Over the recent season of political and social angst I’ve been finding solace in research and development work with my co-author George Walker. While our fellow countrymen argue the gray areas of morality and policy, George and I have immersed ourselves in the immutable truths that underlie the first principles of geometry. While there might be some gray areas in a few of the tradesmens’ layout shortcuts (which we explore at length along with the fundamentals in our forthcoming book “From Truths to Tools”), the core geometric constructions of reality that flow from the intersection of line and circle not only represent perfection – they are perfection.
For example, two intersecting circles that share a common radius will present us with two rim intersection points to which we can connect a line that automatically – and unequivocally – “bi secare” (cuts in two) the shared radius line.
The intersection of the lines at the bisection point form a “rectus” (right) angle with the radius line. We know it’s a right angle because the other angles are “co-rectus” with one another and any two of them form a straight line.
A further “proof” of the correctness of the four angles can be had by using dividers to “demetiri” (measure-out) between one circle’s focal point and a rim intersection point. This dimension will be exactly, precisely, perfectly the same at each of the other three point spans. This immutable truth provides us with the geometric construction we need to make a try square as well as the key to testing the tool for true. We now have in hand the ability to accurately lay out everything from a cradle to a coffer to a cathedral with little more than a bunch of sticks.

I take copyright and permissions protocols seriously. It’s a simple matter of the Golden Rule: I write and design stuff, and if someone’s going to use my words or designs, I’d like my part in the process to be acknowledged. I have no right to expect this consideration from others if I’m not willing to give it myself.
So I paid attention to what the museum staff told me when I visited the marvelous Wilson Museum in Cheltenham last winter to measure one of their Voysey chairs. I signed a bunch of forms agreeing to their terms, which require written permission to publish photographs of their holdings, even in a blog post.
In early July, as I neared completion of my manuscript for a book on English Arts and Crafts furniture*, I thought readers might be interested in seeing some of the details I found while peering under aprons, stretchers, and such in the course of my research – you know, stuff like through tenons, decorative gouging, and artfully chamfered rails…but also the occasional cupped table top, gap at a tenon shoulder, or split stile. It’s tempting to attribute perfection to our craftsperson-heroes, but one of the things I love most about furniture is its decidedly human imperfection; I’m intrigued by the question of what we’re willing (or not) to live with.
So I dutifully wrote to my museum contact, requesting the necessary permission.
“Dear Nancy,” he wrote back. “Thank you for your email. Permission would need to come from our decorative arts curator, however she is currently away from the office until [a date ten days later], so I will be unable to get a response to you before then. I shall pass your message on to [her] and bring it to her attention when she returns. I hope that this helps.
Best wishes,
B.”
Ten days later I received another missive. “Hi Nancy,” he wrote. “Thank you for your patience whilst the decorative arts curator was away. For using images of our collections in blog posts there is a small charge of £16.70 per article/blog post. We also request that you would send us a link to the blog post so we can have a record of how the collections are being used.
Please let me know if you are still interested in proceeding. If you are interested in proceeding please let me know and I will send the relevant forms and arrange payment.
I hope that this helps.
Best wishes,
B.”
I wrote back immediately. Of course I was happy to pay to use the images. Museums — especially those, such as The Wilson, which don’t charge visitors an entrance fee — depend on this kind of revenue. A few days later I received the form by email, which I completed and signed. A week went by. Then:
“Dear Nancy,
Apologies for not getting back to you… We are currently experiencing issues with our payment facilities so we cannot accept payment just yet. How soon do you need to use the images?
Many thanks for your patience whilst we are working on resolving the payment issues.
B.”
I told him that I wouldn’t need to use the images for at least the next three weeks. “Hopefully we shall have this rectified before 31st August,” he wrote back. I hated to think of a museum not being able to take credit card payments over the phone in this day when plastic is the coin of the realm.
A month later B wrote back. The problems were ongoing. “We can accept cheques if all else [should] fail, although I understand the postage from America would inflate the real price at your end.” It wasn’t the postage that troubled me, but the fee a bank would charge for any form of payment other than a credit card. I’d already called my bank. They no longer issue checks in foreign currency but said they could wire the money for a $50 fee. Screw that.
