Genista tinctoria, dyer’s weed.—Serratula tinctoria, 
saw wort.—Carduus hetrophylus, soft or gentle 
thistle Bidens tripartita, bur marigold; the last

Dyer’s weed. 
This plant they reduce to powder, and add to the

wath their stuffs once or twice, after the dying busi« 
sinefs is finifhed, in a lixivium of wood athes.

boiling heat. 
Bur marigold. 
To give a golden yellow colour, they treat this 
plant exactly like the two last, and soak their yarn 
in the decoction, in the same manner.

Galium mollugo. 
Great bastard madder, native of Scotland. They 
make a strong decoction of the root with water, in 
which they soal: their yarn twice, the first time only 
warm, the second at a boiling heat,
