5. TO DYE FEATHERS DARK RED AND PURPLE. 



Hackles of various colours, boiled (without 

 alum) in an infusion of logwood and Brazil wood 

 dust until they are as red as they can be made 

 by this means, may be changed to a deeper red 

 by putting them into a mixture of muriatic acid 

 and tin, and to a purple by a warm solution of 

 potash. As the muriatic acid is not to be satu- 

 rated with tin, the solution must be much diluted. 

 If it burns your tongue much, it will burn the 

 feathers a little. 



6. TO DTE RED HACKLES A CLARET COLOUR. 



Boil a tea- spoonful of Brazil wood in half a 

 pint of water, and simmer some lightish furniss 

 hackles in this for a quarter of an hour. Then 

 take them out and immerse them in muriate of 

 tin, with the addition of a little muriatic acid. 

 Wash and dry. 



7. TO DTE FEATHERS VARIOUS SHADES OF RED, AMBER, 

 AND BROWN. 



First boil them in the alum mordant (see No. 

 1 ) ; secondly, boil them in an infusion of fustick 

 strong enough to bring them to a bright yellow 

 (about a table -spoonful to a pint of water), .then 

 boil them in a dye of mather, peach wood or 

 Brazil wood. To set the colour, put a few drops 

 of "dyer's spirit" (i.e nitrate of tin combined
