Improvements in and in the Manufacture of Chemical Manure.
We, CHRISTOPHER GEORGE THOMAS DIXON, of Poplar Grove, Clock Face,
St. Helens, in the County of Lancaster, Analytical Chemist, and JoHN CRONE,
DAVID CRONK TAYLOR, and FRANK WILLIAMS, of Sutton Oak, St. Helens, in
the County of Lancaster, Chemical Manure Manufacturers, do hereby declare
the nature of this invention to be as follows:--
Our present invention has reference to a new or improved chemical manure
which we manufacture as follows;-
We take equal or approximately equal parts by weight of rock phosphate
and the clinker or slag produced in the working of destructors such as are
used for burning town refuse, and reduce them to a comparatively fine powder;
difficulty is experienced in grinding rock phosphate alone, but the admixture
with the slag facilitates the process materially, and we accordingly proceed as
follows:-
The rock phosphate and the slag are first roughly crushed, preferably indi-
vidually, and are then mixed in the desired proportions and ground together
to the necessary degree of fineness.
Although neither rock phosphate in its natural condition nor destructor slag
are suitable individually as a manure, we find that the product above described
formis an economical and readily assimilable manure of excellent quality.

forms an economical and readily assimilable manure of excellent quality.
Having now particularly described and ascertained the nature of our said in-
vention, and in what manner the same is to be performed, we declare that what
we claim is:-
The improved chemical manure which consists of approximately equal parts
of rock phosphate and the clinker or slag from refuse destructors ground
together to the necessary degree of fineness: substantially as described.
