light! He looked through into another universe, a universe lying
infinitely far across alien dimensions from our own, yet one that could
be reached through this door between dimensions. It was a green
universe, flooded with an awful green light that was somehow more akin
to darkness than to light, a throbbing, baleful luminescence.

Ennis saw dimly through green-lit spaces a city in the near distance, an
unholy city of emerald hue whose unsymmetrical, twisted towers and
minarets aspired into heavens of hellish viridity. The towers of that
city swayed to and fro and writhed in the air. And Ennis saw that here
and there in the soft green substance of that restless city were circles
of lurid light that were like yellow eyes.

In ghastly, soul-shaking apprehension of the utterly alien, Ennis knew
that the yellow circles were _eyes_--that that hell-spawned city of
another universe was _living_--that its unfamiliar life was single yet
multiple, that its lurid eyes looked now through the Door!

Out from the insane living metropolis glided pseudopods of its green
substance, glided toward the Door. Ennis saw that in the end of each
pseudopod was one of the lurid eyes. He saw those eyed pseudopods come
questing through the Door, onto the dais.

The yellow eyes of light seemed fixed on the row of stiff victims, and
the pseudopods glided toward them. Through the open door was beating
wave on wave of unfamiliar, tingling forces that Ennis felt even through
the protective robe.

The hooded multitude bent in awe as the green pseudopods glided toward
the victims faster, with avid eagerness. Ennis saw them reaching for the
prisoners, for Ruth, and he made a tremendous mental effort to break the
spell that froze him. In that moment pistol-shots crashed across the
cavern and a stream of bullets smashed the pulsing web of wires!

The Door began instantly to close. Darkness crept back around the edges
of the mighty oval. As though alarmed, the lurid-eyed pseudopods of that
hell-city recoiled from the victims, back through the dwindling Door.
And as the Door dwindled, the light in the cavern was failing.

"Ruth!" yelled Ennis madly, and sprang forward and grasped her, his
pistol leaping into his other hand.

"Ennis--quick!" shouted Campbell's voice across the cavern.

The Door dwindled away altogether; the great oval facet was completely
black. The light was fast dying too.

The chief priest sprang madly toward Ennis, and as he di
