. Apparently, the new Earl Francis Clifford had inherited significant debt along with his new title, and the sale of “The Place” was necessary to help resolve them.

    Sir John Bennett was already a significant landholder in the area who desired a convenient and enviable estate commensurate with his status. Sir John undertook the first great renovation and improvement of the property in 1623. As part of this costly expansion, the attic areas of both wings were built out to provide additional accommodations for his 10 children, 40 grandchildren, servants and guests.

    Dr. Spence tells that the original chimney structures contained a single flue in each turret. But as hearths were added to heat the new rooms in the attic spaces, additional flues for them were carefully fitted into the center turrets of the chimney structures. Additionally, Dr. Spence notes there may have been a revamping of an original “great hall” in the center span of the building. This update (which likely also included the fitting of the famous carved paneling) would have created the elegant spaces utilized during the treaty negotiations in 1645. With the completion of this work, the significantly upgraded property took on a new name, becoming known long after Sir John’s death as the “Bennett House”.

    There was one important detail in the paper I need to disagree with. Dr. Spence about. He speculates that the “good stairs” described to be at both ends of the center span’s main chamber were contained in angle turrets (as exists at the far end of the building today). However, that octagonal structure is not present in depictions of the building from the post demolition period of the latter 1700s. Although quite functional (having used them), it’s difficult to imagine anyone remarking upon them as “good stairs”. But most telling is the presence of filled-in windows in the end wall of the building which are unaligned with floors. These windows are clear evidence that an elegant stairwell was originally located within the end of the existing wing.

    Reviewing the brickwork that connects the octagonal structure to the far end of the building (and various images of the building over time), my own suspicion is that it was added sometime during the middle 1800s when the Treaty House (and the large building appended to its backside) served as an Inn.

    Finally, I was amused to read Dr. Spence’s mention of a “hearth tax” of 20 hearths on the property in 1674. This caused me to smile because the three chimney structures of the existing wing alone contain 12 flues. If the opposite wing was symmetrical, there would have been 24 flues before even considering those needed to heat the large center section of the building! My current model estimates there were an additional 2 flues at each end of the center span of the house and at least 2 full sets of chimney stacks along its back wall. This would have resulted in a total of around 34 hearths in the house at the time this tax was assessed. Apparently, tax dodging is a very old game indeed!

    Layout of the Original Treaty House

    A sketch from DR. Spence’s paper showing how he believed the original Treaty House was laid out.

    Dr Spence’s paper includes a sketch of what the original structure might have looked like. Apparently, Dr Spence shared my suspicion that the spatial relationship of the remaining wing and the gatehouses depicted in the 1775 survey plan was not fully accurate. As Dr. Spence has illustrated, it is far more likely the twin gatehouses would have been centered on the house and arranged parallel to the face of the center span.

    In my next article, I will share the the resolution of some nagging incongruities with the simple layout depicted above. There is more to know about how the wings actually attached to the center span. The clues lie in the tortured walls at the far end of the remaining structure…

    For the last few years, Mary and I have been discussing the possibility of an extended visit to the UK that would allow me to do some much needed in-person research for this project. With the wind-down of the pandemic and the passing of a much loved, furry member of our family last year, we have decided it’s time.

    We are both excited and nervous, of course. Its already hard to think about being away from our friends and family for an extended period, but this is something we don’t want to look back on later and regret not doing when we could still do it well. Having made new friends in Uxbridge, we are very grateful we will have a community to make our own for awhile. It will be wonderful to do simple things like making meals together!

    Of course, we plan on making the most of the opportunity for adventure, and are bringing our road bikes and hiking poles. We are looking forward to exploring a great deal of England, Scotland and Ireland (and our most yearned-for places in Europe) in our down time!

    For now, we still have quite a few arrangements to make, including finding a fill-in drummer for my band. Regarding my research, I am filling out my list of topics I haven’t been able to run to ground from America. I will also have to decide which books I will really need to have with me. But by this fall, I hope to be putting in some quality time in the archives of London, Oxford, Northampton and Somerset. And making time to meet with some acquaintances we’d enjoy seeing again–especially without having to rush the visit this time!

  • The Other Jewels of Uxbridge

    The Other Jewels of Uxbridge

    We landed back home yesterday from our trip to Uxbridge, which lies on the western outskirts of London. We are grateful that everything came out so well–much better than we might have expected. The talks and the unveiling were well attended, and we found some important new historical resources available only at the local archives.

