Ancient grains at the Living Field – 10 years on

The Living Field project has been sharing knowledge of ancient and modern cereal grains for over 10 years [1]. Here we look back at how things evolved from field studies in barley on the Institute’s farms to growing our own range of cereals and finally using bere barley and other flours to make bannocks, bread and biscuits.

The sequence is shown here for bere barley. Seeds are sown, crops are grown. Bere plants support reproductive heads or ears holding grain. Plants are harvested and the grains removed and cleaned. They are ground into meal or flour, then used alone or mixed with other flours to make bread, bannocks and biscuits.

This sequence has sustained people for thousands of years.  Today the grain we eat in Scotland, except for oats, is not grown here – the main cereal products from local fields are alcohol and animal feed. But whatever the future of agricultural produce, the grain-based cycle will remain essential to settled existence. In this retrospective, we describe the Living Field’s shared experience of ‘seed to plate’ over the last 10 years.

School visits to the farm’s barley fields

We began by introducing visitors to the James Hutton Institute’s fields where barley is grown both for experiments and for commercial grain sales. From 2007, the Living Field has been using the farm’s barley to give school parties a first taste of life in the crop.

The larger image above looks down from a barley field at Balruddery farm to the Tay estuary. The school children in the pictures were visiting fields of young barley at Mylnefield farm just above the Tay. This was in May 2007. They walked along the ‘tram lines’ looking at plants and finding ‘minibeasts’ – the first time many of them had been in a crop. They were fascinated with small creatures found crawling on the plants or walking over the soil [2].

The public interest in crops and their ecology in those early visits encouraged us to explore a much wider range of cereal plants than presently grown in commercial agriculture.

Ancient grains at the Living Field Garden

So began a small collection of grain crops which were sown, tended and harvested each year in the Living Field Garden [3]. We began in 2010 by growing bere barley from Orkney, black oat, emmer and spelt wheat, alongside modern varieties of barley, oats and bread wheat. Rye and a landrace of bread wheat from the western isles were added later, then several other barley landraces and old varieties [4].

The collection of photographs above shows a general view of the  garden. including a tall cereal plot (middle right), then c’wise from upper right – a barley landrace from Ireland, rye, black oat, emmer wheat, young spelt ear, spratt archer barley and a bread wheat landrace.

By 2011, the Living Field had combined its practical experience on the farm with the collection of ancient and modern grains in the Garden. Gladys Wright and Jackie Thompson had perfected the way to grow all these different species. We now needed a means to demonstrate processing the grain and making food from it.

Milling and baking

The harvest from the small plots in the garden was too little to make flour enough for open days, road shows and exhibitions. Additional grain and flour (or meal) was begged or bought from a range of sources, notably Barony Mills in Orkney and ‘Quaker Oats’ in Fife.

The Living Field then bought its own rotary quern for grinding the grain into meal and chaff, which is the name given to the other bits we don’t usually eat, mostly the protective sheathing around the grain and the awns.

Now to make a loaf! Fortunately one of the team, Gillian Banks, was already an experienced bread-maker and after some experimentation turned out tasty loaves made from various mixtures including bere and modern barley, oats, emmer, spelt, wheat, rye …. and more [5]!

The whole chain from sowing seed in the ground to making food could now be demonstrated from first-hand experience. We did this at various open events beginning 2012.

The panel above shows (bottom left, clockwise) – visitors experiencing a range of ancient grains and flours, demonstrating the rotary quern, a sheaf of spelt, making things from sourdough, and a four-panel set showing oat grain in a bag, sieving and sorting meal from chaff and finally bread.

Open Farm Sundays

The highlights of our outreach over the years has been LEAF Open Farm Sunday. The Institute is a LEAF innovation Centre [6], so on the first Sunday in June, the farm and science come together to host the event. One of the main attractions is the hub of activity around the Living Field garden, cabins and tunnel. Typically 1000-2000 people visit the hub during the day. We’re mobbed ….. thanks to all!

The essential structure of a successful open day is, firstly, to provide plenty of things to do for young children, to keep them occupied and allow time for older children and grown-ups to talk about what’s on view; and, second, hands-on activity with natural products, things such as living plants, and grain and flour that can be touched, felt and smelled  [6].

