"But I thought it was peace that those from the stars desired," said the
old electrician. "Through my radiovisor I heard--"

"That was sent out," explained Steinholt, "to relieve the fears of the
people and to keep them in order."

Swiftly the distorted figure of the old man sped to a great switchboard,
where he pressed button after button.

The very ground commenced to vibrate around them and the massive
structure seemed to be alive with straining power.

Then Steinholt, going to a corner of the intricate board, adjusted a few
levers, while his gnomelike companion watched him carefully.

"And now, Gaeble," the scientist said impressively, "these are your
orders. At precisely the hour of four o'clock in the morning make one
connection with this switch."

He indicated, with a stubby finger, the lever to be operated.

"Keep the circuit closed for just four seconds," he added slowly, "and
then break it. Do you understand, Gaeble?" he demanded.

"I do," replied the old man.

"Then," continued Steinholt, "after you break that connection you
quickly will close this next circuit. Keep it closed for four seconds

"I will do that immediately," Gaeble replied.

Dirk and Steinholt shot up to the roof again and the building over which
they walked seemed to be quivering with life.

They could see that all of the mammoth dynamos beneath them were
revolving and the humming which they had heard before had changed into
an ugly, vibrant roar.

Again they took flight and, reaching Manhattan, they continued north and
east to the shore of Long Island Sound.

Long before the old East River had been filled in and the space which it
had occupied reclaimed for building purposes. All indications of its
former bed had been obliterated by mammoth terraced structures.

When they reached their destination on the shore of the Sound a small
submarine, which Dirk had ordered by radio, was awaiting them.

"Submerge and
