"Hence, if the gun is properly trained and fired at precisely the right moment, and if the fuse does its work, the projectile will pass into the nucleus of the comet, and, before the heat has time to melt the shell, the charge will explode and the nucleus--the only dangerous part--will either be blown to fragments or dissipated in gas. Therefore, instead of what I might be allowed to call a premature Day of Judgment, we shall simply have a magnificent display of celestial fireworks, which will probably amount to nothing more than an unparalleled shower of shooting stars, as they are popularly called. "The details of the experiment will be practically the same as those Jules Verne described--I mean as regards the making and firing of the cannon--only, as we haven't time to get a big enough hole dug, I should strongly advise the acceptance of Lord Westerham's very opportune offer." "That's so," said Mr Parmenter, quietly, "but I've got a sort of fancy for running this business myself. My reflector discovered this comet, thanks, of course, to the good use you made of it, and it seems to me that I'm in a way responsible for making it harmless if that can be done, and so I'm not disposed to take that convenient colliery as a gift from anyone, no, not even you, Lord Westerham. You see, my lord, all that I can do here is just finding the dollars, and to a man in your position, doing his best to get as many men and horses and guns together for the defence of his country, money is money. Will you take a quarter of a million pounds for that colliery?" "No, I won't, Mr Parmenter," laughed Lord Westerham. "In the first place, the colliery isn't worth a tenth of that, and this country can very well afford to pay for her own defence. Besides, you must remember that you will have to pay for the work: I mean casing the pit-shaft, smelting the metal and building the shell, to say nothing of the thousand and one other expenses of which Lennard can tell you more than I. For one thing, I expect you will have a hundred thousand or so to pay in damage to surrounding property after that cannon has gone off. In other words, if you do save the world you'll probably have to pay pretty stiffly for doing it. They're excellent business people in Lancashire, you know." "I don't quite see the logic of that, Lord Westerham," replied Mr Parmenter a little testily. "If we can put this business through, the dollars couldn't be much better used, and if we can't they won't be much use to me or anyone else. It's worth doing, anyhow, if it's only to show what new-world enterprise helped with old-world brains can do in bringing off a really big thing, and that's why I want to buy that colliery."