The next week the ever-charming (truly) B wrote again.
“Dear Nancy,
The cost…was £16.70 plus VAT so that would be £20.04 overall [about $27]. I have been talking to the finance department and they believe[] they have resolved the issue, they are checking one final thing and have assured me that we should be able to take card payment over the phone by Monday. I shall email you again on Monday with the hopefully happy news. Again, please accept my apologies for the ongoing delays.
Best wishes,
B.”
Just to be on the safe side I gave it a few more days. On Thursday morning I was ready to call. The landline seemed a better bet than a cell phone. I dialed the number but got a sound that clearly signified a problem. I repeated the process several times, omitting various prefix digits in case they were unnecessary. Still no joy. I called the phone company again.
“All calls to international numbers are blocked at present,” the clerk informed me. Can this really be happening? I wondered. It seems that fraudsters overseas have been calling US households and threatening the vulnerable among us with harm to their relatives if they don’t return the call and fork over thousands of dollars. “So you’re blocking ALL international calls because a few people have fallen for this kind of scam?” I asked. Apparently so. “Is this just you, or all phone companies? Because this seems like serious overkill. I am just trying to make a business call to England.” She couldn’t say whether our phone company was alone in taking this paternalistic tack.
“You can bypass the call block by using this code,” said the clerk, reading out a symbol and three numbers. I thanked her and tried the call again, this time with the code. The call dropped as soon as I dialed. I tried again. Same thing.
I called the phone company back. Another clerk this time; he said I’d have to make some kind of different arrangement, aside from the code, to call overseas. “I am trying really hard not to pepper your eardrum with expletives,” I answered, taking a deep breath. “I just want to make a simple business call to England. England! Not Nigeria. Not Myanmar. I just need to make a credit card payment to a museum. In the past, all I had to do was dial the number. I’m not willing to go through yet more steps. I’ll use my cell phone.”
So I dialed the museum’s number on my cell. The call was answered by a woman whose first language was clearly not English. “I need your name,” she said after the usual pleasantries. I stated my first name and she proceeded to type, reading the letters back – incorrectly. I corrected her, knowing that the charge would be declined by the credit company, were the merest detail garbled. Then we got to the address. Between the spotty quality of the audio (even with Wi Fi calling) and our linguistic disjunct, it was taking forever. We got through the four digits of the street address, but the word “South” caused a problem. “Was that ‘ah‘?” she checked. “No, SOUTH,” I said. At this point I was not prepared to attempt the Himalayan peak of the next word, “Garrison.”
“Can I just email you this information, then call back?” I asked.
“Sure. That would be good. Thank you.”
So I sent the email, and she replied that she was ready to take my credit card information in a second call. I called her back at once. The phone was answered by a machine informing me that no one was available but I could leave a message if I would like.
I checked the time. 4 p.m. GMT. Perhaps they had just closed? I wrote back to her straight away, dreading the prospect of having to repeat the process with someone new the next day. But lo! Five minutes later I got a reply. The long-suffering staff person had been busy with a visitor, and so, unable to take my call. I called back.
Miraculously, we get the job done. I have the receipt to prove it:
The receipt really does say JOY. Perhaps the name of a current exhibition?
All of which is to request that you refrain from blithely copying and reusing the images you will find in my post about the museum visit, which will arrive in your inbox a few days from now.
Please note: Although this post concerns one particular institution, I have enjoyed remarkably similar experiences with several others. I am a huge fan of The Wilson and highly recommend a visit.

Research for English Arts and Crafts Furniture: Projects and Techniques for the Modern Maker* has entailed some spirited conversations with scholars of medieval literature and art. My readings onmedieval European life without the benefit of Ruskin’s rose-tinted specs have touched on such seemingly unrelated subjects as church-based charity and prostitution in Paris.
