t about the end of that time I would take a moment's
leisure and blow up Merlin's stone tower by fires from heaven;
in the meantime, whoso listened to evil reports about me, let him
beware. Furthermore, I would perform but this one miracle at
this time, and no more; if it failed to satisfy and any murmured,
I would turn the murmurers into horses, and make them useful.
Quiet ensued.

I took Clarence into my confidence, to a certain degree, and we
went to work privately. I told him that this was a sort of miracle
that required a trifle of preparation, and that it would be sudden
death to ever talk about these preparations to anybody. That made
his mouth safe enough. Clandestinely we made a few bushels of
first-rate blasting powder, and I superintended my armorers while
they constructed a lightning-rod and some wires. This old stone
tower was very massive--and rather ruinous, too, for it was Roman,
and four hundred years old. Yes, and handsome, after a rude
fashion, and clothed with ivy from base to summit, as with a shirt
of scale mail. It stood on a lonely eminence, in good view from
the castle, and about half a mile away.

Working by night, we stowed the powder in the tower--dug stones
out, on the inside, and buried the powder in the walls themselves,
which were fifteen feet thick at the base. We put in a peck
at a time, in a dozen places. We could have blown up the Tower
of London with these charges. When the thirteenth night was come
we put up our lightning-rod, bedded it in one of the batches of
powder, and ran wires from it to the other batches. Everybody
had shunned that locality from the day of my proclamation, but
on the morning of the fourteenth I thought best to warn the people,
through the heralds, to keep clear away--a quarter of a mile away.
Then added, by command, that at some time during the twenty-four
hours I would consummate the miracle, but would first give a brief
notice; by flags on the castle towers if in the daytime, by
torch-baskets in the same places if at night.

Thunder-showers had been tolerably frequent of late, and I was
not much afraid of a failure; still, I shouldn't have cared for
a delay of a day or two; I should have explained that I was busy
with affairs of state yet, and the people must wait.

Of course, we had a blazing sunny day--almost the first one without
a cloud for three weeks; things always happen so. I kept secluded,
and watched the weather. Clarence droppe
