We stopped again and I gave Peewee one-eighth of a charge. The tape was in very poor shape afterwards; I doubted if it would serve again. I said, “Peewee, why don’t you run your oxy-helium bottle dry while I carry this one? It’ll save your strength.”
“I’m all right.”
“Well, you won’t use air so fast with a lighter load.”
“You have to have your arms free. Suppose you slip?”
“Peewee, I won’t carry it in my arms, My righthand backpack bottle is empty; I’ll chuck it. Help me make the change and I’ll still be carrying only four-just balanced evenly.”
“Sure, I’ll help. But I’ll carry two bottles. Honest, Kip, the weight isn’t anything. But if I run the oxy-helium bottle dry, what would I breathe while you’re giving me my next charge?”
I didn’t want to tell her that I had doubts about another charge, even in those ever smaller amounts. “Okay, Peewee.”
She changed bottles for me; we threw the dead one down a black hole and went on. I don’t know how far we climbed nor how long; I know that it seemed like days-though it couldn’t have been, not on that much air. During mile after mile of trail we climbed at least eight thousand feet. Heights are hard to guess-but I’ve seen mountains I knew the heights of. Look it up yourself-the first range east of Tombaugh Station.
There’s a lot of climbing, even at one-sixth gee.
It seemed endless because I didn’t know how far it was nor how long it had been. We both had watches-under our suits. A helmet ought to have a built-in watch. I should have read Greenwich time from the face of Earth. But I had no experience and most of the time I couldn’t see Earth because we were deep in mountains-anyhow I didn’t know what time it had been when we left the ship.
Another thing space suits should have is rear-view mirrors. While you are at it, add a window at the chin so that you can see where you step. But of the two, I would take a rear-view mirror. You can’t glance behind you; you have to turn your entire body. Every few seconds I wanted to see if they were following us-and I couldn’t spare the effort. All that nightmare trek I kept imagining them on my heels, expecting a wormy hand on my shoulder. I listened for footsteps which couldn’t be heard in vacuum anyhow.
When you buy a space suit, make them equip it with a rear-view mirror. You won’t have Wormface on your trail but it’s upsetting to have even your best friend sneak up behind you. Yes, and if you are coming to the Moon, bring a sunshade. Oscar was doing his best and York had done an honest job on the air conditioning-but the untempered Sun is hotter than you would believe and I didn’t dare use air just for cooling, any more than Peewee could.
It got hot and stayed hot and sweat ran down and I itched all over and couldn’t scratch and sweat got into my eyes and burned. Peewee must have been parboiled. Even when the trail wound through deep gorges lighted only by reflection off the far wall, so dark that we turned on headlamps, I still was hot-and when we curved back into naked sunshine, it was almost unbearable. The temptation to kick the chin valve, let air pour in and cool me, was almost too much. The desire to be cool seemed more important than the need to breathe an hour hence.
If I had been alone, I might have done it and died. But Peewee was worse off than I was. If she could stand it, I had to.
I had wondered how we could be so lost so close to human habitation -and how crawly monsters could hide a base only forty miles from Tombaugh Station. Well, I had time to think and could figure it out because I could see the Moon around me.
Compared with the Moon the Arctic is swarming with people. The Moon’s area is about equal to Asia-with fewer people than Centerville. It might be a century before anyone explored that plain where Wormface was based. A rocket ship passing over wouldn’t notice anything even if camouflage hadn’t been used; a man in a space suit would never go there; a man in a crawler would find their base only by accident even if he took the pass we were in and ranged around that plain. The lunar mapping satellite could photograph it and rephotograph, then a technician in London might note a tiny difference on two films. Maybe. Years later somebody might check up-if there wasn’t something more urgent to do in a pioneer outpost where everything is new and urgent.
