is it so bright as the yellow, which can be more 

 cheaply obtained from quercitron bark. Four pounds 

 of this chipped wood affords no more colouring 

 matter than one pound of quercitron. This dye- 

 wood is seldom used alone ; it is employed merely 

 as an accessary colour to heighten cochineal and 

 other dyes, and to give them an approach to a yellow 

 tinge. 



Venetian sumach was long distinguished in France 

 by the name of Fustet, and, with the wood, the name 

 somewhat altered into fustic, was introduced into 

 England. The. wood of the morus tinctoria was 

 subsequently brought from America, arid likewise 

 employed for dyeing yellow ; destitute of a name, the 

 American wood also acquired that of fustic, as being 

 like it a yellow dye-wood. A confusion having con- 

 sequently arisen to distinguish them, the wood of 

 the shrub was called young fustic and that of the 

 large American tree which is always imported in the 

 form of large blocks or logs, old fustic. Many per- 

 sons have in consequence been misled so far as to 

 conclude that two very distinct dyeing drugs were the 

 same, differin'g with each other only in point of age. 



The wood known in England by the name of 

 green ebony possesses a species of colouring matter 

 very similar to that of moms tinctoria, and is some- 

 times employed in its stead in dyeing. 



Among the American trees which yield a yellow 

 dye, the Hiccory, or Juglans alba, may be enumerated. 

 This is a species of walnut-tree producing nuts some- 

 what similar, but very inferior in every respect to the 

 common walnut. The bark, the green leaves, and 

 the rind of the nuts yield an adjective yellow colour. 

 This dye is similar to that produced from quercitron, 

 differing only in containing about one-third less 

 colouring matter in a given weight. The grinding of
