LOMAX. Oh come! I'm not a fool. I took jolly good care to blow it out before I chucked it away.

BILTON. The top of it was red hot inside, sir.

LOMAX. Well, suppose it was! I didn't chuck it into any of your messes.

UNDERSHAFT. Think no more of it, Mr Lomax. By the way, would you mind lending me your matches?

LOMAX [offering his box] Certainly.

UNDERSHAFT. Thanks. [He pockets the matches].

LOMAX [lecturing to the company generally] You know, these high explosives don't go off like gunpowder, except when they're in a gun. When they're spread loose, you can put a match to them without the least risk: they just burn quietly like a bit of paper. [Warming to the scientific interest of the subject] Did you know that Undershaft? Have you ever tried?

UNDERSHAFT. Not on a large scale, Mr Lomax. Bilton will give you a sample of gun cotton when you are leaving if you ask him. You can experiment with it at home. [Bilton looks puzzled].

SARAH. Bilton will do nothing of the sort, papa. I suppose it's your business to blow up the Russians and Japs; but you might really stop short of blowing up poor Cholly. [Bilton gives it up and retires into the shed].

LOMAX. My ownest, there is no danger. [He sits beside her on the shell].
