ed-to agreen; butthe goodnefs of the green depended 
on that of the blue. There are other fubftances which 
die a yellow colour, and with which the Indigo will form 
a green; butas they are found to be inferior to the radix 
jlava, or Yellow-Root, in making a yellow, and with the 
Indigo a green, nothing need be faid of them. 
In making their green the Indians difcover great ceco- 
nomy. They carefully unravel fmall pieces of green cloth, 
and pieces of old green garments. ‘Thefe they throw in- 
toa kettle with a fufficient quantity of water, and the cloth 
to be died. The whole is then fet over a gentle fire, un- 
til the colour is made. They informed me that by this 
procefs they die their Porcupine-quills green. 
The dlues are fo well known to be made by the Indigo 
of our own continent that nothing need be faid concern- 
ing them here. Under this head, however, I beg leave 
to obferve, that the Woad is the natural produce of our 
weftern foil, and that without it no deep or lafting blue 
can be made. 
The Indians die their d/ack with the Sumach of this 
country. They, likewife, make a beautiful black with the 
bark of the White-Walnut, and the vegetable-acid; for they 
have no knowledge of the mineral acids. With this bark 
T have feen them die'their woolen cloths, and the intefti= 
ties of various fpecies of animals, as bears, &c.
