To Dye Cotton Or Woollen Black.

To each pound of yarn, have one ounce of copperas, nine of logwood, a

handful of salt, and a quart of good vinegar, which boil with copperas

ten minutes in a brass kettle; shave the logwood, and boil it in an iron

pot; when the color is extracted, strain it into the vinegar; put in the

yarn, and let it simmer twenty minutes stirring it; then hang it in the

air, and if it is not black enough, boil it over. You should have a

clear day to do all coloring in.
