the drum placed in the furnace, and imme- 
diately set revolving, and the cover shut 
down upon it: through the open end of the 
pierced axle-cylinder, aqueous yapour or 
steam will quickly begin to issue, and in- 
crease to a certain point, and then rapidly 
decrease in quantity, and will begin, at 
length, to be mixed with volatilized oily 
matters, driven off from the heated seeds ; 
which escape of the oily products is then 
to be checked and prevented, by diminish- 
ing and closing up this and the other exit 
from the drum. ‘The proper time for doing 
which, may be ascertained, the patentee 
says, by holding, from time to time, a piece 
of slate before the open end of the pierced 
cylinder, which will be merely wetted, as 
long as steam alone is escaping, but a gum- 
my substance beginning to condense on 
the slate, will shew when the drum ought 
to be closed and kept so, except during the 
instants of introducing the trial-spoon, as 
many times as.may be necessary, for ascer- 
taining the proper instant for removing the 
cover, and transferring the drum to the 
cooling place, there to be turned slowly on 
its axles, until the roasted contents are 
nearly cold; after which they should be 
preserved, as close and as dry as possible, 
until ground for use. 
By this apparatus, rye or other grain may 
be roasted in a very superior manner, malt 
dried, &c, 
To Tuomas Bury, of Salford, Lancashire, 
for an improved Nankeen Dye, for cotton, 
wool, &c.—18th February 1823. 
THE inyention and claim of this patentee 
consists in applying the bark of the cork- 
tree (quercus suber) for dyeing, instead of 
the woods heretofore used to obtain a nan- 
keen colour. About 12 Ibs. of the cork- 
tree bark is to be well bruised or crushed, 
and then macerated, a sufficient time, in 
about fourteen gallons of water, the decoc- 
tion from which will be sufficient for dyeing 
about 20 Ibs. of skein-yarn, cotton, or wool. 
After such goods have been prepared, with 
the well-known and usual mordant, for 
receiving a nankeen colour, applied dur- 
ing ten or fifteen minutes, they are 
to be washed, previous to rinsing them, 
for about the same space of time, in the 
cork-bark decoction; the usual second 
mordant, for this colour, is then to be ap- 
plied, for a like period; then the goods are 
to be washed in soap and warm water, or 
else in hartshorn and water, and they may 
then be dried and finished.
