Definition
An obsolete English tax levied on each hearth or fireplace in a household. Fumage — also rendered as fumagium in Latin sources — is the same imposition known variously as fuage, hearth money, and smoke farthings. The tax was assessed per chimney or hearth as a proxy for household wealth, on the theory that the number of fireplaces indicated a family's means. It belongs to a broader family of ancient English fiscal charges tied to the physical features of a dwelling rather than income or land value.
Common Language
Modern common usage (Wiktionary): A hearth tax; also, separately, a surrealist art technique devised by Wolfgang Paalen in which candle or lamp smoke is used to make impressions on paper or canvas.
Historical common usage (Webster's 1913): Hearth money. "Fumage, or fuage, vulgarly called smoke farthings." — Blackstone.
Editorial note: The common and legal meanings are closely aligned for the historical sense — both refer to a hearth tax. The significant trap for modern researchers is the Wiktionary entry, which leads with the legal/historical meaning but immediately introduces the Paalen art technique. These two senses share no legal relationship. A researcher encountering "fumage" in an art history or surrealism context should not assume any connection to tax law or feudal obligation.
Common Confusion
Fumage, fuage, and hearth money are used interchangeably in historical sources, but researchers should treat them as variants of a single tax concept rather than distinct impositions. Fuage is sometimes distinguished by derivation — from focus (hearth) rather than fumus (smoke) — but the underlying charge was the same. Smoke farthings was the vernacular term. Conflating any of these with chiminage (a toll for passage through a forest) or scutage (a feudal payment in lieu of military service) is an error; those are separate obligations with distinct legal histories.
Why It Matters in Research
Fumage is a term researchers will encounter almost exclusively in historical English legal materials — treatises, year books, and early common law commentary — rather than in modern statutory or case law. Several navigational points matter:
First, the entry point is Blackstone. All three source dictionaries trace the term to 1 Bl. Comm. 324, making that passage the authoritative historical anchor. Researchers working on fumage should consult Blackstone directly rather than relying on dictionary paraphrase.
Second, variant spellings are numerous and inconsistent across the corpus. Fumagium, fuage, fumage, and smoke farthings appear interchangeably depending on whether the source is in Law Latin, Norman French, or English. Keyword searches on any single spelling will miss material indexed under the others. Cross-searching all variants is essential.
Third, fumage sits within a cluster of obsolete household and hearth-based taxes that were politically contentious in seventeenth-century England. The Hearth Tax of 1662 and its eventual repeal in 1689 are the legislative landmarks most likely to appear in corpus materials adjacent to fumage references. Researchers exploring the constitutional or political dimensions of taxation history will find fumage cited as a historical precedent in that debate.
Fourth, because fumage has no surviving modern legal application, its appearance in a document is almost always a marker of historical exposition or antiquarian legal writing. It should prompt a researcher to consider what broader argument about fiscal history or feudal obligation the author is building.
Historical Dictionary Support
The three source dictionaries are in full agreement: fumage equals fuage equals smoke farthings, with Blackstone as the common authority. Burrill's is the most informative of the three, supplying the Latin root (fumagium, from fumus, smoke) and confirming the equivalence explicitly. Black's first and second editions add nothing substantive beyond the cross-reference to fuage and the Blackstone citation.
What the historical dictionaries omit is notable. None contextualizes fumage within the broader seventeenth-century hearth tax controversy, none distinguishes fumage from the statutory Hearth Tax of 1662 (which was a distinct and more fully documented imposition), and none flags the variant spellings a researcher would need for corpus searching. Webster's 1913, outside the legal dictionaries, is actually the most candid — its brief entry quotes Blackstone directly and signals the vernacular term "smoke farthings," which is useful for understanding how the term appeared in non-legal historical writing.
