1600. Stir it well, put the feathers in, and let them simmer a few minutes.
1601. Yellow.—Put a tablespoonful of the best turmeric into a quart of boiling water; when well mixed, put in the feathers.

1603. Green.—Mix the indigo liquor with turmeric, and pour boiling water over it; let the feathers simmer in the dye until they have acquired the shade you want them. (See 289.)
