As to getting the case on board, it was as easy as could be. Having proceeded to New York in Marese’s yacht, taking with them the necessary apparatus for producing the gas (which was very simple), and pumping it into the case, they could ascertain the hour of the steamer’s departure, fill the case, regulate the acid for say four, or perhaps three days, and send it on board only a little while before she started. They would then, on board the yacht, proceed to sea on a cruise and keep the steamer in sight. Delightfully simple! Perfectly complete and scientific in every detail! Marese once again asked if the gas was really so powerful? Theodore referred to his note-books, and showed him an extract from a newspaper not of so very remote a date, wherein it was stated that at a conference of the various leading European Powers it had been resolved not to employ certain implements in warfare, such as explosive shells or bullets under a certain size, and poisonous gases or vapours which could be thrown into a fortress or town in shells. Marese was convinced, and regarded the engine as perfect. Thus did two men deliberately plan out the destruction of several hundreds of their fellow-beings without one single thought or reflection upon the misery and suffering they would cause, or upon the intrinsic villainy of the act. Well was it suggested by a French thinker that certain natures are incapable of feeling, incapable of remorse so long as they remain “faithful to the logic of their type”—i.e. faithful to their own selfish interests and passions. Chapter Fifteen. With his own hands Theodore constructed the infernal machine and prepared the materials for generating the deadly vapour at the shortest notice. This, the first part of the scheme, having been settled, there remained two great difficulties to overcome. The first was to get the claimants on board one vessel—travelling in a body; and the second was to secure their passage by a steamer carrying a valuable cargo, so as to increase the gain of salvage money to the utmost. It was not easy to manage the first matter; the latter Marese thought he saw his way through. It happened just then that the payment of the war indemnity to Germany caused a great drain of gold from this country; the value of the precious metals consequently rose, and the imports increased to meet the demand. Gold and silver came in large quantities from New York, both in coin and bullion—especially silver. Marese intended to take advantage of this fact. By means of certain Stock Exchange operations, with which he was perfectly familiar, having employed them previously on several occasions, he arranged that a very large amount of bullion should be transmitted to London from New York by the splendid steamer _Lucca_, due to start on December 3rd.
