TO DYE SCAKLET. 



Boil your hackles, &c., in a little crystal of 

 tartar; procure two table-spoonfuls of cochineal, 

 bruise them a little, and boil them gently over 

 the fire for an hour or two ; take the hackles 

 you have just boiled in the tartar, and put them 

 into the dye-pot, and simmer them slowly for 

 some time, say half an hour ; then take your 

 "spirits of grain,"* and put into the dye-pot a 

 tea-spoonful or a little more ; take them out 

 occasionally, and look at them between your 

 eyes and the light, and when the right shade 

 is obtained, rinse them and dry. 



If you are in a hurry for scarlet, you may 

 drop the particles of block-tin into aqua-fortis 

 till they are dissolved, and add a little to the 

 scarlet dye ; the other is best, as it gives a more 

 brilliant shade ; — boil slow. 



If the extract of bismuth is added to the 

 red liquor of the cochineal in a small quantity, 

 it will change it to a purple or violet colour. 



* Spirits of grain for scarlet, — a quarter pint of spirits 

 of nitre, a quarter of an ounce of ammoniac, add half 

 \ water in a bottle, and drop into it half an ounce of X 

 ^ block-tin in grains till dissolved. ^
