'Because all these places,' said the Owl, 'are in danger of being blown up. If you could get a Home Ruler to take you round now; but I'm afraid it wouldn't do, as he might put you into an explosion and leave you there, as likely as not. Besides, I was forgetting, you are immortal, aren't you? You couldn't be blown up? If so, it is all right.'

'I don't suppose I could,' said Queen Mab a little doubtfully, 'but still I shouldn't care to try. What is it like?'

'I don't know,' replied her mentor. 'I have never tried it myself. You had better ask Mr. Bradlaugh, or some eminent popular sciolist Huxley or Spencer would do. They have been exploding or blowing up popular theology for a number of years, and popular theology and Mr. Joseph Cook have been exploding them. As far as I can make out, they both appear to think it very good fun. But I was going to tell you about the black bags, which are filled with dynamite, a very explosive though inexpensive substance indeed, and carried by persons called "dynamiters." These bags are left at large in public buildings, while the dynamitards go away, and as soon as their owners turn the corner the bags explode and blow up the buildings, and anyone who happens to be about.'

'Why do they do it?' exclaimed Queen Mab, breathless.

'Nobody seems to know,' said the Owl. 'It is one of the problems of the nineteenth century. Even the dynamiters themselves don't appear to have gone into the whole logic of it I suppose that they are tired of only blowing things up on paper, and they are people who have a great objection to things in general. They complain that they can't get justice from the universe in its present state of preservation, and therefore they are going to blow as much of it as possible into what they call smithereens, and try to get justice from the smithereens. It is a new scheme they have hit upon, a kind of scientific experiment. The theory appears to be, that justice is the product of Nihilism plus public buildings blown up by dynamite, and that the more public buildings they blow up the more justice they will obtain. I hear that they have also started a company for supplying statesmen, and all public orators except Home Rulers, with nitro-glycerine jujubes to improve the voice. Nitro-glycerine is a kind of condensed dynamite. A City sparrow told me—but perhaps it was only his fun—that they were borrowing the money from the Government, under the pretext of applying it to a fund for presenting three-and-sixpenny copies of Jevons' "Logic" to Members of Parliament who can't afford to buy the book for themselves. It is reported, also, that if the Nihilists can't obtain justice enough by any less extensive measures, they will lower a great many kegs of nitro-glycerine to the molten nucleus of the globe, and then—'

'Then?' said Queen Mab, much excited.

'Then the globe will explode, and all the inhabitants, even the dynamiters themselves; but justice will remain; according to the theory, that is. But it is rather an expensive experiment.'

'How dreadful!' said the fairy. 'Do you think I had better not go to London?'

'I think you might,' replied the Owl thoughtfully. 'There would be a little risk certainly; but you could fly high, and remember that dynamite strikes downwards. You had better take the sparrow, though, for I'm afraid I should attract too much attention. Otherwise I should like to go with you.'

'I will make us both invisible,' said Queen Mab. 'That will be easy.'
