Blacksmithing

 

In movies blacksmiths look like WWF wrestlers, dramatically slamming white-hot metal with sledgehammers. When I took a blacksmithing course under the guidance of an old pro, the experience was more realistic: A plate-sized fire, small tools and frantic tapping.

The forge this time was an old metal hubcap, with small holes drilled in the middle, and the blower was a refurbished Electrolux vacuum motor. You don’t even need the electricity; on another course we sculpted a forge out of clay and horse manure, and turned some old fertiliser bags into bellows.

We began each day by lighting a small fire in the middle of the hubcap, right over the holes. Once the fire was going, we placed charcoal delicately over it, and then a ring of coal around the charcoal, and the crank fan blew air through the middle to keep the fire hot. Iron-working only appeared in the last 5,000 years or so – the final 0.3 percent of the time humans have had fire – because ordinary wood fire does not heat iron enough to work, and large amounts of charcoal and air are needed.

We quickly learned that you need to spend a great deal of time standing over the fire, with the metal part in just the right place – in the middle, above the blower and slightly buried in charcoal – to get the right temperature. Too little heat, of course, and the metal cannot be worked, but too much and it begins to “burn,” liquefying and sparking. A lot depends on the size of the metal piece – the tractor axel we put in took ages to heat, but I accidentally burned off the tines of my fork in short order.

Once the metal was glowing orange, we had to rapidly move it to the anvil without yanking it out and sending hot coals everywhere, and without burning the people standing shoulder-to-shoulder with you. Once at the anvil you had only several seconds of BAMBAMBAMBAMBAMBAM ... until it was black and solid again.

Also useful are steel vices and hefty pliers, which allowed us to grip metal while turning it – hence the twist in the fork handle. None of us wore gloves, but leather aprons and goggles were recommended against flying sparks and coals.

This time, I took an old car part and hammered it into a straight bar, flattened it into a knife-shape over the next two days, and a bit of cutting and polishing did the rest. I cut a handle from a hazel branch, heated the “handle end” of the metal until it was yellow-hot, and seared the hot metal into the handle, with a gust of steam and a few bursts of flame from the wood.

Blacksmithing is one of the dozens of professions that were widespread until just the last century, now is kept alive only by a few aficionados. For thousands of years in metalworking cultures, smiths were a vital and respected role – look how common it is as a surname today. They might become vital again if the coming decades bring the turmoil we anticipate. With charcoal and tools, a smith could turn landfill scrap and old car parts into useful tools again – and as far as I know, there is no end to the number of times metal can be recycled.

When the world is no longer able to mass-produce new materials at its former rate, when there is no new plastic and fewer forests, we will have billions of tons of landfill waste. Movies like WALL-E posit garbage covering the Earth, but in real life much of that garbage would not only be reusable, but precious. Some of it will be metal, and all the landfills we have created in the last few decades could become our mines in the next few decades.

Making Butter

 

Milk is not only an amazing food, but can be made into many other foods as well – butter, ghee, kefir, yoghurt and thousands of kinds of cheese – and all of them can be made at home. We are fortunate to be able to use them; in many parts of the world, people cannot digest milk products, so they tend to be found mostly in Europe, and occasionally in India or the Middle East.

Butter was deeply important in this part of the world; for dairying peoples it was the most accessible form of oil, needed for cooking food and releasing the extra nutrition. Back when people milked their own cows and goats, they made their own butter with a churn, but you can do the same thing with a screw-top glass jar or some other sealable container.

First fill the jar one-quarter to one-third full of cream – a greater proportion than that and it won’t work.  People in times past would use whole, un-homogenized milk, but that’s difficult to find these days, so cream is a good place to start. 

The next step is to shake the jar vigorously for perhaps 20 minutes ; try putting on some dance music and giving yourself an aerobic workout, jumping around the house shaking the jar all the while. Don’t worry if it takes more or less, as it will be fairly clear when butter forms inside . At first the cream will become, effectively, whipped cream, and if the jar is more than third full you never get enough agitation to get past this stage. Eventually, though, you should see the liquid become thin again inside, with a clump of something in the middle. That clump is your butter, and the liquid is buttermilk.

To separate them, place a strainer over a bowl, unscrew the jar and dump the contents into the strainer. You can drink the buttermilk or use it for making pancakes or any number of other uses – it should keep for at least a week. The butter you can lift out and put in a bowl to sweat.

By “sweat” I don’t mean making it hot; in fact, you could put a few ice cubes in with the butter to keep it cool. It means that you have to chop, press, squeeze and knead the last of the watery buttermilk out of the butter, so that it will not go rancid. As in a party game, you must do this with spoons, touching the butter as little as possible with your hands – the warmth of your body could melt the butter. 

