The following are instructions on dyeing sheepskins black, grey, and brown. After the skins are dressed and softened they should be placed in the hot dye, wool downwards, and allowed to remain for an hour or two. They should then be washed in cold water, and hung up to dry till the next day. They should then be put into the hot fixing solution, allowed to remain an hour or two, washed in cold water, and hung up to dry. As it is only necessary to immerse the wool in the solutions, some strips of wood can be placed along the bath containing the dye to prevent the skin sinking. Take great care that the solutions are hot when used, and, during the drying, frequently shake the skins and rub them to prevent them drying hard. For a black, boil 3/4 lb. of cop-neras, 2oz.of sulphate of copper, and lib. of cream of tartar in 1gal. of water. This is the fixing bath. The dye is made by boiling.5lb. of logwood in 1 gal. of water for a grey dye, boil .'lb. of logwood in lgal. of water; for the fixing bath, boil 2oz. of copperas in 1 gal. of water. To make a brown dye, boil llb. of catechu in lgal. of water; and for the fixing bath, boil 1/2 lb. of sulphate of copper in lgal. of water. These proportions may be varied according to the tint desired.

The operations may be repeated if the colour is not intense enough. Experiment first upon a piece of skin.
