UNITED STATES PATENT OFFICE.
JOSEPH B. CARMICHAEL, OF BONITA, TEXAS.
SPECIFICATION forming part of Letters Patent No. 605,537, dated June 14, 1898.
Application filed February 28j 1898. Serial No. 672)071. (No specimens.)
To all whom, it may ConCer2:
Be it known that I, JosEPH B. CARMICHAEL,
a citizen of the United States, residing at Bo-
nita, in the county of Montague and State of
5 Texas, have invented certain new and useful
Improvements in Insecticides; and I do de-
clare the following to be a full, clear, and exact
description of the invention, such as will en-
able others skilled in the art to which it apper-
1o tains to make and use the same.
My invention relates to an insecticide com-
pound and one that is particularly intended
for the destruction of ants and the like bur-
rowing insects; and the object is to provide
[5 a compound for effectually exterminating this
class of vermin.
To this end my invention consists in the
combination of the ingredients hereinafter
more fully set forth, and particularly pointed
20 out in the claim.
In preparing my insecticide compound I
take cyanid of potash, one ounce; spirits of
camphor, one-half ounce; benzin, one-half
ounce; turpentine, three ounces; sulfuric
25 ether, two drams; oil of sassafras, one - half
ounce; oil of spike, one-half ounce; water,
sufficient quantity to make one pint. The
ingredients are added in the order named
above and the whole thoroughly mixed.
30 The manner of using the compound is as
follows: First dig a hole about ten (10) or
twelve (12) inches square and about as deep
over the ant-bed. Then in two or three days,
or as soon as the ants open up an exit in the
hole that has been excavated, saturate apiece 35
of cotton-waste about four (4) or five (5) inches
in diameter with the compound and place it
over the exit-passage. Then cover the satu-
rated cotton with earth and pack the ground
firmly to prevent the compound evaporating, 4o
so that the fumes or gases from the compound
will only escape through the passage-way and
permeate the bed or nest and effectually ex-
terminate the occupants.
Having thus fully described my invention, 45
what I claim as new and useful, and desire to
secure by Letters Patent of the United States,
An insecticide consisting of cyanid of pot-
ash, camphor, benzin, turpentine, ether, oil 5o
of sassafras, oil of spike, in about the pro-
portions hereinbefore set forth.
In testimony whereof I have hereunto set
my hand in presence of two subscribing wit-
JOSEPH B. CARMICHAEL.
