Note 89 — ARCHIL.
William Johnston translation
This plant grows in the neighbourhood of Montpelier, and above all, in the flats of Languedoc. In harvest, the time when it is collected, the peasants assemble from the distance of fifteen or twenty leagues around, and each gathers on his own account. It is bruised in a mill, and the juice must be immediately used; some mix with it a thirtieth part of urine. It is poured over pieces of canvas, which they take care to provide, and which they rub between their hands. These rags are dried in the sun, and then exposed, above a stone stove, to the vapour of urine mixed with quick-lime or alum. After they have imbibed the juice of the plant, the same operations are repeated till the pieces of cloth appear of a deep blue colour. They are called in commerce tournesol en drapeaux. Large quantities of them are bought up by the Dutch, who make use of them to colour wines and the rinds of their cheese.—Trans.
