PROVISIONAL SPECIFICATION left by the said Edward Charles
Hamilton and William Richard Preston at the Office of the Com-
missioners of Patents, with their Petition, on the 16th July 1873.
We, EDWARD CHARLES HAMILTON, of Colchester, in the County of
Essex, and WILLIAM RICHARD PRESTON, of Harold Court, Romford, in
the County of Essex aforesaid, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN THE MANUFACTURE OF ARTIFICIAL MANURE,
AND IN APPARATUS EMPLOYED THEREIN," to be as follows:-

page_text: or shoddy, and we mix it with liquid sewage in the proportion of equal
weights or thereabout. We pass the mixture into a machine consisting
of a cylinder or barrel through which an axis passes. There are inclined
knives upon the axis, and other knives fixed within the cylinder or
barrel. The mixture is introduced by a hopper at one end of the
cylinder or barrel, and is discharged at the other end, and in this state
the materials constitute a valuable artificial manure in a form to be very
conveniently sown upon land.
In some cases we much increase the proportion of the sewage in
relation to the waste wool, wool dust, or shoddy, and in this case we
form the waste wool, wool dust, or shoddy into a filtering bed, and place
a layer of charcoal beneath it%3B the sewage is run on to the filter so
formed, the water passes through leaving the manurial constituents of
the sewage in the filter.
When the filtering materials are fully charged with the sewage they
are passed through the machine already described, and they form a rich
artificial manure.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edward Charles Hamilton and William Richard
Preston in the Great Seal Patent Office on the 15th January
1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, EDWARD

ARTIFICIAL MANURE, AND IN APPARATUS EMPLOYED THEREIN," upon the con-
dition (amongst others) that we, the said Edward Charles Hamilton
and William Richard Preston, our executors or administrators, by an
instrument in writing under our or their hands and seals, or under the

declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement thereof, that is to say :—
This Invention has for its object improvements in the manufacture of
artificial manure. For this purpose we take waste wool, wool dust, or
shoddy, and we mix it with liquid sewage in the proportion of equal
weights or thereabout. We pass the mixture into a machine consisting
of a cylinder or barrel through which an axis passes. There are inclined
knives upon the axis, and other knives fixed within the cylinder or
barrel. The mixture is introduced by a hopper at one end of the
cylinder or barrel, and is discharged at the other end, and in this state
the materials constitute a valuable artificial manure in a form to be very
conveniently sown upon land.
In some cases we much increase the proportion of the sewage in
relation to the waste wool, wool dust, or shoddy, and in this case we
form the waste wool, wool dust, or shoddy into a filtering bed, and place
a layer of charcoal beneath it, the sewage is run on to the filter so
formed, the water passes through leaving the manurial constituents of
the sewage in the filter.
