simmered over the fire till it has the consistence of soft 

 salve. This, applied with a piece of woollen, will give 

 a beautiful gloss to gun-stocks, furniture, &c. 



To Preserve Gun-barrels from Rust, occasioned 

 by Salt Water. 



Three ounces of black-lead, half a pound of hogs* 

 lard, and a quarter of an ounce of camphor, boiled over 

 a slow fire : the barrels to be rubbed with this mixture, 

 which, after three days, must be wiped off with a linen 

 cloth. This process need not be repeated above twice 

 in the winter. 



To Colour Gun- Barrels. 



One ounce of blue-stone vitriol, dissolved in a tea- 

 cupful of warm water, six ounces sweet spirit of nitre, 

 and one ounce tincture of steel (such as creates rust) ; 

 put these into nearly half a pint -of spring water: well 

 shake it, and it is fit for use. Let the barrel be pro- 

 perly cleaned, with a buff strap, or fine emery paper. 

 A little unslacked lime will take the oil or grease off; 

 then take equal quantities of spirit of salt, aquafortis, 

 and water ; shake it well, and rub the barrel with it ; 

 let it stand till next day: this is called pickling. Then 

 apply the mixture with a piece of soft rag; let it stand 

 one day, and rub it with a superfine steel scratch-brush, 

 repeating it till it comes to your mind. Wash the 

 barrel over with boiling water, and apply a little sweet 

 oil with alkanet.
