_The Fullers Teasel is distinguished from other plants of the same tribe by having its leaves connected at the base, the flower scales hooked, and the general calyx reflected or bent back._ The seeds of this plant are usually sown in strong rich land, about the commencement of spring. The flowers appear in July, and the blossoms begin to decay in the following month. Shortly after this the heads are cut off, and exposed daily to the sun until they are perfectly dried. In the clothing counties of England the fuller's teasel is an article of considerable importance. The crooked scales accompanying the flowers are so hard and rough that the heads are employed for raising the nap of woollen cloths. For this purpose they are either set into flat boards like cards, or are fixed round the circumference of a large and broad wheel. The former are used with the hand; and the latter is turned round whilst the cloth is held against it. 54. _MADDER_ (Rubia tinctorum) _is a rough, trailing plant, that grows wild in several parts of the South of Europe, and is much cultivated in England and Holland on account of its roots, which are used by dyers and calico-printers._ The land best adapted for the cultivation of madder is a soft, sandy loam. When the roots have attained sufficient growth, they are taken up, carefully peeled, and dried in an airy shed. After this they are conveyed to a kiln, where they undergo a kind of management somewhat similar to that adopted in the drying of hops (260). The next process is to pulverize them, which is done by pounding or grinding; a secret that was long exclusively possessed by the Dutch. Madder is extensively used in dyeing, not only on account of its yielding a fine red colour, but also as forming a first tint for several other shades. The madder used for dyeing cottons in the East Indies, is, in some respects, different from that cultivated in Europe. And, in the neighbourhood of Smyrna, and in the island of Cyprus, a kind of madder is grown which affords a peculiarly bright and beautiful colour. This root is sometimes employed in medicine, in obstructions of the bowels, rickets, and a few other complaints. It tinges water a dull red colour, and spirit of wine a deep bright red. When eaten by animals, it stains even their most solid bones. Cows are remarkably fond of the madder plant; and when they freely eat of it their milk becomes red, yet the cream which it affords makes a yellow butter, 55. _SANDAL WOOD, or YELLOW SAUNDERS, is a yellowish, odoriferous wood, which is imported from the East Indies in logs or short pieces, chiefly as a perfume, or for the manufacture of ornamental articles._