Group activities are usually located in the garden’s polytunnel, just in case of rain.  The panel above shows (lower left c’wise) examples of grain and flour, a ‘tasting’, making things with grain and other natural materials, an activity table for children and their grown-ups, and bags of grain from the garden with young scientist sitting on the rotary quern fascinated by oat grains.

Cooking with bere barley – more than bannocks

The thread linking exhibits through the years has been bere barley – Scotland’s barley landrace, an attractive plant, easy to grow.  Bere as a crop declined in the late 1800s and is now restricted to a few fields in the far north. Like most of the world’s landraces, bere faded in competition with modern crop varieties and production methods. Yet it remains a favourite here. Its story continues [7].

Bere and other barleys were traditionally used to make a flatbead or bannock, either on its own or mixed with oatmeal or peasmeal, but  bere meal has many uses when mixed with other flours.

The Living Field has friends and correspondents like Grannie Kate who regularly experiment with different uses of ancient and modern grains. Scones, shortbread, batter, porridge, soups can all include bere as a unique constituent. One of the team regularly adds a a spoon or two of bere meal to their morning’s rolled-oat porridge.

The images above show (top left, c’wise) bere and oat bannocks, a bag of bear meal in Grannie Kate’s kitchen, bere fruit scones and bere shortbread [8].

On the road

Following the Living Field’s appearance at a ‘biodiversity day’ run by the Dundee Science Centre in January 2016, we were invited to join the exhibition trail organised in 2016 by the Centre as part of The Crunch [9]. By this time, we could take take the whole process on the road – seed-plant-grain-flour-food.

Gill Banks and Linda Nell, with Lauren Banks and Geoff Squire, ran the grain to plate events at The Crunch venues. One was in a darkened auditorium at the Dundee Science Centre, another at a local community Centre.

The Science Centre suggested we bring some bread made in the usual way from cereal grain and some made from insects. Gill bought various whole insects and flours and made some insect loaves that several of us had a pre-taste of and concluded they tasted just like nice wholesome loaves.

Anyway, the insects went down a treat at the events and started many a conversation of what we eat and what it costs – insects gram for gram need much less energy and cause much less pollution than most other forms of animal rearing.

The panel above shows scenes from the (top right) the January event) and bottom right (The Crunch) both at the Science Centre, then (top left, down) sheaves of spelt and black oat, globs of gluten extracted from wheat by Gill, mixed-flour bread with dried crickets laid on, and (at the bottom) dried insects for cooking or eating and (centre) barley grain.

Ancient grains in Living Field art

Through working with artists, the team were able to see the plants they had grown become part of artwork. Jean Duncan for example was able to place grain not just as a food but as essential to the development of farming and human society since the last ice. In her work, grains and plants appear close to circles, barrows, landforms and field systems.
Some extracts from Jean’s creations are shown in the panel above. Various ears, spikelets and grains appear commonly alongside mounds and barrows (example right). At top left, ancient cereal plants are stylised as fans, drawn near the centre of  a circular design,  used to create a revolving backdrop for an opera. At bottom left, a section of her ‘teaching wheel’ shows a range of cereal species grown in the region since the neolithic [10].

At Open Days, children like drawing things,  messing with paint and pencil: better then just looking, it helps to give them a lasting memory of what they saw and touched.

Where next

Nearing the end of 2018 and the project will continue its work on bere and other grains, ancient and modern. The Living Field is connecting to the swell of interest in local food and recipes.

Few others can demonstrate the whole chain – not just grain to plate – but from sowing the seed to eating the food and, crucially, saving some grain for the next year’s crop.

The James Hutton Institute has recently been awarded funds for an International Barley Hub. Let’s see what the 2019 season brings!

…… warm bere and crickets?

The idea of ‘insect bread’ always raises interest, even if to some the thought is less than appetising. But insects and bread have a long history together ……

At one time and even now in many places, a bag of flour can have resident insects in the form of weevils. They live and reproduce in it, eat it and recyle it in one form or another (probably best not thought about). They add a little crunchy something to a baked loaf [11].

That’s insect bread ‘by accident’. For several years, and as shown above, Gill and Co have been experimenting with bread made from insect flour mixed with grain flour. The insects tried so far are mainly crickets, raised especially for the purpose (though not by us). Insects as alternatives to fish and meat in European diets is a hot topic now  [12].

