ays heard that the capacity of even the human brain was almost
infinite. Isn't that true?" asked Margaret.

"Maybe it is, if the knowledge were built up gradually over generations.
I think maybe I can get most of this stuff into my peanut brain so I can
use it, but it's going to be an awful job."

"Is their brain really as far ahead of ours as I gathered from what I
saw of it?" asked Crane.

"It sure is," replied Seaton, "as far as knowledge and intelligence are
concerned, but they have nothing else in common with us. They don't
belong to the genus 'homo' at all, really. Instead of having a common
ancestor with the anthropoids, as they say we had, they evolved from a
genus which combined the worst traits of the cat tribe and the
carnivorous lizards--the most savage and bloodthirsty branches of the
animal kingdom--and instead of getting better as they went along, they
got worse, in that respect at least. But they sure do know something.
When you get a month or so to spare, you want to put on this harness and
grab his knowledge, being very careful to steer clear of his mental
traits and so on. Then, when we get back to the Earth, we'll simply tear
it apart and rebuild it. You'll know what I mean when you get this stuff
transplanted into your own skull. But to cut out the lecture, what's on
your mind, Dottie Dimple?"

"This planet Martin picked out is all wet, literally. The visibility is
fine--very few clouds--but this whole half of it is solid ocean. If
there are any islands, even, they're mighty small."

All four looked into the receiver. With the great magnification
employed, the planet almost filled the visiplate. There were a few
fleecy wisps of cloud, but the entire surface upon which they gazed was
one sheet of the now familiar deep and glorious blue peculiar to the
waters of that cuprous solar system, with no markings whatever.

"What d'you make of it, Mart? That's water all right--copper-sulphate
solution, just like the Osnomian and Urvanian oceans--and nothing else
visible. How big would an island have to be for us to see it from here?"

"So much depends upon the contour and nature of the island, that it is
hard to say. If it were low and heavily covered with their green-blue
vegetation, we might not be able to see even a rather large one, whereas
if it were hilly and bare, we could probably see one only a few miles in
diameter."

"Well, one good thing, anyway,
