ourse, uranium is a much more efficient source of power," agreed
Rovol, "and you are to be congratulated for thinking of it. It perhaps
would not have occurred to one of us, since the heavy metals of that
highly efficient group are very rare here. Building a new exciter for
uranium is a simple task, and the converters for the corona-loss will,
of course, require no change, since their action depends only upon the
frequency of the emitted losses, not upon their magnitude."

"Hadn't you suspected that some of the Fenachrone might be going to lead
us a life-long chase?" asked Dunark curiously.

"We have not given the matter a thought, my son," the Chief of the Five
made answer. "As your years increase, you will learn not to anticipate
trouble and worry. Had we thought and worried over the matter before the
time had arrived, you will note that it would have been pain wasted, for
our young friend Seaton has avoided that difficulty in a truly scholarly
fashion."

"All set, then, Rovol?" asked Seaton, when the forces flying from the
projector had built the compound exciter which would make possible the
disruption of the atoms of uranium. "The metal, enough of it to fill all
the spare space in the hull, will be here tomorrow. You might give Crane
and me the method of operating this projector, which I see is vastly
more complex even than the one in the Area of Experiment."

"It is the most complete thing ever seen upon Norlamin," replied Rovol
with a smile. "Each of us installed everything in it that he could
conceive of ever being of the slightest use, and since our combined
knowledge covers a large field, the projector is accordingly quite
comprehensive."

Multiple headsets were donned, and from each of the Norlaminian brains
there poured into the minds of the two Terrestrials a complete and
minute knowledge of every possible application of the stupendous
force-control banked in all its massed intricacy before them.

"Well, that's some outfit!" exulted Seaton in pleased astonishment as
the instructions were concluded. "It can do anything but lay an egg--and
I'm not a darn bit sure that we couldn't make it do that! Well, let's
call the girls and show them around this thing that's going to be their
home for quite a while."

While they were waiting, Dunark led Seaton aside.

"Dick, will you need me on this trip?" he asked. "Of course I knew there
was something on your mind when you didn't send me home when you let
Urvan,