Peasemeal Beremeal Oatmeal

Three flours that sustained life on the Atlantic seaboard for centuries. Commonly grown as a crop mixture in the field.  Mixed and cooked into tasty bannocks in the kitchen. Decline to near extinction in the 20th century. Now with a great future as sustainable low-input crops, bringing diversity to the farmed landscape and healthy, nutritious food. 

Peas, bere (barley) and oats have been a staple plant mixture giving protein and carbohydrate through the centuries of farming on the Atlantic seaboard. Yet in Scotland, as in much of Atlantic Europe, their role diminished within living memory.

Peas  declined in area from the mid 1800s to to almost nothing in the 1930s. Bere dropped out of census records in the 1880s but was then nearly lost except in a few northern fields. Oat fell from being the dominant grain crop over the last few hundred years to covering less area than barley and wheat by 1950 [1]. Their decline is now being reversed.

Peas as crops and food

Traditionally peas along with bere and oats, and sometimes beans, was the staple protein food of the rural working population in Scotland. They were the local pulse and grain – the sustaining combination of plants that once fed the world and still feeds large parts of it.

Fenton’s Food of the Scots [2] cites many records from the 1400s to the late 1800s of peas, beans and cereal grains grown alone or in mixtures. Similarly, the flours of peas, oats and bere were eaten as bread and bannocks, either as sole constituents or baked in combination.

The pulse crops were certainly recognised and widely appreciated here for hundreds of years. A 1426 Act of Parliament in Scotland stipulated that a farmer should sow 1/12 of his labour in peas [2],  not just for protein food but to fertilise the soil with nitrogen (though the process of biological nitrogen fixation by legumes was not understood until many centuries later).

The products of peas and beans were grown locally, traded across the country or imported by sea, often from nearby Atlantic and Baltic ports. Though peasemeal was demeaned as a food of the labouring classes in some regions, the inclusion of peas in the subsistence diet was recommended by Hutchison in 1869 [2] as contributing to a healthier and longer life for the rural worker and their family.

Decline of peas

The records cited by Fenton indicate peas as a crop and food were more important here than beans Vicia faba. Yet by the mid-1800s, that order was reversed. At the first crop census in 1854, beans occupied 6 times more area than peas [1]. The cause of the decline of peas as a crop is suggested by MacDonald (1908) as due to ‘the extended use of potato’ in the subsistence economy [2] and by Porter  (1925) to the replacement of pulses by clover and grass mixtures [3] that are better at maintaining soil fertility.

Well into the period up to the 1950s, both pulses were named individually in the census and classed as grain crops to be harvested like cereals, yet unlike the cereal grains, they continued to decline in area despite a short-lived revival in the late 1940s (when food imports and nitrogen fertiliser were  restricted).

Peas became a minor crop by the 1930s and disappeared from the annual census in the 1950s. Beans went a decade or so later. They covered too small an area to be recorded in the annual summary. They reappeared gradually from the 1960s in different forms, such as ‘vining peas’ for human consumption, but that’s another story, and despite a rise in sown area similar to that of the 1880s, peas and beans together now cover 1-2% of the cropped surface, a very low percentage.

The benefits of all three products – peasemeal, beremeal and oatmeal – to health and environment are increasingly recognised today. Here, we wonder what peasemeal-beremeal-oatmeal bannocks tasted like and decided to find out.

Grain – top bere, middle peas, lower oats – is ground to beremeal, peasemeal and oatmeal, which are mixed with water, pressed on dry meal into a round, 1 cm thick, and heated in a pan until the bannock is cooked golden brown.

Peasemeal-beremeal-oatmeal bannocks

For much of recorded history in these islands, wheat was not as widely grown as oats and barley, and when it was grown or imported, it was more to feed the wealthy. Beremeal and oatmeal do not ‘rise’ much by themselves, so were most commonly eaten as bannocks, a form of flatbread [2]. The flours were mixed with water, patted into a round, typically 1 to 2 cm thick, and baked on a hot surface on or by a fire.

To try out the method, flours were sourced from water-powered mills at Golspie in Sutherland and Birsay on Orkney [4]. Then trial and error – peasemeal and oatmeal, peasemeal and beremeal and all three together, the latter preferred for the blend of tastes.

The oatmeal was medium-ground and gave some granularity to the mix. The peasemeal had a yellowish colour, while the beremeal was more of a light brown than a standard refined wheat flour.  On the packets, peasemeal had a protein content of 20.4% and oatmeal (as most unrefined cereals) around 13%.

