aforesaid contained in any one of the said colliery safety lighters shall not exceed 5 grains. Provided, also, that the 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 collodion 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 undermentioned 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 amores, 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, india-rubber, cement, coal-tar, saltpetre, naphthalene, and paraffin wax, and having attached thereto a strand of quickmatch.

INCENDIARY SHELLS.—Consisting of shells adapted for use in cannon, containing incendiary stars as above defined, with or without a bursting charge of gunpowder.

LIGHTNING-PAPER.—Consisting of thoroughly purified nitro-cellulose, with or without the admixture of a safe and suitable colouring material.

MAGIC CANDLE PIN-CRACKERS. —Consisting of thoroughly purified fulminate of silver, gummed or otherwise attached to a pin, and protected by a coating of paper, in a proportion not exceeding 15 grains of such fulminate of silver to every 1,000 magic candle pin-crackers.

MANUFACTURED FIREWORKS.—Consisting of any explosive of the foregoing classes, and any firework composition, when such explosive or composition is enclosed in any case or contrivance, or is otherwise manufactured so as to form a squib, cracker, serpent, rocket (other than a war-rocket), maroon star, lance, wheel, Chinese fire, Roman candle, or other article adapted for the production of pyrotechnic effects or pyrotechnic signals or sound-signals: Provided that a substantially constructed and hermetically closed metal case containing not more than 1 lb. of coloured-fire composition of such a nature as not to be liable to spontaneous ignition shall be deemed to be a manufactured firework.