So when I saw that St.John Starkie had posted a video on The Quiet Workshop about building a medieval pole lathe, I was intrigued. At a whopping 22 minutes and 41 seconds, it’s longer than your typical video in this day of Instagram hyperlapse, and (please don’t tell me you expected “but”) well worth watching. I found it visually mesmerizing as well as informative.
Minor mea culpa: However instructive the video component may be, my special guilty pleasure is the audio, which I find downright intoxicating. There’s something about the sounds of hand-tool woodworking when recorded through a mic that transports me into an alternate realm. It’s akin to lying in bed during a storm in someone else’s house: You can pull the covers up around you and sleep even more soundly than usual, comforted by your warm, safe situation. I’ve always found the equivalent storm experience far from soothing in my own house, where I worry that the roof might leak or be damaged by the wind. No wonder people who’ve never picked up a tool themselves wax romantic on the subject of making furniture for a living.–Nancy Hiller, author of Making Things Work

Job Centres were government-operated employment agencies intended to help people find gainful work instead of spending their days watching telly while sponging off the dole. At least, such was the image of their unemployed compatriots entertained by many supporters of Margaret Thatcher, prime minister at the time. Her cabinet ministers (well, some of them) were less dismissive regarding the plight of their jobless constituents. There were jobs out there, they insisted; you just had to put some effort into finding one. “Get on your bike” became an oft-heard exhortation after Norman Tebbit, Secretary of State for Employment, told attendees at the Conservative Party Conference in 1981 that he’d grown up in the 1930s with an unemployed father. “He didn’t riot,” Tebbit said; “he got on his bike and looked for work and he kept looking ‘til he found it.”
The Job Centre certainly made it more convenient to find employment. But I would have found a job with or without it. I was raised by parents who, despite the haziness of their hippie years, impressed on me the importance of hard work and self-reliance. At the same time, they also supported the provision of social services and safety nets, knowing that things can go wrong for anyone, despite diligent work and the best-laid plans.
My friend Beatrice, on the other hand, had graduated from Cambridge with a degree in drama. Finding herself unable to secure paid employment in her field, she didn’t hesitate to sign up for the dole. “But surely you could get a job at a sandwich shop, or cleaning houses?” I offered, shocked that this bright, resourceful, relatively well-off friend had sought government assistance.
“If I take a job unrelated to my area of expertise it will count against me the next time I apply at a theatre,” she explained over Lapsang Souchong in her cozy London flat. Seeing my stunned expression, she added that taking just any job “would suggest that I’m not serious about my profession.”–Excerpted from Making Things Work by Nancy Hiller
The three of you who pay close attention to my ramblings may recall that a couple of months ago, I wrote about the origin of the name sycamore, applied to both a kind of maple in Europe, and a kind of planetree in North America. The name supposedly refers to the shape of the leaves, and traces back to the sycomore fig (Ficus sycomorus). However, as far as I could determine, the sycomore fig’s leaves look nothing like those of either kind of sycamore. So what gives? I was determined to find out, so I booked a flight to South Africa [Truth-O-Meter:True] so that I could settle the question once and for all [Truth-O-Meter:Pants on Fire].
As it happened, I found a sycomore tree fairly quickly. This is the only one I saw that had fruit:
[Apologies for the poor image quality, but I only had my cell phone at the time, and the lighting was terrible.]
And, as various online sources suggest, the leaves look nothing like those of a sycamore (of either kind):
So, I have to go with my earlier hypothesis that somebody got a different kind of fig confused with the sycomore (possibly F. carica), and it’s really that other kind after which the sycamore (either kind) was named.
Having more or less resolved that issue, I decided to spend the next couple of weeks walking through the woods of South Africa [Truth-O-Meter:Mostly False]. In doing so, I faced some challenges: I know very little about the trees of South Africa, so I usually had no idea what I was looking at. And, it being winter, almost nothing was flowering. Add to that the fact that in most of South Africa, winter is also the dry season, which meant that many of the trees had lost their leaves. And did I mention that South Africa is mostly grassland? There just aren’t many trees to begin with.
