To Dye Yellow
Put two table-spoonfuls of ground alum, and one tea-spoonful of cream of tartar into a pint of water. When perfectly dissolved and boiling, put in the feathers, hackles, or hair, and simmer for half an hour. Take them from this mordant bath, and put them in the yellow dye, made by infusing a table-spoonful of ground turmeric in a pint of water, and immersed until the color is extracted.
Boil until the color is deep enough, and then wash them in clean water. Dry, and dress them as directed.
There are several materials for yellow dyes, such as fustic, quercitron bark, yellow wood, Persian berries, and weld; but turmeric is the best for the purpose.
