Heinlein, Robert A – Have Space Suit will Travel

“But what should we do?”

“I think we ought to keep going until you are absolutely certain the pass can’t be any farther. You watch for the pass and I’ll watch for crawler tracks. Then, when you’re certain that we’ve come too far, we’ll turn back. We can’t afford to make short casts like a dog trying to pick up a rabbit’s scent.”

“All right.”

I had counted two thousand more paces, another mile, when Peewee stopped. “Kip? It can’t be ahead of us. The mountains are higher and solider than ever.”

“You’re sure? Think hard. Better to go another five miles than to stop too short.”

She hesitated. She had her face pushed up close to her lens while we touched helmets and I could see her frown. Finally she said, “It’s not up ahead. Kip.”

“That settles it. To the rear, march! ‘Lay on, Macduff, and curs’d be him who first cries, “Hold, enough!” ‘ ”

“King Lear.”

“Macbeth. Want to bet?”

Those tracks were only half a mile behind us-I had missed them. They were on bare rock with only the lightest covering of dust; the Sun had been over my shoulder when we first crossed them, and the caterpillar tread marks hardly showed-I almost missed them going back. They led off the plain and straight up into the mountains.

We couldn’t possibly have crossed those mountains without following the crawler’s trail; Peewee had had the optimism of a child. It wasn’t a road; it was just something a crawler on caterpillar treads could travel. We saw places that even a crawler hadn’t been able to go until whoever pioneered it set a whopping big blast, backed off and waited for a chunk of mountain to get out of the way. I doubt if Skinny and Fatty carved that goat’s path; they didn’t look fond of hard work. Probably one of the exploration parties. If Peewee and I had attempted to break a new trail, we’d be there yet, relics for tourists of future generations.

But where a tread vehicle can go, a man can climb. It was no picnic; it was trudge, trudge, trudge, up and up and up-watch for loose rock and mind where you put your feet. Sometimes we belayed with the line. Nevertheless it was mostly just tedious.

When Peewee had used that half-charge of oxygen, we stopped and I equalized pressure again, this time being able to give her only a quarter charge-like Achilles and the tortoise. I could go on indefinitely giving her half of what was left-if the tape held out. It was in bad shape but the pressure was only half as great and I managed to keep the hoses together until we closed valves.

I should say that I had it fairly easy. I had water, food, pills, dexedrine. The last was enormous help; any time I felt fagged I borrowed energy with a pep-pill. Poor Peewee had nothing but air and courage.

She didn’t even have the cooling I had. Since she was on a richer mix, one bottle being pure oxygen, it did not take as much flow to keep up her blood-color index-and I warned her not to use a bit more than necessary; she could not afford air for cooling, she had to save it to breathe.

“I know, Kip,” she answered pettishly. “I’ve got the needle jiggling the red light right now. Think I’m a fool?”

“I just want to keep you alive.”

“All right, but quit treating me as a child. You put one foot in front of the other. I’ll make it.”

“Sure you will!”

As for the Mother Thing she always said she was all right and she was breathing the air I had (a trifle used), but I didn’t know what was hard-ship to her. Hanging by his heels all day would kill a man; to a bat it is a nice rest-yet bats are our cousins.

I talked with her as we climbed. It didn’t matter what; her songs had the effect on me that it has to have your own gang cheering. Poor Peewee didn’t even have that comfort, except when we stopped and touched helmets-we still weren’t using radio; even in the mountains we were fearful of attracting attention.