The three were placed in a bowl at about 1:1:1,  or slightly more oatmeal than each of the other two, mixed into a thick paste or dough with water, turned out onto the board with a little beremeal on it to stop it sticking and then pressed into a bannock (about 10 -15 cm wide and 1 cm thick).

It took 10 to 15 minutes to cook the bannock slowly in a cast iron pan, very lightly oiled with cold-pressed rapeseed, though oiling is not essential. Heat sources tried were a modern gas stove, an indoor wood stove and an outdoor fire.

The three-meal bannock was tasty and filling, eaten with butter or marge (could try a drizzle of oil), marmite, various cheeses and dipped in soup. A satisfying experience.

Yield and environmental benefit

Pea Pisum sativum is now grown in various forms, for animal feed, for canning and freezing to feed people and as a fresh vegetable. The peas traditionally used for peasemeal or flour tended to be marrowfat or similar types, harvested when mature [but see note 4]. Peas need no nitrogen fertiliser and less pesticide than most non-legume crops.

Bere, the traditional landrace of barley Hordeum vulgare, is now grown only in a few localities, but appears to need less fertiliser and pesticide than modern two row barleys.  Oats Avena sativa were overtaken by barley in the middle to the 1900s as the Scottish cereal crop of choice, but they too need less pesticide and fertiliser than barley and recently oat yields have increased to rival those of spring barley. Oat is also nutritionally superior to barleys and wheats.

Many records over recent centuries describe the growing of two or three crops mixed together in one field. ‘Mixed grains’ was recorded in the crop census for most of the 1900s, while mashlum  – a mix of peas or beans with oat or barley – was common enough to be cited as a distinct crop category from 1944 to 1978 [5]. As related elsewhere on the Living Field web site (see Mashlum – a traditional mix of oats and beans) these crop mixtures disappeared from the census records but are still grown by a few farmers who value their contribution to fertility and nutrition.

The yields, nutritional content and environmental benefit of traditional landraces and mixed grains are being researched and quantified at the James Hutton Institute, Dundee [6, 7}.

Teaching about grains, milling, flour and food at Open Days

The Living Field bought its own hand-powered corn mill a few years ago. It consist of a stone base and two grinding stones. The latter were honed by Mr Roberts from the Hutton’s workshop and the whole was supported by old tyres. Grain (in this case oats, centre top) is fed into a vertical channel in the upper stone and falls  down through to the gap between the stones.

The stones are turned by the wooden rod, as shown by Mr Young and two visitors at an Open Day (this one in 2012). The grain is ground between the stones to a mix of meal and bran (the husks of the grain) which gets pushed out and collects in the stone base from where it is brushed off into a container (lower right). The meal and bran are separated by hand using a sieve (lower left).

At Living Field open days – at Open Farm Sunday for instance – visitors can see the whole process from growing the plants from seed, harvesting grain, grinding the grain and separating the meal from the chaff. Gill Banks shows how to make bread from the flour made from these ancient varieties.

The Mill at Atholl

The historic watermill at Blair Atholl. Absence of corn growing in the surrounding area today. Extensive field systems and enclosed land in the mid 1700s. Andrew Wights 1780s descriptions of innovation, enterprise and crop diversification. Part of a Living Field series on old corn mills.

The watermill at Atholl [1] offers a welcoming break to journeys along the A9 road, offering – in addition to the working mill – coffee and freshly baked bread from a variety of grains. In 2017, the mill and its bakers gained some deserved exposure on a BBC2 television programme, Nadiya’s British Food Adventure, presented by Nadiya Hussain [1].

The remaining corn mills in the north of Britain tell much about the phasing in and out of local corn production over the last few centuries. The Living Field’s interest in this case lies in the mill’s history and location, being a substantial building but presently in an area that has no local corn production. In this, it differs from Barony Mills in Orkney which lies within an area of barley cultivation that still supplies the mill [2].

The images above show the water wheel fed by a lode that runs from the river Tilt to the north, the main grinding wheel (covered, top l), hoppers feeding the wheel and an old mill wheel. The watermill’s web site [1] and the explanation boards in the mill itself describe the history of the building and workings of the machinery.

The Atholl watermill was a substantial investment, but what strikes today is the absence of corn-growing (arable) land in the area. When visited in 2017, very few fields were cultivated.

