“The camera might have moved.”

“The crag here is sharp enough. And the men swear it was running. Imagine the metabolism it must have to run at that oxygen pressure. Look, boss, would you have believed in deep-sea fish if you'd never heard of them? You have fish which are looking for new niches in environment which they can exploit, so they go deeper and deeper into the abyss until one day they find they can't return.

They've adapted so thoroughly they can live only under tons of pressure.”

“Well-”

“Damn it, can't you reverse the picture? Creatures can be forced up a mountain, can't they? They can learn to stick it out in thinner air and colder temperatures. They can live on moss or on occasional birds, just as the deep-sea fish in the last analysis live on the upper fauna that slowly go filtering down. Then, someday, they find they can't go down again. I don't even say they're men. They can be chamois or mountain goats or badgers or anything.”

I said stubbornly, “The witnesses said they were vaguely manlike, and the reported footprints are certainly manlike.”

“Or bearlike,” said Jimmy. “You can't tell.”

So that's when I said, “It's about time we did something about it.”

Jimmy shrugged and said, “They've been trying to climb Mount Everest for forty years.” And he shook his head.

“For gossake,” I said. “ All you mountain climbers are nuts. That's for sure. You're not interested in getting to the top. You're just interested in getting to the top in a certain way. It's about time we stopped fooling around with picks, ropes, camps, and all the paraphernalia of the Gentlemen's Club that sends suckers up the slopes every five years or so.”

“What are you getting at?”

“They invented the airplane in 1903, you know?”

“You mean fly over Mount Everest!” He said it the way an English lord would say, “Shoot a fox!” or an angler would say, “Use worms!”