When you are sure the last bit of liquid has been squeezed out, you have butter. If you like you could use it this way, as Europeans do, or add salt as English and Irish do to preserve it longer. You could mix in chopped herbs, like parsley and chives, to spread on bread, or sage, garlic and rosemary to bake a chicken. Use your imagination.

In warmer countries – or in Ireland in warmer weather – butter will not keep long in the heat, so before refrigeration Europeans used clarified butter, and Indians developed ghee. Ghee is essentially spiced clarified butter, and while there are many variations, you can make a simple version at home. 

First put your butter in a pan on the stove on very low heat – I put a thin metal plate on our gas stove, and the pan on top of that, just to dissipate the heat a bit more. The butter will quickly melt and begin bubbling, which is good – but be very careful not to let it darken.

The butter should separate into three layers; a white film on top, the oil layer that is most of the butter, and the milk remains on the bottom. Only the middle layer is what you want. Early on you can spoon off the milky bits on top, and spread them on bread if you like. After that you can add spices, like bay leaves or fenugreek seeds, as the Indians do.

Keep it on very low heat for half-an-hour to an hour, checking frequently – again, it might take more or less for you. When there is no more bubbling or hissing, just the oil and the milk deposits at the bottom, you can strain it through a tea strainer and stop when you get to the milk deposits. The milk deposits, browned at this point, are still edible, and are good on popcorn. The rest should be a clear, golden-brown oil that will keep for months without refrigeration.

Or, you could bury it in a bog if you have one nearby, as I’ve covered here:

Thatched roofs


Most of us take for granted that we will spend most of our lives paying off other people that we paid to build our homes, yet until historically yesterday people made their own homes. They built with wattle-and-daub, cob, with squares of turf, with stones, bricks or planks of wood, using whatever they had; everyone knew a carpenter or mason, John Curran remembered, and they pooled their resources, and houses, farm buildings, and stonewalls were constructed when required.”

Some of those building materials could be superior to what we use today. In rural Ireland I once helped sculpt a house out of cob, a wet mix of sand, clay and straw that holds together like concrete, and can be far more durable. The house began with stone walls that went up to waist height, as cob needs to be raised above the damp. Then we heaped the wet cob mix on top of the stone walls one lump at a time – “cob” is from an Old English word for “lump” – and then trod them down in our bare feet. Bit by bit, the walls got higher, until we could lay a roof on top. After the walls are given a plaster finish, the house can look just like any other, but made at a fraction of the cost, as it uses the simplest and cheapest material on Earth -- earth itself. Despite this, they can last hundreds of years; Sir Walter Raleigh’s palatial mansion was built of cob, and still stands after 500 years.

Many farmers in my native USA make homes out of straw bales, which are as fire-resistant as wood and which are superb insulators. Here, though, straw was put to other uses.

“Ninety-five percent of the houses at that time were thatched, and I can tell you they were warm comfortable houses,” John Lydon remembered. “The fireplace was almost as wide as the house, and there was always a huge turf-fire blazing in the centre, which drove heat all over the kitchen. 

The straw from a thatched roof was free from the fields; some roofs even had scarecrows to keep birds from stealing bits for their nests. Local saplings were cut, bent and tucked into place to secure the straw so tightly that the fiercest winds couldn’t dislodge it. Nor, in this damp climate, was it a fire hazard. The roofs lasted several years until moss started growing over the straw, staining the rain green as it streaked down the white sides of the cottages.

Thatchers were “usually lithe and agile to facilitate climbing on roofs that were often fragile,” Joe Keane said. “He chose his materials with great care to ensure durability against harsh winters. The thatched roofs of Irish cottages were aesthetically pleasing and ecologically sustainable.”

“The old-time thatchers could turn their skills with straw to other areas, and one of these was apparently the weaving of mattresses which were said to be of such quality that they would last for years: some of them had even mastered the difficult art of making conical ‘bee skeps’ out of straw,” Maurice McAleese said. “When a thatcher succeeded in weaving a skep he could consider himself as being at the head of his trade.”

Even if you don’t want a thatched roof, you could make a green roof. Cultivating plants on your roof creates a patch of natural habitat, partially replacing what was destroyed to create the building in the first place. They provide food for bees and other miniature helpers who will fertilise your garden. They help insulate your home, which can spare you heating and cooling costs. Finally, they look brilliant.

To create one people generally cover an ordinary roof with some kind of lightweight plastic, like pool liner, and spread thin but fertile soil on top of that. The soil should be laced with grass and other seeds, and over the soil should stretch fleece to stop erosion until the plants grow.

