NOW KNOW YE, that I, the said Joseph Lallemand, do hereby
declare the nature of my said Invention, and in what manner the same

page_text: is to be performed, to be particularly described and ascertained in and
by the following statement.
The material I employ is peat or turf, and I treat it in the following
manner:
I first wash it thoroughly in order to separate all the carthy from the
fibrous portions, and I place these latter in a bath of caustic ley.
After a lapse of some twenty-four hours, more or less, according to
the strength of the ley, the fibres are removed, and are then placed for
about four hours in a bath acidulated with hydrochloric acid, and kept
constantly agitated therein.
The fibres are next washed in fresh clear water, and are then
subjected to a bath containing a small quantity of alum. The fibres
are then bleached in a chlorine vat, and are mixed with 5 to 10 por
cent. of rag pulp. The fibres and pulp are then placed in an ordinary
pulping engine, and the pulp goes through the processes usually
followed in the manufacture of paper.
And having now described the nature of the said Invention, and in
what manner the same is to be performed, I declare that what I claim
as of my said Invention is, the manufacture of paper from peat, as
herein-before described.
In witness whereof, I, the said Joseph Lallemand, have hereunto
set my hand and seal, this Fourth day of February, One
thousand eight hundred and fifty-four.
