Definition
A servitude of Scots law by which lands were bound to a particular mill, obligating the landowner or tenant to bring grain grown on those lands to that specific mill for grinding. In return, the miller received a portion of the grain as toll. The lands subject to this obligation were said to be "astricted" to the mill; the mill to which they were bound was the "thirlage mill." Astriction was the name for the servitude itself — the legal tie that created and sustained this relationship between the land and the mill.
The obligation ran with the land, not the person, making it a real burden enforceable against successive owners and tenants of the astricted acres.
Common Language
Modern common usage (Wiktionary): The act of binding; restriction; obligation. Also used in a medical sense to mean contraction of parts by application of an astringent substance, or constipation.
Historical common usage (Webster's 1913): The act of binding; restriction; obligation. Also a medical term for contraction of animal tissue by astringent application, and constipation. Webster's separately identifies the legal sense — an obligation to have grain ground at a certain mill — as a distinct meaning.
The common English word carries a general sense of binding or constraint, derived from its Latin root. The legal meaning is narrower and more specific: not merely any binding obligation, but a particular species of predial servitude attaching grain-grinding duties to a defined mill. A researcher encountering "astriction" in a general literary or medical text should not assume any property law dimension; conversely, encountering it in a Scots property or agricultural record means something technically precise about land tenure and milling rights.
Recognized Forms
/SUBTYPES
Astriction operated within the broader Scots law institution of thirlage, which encompassed several related obligations:
- Sucken: The body of lands astricted to a particular mill, collectively.
- Multure: The toll in grain paid to the miller as compensation for grinding.
- Sequels: Additional dues (bran, sifted grain) payable beyond the basic multure.
- Knaveship: A customary payment to the miller's servants, sometimes attached to thirlage obligations.
These subtypes are not varieties of astriction itself but are the components and consequences of the thirlage system of which astriction is the foundational servitude.
Why It Matters in Research
Astriction is a term of narrow geographic and temporal relevance — it belongs almost exclusively to Scots property law and is of primarily historical significance, having been largely abolished or rendered obsolete by the Thirlage Act 1799 and subsequent agricultural changes. Researchers working in Scottish estate records, agricultural history, feudal tenure documentation, or pre-nineteenth-century Scots land law will encounter it; researchers in English, American, or other common law traditions almost certainly will not.
Several navigational points matter:
First, the term appears most naturally in historical sources. Post-1800 legal texts treat it as an institution in decline or already extinguished for practical purposes. If you are reading a Scots text from before 1800 that discusses mill rights, grain obligations, or thirlage, astriction is a live legal concept. After 1800, references are increasingly retrospective.
Second, Burrill's entry points to Bell's Dictionary as the authoritative source. George Joseph Bell's writings on Scots law — particularly his Principles of the Law of Scotland and his Dictionary — are the standard authorities for this concept within the historical dictionary tradition. Any deeper research should move from Burrill to Bell directly.
Third, astriction sits at the intersection of several research threads: feudal tenure, predial servitudes, agricultural history, milling history, and the gradual reform of Scots feudal land law culminating in the Abolition of Feudal Tenure etc. (Scotland) Act 2000. A researcher tracing the arc of Scots land reform may encounter astriction as one specimen of the abolished burdens.
Fourth, the term does not appear in English common law sources. Finding it in a legal document presumptively indicates a Scottish jurisdiction or a comparative law discussion.
Historical Dictionary Support
Burrill's entry is spare: it identifies the Latin derivation, places the term in Scots law, defines it as a servitude requiring grain from certain lands to be ground at a certain mill, cites Bell's Dictionary, and cross-references the related entry "Astrict." This is functional but minimal — Burrill was not working primarily in Scots law and did not elaborate.
Webster's 1913 is more expansive than Burrill on the legal sense, adding the detail that "the owner" pays a toll, and also preserving the medical senses (astringency, constipation) that legal dictionaries omit entirely. The Wiktionary entry tracks Webster's closely and adds the explanatory gloss that "the lands were said to be astricted to the mill" — a useful formulation capturing the in rem character of the burden.
Neither Burrill nor Webster's engages with the doctrinal structure of thirlage, the distinction between multure and sequels, or the reform history. For that, Bell's Dictionary and Bell's Principles remain the necessary sources. The historical dictionaries agree on the core definition and uniformly associate the term with Scots law; none offers a competing account of what astriction means.
What the historical dictionaries collectively miss: any discussion of enforcement, the relationship between astriction and feudal superior rights, or the legislative abolition of thirlage. A researcher relying on Burrill alone would have the definition but none of the legal context needed to interpret an actual document.
Jurisdictional Note
Astriction is a term of Scots law with no recognized counterpart in English common law or American law. Researchers working exclusively in English or American legal traditions will not encounter it as a live legal concept. Within Scotland, thirlage and astriction were effectively ended by the Thirlage Act 1799, though their traces remained in title conditions and historical records well into the nineteenth century and beyond.
