_To make liquid blue._—A pound of the oil of vitriol and an ounce of the best Spanish indigo pounded very fine and sifted; pour the vitriol into a three-pint delft bowl, put the indigo in, and stir it with a clean stick for half-an-hour; add of soft water by little and little one pint, stirring it all the time till the fermentation is over; then bottle it for use. This gives the finest blues and greens, _but they fade_; you are not to touch your blueing vat with any thing that is yellow. _For blues._—You ought to get the finest of whites, and prepare them well; have the urine vat in good order. Stir up the vat, throw in the feathers in as many bunches as you intend to have shades; lift them out now and then to strike the air. When a middling bright blue, take out a bunch; let the second lie in for double the time and more, and air them as directed. When you see a fine full blue, take out another bunch. You may let the third bunch lay in for two or three days; but as soon as you take out each bunch, you should have about six drops of solution blue in a bowl with a pint of boiling water; rinse them well in that, and it will clean them. If you see it wants it, add in a few drops more, and it will still add to the brightness. Put them instantly into cold water, and wash them well. Do the same three or four times; thus you will have fine deep blues, bright and fast. _Powder blues._—Follow the same process, but do not leave them till done; draw and air them every half-hour; and when of a proper colour, have some boiling water, and from four to six drops of solution to rise and brighten them; and if you see it requires it, add a few drops more. Wash, &c., as before. _A very bright blue._—Ground richly with an archill. Wash in stale urine; put your feathers into the urine vat for half-an-hour; take out and air them, and do as with all the rest.
