To dye cotton skein a DUCK'S WING GREEN and OLIVE.

It would answer little purpose to enlarge this treatise with a detail of all the possible methods of producing the various shades of these several colours, the whole consisting in the use of galls, verdigris, sulphate of copper, weld, and madder.

By welding a stuff previously maddered for red you may produce a gold colour; and by dipping the same red in a blue vat you obtain a plum colour.
