BLUES. 



Dissolve some indigo in oil of vitriol for 

 twenty-four hours, put a couple of spoonfuls 

 in your pot, add a little crystal of tartar, put 

 in your hackles and boil, or at least keep them 

 at a scalding heat, or the vitriol will bum the 

 feathers, furs, &c., take them out, rinse them 

 well, and the colour will be lasting. 



If to the above liquor some fustic chips, well 

 boiled by themselves, and the juice added, you 

 may then have any shade of the best green. 



A SILVER GREY. 



Boil some fenugreek and a little alum half an 

 hour, put in the white hackles, &c., and add 

 a little pearlash and Brazil-wood, boil them 

 gently an hour, rinse them, and your colour 

 will be lasting.
