ach group will re-enter its particular aircar,
retaining control of the cube in each case, of course, and will at once
repair to his proper station. Telepathy is the mode of communication
with the cubes, and you rule them by your will. Each group, when
assembled by my father, will choose a leader before quitting this
laboratory, and such leader will remain in command of his group, under
the overlordship of the Spokesman to whom he reports with his group. You
understand!

"Your loyalty is unquestioned. You will consecrate your lives to the
welfare of the Gens to which you are going, since you no longer have a
Gens of your own!"

Sarka turned to the cubes, which had formed in a line just inside the
Exit Dome, and issued a mental command to the cube that had piloted his
aircar from the Moon. The cube faded out instantly, appearing
immediately afterward on the table of the vari-colored lights.

"Father," said Sarka, "while I am issuing orders to the Spokesmen,
please see if you can discover the secret of these cubes: how they are
actuated, the real extent of their intelligence! The rest of you, with
your cubes, depart immediately and report to your new Gens!"

Within ten minutes the divisions had been made, and the Radiant People
had entered the aircars and, outside the laboratory, risen free of the
Earth, and turned, each in its proper direction, for the Gens of its
assignment. The Sarkas and Jaska watched them go.

There remained but one aircar, standing outside on half a dozen of those
grim tentacles, with two tentacles swinging free, undulating to and fro
like serpents. Harnessed electricity actuating the tentacles--cars and
tentacles subservient to the cubes.

The aircars safely on their way, Sarka stepped to the Master Beryl,
tuned it down to normal speed, and signalled the Spokesmen of the Gens.

"The Moon and Mars are in alliance against us, and Dalis has allied
himself and his Gens with the ruler of the Moon! I don't know yet what
form the attack will take, but know this: that the safety of the world,
of all its people, rests in your hands, and that the war into which we
are going is potentially more vast than expected when this venture
began, and more devastating than the fight with the aircars of the Moon!
Coming to you, in aircars which we managed to take from the
Moon-people, are such of the people of the Gens of Dalis as were able to
return with me. Question t