What do the historical maps tell us?

The information inside the mill states that it was present at the time of Timothy Pont’s map of the 1590s [3]. It is there on his map, just south of ‘Blair Castel’. But Roy’s Military Survey [4] of the mid-1700s gives the best indication of the possible extent of cropped land in the area. Features on the Roy map (copied below) include ‘Blair Kirk’ (church) which still stands at what is now known as Old Blair and ‘Tilt Bridge’ on the road that ran north of the Garry; then areas of enclosed land or parkland, bounded by tree lines; and the Mill, shown within the white circle in the upper map, with its lode clearly leaving the River Tilt to the north and flowing past the mill to enter the River Garry upstream of where the Tilt joins it.

The Roy Map shows what appear be clusters of field systems on both sides of the Garry, depicted by short parallel lines suggesting rigs, some indicated by white arrows on the upper map. The lower map has been displaced to show more field systems around Aldclune.

Later, on the first edition of the Ordnance Survey 1843-1882, the village of ‘Blair Athole’ has started to take shape, the corn mill is marked being fed by a Mill Lead originating at a sluice off the River Tilt. Later still, the Land Utilisation Survey 1931-1935 shows arable land remaining, consistent with the location of many of the field systems on Roy’s map.

Therefore crops, and they must have included corn, whether oat or barley, were grown in the region and presumably fed the mill, but more information on what was grown was reported by Andrew Wight, travelling 30 years or so after Roy.

Andrew Wight’s survey of 1784

Mr Wight’s surveys of agriculture in Scotland in the 1770s and 1780s again provide rare and sometimes surprising insights. He meets and reports on mainly the improvers, the landowners and their major tenants, less so the householder and small grower. Yet he was there at a crucial time in the development of food production and able to present a unique and consistent account throughout mainland Scotland.

Part way through his fourth survey [6], he spent the night in Dalwhinnie, then on travelling south towards lowland Perthshire, he stopped at Dalnacardoch, commenting that the innkeeper was a ‘spirited and enterprising’ farmer. There he reports a “clover field, dressed to perfection; an extraordinary sight in this barren country” and also “turnips in drills in perfect good order, pease broadcast, bear and oats with grass-seeds”, and notes ‘great crops of potato are raised here’. [Ed: bere is a landrace of barley.]

On ‘Athol House’ (near the mill) he concentrates on the animals, various breeds and hybrids of cattle, and also sheep; but on the tilled land, he writes the “Duke’s farm is about 700 acres arable; of which not more than 120 are in tillage, the rest being hay or pasture.” The rotation is “turnip broadcast, barley, oats and turnip again”. So corn crops – barley and oats – occupied 2/3 of the 120 acres, equivalent to 80 acres or 32 hectares (abbreviated to ha, 1 acre = 0.405 ha). It is uncertain what this land yielded at that time, but assuming it was 1 t/ha or one-fifth of todays typical spring cereal harvest, then that’s 30 tonnes of corn annually. By itself it does not seem enough for such a big mill.

Again, it is unclear whether tenants and crofters are included in the stated area, but they were probably not. For example, later he mentions tenants, including the innkeeper and farmer at ‘Blair of Athol’ who grew corn for his own local consumption. The extent of other corn land cultivated by small tenants, for example, on the field systems shown in the maps above, is not mentioned.

Mr Wight continues in his appreciation of the standards as he moves south, finding after Killicrankie and towards Faskally, an enchantment of orderly farmland. On the road south to Dunkeld, he writes ‘hills on every side, some covered with flocks, some with trees and small plantations, mixed with spots of corn scattered here and there; and beautiful haughs variegated with flax, corn and grass.’

Driving along the A9 road today, the land flanking the Garry seems impoverished and the climate inhospitable for crops, but Wight presents an entirely different view: innovation, improvement, and diversity of plant and animal husbandry. As in many upland areas, the land reverted to poor pasture, in some instances as recently as the 1980s. Why? Higher costs of growing crops, low profit margins, easier alternatives based on better transport connections and ready imports of cereal carbs.

Feeding the Romans

Thoughts on a visit to the exhibition Roman Empire – Power and People McManus Dundee, on 14 March 2015.

This fine, informative display gave evidence of the Roman presence north of the Antonine Wall (between Forth and Clyde) around 2000 years ago. They set up marching camps and lines of communication, patrolled a long and complicated frontier, built great fortresses, then retreated. Yet few things remain to tell of their everyday life.

