I doubt not, but that if thefe two trees of Caro- 
lina were of their proper height, they would pro- 
duce as fine a colour as this laft fiirub. However, I 
put the linen marked with the three black fpots in- 
to a boil of foap, and it came out without the leaft 
diminution of the colour of the fpots. When this 
linen was dried, I threw it into a ftrong lye of the 
alhes of green wood j and it, in like manner, came 
out without the leaft alteration of the three ftiades 
of the fpots, produced by the three plants men- 
tioned. 
I took a handful of the leaves of the Toxicoden- 
dron glabrum^ to try if it might be of ufe in dying ; 
and made a very ftrong decoftion of it j and while it 
was boiling 1 dipped linen in it : it was tinged 
green, but, befides its not being a good green, the 
whole furface was unequally coloured j for I ob- 
ierved feveral places took a fine black : whence I 
concluded, that the refinous juice of the internal 
parts of the plant was the only part capable of pro- 
ducing the defired eftedl. I was confirmed in this 
notion, after having let my decodtion fettle ; it firft 
let fall a black refinous juice in fmall quantity, like 
the opium of our fhops : then a large quantity of a 
white fediment like a fait, which was quite taftelefs 
upon the tongue. In fhort, the water appeared greenifti 
above, and blackifti towards the bottom of the 
veflel. 
I fhould have been glad to try fome experiments 
upon the Roots of this plant; but, as there was only 
one in the garden, I was afraid of injuring it. Per- 
haps the fruit or feeds might produce fome kind of 
dye.