These roofs do not have to just carry grass, which is one of the hardiest of plants. They could carry wildflowers as well, which would create a striking cover for your home as well as fodder for insects. I urban tenants who are even using their roofs for beehives, allowing the bees to pollinate urban gardens while allowing them to steer clear of passing humans. If you grow hanging plants like nasturtiums, you could even have the plants hang over the sides of your roof, creating awnings and shaded walkways in the seasons you need them most.

Meadowsweet

 

Every late summer the boglands and canal-banks of County Kildare erupt in creamy-yellow tufts of meadowsweet, filling the breeze with their sweet scent. For centuries it was used as a painkiller, as it contains salicylic acid, the basis of aspirin – in fact, its Latin name Spiraea is how we got the word “aspirin.” Irish also used its strong aroma to freshen their houses, as well as to flavour mead – the name means “mead sweet.”

Unlike some wildflowers, meadowsweet are in no danger of going extinct, and have only multiplied with human activity. It grows along roadsides, but don’t pick it from there – you don’t want the chemicals from the car exhaust.

Meadowsweet makes a good tea, slightly astringent and very aromatic. You can also pick 20 or so meadowsweet flowers to make a sweet cordial, which can be kept for years and used to flavour drinks or in cooking. Heat 750 ml of water and stir in 400g of sugar and 20 ml of lemon juice. Bring to a boil and add the meadowsweet, then turn off the heat and wait about 10 minutes before straining the liquid. Let it cool and store in the refrigerator.

Most of all, meadowsweet makes a delicious dry wine. These days, for many Westerners, “wine” refers only to grape wine, but you can make wine and beer from almost any edible plant and some inedible ones.  Turning water into wine – literally – could be a matter of life and death for most of human history. Water could be contaminated with any number of diseases, but adding vegetable matter and yeast allowed the yeast to multiply and take over, releasing enough alcohol to discourage any other life in the water.

Making the wine is similar to making the cordial, with the addition of yeast and time. Pour six litres of water into a large pot, and bring it to a boil. Then dump in two litres of meadowsweet tufts. Squeeze in the juice of two lemons, boil it again, and turn the heat off – I also put in the zest of the lemons to make it a bit tarter. 

Stir in a kilogram of sugar slowly until it dissolves, and waited for the liquid to cool to blood temperature. Then pour it into a cleaned and sterilised bucket and add wine yeast – although bread yeast will do in a pinch -- and cover the bucket and set it in the closet. 

Over the next week check the bucket periodically; it should be bubbling away slowly as the yeast turns sugar into alcohol and carbon dioxide. After a week or so, sterilise a carboy – a large jug with an S-shaped valve on the top – and strain the wine into it; I use a paper coffee filter to strain it into a large glass, and then pour it through a funnel into the carboy. Carboys let you store wine during the weeks or months that it still might build up some air pressure, before you pour it into conventional wine bottles.

After pouring the wine into the carboy, you will have some leftover vegetable matter, and you could compost them, feed them to chickens or – as I did – combine them with apple peelings and make them into meadowsweet jam.

Some medical authorities caution against women taking meadowsweet when they are pregnant, thinking that its aspirin-like properties could be harmful in large doses – but you should avoid drinking wine then anyway.

Meadowsweet grows across Europe and has been introduced to North America, so look around for it if you live in those places. Perhaps nowhere, though, does it grow so profusely as in Ireland, where these last days of summer are the final chance to pick some.

The Shifting Baseline of our Memories


One of my first memories – I couldn’t have been more than four – was of fishing with my grandfather in a rowboat on a warm summer lake. We were catching bluegill, and I remember his calloused hands delicately removing the hook from their heads, and feeling them squirm in my hands before we threw them back.

Then we were caught in a surprise shower, and I remember watching with alarm as the shores in the distance were replaced by grey curtains of rain. To my child’s eyes we seemed to be adrift and blind, unable to see the way home, and with water collecting around my boots. My grandfather calmly rowed us back to shore; he was a man, and capable.

Most of us who love Nature today can trace it back to some transcendent experience like this; feeling the tingle of distant lightning, or the smell of rain, or the cries of animals in the darkness, or the sight of a breeze rippling an ocean of green barley, or helping a sheep give bloody birth.

Today, however, few children run with magnifying glasses through the woods; in one generation British children went from half its children playing in wild places to one in ten, and in the USA kids with outdoor hobbies fell by half. We also struggle to get kids interested in the sciences, and the usual explanation is that the children don’t have enough “information,” which we think comes through screens. But children today already spend most of their lives in front of screens; they grow up gorging on images and data with no meaning to them, creating a kind of mental obesity that should not be mistaken for education.

