FAWN COLOURS. 407 



cultivated throughout India, Egypt, Palestine, and 

 Persia. The flowers generally come forth from May 

 to August. The leaves are the only part used ; these 

 are gathered, and after being hastily dried and bruised 

 to a pasty substance, are made to yield by boiling the 

 rich colouring matter in which they abound. 



Many British plants produce a brown colouring 

 matter, but not in sufficient quantities to render their 

 use extensive. 



The juice of the stems of hops affords a very durable 

 brownish red colour. Sloe-juice imparts a pale-brown 

 tint, which washed several times with soap, and then 

 moistened with an alkaline solution, becomes of a 

 deep red-brown. On boiling sloes their juice changes 

 to a red colour, and the dye which it imparts to linen, 

 when washed with soap, is converted into a bluish 

 colour, which is permanent.
