facilities for transporting e liquor of flint, the solvents
are desiccaed and used over again. II viii be observed
that this boiler is constructed with view to resist
heavy pressure, its bottom being of boiler iron, and
its sides of eitto shape, twelve feet high and
eight feet diameter; the bottom of saucer shape, OF

with natural pre- and is most suitable for working

boiler is set in masonwork with it's bottom in due.
One end Of pipe is connected with the said boiler

the upper end of vertical hollow shsft, which is
placed centrally in the boiler, with its closed lower end

passes through stuing box in the top plate of the

at the back Of the scraper.
The boiler ID also provided with main Tor chargng)

water vesse for the purpose of condensg the vapors
from the boiler when permitted to enter the said pipe
by Q valve and when condensed the contents OF the
