ing intensity of such beams as those.

The skeletons tried to duplicate the ships' method of attack, but
failed. They were too slow. Not slow, exactly, either, but hesitant; as
though it required whole seconds for the commander--or operator? Or
remote controller?--of each skeleton to make it act. The ships were
winning.

"Hey!" Hilton yelped. "Oh--that's the one we saw back there. But what
in all space does it think it's doing?"

It was plunging at tremendous speed straight through the immense fleet
of embattled skeletons. It did not fire a beam nor energize a screen; it
merely plunged along as though on a plotted course until it collided
with one of the skeletons of the fleet and both structures plunged, a
tangled mass of wreckage, to the ground of the planet below.

Then hundreds of the ships shot forward, each to plunge into and explode
inside one of the skeletons. When visibility was restored another wave
of ships came forward to repeat the performance, but there was nothing
left to fight. Every surviving skeleton had blinked out of normal space.

The remaining ships made no effort to pursue the skeletons, nor did they
re-form as a fleet. Each ship went off by itself.

And on that distant planet of the Stretts the group of mechs watched
with amazed disbelief as light after light after light winked out on
their two-miles-long control board. Frantically they relayed orders to
the skeletons; orders which did not affect the losses.

"Brain-pans will blacken for this ..." a mental snarl began, to be
interrupted by a coldly imperious thought.

"That long-dead unit, so inexplicably reactivated, is approaching the
fuel world. It is ignoring the battle. It is heading through our fleet
toward the Oman half ... _handle_ it, ten-eighteen!"

"It does not respond, Your Loftiness."

"Then blast it, fool! Ah, it is inactivated. As encyclopedist, Nine,
explain the freakish behavior of that unit."

"Yes, Your Loftiness. Many cycles ago we sent a ship against the Omans
with a new device of destruction. The Omans must have intercepted it,
drained it of power and allowed it to drift on. After all these cycles
of time it must have come upon a small source of power and of course
continued its mission."

"That can be the truth. The Lords of the Universe must be informed."

"The mining units, the carriers and the refiners have not been affected,
Your Loftiness," a mech radiated.

"