One was scale armour, known as lorica squamata [1], fragments found at the site of the fort at Carpow, near the junction of the rivers Tay and Earn in Perthshire. These small samples, linen cloth as backing, sown with 1-2 cm wide sheet-bronze scales, are stated to be the best preserved of this type of army gear in north-west Roman europe. They are rare intact because the linen cloth usually rots and disappears. Someone might have worn this armour to help protect them from a thrown stone or spear or a body blow from wood or metal. It is not known whether the fibre plant flax Linum usitatissimum used to make the linen was grown locally or even whether the cloth was made here [2]. There was a trade in linen throughout the empire.

Another was an amphora (a clay pot), reconstructed from pieces found at Carlungie, Angus, lying in one of the dwellings adjoining an earth-house or souterrain, used as an underground storage chamber. Amphora such as this were used to move wine, oil and other essentials round the empire. A note by the exhibit told the amphora was from Gaul (France) and contained French wine. Who brought it here is not known, but you can imagine the party.

Forts and fortresses along the northern frontier

These exhibits were some of the few fragments remaining in this area from the massive resourcing of the empire’s northern frontier. The Romans made Britain a province in 43 AD and by the 70s AD had established fortified lines and supply routes through (what are now) Perthshire, Angus, Aberdeenshire and Moray. They patrolled well north of the Antonine Wall, which itself is more than an hour’s car-drive north of Hadrian’s Wall in northern England.

They built and manned forts close to transport routes by land and water from the south and east, as at Carpow, and camps and signal towers along the Gask line that ran north of Stirling and continued north east along fertile Strathmore as far as the east coast near Stracathro, and from there, dog-legging north and north west across Aberdeenshire to Moray. A long way to march. A long way from home.

Surprising is the size of some of the garrisons. The one at Carpow, close to the Tay estuary and not far from the North Sea, and thought to be occupied between 180 and 220, was designed to hold 2000-3000 people. The massive base at Inchtuthil – a legionary fortress – by the Tay river west of Meigle (image above), commanded the way north from Perth and was estimated from its dimensions and excavated buildings to house 20,000 to 50,000. A small town! To do its job today, it would need to be sited a few miles farther west to command the A9 and railway from Perth to Inverness.

Roman Inchtuthil existed only for a few years in the AD 80s before it was purposely abandoned. Even if not fully occupied, these garrisons must have held thousands to tens of thousands of people, many of whom were soldiers with big appetites.

How to feed thousands of soldiers

They all had to be fed. They would have brought and tended some of their own livestock and perhaps grown some crops and vegetables nearby, but the staple food would have been grain – wheat, barley or oat. (There was no maize, potato or turnips then.) Just think how many packets of porridge oats would be needed to feed all those men every morning [3], and that grain would have had to be transported over long distances from the south or else stolen or coerced as tribute, or tax, from local people.

The SCRAN entry states: “The Roman army was adept at self-sufficiency. At Inchtuthil the legionaries exploited local resources of wood, stone, gravel, and clay to build their fortress. They manufactured their own lime, bricks, and pottery on the spot. Food and other raw materials such as leather would have been obtained from the natives, probably in the form of tax. The massive granaries at Inchtuthil hint at the scale of such levies.” And these granaries, or grain stores, were big, as shown by the diagrams and aerial images made during archaeological digs (online references below).

The exhibition says that when the Romans came the area was populated by farming communities of native tribes, scattered and based around fortified hill tops. This was the late Iron Age, so agriculture would have been widespread, but even so it would have been very hard pressed to support tens of thousands of soldiers in addition to the existing people. Imagine working hard all year to grow crops and then when they were harvested, you had to give away a lot of the grain for the privilege of having the Romans living nearby. The invaders can’t have been popular and presumably that is why they had to build these lines of communication and massive fortresses.

In conclusion

The Romans did not stay long. They arrived (in what is now Scotland) in the 70s (AD), which is about one thousand nine hundred and fifty years ago, but they were gone in less than 150 years. Their leaving is said to be the result of things happening elsewhere in the empire. Rome was too stretched – but (you have to ask) – was it the midge!

The iron age skills of growing crops and tending stock continued to the present time. So did working hard all year and giving away the harvest to those wealthier or more powerful. The Romans had no monopoly on oppression. It became endemic to northern agriculture.

