(13) Ivory black, 2 lb.; molasses, 1 lb.; olive oil, 1/4 lb.; oil of vitriol, 1/4 lb. Add water to gain required consistency.

(14) Take 1 part ivory black, 1/8 of melted tallow, and work up well in a mortar. Incorporate with this paste part treacle, 1/4 of sulphuric acid, and 1/8 of spirits of salt. This will form an excellent paste blacking.

For application to dress boots the following compositions are prepared: - (1) Gum arabic, 8 oz.; molasses, 2 oz.; ink, 1/2 pt.; vinegar, 2 oz.; spirit of wine, 2 oz. Dissolve the gum and molasses in the ink and vinegar, strain, and then add the spirit of wine.

(2) Mix together the whites of 2 eggs, 1 teaspoonful spirits of wine, 1 oz. sugar, and as much finely pulverised ivory black as may be required to produce the necessary shade of black. Apply with a sponge, and polish with a piece of silk.

(3) Mix together 1/2 lb. each ivory black, purified lampblack, and pulverised indigo, 3 oz. dissolved gum arabic, 4 oz. brown sugar, and 1/4 oz. glue dissolved in 1 pint water; heat the whole to a boil over a slow fire, then remove, stir until cold, and roll into balls.

Harness blacking; is not made in the same way as boot blacking. The following are some of the methods of preparing the former kind : -

(1) Glue or gelatine, 4 02.; gum arabic, 3 oz.; water, 3/4 pint. Dissolve by heat, and add of treacle, 7 oz.; finely powdered animal charcoal, 5 oz.; and then gently evaporate until the compound is of the proper consistence when cold, stirring all the time. It must be kept corked.

(2) Mutton suet, 2 oz.; beeswax, 6 oz.; melt them, and add sugar candy, 6 oz.; soft soap, 2 oz.; lampblack, 2 1/2 oz.; finely powdered indigo, 1/2 oz. When thoroughly intermixed, add oil of turpentine, 1/4 pint.

(3) Beeswax, 1 lb.; animal charcoal, 1/4 lb.; Prussian blue, 1 oz.; ground in linseed oil, 2 oz.; oil of turpentine, 3 oz.; copal varnish, 1 oz. Mix them well, and form the mass into cakes while it is still warm.

(4) Add to No. 3, while still warm, soft soap, 4 oz.; oil of turpentine, 6 oz.; pat into pots or tins while warm.

(5) Isinglass, 1/4 oz.; finely powdered indigo, 1/4 oz.; soft soap, 4 oz.; glue, 5 oz.; logwood, 4 oz.; vinegar, 2 pints; ground animal charcoal, 1/2 oz.; beeswax, 1 oz. Infuse the logwood in the vinegar for some time with gentle heat, and when the colour is thoroughly extracted strain it, and add the other ingredients. Boil till the glue is dissolved, then store in stoneware or glass jars. Said to be very useful for army harness.

(6) Melt 4 oz. mutton suet with 12 oz. beeswax, 12 oz. sugar candy, 4 oz. soft soap dissolved in water, and 2 oz. finely powdered indigo. When melted and well mixed, add 1/2 pint turpentine. Lay it on with a sponge, and polish with a brush. A good blacking for working harness, which should be cleaned and polished with it at least once a week.

(7) 3 sticks black sealing-wax dissolved in 1/2 pint alcohol, and applied with a sponge; or lac dissolved in alcohol, and coloured with lampblack, answers the same purpose. This is intended for carriage harness; it is quick drying, and hard and liable to crack the leather, so should be applied as seldom as possible.

(8) A good blacking consists of: - Hogs' lard, 4 oz.; neats'-foot oil, 16 oz.; yellow wax, 4 oz.; animal charcoal, 20 oz.; brown sugar, 16 oz.; water, 16 oz. Heat the whole to boiling, then stir it until it becomes cool enough for handling, and roll it into balls about 2 in. in diameter.

(9) Soften 2 lb. glue in 1 pint water; dissolve 2 lb. soap (Castile is the best, but dearest) in 1 pint warm water; after the glue has become thoroughly soaked, cook it in a glue-pot, and then turn it into a larger pot; place this over a strong fire, and pour in the soap water, slowly stirring till all is well mixed; then add 1/2 lb. yellow wax cut into slices; let the mass boil till the wax melts, then add 1/2 pint neats'-foot oil and sufficient lampblack to impart a colour; let it boil a few minutes and it will be fit for use.

(10) When harness has become soiled it can be restored by the use of the following French blacking : - Stearine, 4 1/2 lb.; turpentine, 6 3/4 lb.; animal charcoal, 3 oz. The stearine is first beaten into thin sheets with a mallet, then mixed with the turpentine, and heated in a water bath, during which time it must be stirred continually. The colouring matter is added when the mass has become thoroughly heated. It is thrown into another pot, and stirred until cool and thick; if not stirred, it will crystallise, and the parts will separate. When used, it will require wanning; it should be rubbed on the leather with a cloth, using very little at a time, and making a very thin coat. When partially dry, it is rubbed with a silk cloth, and will then give a polish equal to that of newly varnished leather, without injuring it in any way.

(11) 2 oz. shellac, 3 pints alcohol, 14 1/2 pints fish oil, 19 pints West Virginia oil, 1 lb. lampblack, 1 pint spirits of turpentine, 9 pints coal oil; the two first are combined, then the third is added, and all the others are well mixed.

(12) Heat together over a slow fire, 2 oz. white wax and 3 oz. turpentine; when the wax is dissolved, add 1 oz. ivory black and 1 dr. indigo, thoroughly pulverised and mixed; stir the mixture until cold. Apply with a cloth, and polish with a shoe-brush.

(13) An excellent oil for farm and team harness is made of beef tallow and neats'-foot oil as follows: - Melt 3 lb. pure tallow, but do not heat it up to a boil; then pour in gradually 1 lb. neats'-foot oil, and stir until the mass is cold; if properly stirred, the two articles will become thoroughly amalgamated, and the grease will be smooth and soft; if not well stirred, the tallow will granulate and show fine white specks when cold. The addition of a little bone-black will improve this oil for general use'.

(14) Melt together 8 oz. beef suet, 2 oz. neats'-foot oil, 2 oz. white wax, and 2 oz. pulverised gum arabic; add 1 gill of turpentine, and sufficient bone-black to give the whole a good colour; stir until thoroughly mixed, remove from the fire, continue to stir until cold, then roll into balls. To apply, warm the ball, rub it on the leather, and polish with a woollen cloth.
