"We sure did," answered Jack. "You weren't mistaken that time."

They got ready to move the projectile, but decided to remain over night
where they were. "Over night" being the way they spoke of it, though,
as I have said, there was perpetual daylight for fourteen days at a
time on the moon.

Professors Roumann and Henderson made a few more observations for
scientific purposes. They found traces of some vegetation, but it was
of little value for food, even to the lower forms of animal life, they
decided. There was also a little moisture; noticed at certain hours of
the day. But, in the main, the place where they had landed was most
desolate.

"I hope we get to a better place soon," said Jack, just before they
sealed themselves up in the projectile to travel to a new spot.

As distance was comparatively small on the moon, for her diameter is
only a little over two thousand miles and the circumference only about
six thousand six hundred miles, the _Annihilator_ could not be speeded
up. If it went too fast, it would soon be off the moon and into space
again.

Accordingly the Cardite motor was geared to send the big craft along at
about forty miles an hour, and at times they went even slower than
that, when they were passing over some part of the surface which the
professors wished to photograph or observe closely.

They did not rise high into the air, but flew along at an elevation of
about two hundred feet, steering in and out to avoid the towering peaks
