In order to dye worsted and yellow, ihcy undergo tlie usual preparation with tartar and alum : of the latter 4 ounces are. y p<»und of wool, or 1(X); of I he I mci", one ounce is sutHcient for yellow ; after dissolving both, the ikodl is boiled in the same manner as in the preceding colour. A fresh liquor is next to be made for the welding (■ u ^, in die pro- portion of 5 or61bs. of dyeiV-weed ■ry pound of stud". Some in- close the drug in a clean woollen bag, to prevent it from mixing with the cloth to be dyed ; and, in order to keep the bag down in the copper, Uiey lay a cross of heavy wood over it. Others boil the weld in the liquor, till the water has imbibed all its colour, and the drug sinks to the bottom, when the stuff is suspended in a net : others, again, take die weld out, as soon as it is boiled. According to the shade required, odier vege- tables are occasionally mixed with that drug. By varying the pro- portions of the salts employed, as well as the quantity of colouring ingredients, and the time of boil- ing, different shades may be pro- duced. The fourth primitive colour is that denominated by dyers the
