In the center of
the picture on the screen were those half-dozen amphibians laying waste
Manhattan. Maniel set his intricate, delicate machinery into motion.

Instantly the amphibians there seemed to become misty, shadowy, and to
lift out of Manhattan up above the roof-tops of skyscrapers still
remaining, nebulous and wraithlike as ghost-shrouds--yet swinging
outward from the earth with speed almost too swift for the eye to
detect.

But where the amphibians had rested there stood, reclined--in all sorts
of postures, surprising and even a bit ridiculous--the men of Moyen who
had operated the monsters of Moyen!

From the Central Radio tower went forth a mighty voice of command to the
planes which had been engaging the aero-subs off the coast.

"Slay! Slay!"

Down flashed the planes of the Americas, and their guns were blazing,
inaudibly, but none the less deadly of aim and of purpose, straight into
the midst of the men of Moyen who had thus been left marooned and almost
helpless with the vanishing of their amphibians.

And, noting how they fell in strangled, huddled heaps before the
vengeful fire of the American planes, the Secret Agents sighed, and
Maniel, his face alight with the pride of accomplishment, switched to
another point along the coast.

And as a new group of the monsters of Moyen came into view, and Maniel
bent to his labors afresh, the hated voice of the master mobster broke
once more in the Secret Room.

"Enough, Kleig! Enough! We will surrender to save lives! I stipulate
only that my own life be spared!"

To which Prester Kleig made instant reply.

"Did you offer us choice of surrender? Did you spare the lives of our
people which, with your control of your golden rays, you could easily
have done? No! Nor will we spare lives, least of all the life of Moyen!"

The whirring again, as of the whirring of doves' wings. More metal
monsters, even as golden tongues spewed forth from their many sides,
vanished from view, leaping skyward, while the operators of them were
left to the mercies of the remaining airmen of the Americans.

* * * * *

Voicelessly the word went forth:

"Slay! Slay!"

It was Charmion who begged for mercy for the vanquished as, one by one,
as surely as fate, the monsters with their contained aero-subs were
blotted out, leaving pilots and operators behind them. Down upon these
dropped the airmen of the
