In this calico two engravings are employed. The deep 

 colour and the white objects are printed at once, by 

 two copper rollers, in the same machine : the white being 

 the lemon juice already described, thickened with gum- 

 senegal. After this another roller applies the ground work 

 over the whole piece with a solution of iron. The iron 

 becomes fixed on the cloth every where except where the 

 acid has been applied, which remains white. 



18. Turkey-Red and White Bandanas. 



The word bandana has been appropriated to cotton printed 

 pocket handkerchiefs. By far the most beautiful and the 

 best known of these are the Turkey-red dyed handkerchiefs, 

 with white spots, stars, or crosses, such as the specimen 

 now presented to the reader.
