The jumping around in the snow made him sweat, and this sweat gathered between his skins.
This was a literal fact, not a fantasy, for he did have two skins. One of them was his own deeply bronzed
hide, and the other one, the outer one covering his body, was made of a transparent plastic in which he
had dunked himself from head to toes. The plastic was a special one, and only he himself knew how he
had concocted it. There was nothing else like it on earth. And yet he was not satisfied.
He was, in fact, far from satisfied, because after he had bounced around in the cold, then stood
motionless until the stuff cooled off, then bounced around some more, the plastic began to crack. It
would not stand the combination of cold, perspiration and flexing. Something was wrong.
He stood there in his disgust, the cold through the cracks that had opened in the plastic cutting at him like
knives. It was not perfect, and he was disappointed. Everything had been going so well.
America had raw material to make the plastic in large quantities; it was harmless to the skin; it could be
applied to the body with a brush, or a man could merely jump into a vat of it, and it would coat his body
and harden at once; it could be removed almost instantaneously and harmlessly with another chemical
application. All of this he had worked out. But now it was cracking.
The acids or salines in body perspiration might have something to do with the failure, he reflected.
The plastic had one other quality: it was almost a complete insulator against heat or cold. Soldiers in
tanks and pilots in fighting planes need have no fear of fire if he could perfect the stuff. The plastic would
not wear well and he knew it could never be made to wear well enough to make suits of it, hence the
idea of coating the skin with it. These coatings could be renewed either on garments or on the skin. The
United States fighting forces needed such a thing.
He turned and walked back to his Fortress of Solitude, intent on continuing the experiments.
HE had lately changed the outside appearance of his Fortress of Solitude, somewhat. The place, in the
beginning, had been a dome affair, like an igloo, but of enormous size. Now, since the change, it was
more rugged and completely resembled a chunk of ice protruding from the arctic ice pack, there not even
being a sign that it actually stood on an island. The change was one he had considered necessary because
of the increased number of planes flying over what had hitherto been unexplored waste.
The Fortress of Solitude was a secret from the world.
Not, in the strict sense, from the world. There were the Eskimos whom he had trained, and who had
done the original construction and recently the remodeling. They lived here and took care of the place
during his long periods of absence. He had trained the Eskimos and knew he could completely trust
them, which was something he could say of only five other men and one woman in the civilized world.
The Eskimos were gone now. They never remained here while he was working. They took their hunting
trips then.
He entered the Fortress. There were three doors for strength and insulation against the terrific outer cold.
Inside, one could look up and see the stars at many points, because the dome was of a plastic material so
polarized that it would pass light in only one direction, a substance that was not a secret.
(The peculiar association of light and plastic materials has probably been called to the attention of almost
everyone. There is, for instance, the plastic material of transparent type through rods of which light can be
piped, around corners, much as water is conducted through a pipe.)