    But our fondest takeaway was some of the people we met while we were in Uxbridge. More than once I had the disorienting experience of spending time in the easy company of folks who felt like old friends–though we’d only just met. And more than once, I found myself very much admiring their own splendid works. To be so welcomed and engaged by such quality people was a joy. It made our trip truly wonderful.

    At Our Lady of Lourdes and St. Michael

    The day after we landed, we attended Sunday Mass at Our Lady of Lourdes and St. Michael Catholic Church. The parish priest, Fr. Nick Schofield, would be our host for the first talk, scheduled for the following evening in the church hall. Mary and I agreed the feel of this church was “quietly vibrant”. The congregation was of all ages, including lots of young children. Fr. Nick’s sermon was about bereavement and a perspective on living your life “while it’s fizzy”. It was brilliant! He also pointed something out I’ve never been able to put my finger on. He said part of what is so hard about losing someone you are close to is that you also lose who you were to them

    The church has a book near the altar where people can write the names of their lost loved ones. During the service Fr. Nick also read aloud names folks had given him for that same purpose. We later learned that Angela, his assistant (and author of some of his best lines) is also a bereavement counselor, so this healing focus is no accident. My overall impression was that Fr. Nick and Angela have made this church a genuine haven of faith, kindness, strength, solace and wisdom for the people it serves. I really don’t know how you could do better than that.

    A group of us had a great time walking up to the Crown and Treaty for lunch. From the left: me, Nick, Mary, Angela, Bill, Maria and Gabriella.

    After a tour of the church, and being introduced to a number of parishioners, a group of us went for a chatty walk up to the Crown and Treaty for lunch (and another look around). I think my favorite part of it was hearing how Fr. Nick conducted the special catholic service at the Shrine of King Edward “the Confessor” (which lies at the very heart of Westminster Abbey). This was a request made by King (now Saint) Edward that has been honored since his time. Recall that Westminster Abbey was taken over by King Henry VIII when the Church of England was formed specifically to break away from the control of Rome, so this inclusion of catholicism is a tradition not everyone is happy about.

    At St. Margaret’s Church

    St. Margaret’s is an Anglican church, and one of the oldest buildings in Uxbridge. Some form of it has stood at its location on the edge of High Street since the 1000’s. It is a beautiful old church that has been built up over the centuries. Vicar Andrew is good friends with Nick and Angela, and attended the first talk on Monday. At that talk, he offered to host us for a tour of St. Margaret’s and lunch on Friday–of course we said yes!

    Along with Nick and Angela, Vicar Andrew is one of my new favorite people. With a graciously warm style, he is a pleasure to talk with. While at lunch our table was raucous with laughter and back and forth chatting. Like Nick and Angela, Andrew is a man of considerable depth. He has spent a lot of time in the middle east, and served in a special role as liaison with the leaders of other faiths, including shia Ayatollahs. I trust so little of the information we get through today’s media. This made it a high voltage experience to hear the perspectives of someone who has first hand experience respectfully interacting with sometimes prickly members of these other faiths and cultures.

    Like Nick and Angela, Vicar Andrew is truly his brother’s keeper. While we were having tea and biscuits in the church, I asked about people I noticed coming in, and found out the church supports a minor food bank for folks who might otherwise not be able to eat. Nothing out of the ordinary for them–just another thread in the fabric they have woven in Uxbridge. In a world overrun with influencers and the selfishly inclined, this kind of softly spoken leadership and moral service to the community was humbling and inspiring.

    At the Hillingdon Archives

    Another individual we were fortunate to meet was Paul Davidson, a collections officer at the Hillingdon Archives. On Monday night, we learned of an important historic document that was a particularly relevant source of information regarding the grounds and layout of the original treaty house. Unfortunately, by the time we were able to get to the archives, we would normally not have been able to see it (the archives are only open by appointment on Wednesdays and every other Saturday). Although a busy fellow, Paul took time to come down and talk to us for a few minutes about what we needed. Seeing that this information would affect my upcoming talk, Paul squeezed us in later that day.

    Mary broke away early from our meeting with Roddy to make the appointment at the archives. By the time I was able to join them, she was steadily working her way through photographing several boxes of artifacts related to the Treaty House. It will take some time to work our way through it all now that we are home again!

    Best of all, the key document we were hoping for was there–a photo negative of a plan map of the roads and principal buildings between the Rivers Colne and the Frays from 1775. Although the original house had been demolished several decades before this document was made, it was entirely credible, and had been made within living memory of the original house. It was exactly the source I had been so far unable to find. I look forward to analyzing it, including overlaying it onto satellite imagery to refine my graphics of the grounds, and to update the orientation of the Treaty House itself.

