Herr Winckelkopf shrugged his shoulders, and left the room,
returning in a few minutes with a round cake of dynamite about the
size of a penny, and a pretty little French clock, surmounted by an
ormolu figure of Liberty trampling on the hydra of Despotism.

Lord Arthur's face brightened up when he saw it. 'That is just what
I want,' he cried, 'and now tell me how it goes off.'

'Ah! there is my secret,' answered Herr Winckelkopf, contemplating
his invention with a justifiable look of pride; 'let me know when
you wish it to explode, and I will set the machine to the moment.'

'Well, to-day is Tuesday, and if you could send it off at once--'

'That is impossible; I have a great deal of important work on hand
for some friends of mine in Moscow. Still, I might send it off to-
morrow.'

'Oh, it will be quite time enough!' said Lord Arthur politely, 'if
it is delivered to-morrow night or Thursday morning. For the moment
of the explosion, say Friday at noon exactly. The Dean is always at
home at that hour.'

'Friday, at noon,' repeated Herr Winckelkopf, and he made a note to
that effect in a large ledger that was lying on a bureau near the
fireplace.

'And now,' said Lord Arthur, rising from his seat, 'pray let me know
how much I am in your debt.'