As British naturalist and television presenter Chris Packham said, “I’ve lived in a house for eight years, and have walked my dogs in the woods every day, and I’ve never seen a child in those woods, not one in eight years – not one with an air rifle, not one building camps, starting fires, collecting birds’ eggs, climbing trees or all the things kids did when I was younger. If they can’t get stung, slimed and bitten by it, they’ll never love it enough to want to look after it.”

Ironically, we now push for children to become eco-conscious at the same time that we shut them away from any real experience with the natural world. I know many young environmental activists who care deeply about the environment, but know it mostly through screens. Richard Louv, author of Last Child in the Woods, describes ecologists who have never seen the communities they model, which is like a heart surgeon never having seen an actual heart. (Last Child in the Woods, 225)

If few of us know the animals and plants around us, fewer still could say how much they have declined, as we don’t realise how much there used to be. This isn’t simply speculation; Lizzie Jones at the University of London compared the population records of various bird species back several decades, and then asked more than 900 people of all ages to estimate the populations now versus when they were teenagers. Since the younger you are, the fewer years have passed, you’d think the youngest participants would have the best estimates. In fact, the opposite was true – perhaps because older people used to know the natural world better than we do today, or perhaps because they could see more of a change in their longer lifetimes.

Many elders complained that they can no longer hear the sounds of their childhood around them, like the birds whose calls marked the passage of seasons. Recalling the larks that rose from her neighbour’s house, Francie Murray said that “the experience that I describe is a privilege that is denied to the youth of today. The skylark is long since extinct, his demise brought on by modern technology on the farm. The lark built his nest on the open ground in the meadows of the countryside there there is little or no protection from big machinery, fertilisers and sprays which are a feature of present-day farming.”

Daniel Pauly at the University of British Columbia called this “shifting baseline syndrome,” where everyone thinks of the “normal” baseline as whatever they grew up with; he cites photos of fishermen in Florida over decades, who posed equally proudly with ever-shrinking catches.

Homeschooling with the Classics

 

Every night I read the classics of Ancient Greece to my daughter, which you might think will be dull for a child. On the contrary: The Greeks were funny. The other night, we read Plutarch’s biography of Solon, for example — the man most credited for inventing democracy in Athens – and acted out his defiance of the Athenian dictators.

With sticks for swords, we re-enacted the Athenians’ battle for the island of Salamis, and their humiliating defeat by the Megarians. After that, I explained, the lords of Athens created an information blackout, forbidding any Athenian from mentioning Salamis – they didn’t want to be embarrassed anymore.

“What, so everyone pretended like nothing was wrong?” my daughter said indignantly. “When everyone knew otherwise?” Yes, I said – just like today.

“Couldn’t they complain to the rulers if they didn’t like the laws?” she said. No, I told her. They had taken a step toward democracy a generation before, I told her, when a man named Draco created their first set of laws – but they were the original draconian laws, where the penalty for everything was death. That news delighted my daughter, and soon we acted out a new scene of our impromptu play: Mr. Average Athenian litters on the street, meets Draco.

“Hey! That’s against the law!” she said as Draco. Oh, shoot, I said as the Athenian – can I pay a fine?

“No!” she said, as Draco. “The penalty is DEATH.”

That’s ridiculous! I said. “Complaining about it is DEATH,” she said.

Who hired you, buddy? I asked. “Asking who hired me is DEATH.”

As much fun as this was, the gravity of it began to sink in – Solon was ready to die. “What did he do?” my daughter asked.

He sat down and wrote an epic poem about the defeat at Salamis, I explained. He put on his hat, walked to the market, stood on a pedestal in front of everyone, and recited the entire story of the defeat. He might have even sung it, or rapped it.

“What happened to him?”

He persuaded a lot of Athenians that they should take back the island, I explained, and they pressured the rulers, who gave in — and Solon came up with a cunning plan to win this time. It was …

“Yes?” she asked.

I paused, not sure how to proceed. Well, I told her, you remember that part in Bugs Bunny where he dresses up like a woman, and his antagonist drops everything to come over and flirt with Bugs?

“Right?” she asked.

Well, I said, the Athenians did that.

There was a quiet pause. “You’re joking,” she said.

No, really, I said – according to Plutarch, they had their youngest, beardless soldiers dress up as girls and flirt with the Megarians, and then the other Athenians leaped out with swords and yelled, “A-HA!”