Nevertheless, I soldiered on (all for you, dear reader). Fortunately, I did a lot of my woods-walking in national and regional parks, and many of the trees in these parks share a key characteristic that simplifies identification:
These signs were pretty neat, and something I hadn’t seen before: If you scan the QR code with your smartphone, it takes you to a web page with more information about the plant. (And yes, as you can guess from the scientific name, plants in this genus are the original source of the neurotoxin strychnine.)
But, like any product of modern technology, this one, too, has bugs:
The QR code on this sign does take you to a web page, but it’s the wrong one, for a different tree. Here’s what the tree itself (the right one, not the wrong) looks like:
Jackal-berries are in the genus Diospyros, which is the genus of both ebony and persimmon. Most Disopyros species are fairly small and therefore not commercially valuable, but nearly all of them have very hard wood, with the heartwood usually dark brown or black. The wood of these smaller trees is used for ornamental turnings and the like. The fruit looks a lot like a small persimmon:
(This one is a common jackal-berry, D. mespiliformis.)
Let’s officially begin our walk near the west coast, in the Northern Cape in an area known as Namaqualand (or, sometimes, the “succulent Karoo,” which is a pretty evocative name, if you ask me). Namaqualand is arid, not quite desert but close. There is very little rainfall, but some moisture does arrive from the Atlantic Ocean. There are virtually no trees, but like the deserts of the southwestern U.S. that are dominated by tree-like cacti, Namaqualand is also dominated by large succulents, only these are aloes, rather than cacti:
This one is the quiver tree, Aloe dichotoma. Although it appears substantial, the “trunk” is hollow and fibrous, resembling more a giant loofah than a log. The barren Namaqua landscape is punctuated by the desiccated skeletons of long-dead quiver trees:
As we travel eastward and inland, we move away from the ocean influence, and enter the Great Karoo:
There are still no trees (except along water courses), and the terrain and vegetation are strongly reminiscent of the Great Basin in North America. The few large trees that do exist are heavily (and I do mean heavily) utilized by Sociable Weavers (Philetairus socius):
The tree is an acacia of some kind, possibly sweet thorn (Vachellia karroo), but I’m not sure.
Even further east, we enter the Kalahari grasslands:
The Kalahari Desert itself is found mostly in Namibia and Botswana, extending just barely into South Africa, but the surrounding Kalahari Basin extends as far south as the city of Kimberley. This is still predominantly grassland, but you do begin to see small trees here and there. After spring rains, the area greens up quite a bit (this photo is from 2012, in December):
That meerkat (Suricata suricatta) was giving me a “Who are you and what are you doing in my front yard?” look.
Like other plants of arid regions around the world, nearly all of the shrubs and trees in the Kalahari are covered with thorns or spines:
This one is a common spike-thorn (Gymnosporia heterophylla). Its closest North American relatives are American bittersweet (Celastrus scandens) and eastern burningbush or wahoo (Euonymus atropurpureus), both vines.
Around the edges of the basin, you start to see “real” trees. This camelthorn acacia (Vachellia erioloba) was at Sandveld Nature Reserve, in Free State:
Like most other legumes, the wood is very hard and difficult to work. The “camel” in the name refers to giraffes, which use their long prehensile tongues to delicately pluck off the leaves from between the thorns of this and other acacias. In response to the browsing, the trees quickly begin to produce bitter tannin in the foliage, inducing the giraffe to move on to another plant. (Other trees, such as some oaks, respond similarly, but the acacia’s response is remarkably fast, on the order of five to ten minutes.)
As a rule, the many species of acacia have very similar foliage, so it’s difficult to tell one from another by looking at the leaves. But the flowers and especially the fruit are often very distinctive. The seed pods of the camelthorn are large and robust:
Moving south to the southern Indian Ocean coast, we find true forest, here at Tsitsikamma National Park, in Eastern Cape:
The dominant trees (by size, at least) in these coastal montane forests are Outeniqua yellowwood (Afrocarpus falcatus), and “true” yellowwood (Podocarpus latifolius). Both are botanically softwoods, in the family Podocarpaceae, distantly related to pines. The wood of true yellowwood is reasonably hard and has good workability, and so is prized for furniture and architectural millwork. Outeniqua yellowwood is softer and more likely to be found in utilitarian applications. The true yellowwood is also the national tree of South Africa.
