SCARLET.
Wash and rinse your feathers thoroughly, and if required to remove a surplus of any old color, pass through a bath of permanganate of potash, as per recipe; after which prepare a bath of half a teaspoonful of oxalic acid to one gallon of boiling water and about a teaspoonful of turmeric; enter feathers and let them remain in bath about half a minute, after which take them out and add to bath about half a teaspoonful of rocceline; dissolve powder thoroughly, and return to bath; let them remain in about one minute longer, then cool off a small quantity of the bath and add a small handful of starch; pass your feathers through, squeeze out and dry as usual.
If wanted a very dark shade, add a little more rocceline and let remain longer in bath. If shade be a little on the orange, use more turmeric and less rocceline; and if more on the cardinal, vice versa. Should you, through carelessness, get your color too dark, to remove color rinse off and wash thoroughly in a soap bath, and rinse off in boiling water about twice, which will have the effect of reducing the color several shades; mix a new bath as per recipe, and enter feathers, using more care and judgment and proceed to starch and dry as called for in recipe.
