[Illustration: FIG. 4.--INFERNAL MACHINE FOUND ON THE "BAVARIA."] [Illustration: FIG. 5.--MACHINE OF THE 1881 PERIOD.] An 1882 relic is a most interesting one, and its surrounding companions are equally curious. Here is the revolver with which O'Donnell shot Carey (Fig. 6). It is of an American pattern, and marked 147A in the catalogue. A most ingenious contrivance also in this part of the collection is a tin can, made in two compartments (Fig. 7). It was used for conveying contraband gunpowder to Egypt. It is so made that when it is probed by the Customs' officials to see what it contains, the probe used comes out covered with oil. [Illustration: FIG. 6.--O'DONNELL'S REVOLVER.] A few samples of a not particularly choice brand of cigars are also shown (Fig. 8). A gentleman who has no great love for you, and who fully appreciates the weakness of human nature of the male persuasion in seldom refusing a cigar, offers you one out of his case:-- [Illustration: FIG. 7.--CANISTER FOR SMUGGLING GUNPOWDER.] "Something very choice, sir, I assure you," he says. He is a perfect stranger to you, but--well, a cigar's a cigar, and you accept his kind offer. The benevolent cigar proprietor sees you light up, and you puff away in peace. He is suddenly called away. The cigar explodes! It contains an explosive, which is wrapped up in a piece of blue paper, and is placed about half-way down the cigar. [Illustration: FIG. 8.--EXPLOSIVE CIGARS.] But the most interesting relic of 1882 is a little canister very much resembling a diminutive milk can (Fig. 9). It is supposed to contain dynamite, and has never been opened since its receipt at the House of Commons in that year, addressed to Mr. Forster, then Chief Secretary for Ireland. [Illustration: FIG. 9.--CAN SENT TO MR. FORSTER.] It was not, however, until 1883 that the authorities were fully aroused. The Explosives Act of 1875 had controlled all substances of this nature; but it was not designed to control the criminal use of explosives, although it is true that certain clauses were found available to some extent. But the Act of 1883 was passed by the House of Commons in a single sitting--a most important and far-reaching Act, which deals with every possible phase of the question of explosives. No wonder this Act was passed.
