Protector Oettinger at Tubingen made,
long ago, in fnall publication which ap-

have led to the fecret Of the oriental pro-
cefs for dyeing with madden. He there
remarked that the beautiful dye of the

that either the dye irfelf, or the preparing

The greater part Of the fix and cotton
manufactures at Afracan are carried on by
Armenians, the number Of whom on ac-
count Of the troublefome fate Of Peria is
continually increaing; and the dye-hou-.
les are kept going only from the frit warm
days in the fpring till towards the end of
autumn. The macder they employ comes
partly by land over Kirzlar from Terek,
and partly by fea over Derbent from the
Perfian Gillian. In both places the plants
grow wild in the fields in great album
dance and great perfection, and is dug Up
alto in the uncultivated meads. The roots
are generally as thick as the barrel of a
quill, fometimes as ones finger, and
throughout the whole fpongy part ofan a
greeable pale red colour the bark or the
other hand is for the mott part very thin,
and appears to be Of little value.
AT Terek the frefh gathered roots, are
placed above each other in fove, or IN
a pit dug of Vicious earth which has been
frongly heated. Earth is then thrown
over the madder, and il niuR iweat until
the aoye or pit becomes cold when the
roots, the fecond or third day, are taken
from it, and either fpread out or hGag up
to dry. The fame proceis is uiual alto in
Perfa, and abundance of madden is bro't

to The importation, at from four to feven
rrbles FOX every forty poends.
