said colliery safety lighters shall be of such strength and
construction that the ignition of one such colliery safety
lighter will not communicate laterally with others.

Detonators.—Consisting of a capsule or case of such
strength and construction, and containing an explosive of
the fulminate class in such quantity, that the explosion of
one capsule or case will communicate the explosion to
other like capsules or cases.

Electric Detonators.—Consisting of a detonator
having two insulated wires connected by a fine platinum
wire imbedded in a priming composition consisting of
chlorate of potash and sulphide of antimony, or purified
gun-cotton, and so placed and secured that no part of the
wires can come into contact with the fulminate in such
detonator.

Electric Detonator Fuses (Smith’s Patent).—Consisting of electric fuses as above described (see above in
Division 2), and having attached thereto a detonator as
above defined: Provided that no one such electric detonator
fuse shall contain more than 30 grains of explosive of the
Fifth (fulminate) Class.

Electric Detonator Fuses.—Consisting of electric
fuses as above described (see definition in Division 2),
inserted into a detonator, and so secured that the electric
fuse cannot come into contact with the fulminate in such
detonator.

Elswick Mechanical Tubes.—Consisting of a case of
metal, wood, paper, or other suitable material containing
its own means of ignition and a charge not exceeding 1 oz.
of gunpowder.

Fuses for Shell.—Consisting of cases of wood or
metal, or other suitable material, containing their own
means of ignition, and of such strength and construction
that the explosion of one fuse will not communicate the
explosion en masse to other like fuses.

High-tension Electric Detonator Fuses.—Consisting of high-tension electric fuses (see above in Division 2),
and having attached thereto a detonator.

Low-tension Electric Detonator Fuses.—Consisting of low-tension electric fuses as above described, and
having the platinum wire imbedded in a charge not
exceeding 2 grains of a priming composition consisting of
(a) carefully purified gun-cotton, or (b) carefully purified
colloidion cotton, and the case being fitted with a detonator.
—(No. 1 Definition.)

Low-tension Electric Detonator Fuses.—Consisting of low-tension electric fuses as above described (see
definitions Nos. 2, 3, 4, and 5, in Division 2), and having
attached thereto a detonator as defined by an order of the
Governor in Council.—(No. 2 Definition.)

Safety Firing Tubes No. 2.—Consisting of safety
firing tubes No. 1 (see above in Division 1), with the
addition of a priming charge of meal powder not exceeding
40 grains, the whole to be of such construction that the
explosion of one will not communicate to others in close
contact.

Spon’s Electric Detonator Fuses.—Consisting of
Spon’s electric fuses, as above described (see above in
Division 2), and having attached thereto a detonator as
above defined.

Tubes for Firing Explosives (other than detonators).—Consisting of cases of quill, metal, or paper, charged with
mealed powder or other suitable explosive, and containing
their own means of ignition.

Class 7.—Fireworks.

Division 1.

Firework Composition.—Consisting of any chemical
compound or mechanically mixed preparation of an explosive
or inflammable nature which is used for the purpose of
making manufactured fireworks and is not included in the
former classes of explosives, and also any coloured-fire
composition. Subject to the proviso hereinafter set forth.

Division 2.

Amorces (whether in the form of toy caps or igniting
tapes).—Consisting of dots of one or other of the under-mentioned compositions enclosed between two pieces of
paper, or separated by a sheet of paper or cardboard, in a
proportion not exceeding 70 grains of such composition to
every 1,000 dots.

Composition.—(a.) A mixture of chlorate of potassium
and amorphous phosphorus, with or without the addition
of—(1) Nitrate of potassium, sulphide of antimony, and
powdered sulphur (free from acid); or (2) chalk, rye, flour,
and resin (sandarak); or (3) manganese and glue; or (4)
such other substances as may from time to time be
approved by the Governor in Council: Provided that the
amount of amorphous phosphorus present in the mixture
shall in no case exceed the proportion of 10 grains in
1,000 dots.

Composition.—(b.) A mixture of chlorate of potassium
and ferrocyanide of lead.

Crack Shots.—Consisting of an amorce, composed of a
patch of thoroughly purified fulminate of silver enclosed
between two pieces of paper in a proportion not exceeding
15 grains of such fulminate of silver to every 1,000 amorces,
such amorce to be gummed to or form part of a sheet of
paper not less than 4 in. square, and having a strip impregnated with nitre.

Distress-signal Rockets—Consisting of sound signal-rockets as hereinafter described, with the addition in the
head of the rocket of one or more stars, composed of two or
more of the following ingredients, viz.: Nitrate of potash,
sulphur (carefully washed), realgar, antimony, gunpowder.

Incendiary Stars.—Consisting of cases of paper or
other suitable material, containing a mixture of gunpowder,
indiarubber, cement, coal-tar, saltpetre, naphthalene, and
paraffin wax, and having attached thereto a strand of
quickmatch.
