The Challenge from Beyond
Sheer fantasy, this. He stirred impatiently and flashed his light upon his watch. Close to
one o'clock; three hours more before the dawn. The beam fell and was focused upon the
warm crystal cube. He held it there closely, for minutes. He snapped It out, then watched.
There was no doubt about it now. As his eyes accustomed themselves to the darkness, he
saw that the strange crystal was glimmering with tiny fugitive lights deep within it like
threads of sapphire lightnings. They were at Its center and they seemed to him to come
from the pale disk with Its disturbing markings. And the disc itself was becoming larger
... the markings shifting shapes ... the cube was growing ... was it illusion brought about
by the tiny lightnings....
He heard a sound. It was the very ghost of a sound, like the ghosts of harp strings being
plucked with ghostly fingers. He bent closer. It came from the cube....
There was squeaking in the underbrush, a flurry of bodies and an agonized wailing like a
child in death throes and swiftly stilled. Some small tragedy of the wilderness, killer and
prey. He stepped over to where it had been enacted, but could see nothing. He again
snapped off the flash and looked toward his tent. Upon the ground was a pale blue
glimmering. It was the cube. He stooped to pick it up; then obeying some obscure
warning, drew back his hand.
And again, he saw, its glow was dying. The tiny sapphire lightnings flashing fitfully,
withdrawing to the disc from which they had come. There was no sound from it.
He sat, watching the luminescence glow and fade, glow and fade, but steadily becoming
dimmer. It came to him that two elements were necessary to produce the phenomenon.
The electric ray itself, and his own fixed attention. His mind must travel along the ray, fix
itself upon the cube's heart, if its beat were to wax, until ... what?
He felt a chill of spirit, as though from contact with some alien thing. It was alien, he
knew it; not of this earth. Not of earth's life. He conquered his shrinking, picked up the
cube and took It into the tent. It was neither warm nor cold; except for its weight he
would not have known he held it. He put it upon the table, keeping the torch turned from
it; then stepped to the flap of the tent and closed it.
He went back to the table, drew up the camp chair, and turned the flash directly upon the
cube, focusing it so far as he could upon its heart. He sent all his will, all his
concentration, along it; focusing will and sight upon the disc as he had the light.
As though at command, the sapphire lightnings burned forth. They burst from the disc
into the body of the crystal cube, then beat back, bathing the disc and the markings.
Again these began to change, shifting, moving, advancing, and retreating in the blue
gleaming. They were no longer cuneiform. They were things ... objects.
He heard the murmuring music, the plucked harp strings. Louder grew the sound and
louder, and now all the body of the cube vibrated to their rhythm. The crystal walls were
