“Very good. You are also aware, I presume, that modern projectiles are either made of or tipped with steel. It may possibly have come to your ears that magnets attract steel. Permit me now to show you a small experiment.” He bent over his apparatus, and I suddenly heard the snapping of electricity. “This,” he continued going across to the packing case, “is a saloon pistol, and will be exhibited in the museums of the next century as being the weapon with which the new era was inaugurated. Into the breech I place a Boxer cartridge, specialty provided for experimental purposes with a steel bullet. I aim point blank at the dab of red sealing wax upon the wall, which is four inches above the magnet. I am an absolutely dead shot. I fire. You will now advance, and satisfy yourself that the bullet is flattened upon the end of the magnet, after which you will apologise to me for that grin.” I looked, and it certainly was as he had said. “I’ll tell you what I would do,” he cried. “I am prepared to put that magnet in Hetty’s bonnet, and to let you fire six shots straight at her face. How’s that for a test? You wouldn’t mind, Hetty? Eh, what!” “I don’t think she would have objected, but I hastened to disclaim any share in such an experiment. “Of course, you see that the whole thing is to scale. My warship of the future carries at her prow and stern a magnet which shall be as much larger than that as the big shell will be larger than this tiny bullet. Or I might have a separate raft, possibly, to carry my apparatus. My ship goes into action. What happens then, Munro? Eh, what! Every shot fired at her goes smack on to the magnet. There’s a reservoir below into which they drop when the electric circuit is broken. After every action they are sold by auction for old metal, and the result divided as prize money among the crew. But think of it, man! I tell you it is an absolute impossibility for a shot to strike any ship which is provided with my apparatus. And then look at the cheapness. You don’t want armour. You want nothing. Any ship that floats becomes invulnerable with one of these. The war ship of the future will cost anything from seven pound ten. You’re grinning again; but if you give me a magnet and a Brixton trawler with a seven-pounder gun I’ll show sport to the finest battle-ship afloat.” “Well, there must be some flaw about this,” I suggested. “If your magnet is so strong as all that, you would have your own broadside boomeranging back upon you.” “Not a bit of it! There’s a big difference between a shot flying away from you with all its muzzle velocity, and another one which is coming towards you and only needs a slight deflection to strike the magnet. Besides, by breaking the circuit I can take off the influence when I am firing my own broadside. Then I connect, and instantly become invulnerable.” “And your nails and screws?” “The warship of the future will be bolted together by wood.”
