An Improved Compound for Destroying Rats and other like Pests.
I, ROBERT PAUL, of Siegburg, in the Province of the Rhine, German Empire,
Druggist, do hereby declare the nature of this invention to be as follows:-
The subject of this invention hereinafter described, refers to a compound, and
process for manufacturing the same, for destroying rats, mice and other like pests.
the said compound being harmless to human beings and domestic animals. The
rat banes commonly known and used have the great disadvantage that they are
poisonous for other living bodies, especially for children and domestic animals.
To prevent this I employ substances which are perfectly free from any poisonous
matter for living bodies other than the pests referred to, the sea-leek being the
killing substance employed. To induce rats, mice, and the like to eat the sea-
leek, and to preserve the compound from decomposition it is prepared with other
substances as hereinafter described.
The sea-leek is a herbaceous plant belonging to the species "Urginea," its
technical name being "Scilla maritima" and grows on the coasts of the Mediterra-
nean and the Atlantic Ocean, and for the purposes of this invention the bulbous
root of the plant is used, this being found the best portion to obtain the results
desired.
The sea-leek is cut into small pieces or shreads, and mixed up with heated
grease or tallow, and to this is added bruised rye, bran of wheat, waste of con-
fectionary (cakes etc.) and pepper and salt in suitable proportions. The different
ingredients are then thoroughly mixed together, and in order to preserve it from
decomposition, this mixture is then treated with pyroligneous acid and alcohol,
and afterwards filled into guts or skins after the manner of sausages, which are
again dipped in pyroligneous acid to remove the superflous water, and finally
smoked for about 70 hours. The resulting sausages or packages can be kept for
a year or more and still be used with good results for the purposes stated.
The afore described preparation of the sea-leek, especially with alcohol, pyro-
ligneous acid, pepper and salt is very important, because only in this manner
is it possible to obtain (in co-operation with the other part of the process) a useful
and durable manufacture which is harmless for human beings, as well as domestic
animals, and which serves admirably as a bait for rats and mice. The latter would
not eat the sea-leek unless mixed with the said substances. It has been tried
formerly to add groats to the sea-leek, but this does not make a compact well
mixed substance, while rats and mice would eats the groats only, and leave the
sea leek which is the destroying agent.

I, ROBERT PAUL, of Siegburg, in the Province of the Rhine, German Empire,
Druggist, do hereby declare the nature of this my invention, and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
The subject of my invention, hereafter described refers to a compound and a
process for manufacturing the same for destroying rats, mice and other like
pests, the said compound being harmless to human beings and domestic animals.
I therefore only employ substances which are perfectly free from any poisonous
matter for living bodies, other than the-pests referred to. The killing substance
employed is the sea leek.
To induce rats, mice and the like to eat the sea leek and to preserve the com-
pound from decomposition it is prepared with other substances as hereafter
described, in the proportions stated or thereabouts. The sea leek is a herbaceous
plant belonging to the species "Urginea," its technical name being "Scilla mari-
tima
"and grows on the coasts of the Mediteranean and the Atlantic Ocean, and
for the purposes of this invention the bulbous root of the plant is used this being
found the best portion to obtain the results desired.
The 7 parts of sea leek is cut into small pieces or shreds and mixed with
2 parts of heated grease or tallow and to this is added 3 parts of bruised rye
2 parts of bran of wheat 2 parts of waste of confectionery (cakes etc.) 30 parts of
pepper and 200 parts of salt. The different ingredients are then thoroughly
mixed together, and in order to preserve it from decomposition this mixture is then
treated with 100 parts of pyroligneous acid and 150 parts of alcohol the whole
These
being afterwards filled into guts or skins after the manner of sausages.
sausages are then heated to about 370 to 380 degrees Fahrenheit, in order to
preserve them from decomposition so that they can be kept for a year or more
and still be used with good results for the purpose stated.
The afore described preparation of the sea leek especially with alcohol, pyro-
ligneous and pepper and salt is very important, because only in this manner is it
possible to obtain (in co-operation with the other part of the process) a useful
and durable manufacture, which is harmless for human beings as well as domestic
animals and which serves admirably as a bait for rats and mice. The latter
would not eat the sea leek unless mixed with the said substances. It has been
tried formerly to add groats to the sea-leek, but this does not make a compact well
mixed substance, while rats and mice would eat the groats only and leave the
sea-leek, which is the destroying agent.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed I declare that what
I claim is:
1. In a process for manufacturing a compound for destroying rats mice and other
like pests the mixture of the sea-leek with heated grease or tallow, substantially
as described.
2. In a process for manufacturing a compound for destroying rats, mice and
other like pests the mixture of the sea leek with bruised rye and bran of wheat,
substantially as described.
3. In a process for manufacturing a compound for destroying rats, mice and
other like pests, the treatment of said compound with alcohol and pyroligneous
acid as and for purpose specified.

page_text: 4. In a process for manufacturing a compound for destroying rats, mice and
other like pests, the way of preserving the sea-leek from putrefying by heating
it to a temperature of about 370 to 380 degrees Fahrenheit, substantially as
described.