The bere line – rhymes with hairline

Rhymes with hair line …..

In Landrace 1 – bere the query arose as to whether there was a bere line from the neolithic (late stone age), a line of transmission of bere (barley) seed from the first settlers in these regions to the present day. Another question was when bere and barley became  distinct – they are the same plant species, but just look a bit different, close up.

So since bere is our most famous and still-grown-in the-wild-but-only-just cereal landrace, the Living Field will explore the bere line as a fairly random walk through time, backwards and forwards that is,   putting facts and photos on this web site as we find them.

At some point in the future, we might order them into a chronological list, starting with the earliest and ending with the most recent, but ‘random’ suits us for now.

Here’s an image of bere in the Living Field garden, a cereal beauty!

Thorburn’s diagrams

The bere line – rhymes with hairline

Thomas Thorburn used diagrams to get a point across: for example, diagrams  in the form of  squares to represent large numbers of things. If the reader was no good with figures, then they might get a better idea by comparing two squares of different size to see which was larger and which smaller, and by how much.

His “Diagrams, Agricultural Statistics of Scotland for 1854” was based on agricultural census data collated by the Highland Society and gives areas grown with various crops and output in total bushels of grain and in bushels of grain per acre, including those for barley and bere.

Title page of ‘Diagrams’ by Thomas Thorburn, set by the Living Field on a greyscale image of an Orkney bere field (Living Field)

Bere (or bigg) and barley are clearly distinguished in the pages of Diagrams as different crops.

Summary

The agricultural census in Diagrams tells us much about bere and barley in the 1850s.

  • Bere was grown mostly in the north and west, but occurred in most agricultural census regions. Farmers throughout Scotland would have been familiar with it.
  • The area in Scotland sown with bere was just less than 10% or one-tenth that sown with barley.
  • Yields of barley and bere, when expressed in modern units were both 1.5-2.0 tonnes per hectare (t/ha), compared to present national average yields of 5-6 t/ha for spring barley.
  • In Scotland as a whole, bere yields were a bit less than those of  barley (about 80% or 90% depending on how yield was calculated), but where they were both grown in the same area, as in some northern and north-eastern regions, their yields were similar.
  • Bere has now almost disappeared as a commercial crop, whereas barley is the most widely grown corn in Scotland, going mainly to malting and animal feed.

Where was bere grown in the 1850s?

The area grown with bere in 1854 was about 9% of the area of barley. So in the whole of Scotland, just over ten times more barley was grown than bere. And while most bere was grown in the north and north-east, in places such as Aberdeen, Orkney and Shetland and Caithness, it was grown in a small area in many other places, including areas such as Haddington which are considered to be high-yielding. (The names Aberdeen, Orkney and Shetland, Haddington, refer to census areas.)

Here are some figures. The area grown with bere in census regions was, at the top end, Aberdeen 5322 ac, Orkney and Shetland 2922 ac, Caithness 2710 ac, Argyll 1888 ac; and at the bottom end, Perth 502 ac, Haddington 40 ac and Roxburgh 6 ac. The abbreviation ‘ac’ refers to acre, which is about 40% of the hectare, the present metric unit (1 acre = 0.4047 hectare; a hectare can be visualised as a square of 100 m by 100 m).

For barley, the figures at the top end were Fife 27,938 ac, Forfar 25,222 ac, Perth 23, 710 ac, Berwick 16,576 ac; while figures in the north and west were Orkney and Shetland 149 ac, Caithness 265 ac and Bute 389 ac.

What did it yield

Thorburn gives yield in bushels per acre, bushels being a measure of dry volume, used for grain, and acre being a unit of area widely used until recently, and still used locally. He gives the total bushels produced in each census region (from which bushels per acre can be calculated by dividing bushels by the area of the region) and in a separate diagram, he gives bushels per acre for each region. The two estimates are not always the same, so here we use Thorburn’s bushels per acre figures rather than our calculated figures.

Using standard conversion factors and our estimate of 1 bushel of bere = 21.8 kilograms (see Light on bushel), the national average yield of bere was 1.77 t/ha (tonnes per hectare) and of barley 1.93 t/h, so the yield of bere was just more than 90% (nine tenths) of the yield of barley.

The yields vary between regions, but where both barley and bere are grown together, especially in the north and west, the yields are not that different. In Caithness, for example, barley is 36.0 bushels per acre and bere 36.5 bushels per acre.