After talking about the zaniness of these strategies for a while, I explained that Solon’s reputation continued to spread; he became so famous for his wisdom that when the city was about to erupt in civil war, the people and the leaders turned to him. He was the one person everyone trusted.

What did he do once he came to power? I asked. Did he make himself king?

“No!” said my daughter emphatically, “He said everyone had to vote, create juries, and so on, and made everyone swear an oath to follow the rules of a democracy; no one could change them except him for ten years. Then, after everyone had sworn, Solon said, ‘Good! Now I’m going on vacation – for ten years!’”

Once many students read stories like this, from Roman scholars to Victorian schoolboys to American pioneers; these days I have to introduce them to my daughter through home-schooling. Reading the Ancient Greeks presents no great chore, though, as many of their stories are as melodramatic as any soap opera, and with the occasional screwball turn into pure comedy.

Reading these installments of their true-life melodrama, I wonder why we stopped teaching the classics. These stories link us culturally to the hundreds of generations who read them before, so that when everyone from Roman scholars to Victorian schoolboys to American pioneers quote Pericles or Thucydides, we understand the reference.

These stories take the things we would see in any small town or neighbourhood today — elections, libraries, theatre – and tell us how they began, on rocky outcroppings 26 centuries ago. It cures us of the notion that we are special or superior to our forebears; rather, it helps us know the people on whose shoulders we stand.

Building Homes from Straw

One of the most energy-intensive human activities is building – and for most of us, that means building houses. BBC programmes like “Grand Designs” feature all manner of energy-efficient homes, some of them very creative and high-tech – but one of the most promising building methods comes straight out of the 19th-century American frontier. Despite what you might remember from the Three Little Pigs nursery rhymes, one of the best building materials is ... straw. 

Typically the house has a frame of wooden beams, and then straw bales are used to create the walls, and the straw plastered over to create an adobe effect. Americans in the Old West used this technique to build homes, barns, and even churches, and while the approach was abandoned for decades, builders have realized how sturdy, cheap and ecological most of these homes were.

Straw is plentiful; Ireland alone could probably produce enough straw to meet most of its building needs, without importing any more materials or clearing any more forests. It can form load-bearing walls or can simply insulate. It is lightweight and easy to transport to a building site, unlike steel or stone.

It is easy to work with, and – if you use the old-fashioned, human-sized straw bales -- can be stacked and plastered by amateurs. Unlike most building materials, it contains no toxins that seep out over time. Gathering and baling it does no damage to the environment, and the building waste can be made into mulch. The building material can be cut and shaped with a simple chainsaw or even a regular saw, allowing virtually any shape of house.

It is also one of the most perfect insulating materials around. Insulation is measured in “R-values,” and the higher the R-value, the less heat escapes the home. Most conventional homes are estimated to be R-12 to R-20; most bale homes, R-30 to R-50. The material has a natural trombe effect, allowing it to store heat or coolness and release it to keep your home’s temperature comfortable.

Isn’t straw flammable, you ask? Loose straw is, but bales are tightly compressed, and are no more flammable than wood. The National Research Council of Canada, for example, found that a straw bale wall withstood temperatures of up to 1,850 degrees for two hours.

The big bad wolf cannot blow the house down – the Building Research Center of the University of New South Wales, Australia found in 1998 that bale walls withstood winds up to 134 miles per hour – equivalent to a Category 3 hurricane.

In addition, they are beautiful. Since the walls are thick, they create deep niches for plant-boxes or window seats, and the plastered exteriors look rustic and natural but clean and satisfying.

Straw-bale homes are not perfect; the walls must be kept free of moisture, so most such homes would need decks in rainy Ireland. Pests and rodents might also be tempted to take up residence – although that has been the case in most homes here, straw or not.

I’m told by people who have tried this in Ireland – off-grid, so I won’t name them – that bales should not be used as load-bearing walls, which in retrospect was not a good idea. It’s better to have a strong frame and let the bales form the walls, as bales themselves can warp out of shape or shift over time. It also means that a wall damaged by moisture can be taken out and a new wall installed quite easily.

I visited a couple in rural Wales, two scientists who had worked on climate change for many years and wanted to build a sustainable community. They and three other families bought some land and built gardens, raised animals and, most importantly, built four straw-bale homes quite quickly and easily – all themselves, while never having worked on such a project before and with no professional building experience. The homes cost them a miniscule amount compared to most homes, and as their insulation is so thick, their heating costs are also tiny. Now, several years after their homes were built, they are all in great shape, and they had no expensive mortgages to pay off.

To find out if bale building is for you, consult books like “Serious Straw Bale” by Paul Lacinski and Michel Bergeron, or “More Straw Bale Building” by Chris Magwood.
