d you select boys?"

"Because all the others were born in an atmosphere of superstition
and reared in it. It is in their blood and bones. We imagined
we had educated it out of them; they thought so, too; the Interdict
woke them up like a thunderclap! It revealed them to themselves,
and it revealed them to me, too. With boys it was different. Such
as have been under our training from seven to ten years have had
no acquaintance with the Church's terrors, and it was among these
that I found my fifty-two. As a next move, I paid a private visit
to that old cave of Merlin's--not the small one--the big one--"

"Yes, the one where we secretly established our first great electric
plant when I was projecting a miracle."

"Just so. And as that miracle hadn't become necessary then,
I thought it might be a good idea to utilize the plant now. I've
provisioned the cave for a siege--"

"A good idea, a first-rate idea."

"I think so. I placed four of my boys there as a guard--inside,
and out of sight. Nobody was to be hurt--while outside; but any
attempt to enter--well, we said just let anybody try it! Then
I went out into the hills and uncovered and cut the secret wires
which connected your bedroom with the wires that go to the dynamite
deposits under all our vast factories, mills, workshops, magazines,
etc., and about midnight I and my boys turned out and connected
that wire with the cave, and nobody but you and I suspects where
the other end of it goes to. We laid it under ground, of course, and
it was all finished in a couple of hours or so. We sha'n't have
to leave our fortress now when we want to blow up our civilization."

"It was the right move--and the natural one; military necessity,
in the changed condition of things. Well, what changes _have_ come!
We expected to be besieged in the palace some time or other, but
--however, go on."

"Next, we built a wire fence."

"Wire fence?"

"Yes. You dropped the hint of it yourself, two or three years ago."

"Oh, I remember--the time the Church tried her strength against
us the first time, and presently thought it wise to wait for a
hopefuler season. Well, how have you arranged the fence?"

"I start twelve immensely strong wires--naked, not insulated
--from a big dynamo in the cave--dynamo with no brushes except
a positive and a negative one--"

"Yes, that's right."

"The wires go out from the cave and fence in a circle of level
ground a hundred yards in