These yellowwood logs (I don’t know which species) were in the process of being harvested after having been downed during a strong winter storm in 2008:
It’s hard to tell from the photo, but the logs are quite large, close to three feet in diameter.
As we continue up the coast to the east, the terrain becomes less mountainous. In isolated valleys, we find scarp forest, such as here at the Dlinza Forest Reserve in Eshowe:
This view is from an observation tower overlooking the forest. From the tower, we were able to get a treetop look at the fruit of a fig (F. thonningii) that is common in this forest:
If you look closely at the forest photo above, you can see what looks like a pom-pom on a stick on the horizon. This is a Natal cabbage-tree (Cussonia sphaerocephala). The scientific name means “spherical head.” Here’s another cabbage-tree, this one with multiple heads (the hydra of the cabbage-tree realm, it would seem):
The interior of the scarp forest looks not all that different from a temperate forest in North America, although the trees here grow more slowly and therefore tend to be more twisted and bent:
As is generally the case in areas colonized by Europeans, many of the plants and animals are named after familiar species that they resemble, even if in reality they are not closely related. Thus, we have this wild-poplar or false-poplar (Macaranga capensis):
With enough squinting, you can imagine that the leaves on this tree somewhat resemble those of an aspen or poplar. But the tree is actually in the spurge family Euphorbiaceae. Most spurges are shrubs or forbs, with a few species occurring in the southwestern U.S. The one species that most people are familiar with is the poinsettia (Euphorbia pulcherrima), native to Mexico. The wood of the false-poplar is said to be used for furniture, but I would personally be hesitant to work with it, as most spurges contain compounds that range from mildly irritating to, in the case of the castor bean, deadly poisonous.
The largest trees at Dlinza are the wild-plums (Harpephyllum caffrum):
For scale, the vine that hangs down in front of the tree is about twelve feet off the ground. As with the false-poplar, wild-plums are unrelated to what we call plums, and are in the sumac family Anacardiaceae, relatives of cashews, mangoes, and pistachios. Likewise, most members of this family contain toxic compounds. With sumacs, the toxin is urushiol, the active ingredient in poison oak/poison ivy. The wood is used for general-purpose construction, but is otherwise not notable.
The eastern corner of South Africa is home to lowland coastal forest:
One of the more common trees here is waterberry (Syzigium cordatum), a kind of myrtle:
I couldn’t find any information on the use of the wood, but the trees are fairly small and gnarly, so I suspect it has no widespread use. The berries (not present in winter) are apparently tasty.
The lowland forest in St. Lucia is also where we had an unexpectedly close encounter with a hippopotamus one evening. That’s a story for another time, but suffice to say that it was a Very Good Thing that we were standing in the adjacent parking lot, rather than walking in the woods, at the time.
Nearby, at Cape Vidal in iSimangaliso (“miracle and wonder”) Wetland Park, I found the only blooming woodland wildflower of the trip:
I have not the slightest idea what it is. It seems to have characteristics of both orchids and irises, which means that it might be a member of the order Asparagales. There are only about 36,000 species in that order….
Heading back northwards, we cross onto the Great Escarpment and the southern end of the Drakensberg (“mountain of dragons”). This is the beginning of the highveld (“high field”). The habitat is once again mostly grassland, but with pockets of woodland along the riparian corridors, such as here in Golden Gate Highlands National Park (in summer):
Near Johannesburg, the climate is drier, and the forest more sparse:
(Those odd-looking dark cylinders are another kind of aloe, A. marlothii.) Here, at Suikerbosrand (“sugarbush ridge”) Reserve, the trees once again become small and gnarly. The karee (Searsia lancea), another member of the sumac family, has hard wood that resembles yew and is likewise used for archery bows:
The buffalo thorn (Ziziphus mucronata) is in the buckthorn family Rhamnaceae:
The closest North American relative that I know of is Carolina buckthorn (Rhamnus caroliniana). My main reason for including this tree, however, is the Afrikaans name:
How can you not love a tree called “Blinkblaar-wag-’n-bietjie”? The name translates to “shiny-leafed wait-a-minute.” Other shrubs with recurved thorns, such as the catclaw acacia of Arizona (Senegalia greggii) also go by the name “wait-a-minute” or “wait-a-bit,” which comes from what people invariably say after getting tangled up by accidentally walking into one.
