A Process for Rendering Waste Leather Soluble and applicable as
a Manure..
I, JOSEPH HUDSON, of No. 29 Red Lion Street, Clerkenwell, in the County
of London, Manure Manufacturer, do hereby declare the nature of this invention
to be as follows:-
My invention relates to means of rendering waste leather soluble, so as to adapt
it for manuring.
For this purpose, 1 thoroughly soak the waste leather with water in which
barm or other ferment is dissolved and spread it out over a floor, and I add
successive layers until fermentation is set up. The material thus treated, after
standing for several weeks, becomes mostly soluble so that it can be used as a
valuable manure but for convenience of transport I prefer to dry and pulverise the
fermented mass so as to pack it in a solid coudition.
Dated this 4th day of January 1896.

A Process for Rendering Waste Leather Soluble and applicable as
a Manure.
I, JOSEPH HUDSON, of No. 29 Red Lion Street, Clerkenwell, in the County
of London, Manure Manufacturer, do hereby declare the nature of this invention
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :--
My invention relates to means of rendering waste leather soluble, so as to adapt
it for manuring.
Waste leather contains a large amount of nitrogen in an insoluble form and I
bave discovered that if such leather be subjected to a process of fermentation the
nitrogen is converted into soluble substances, and is thus brought into a condition
in which it becomes of great value a a manure. To effect this change, I
thoroughly soak the waste leather with water in which barm or other ferment is
dissolved and spread it out over a floor, and 1 add successive layers until
fermentation is set up.
Under suitable conditions as to heat and moisture fermentation will take place
without requiring extraneous ferment, but in order to ensure fermentation, it is of
advantage to employ a portion of the leather which is already fermented to start
fermentation of a subsequent batch.
A convenient method of operating in this way is to put a portion of leather
already fermented in the midst of a heap of unfermented leather which has been
soaked in water. As the heap becomes heated and fermented, more of the soaked
leather is piled upon it, until the beap attains such size as may be convenient, and
the mass is allowed to remain until fermentation is completed.

page_text: The material thus treated, after standing for several weeks, becomes mostly
soluble so that it can be used as a valuable manure, but for convenience of
transport. I prefer to dry and pulverise the fermented mass so as to pack it in a
solid condition.
Ilaving now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what
I claim is :-
1. The herein described process for rendering waste leather soluble and
applicable as a manure by soaking the leather in water and subjecting it to
fermentation.
2. A manure consisting wholly or partly of leather fermented as above set
forth.
