mordant to fix his dye, it appears that the color of flannel and silk 

 stained with the juice, could never be entirely washed out ; that 

 the sulphate of alumine, or alumine alone, and the niurio-sulphate 

 of tin, are tolerable good mordants for flannel, cotton, silk and linen. 

 Murio-sulphate of tin was the only mordant that fixed the color on 

 cotton and linen. I have heard that this plant was employed as a 

 dye, in some of the woollen-cloth manufactories in Delaware. If 

 success has been obtained in fixing the color permanently, there can 

 be no doubt that the dye obtained from this root will become a 

 highly-important article in domestic manufactures. It is said that 

 in IMaryland, the farriers give the root of Sa7igxiinana to horses, to 

 induce sweating, and to promote the shedding of their old coats of 

 hair.
