These species of Sumach are moderately astringent. An in- 

 fusion of the berries, sweetened with honey, is sometimes used 

 for a gargle in sore throats, and for cleansing the mouth in putrid 

 fevers. The country people employ them in several kinds of 

 dyes. With copperas or vitriol they give a good black ; but 

 it soon grows rusty. They are used in the preparation of 

 Morocco and other leather. Carver says, the Indians, in order 

 to render their tobacco more agreeable in smoking, mix with 

 it equal quantities of the leaves of Sumach,
