'Dear me,' said Mellish. 'Now I never knew that before, Blaize. Remarkable. But this ought to be seen to. In the meantime, I had better ask the Headmaster to give out that the Museum is closed until further notice, I think.'

And closed the Museum has been ever since. That further notice has never been given. And yet nobody seems to feel as if an essential part of their life had ceased to be, so to speak. Curious. Bradshaw, after a short explanation, was allowed to go away without a stain—that is to say, without any additional stain—on his character. We left the authorities discussing the matter, and went downstairs.

'Sixpence isn't enough,' I said, 'take this penny. It's all I've got. You shall have the sixpence on Saturday.'

'Thanks,' said Bradshaw.' Was the Thucydides paper pretty warm?'

'Warmish. But, I say, didn't you get a beastly shock when you locked the door?'
