e New Year's activities that would soon take place when the
twenty-eighth day of Jupiter ended at midnight.

"Boston," said Carruthers. "Too near."

"Try Frisco," suggested Karl. "The tubes ought to be sufficiently
heated by this time."

The dial whirled beneath Carruthers slender fingers. The pictures
framed in the frosted panel faded. Another took its place. San
Francisco--an afternoon concert. Carruthers saw and listened for a
moment, then moved thousands of miles out to sea.

Shanghai drifted into the panel, announcing in sing-song accents the
weather reports. Following this came reports of various uprisings
along the Manchurian border.

While yet the three listeners and watchers bent their heads toward the
panel in the wall, a strange thing occurred. The silver frostiness of
the screen became violently agitated with what looked like tiny sparks
darting in and about each other like miniature solar systems.
Shanghai faded from the picture. All that remained visible now was the
jumbled mass of needle-pointed sparks of luminosity.

"Careful," warned Carruthers. "Slow up the speed of your reflector,

up the power of the dimensional tubes. Steady!"

From an invisible reproducer came a sharp, metallic crackling like
machine-gun bullets rattling on a tin roof. The sparks on the screen

"What do you read?" asked Carruthers.

"Point seven six nine," answered Karl.

"Shift it back towards the blue, about two points lower on the scale."

Danzig twisted two dials at the same time with minute exactness.
"Point seven six eleven," he intoned.

"Hold it," ordered Carruthers. "Blue should predominate." He turned
his eyes on the dancing sparks on the screen. They glowed now a deep
indigo blue. "Lock your dials against accidental turning. We're tuned
to the vanishing point."

Danzig rose to his feet. "What will we use?"

Carruthers looked hastily around the room. "Most anything will do."
His eyes rested on a glass test tube. Quickly he rose to his feet and
removed it from the wall rack. Then bending over the glass railing
that enclosed the mysterious square he placed it on the floor. He
turned now to the girl.

"Quiet, now,
