Run rig

Run rig is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Run rig rather than just read about it. In short: Run rig, or runrig, also known as rig-a-rendal, was a system of land tenure practised in Scotland, particularly in the Highlands and Islands. It was used on open fields for arable farming.

Key takeaways

  • Run rig belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Run rig to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Run rig from memory before moving on to harder problems.

Reference excerpt

Run rig, or runrig, also known as rig-a-rendal, was a system of land tenure practised in Scotland, particularly in the Highlands and Islands. It was used on open fields for arable farming. Scottish Gaelic names include mòr-earrann (lit. 'large portion'), magh mu seach ('one field at a time'), iomair mu seach ('one ridge at a time'), fearann-tuatha ('peasant field'); in Scots it was generally rin-rig. Its origins are not clear, but it is possible that the practice was adopted in the late medieval period, supplanting earlier enclosed fields which were associated with a more dispersed pattern of settlement. It fell into decline mainly over the last quarter of the 18th century and the first quarter of the 19th century. The land was divided into towns or townships, comprising an area of cultivable "in-bye" land and a larger area of pasture and rough grazing. The in-bye was divided into strips – "rigs" – which were periodically reassigned among the tenants of the township so that no individual had continuous use of the best land. This periodical reassignment can be considered a defining feature of run rig. The majority of townships were rented by tacksmen and sublet to the actual farming tenants. Some tacksmen would have leases on several townships. The detailed working of run rig differed from place to place. The degree of co-operation in these communal farms was one of these aspects. In some instances, where ploughing was carried out by horse gangs, the responsibility for this was shared among the tenants – so providing an obvious communal activity. The Breadalbane estate was an example of this. However, there is no evidence for this sort of organisation on Tiree, where the arable lands were almost entirely ploughed. A further complication was that many parts of the West Highlands used the caschrom to work arable, especially in the Hebrides, so there was no need for a shared plough team. Two documented methods of working run rig demonstrate the relatively limited level of co-operative working. The first is found in a 1785 survey of Netherlorne on the Breadalbane estate. Here the typical township had eight tenants who would plough all the arable land, then divide it into parts judged to be of equal quality and draw lots, for each crop, as to who would occupy each part. The tenant of each part would then prepare his own section for sowing, broadcast his seed and then finally harvest. The second example is on North Uist, where spade and caschrom working was used. Here the land was divided before any working of the soil – each lot was worked entirely individually by the occupier. Dodgshon discusses the misconception that communal working was the main characteristic of run rig. Instead a key defining feature was the holding of intermixed strips of land on the arable area. His conclusion is that run rig was not an archaic system of management based on communal ownership; rather it was a system that valued private property and employed communal activity only when necessary. From the mid-18th century the system was steadily supplanted in Scotland as the in-bye was divided into crofts under fixed tenancy, but run rig survived into the 20th century in some parts of the Hebrides. Where Crofting began to dominate in the Highlands and Isles, the Lowlands transitioned to estate arrangements of individual farms whose lands were laid out in the typical rectilinear field enclosure systems, with one or many fields farmed by the one resident family. In Ireland, a similar system was called rundale. The run rig system of tenure should not be confused with the agricultural practice known as rig and furrow, which produced permanent ridges in arable fields. This resulted from the horsedrawn plough being worked in a clockwise direction, with the mould board turning the furrow to the right, thereby creating these ridges ("rigs") in the fields over time. A run rig system of agriculture may or may not produce a rig and furrow landscape, depending on the method of cultivation used.

Worked examples

Example 1 — a first encounter with Run rig

Start with the simplest possible case. Write down what Run rig claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Run rig before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Run rig ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Run rig

In research
Run rig appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Run rig in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Run rig is common in secondary-school and first-year university syllabi. It links to neighbouring topics History of agriculture in Scotland, Land tenure, Real property law of Scotland, so understanding it makes those chapters shorter.
In everyday life
Look for Run rig outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