Finishing up in the northeastern corner of South Africa, we drop back off the Great Escarpment and enter the lowveld in Kruger National Park, extending from the province of Limpopo at the north end to Mpumalanga in the south. This is the southern limit of what we think of when we visualize the vast savannahs of eastern Africa. It is a mixed woodland/grassland habitat, with shrubs and small to medium-sized trees scattered throughout. In the far north we can find huge baobabs (Adansonia digitata), which are fairly uncommon in South Africa (they are much more common in Zimbabwe, Mozambique, and Tanzania, to the north and east):
This region is also the home of the only wood from the area that is commercially exported: African blackwood (Dalbergia melanoxylon). In South Africa, the climate is a little too dry, and blackwood (known locally by the Swahili name mpingo) grows as small, multi-trunked trees that are little more than large shrubs (much like eastern redbuds in the U.S.). You have to go further east into Mozambique and Tanzania before you find trees that are large enough for harvest. Much of the wood goes to the manufacture of clarinets, oboes, and other woodwind instruments.
A view from the Mlondozi picnic area near the Lower Sabie camp in Kruger gives an overall impression of the lowveld:
(For what it’s worth, according to Google Translate, the Zulu word “mlondozi” means “skin.”) The larger trees of the lowveld are nearly always located near water.
One common lowveld tree that anyone can remember is fever tree (Vachellia xanthophloea):
Its Grinch-colored bark is instantly recognizable. The fever tree was named by early European settlers, who noticed that the likelihood of contracting malaria was greater in the vicinity of the trees (which tend to grow in swampy areas harboring mosquitoes).
Traveling around Kruger, the most common large tree that I saw was Natal mahogany (Trichilia emetica):
Like African mahogany (Khaya), as well as sapele and sipo (Entandrophragma), Trichilia really is related to mahogany. The wood looks similar to those other species. While researching this species online I discovered that it is sometimes grown in a container as a houseplant.
Another common tree (also in the mahogany family Meliaceae) is cape-ash (Ekebergia capensis). The leaves do look a bit like those of ash:
The bark is different, though:
The bushwillows (Combretum sp.) are readily recognized by their four-winged samaras. This one is russet bushwillow (C. hereroense):
The only tree I found in full bloom was knob-thorn (Senegalia nigrescens):
The profusion of cream-colored flowers made these large trees easy to recognize from a distance. Other related legumes, identified once again by their seed pods, are the sicklebush (Dichrostachys cinerea):
and bullhorn acacia (Vachellia cornigera):
This lone seed pod in a leafless pod-mahogany tree (Afzelia quanzensis, not a true mahogany) illustrates the challenges I sometimes faced with identification:
I did eventually find one that still had a few leaves:
Afzelia is a genus of trees that wasn’t very well known to North American woodworkers until the publication of James Krenov’s Cabinetmaker’s Notebook trilogy. Relatives of this species from more tropical regions of Africa are the source of one of his favorite woods, doussie.
I found this Sansevieria (mother-in-law’s tongue) growing in the shade under some small trees. I believe that it is S. hyacinthoides (the common house plant is S. trifasciata).
That ends our whirlwind tour of the flora of South Africa (I skipped some parts). As always, I encourage you to find time to take a walk in your own woods. Keep your eyes and ears open; you never know what you might find:
I believe this is a marula tree (Sclerocarya birrea). To be honest, though, I wasn’t really focused on the tree at the time.