    While we were there, Paul showed us a couple of special treasures of the archives, including a fascinating large bound book of source materials for the “Redford and Riches” history of Uxbridge. It was an archive unto itself, filled with source materials. I have a copy of the published result in my own library. Paul also showed us the license for the market in downtown Uxbridge. I believe he indicated it was at least 900 years old…

    It seems we needed to come to Uxbridge to find this critical information. My deepest thanks, Paul, for the grace to help us avoid leaving without it.

    At the Crown and Treaty

    The day we landed felt like a day from the Twilight Zone–but in a good way. After we dropped the artworks off with the folks at Croxley Galleries (who did a splendid job with the framing, btw), we stopped by the Crown and Treaty to finally meet Sam, the General Manager there.

    You have to understand, I have studied this building and its history for 5 years without ever being inside it. Walking in for the first time, I felt like I was going to overload from absorbing details about the place. My attention was flashing all over, trying to look through the building’s present state to find those enduring artifacts of its original form. And just as the dizzy was fading, Sam walked up and introduced himself.

    Sam and I don’t go way back–only to June of this year. Starting with a email exchange, we realized we had a shared interest in making the early history of the Treaty House more tangible to its modern visitors. We decided to see if we could make it happen. And now, 5 months later, we found ourselves facing one another for the first time. It was novel seeing him in the flesh, but it took only a few moments to acclimate to the familiar Sam I’d been working with for months. And we began working together as fluidly as we had been online. In the end, we got it all done.

    Sam and his staff were wonderful hosts to us. We were given license to measure, photograph, poke and prod as needed to understand the details of the building. Access was even arranged to see important aspects of the non-public areas of the building including a peek into the attic for a look at the roof structure. We got to know the staff, and were always greeted with a smile and a warm “hello”. Being greeted with such hospitality really made it worth all the effort and expense that went into this project–for us, and also for the artist, Rhonda, who travelled to the UK to be part of the event as well.

    I always assumed we would need to make an update to the piece we’d developed. And we do. Perhaps when that work is done, we may travel back to the UK for a chance to see this public window into the Treaty House’s proud history finalized. It would be a great excuse to see Sam and our other new friends in Uxbridge again.

    My first meeting with a relative of Sir Richard Lane

    Roddy Lane and I have been in intermittent contact for a long time. Roddy has inherited a significant geneology study of the various Lane families of England from his father. It is quite an accomplishment, and is quite well organized.

    I was delighted to learn that Roddy would be able to come to Uxbridge to meet with me. I was even more grateful when I learned he was making a 2-1/2 hour journey to do so!

    This is Roddy Lane, from Kent. He is a descendant of the family of Sir Richard Lane.

    Once I get through the Treaty House project and return to my primary research on Sir Richard Lane, I intend to start by focusing on comprehending the work Roddy and his father have done. I would very much like better understand the relatives and close family friends of the Lanes to see if I can locate any other surviving artifacts of his life.

    Roddy is a delightful person, and someone I felt a lot in common with (including skiing in Colorado). I regret that we didn’t have more time to talk, as I enjoyed his company immensely.

    The Battle of Britain Bunker

    Remembrance Day brings me to one last “jewel” of Uxbridge. This one is not about anyone we met, but rather about people I have always admired: Winston Churchill, the architects of the “island nation’s” defense, the soldiers and airmen who fought the battles, and the heroic grit of the ordinary people who persevered through them. Together, they “fought like Ukrainians” when Hitler attempted the subjugation of England, and smashed his vaunted Luftwaffe against the wall of English ingenuity and resolve.

    Certainly, I knew of this control center, but I didn’t realize it was in Uxbridge. It was fascinating to see it for myself, and to learn more about the famous “Dowding System” used for coordinating the air defenses. There was a moment when every squadron that was airworthy was engaged in repelling an especially large attack. Truly heroic. Later, when we stopped to talk with a gentleman handing out remembrance poppy pins for donations, we gladly handed over a note for two of them.

    The next articles will be about the talks themselves, and the study of the new material we have.

    When her kids were young, Mary lived in Haselmere, in Surrey. The special friendship which developed with these neighbors over 30 years ago still thrives today. I first met them when we were in the UK in 2018. We drove down to see them again this past week.

    Our friends in Haselmere. From the left: me, William (who served in a combined unit with the American 82nd Airborne), Mary, Carole and Sandie. Peter was away, unfortunately.

    The sensation I experienced among our new friends in Uxbridge was repeated here–in the easy, genuine company of people we are blessed to have as our friends.