Caution

In Diagrams as it appears online, there is no description of the methods by which the census was conducted. It is presumed the Highland and Agricultural Society of Scotland did the work and handed the information to Thorburn who constructed his diagrams.

The yields of crops would have been difficult to measure consistently in the field or on the farm. Harvested grain differs in water-content depending on the weather, the locality and the variety of the crop. And grain also will differ in how ‘clean’ it is , how free of the bits and pieces of plant material that may be harvested with it. Today, yields reported in the annual census are given to a stated water content; so if the actual content measured in the combine harvester or in the grain store differs from this stated content, then the mass has to be corrected to allow comparison of near-dry mass between fields, farms and regions. No indication is given in Thorburn of how the dryness and cleanliness of the grain were standardised across regions.

The way the bushel was measured also probably varied. Perhaps some farms used a standard bushel measure (e.g. a barrel or basket) whereas others might have used a container, such as a cart, that they knew held a given number of bushels.

And then the areas sown with the crops were stated very precisely, sometime to several hundred thousand acres and three quarters. But were all fields measured so precisely? What if crops were grown in strips or parts of fields – was the area grown with each strip or part measured? It is difficult today to measure accurately the area of all fields in Scotland sown with a particular crop – and that is with all the official demands to record what was grown where and when.

Despite these uncertainties, the census was a major achievement. It must have taxed the Highland Society’s officials and local organisers. And they probably did have a very good appreciation of areas and outputs. But in some regions they appear to have come up against difficulties that were too great – for example, the yield of bere in Orkney and Shetland is omitted from Thorburn, despite much bere being grown there.

Light on bushel

When trying to work out how much grain was produced by crops such as bere, barley and oat in the 1800s, it was necessary to convert the bushel, the unit of measure that was common at that time, to the kilogram, which is the unit of weight in the modern International System (abbreviated to SI).

The bushel is a unit of ‘dry volume’ for measuring things like grain and meal rather than liquids. Farmers and grain traders  used a standard basket or barrel which when full would hold 1 bushel, equivalent to 8 gallons.  But obviously a bushel of ball bearings weighs more than a bushel of bere grain. So before it can be converted to modern units, the bushel has to be calibrated for each type of filling.

Table, jug and balance

Things used: table, kitchen measuring jug to 0.5 or 1 litre, kitchen balance (e.g. used for weighing out flour), lightweight container and  a bag of bere grain, grown in the Living Field garden, harvested and air-dried for some months. The bere grain was cleared of stems and leaves – any long awns still attached to individual grains were broken off.  The jug was filled with grain slowly. When a quarter full, the jug was banged gently on the table twice to consolidate the grain. The same was done when half full, three-quarters full and almost full. When full, the container was placed on the balance and the scale brought to zero. The grain was poured into the container and the weight noted.

In this instance, 0.5 litre of bere grain weighed 300 g (not 299 or 301).

Conversion

A bushel equals 8 gallons or 36.37 litres. So a bushel holds 72.7 of the 0.5 litre measuring jug. Since 0.5 litre of bere grain weighed 300 g, a bushel of bere should weigh 21.8 kg.

The bushel is used in some countries, including the USA and Canada, as a unit of weight and so a bushel has a different weight assigned to it for each type of grain. We are pleased to see that the USA’s standard bushel of barley is 21.77 kg, close to our estimate. Their bushel of wheat and several other small grain crops and beans is  27.2 kg while that of oat is 14.5 kg. It means wheat is heavier and oat is lighter than barley or bere for a given volume. So a person would be happier carrying two bushes of oat than two of bere.

What causes the difference in the weight of a bushel? Provided the cereals are dried to a constant moisture content, the difference lies in the proportion of the (heavier) grain to the surrounding protective husks. Wheat grain commonly falls out of the husks at harvest so the light material may not be included; oat is more husky.

Therefore when converting yields of bere in bushels, we will used the conversion, 1 bushel = 21.8 kg.

Note of statistical procedures: the methods reported above can be used in a fun-sized comparison of different cereals and beans. A proper  scientific calibration would check the balance with standard weights at the beginning, then repeat the procedure several times with different lots of grain from the same harvest to get an average with a estimate of the variation. If two corn crops were compared, the average plus variation would allow a statistical test of whether the two were really different.
