Then down upon the ledge, dropping into the Crimson Sea, sending up
geysers of ruby spray, dashing on the bridge, crushing the frog-men,
fell a shower of stone, mingled with distorted shapes and fragments
whose scales still flashed meteoric as they hurled from above.

"That which makes things fall upward," hissed Olaf. "That which I saw
in the garden of Lugur!"

The fiendish agency of destruction which Marakinoff had revealed to
Larry; the force that cut off gravitation and sent all things within
its range racing outward into space!

And now over the debris upon the ledge, striking with long sword and
daggers, here and there a captain flashing the green ray, moving on in
ordered squares, came the soldiers of the Shining One. Nearer and
nearer the verge of the ledge they pushed Nak's warriors. Leaping upon
the dwarfs, smiting them with spear and club, with teeth and spur, the
_Akka_ fought like devils. Quivering under the ray, they leaped and
dragged down and slew.

Now there was but one long line of the frog-men at the very edge of
the cliff.

And ever the clouds of dancing, diamonded atoms grew thicker over them
all!

That last thin line of the _Akka_ was going; yet they fought to the
last, and none toppled over the lip without at least one of the
armoured Murians in his arms.
