"Why not apply that idea of spring blinds--Cavorite blinds in strong
steel cases--to lifting weights?"

"It wouldn't work," he insisted. "After all, to go into outer space is not
so much worse, if at all, than a polar expedition. Men go on polar
expeditions."

"Not business men. And besides, they get paid for polar expeditions. And
if anything goes wrong there are relief parties. But this--it's just
firing ourselves off the world for nothing."

"Call it prospecting."

"You'll have to call it that.... One might make a book of it perhaps," I
said.

"I have no doubt there will be minerals," said Cavor.

"For example?"

"Oh! sulphur, ores, gold perhaps, possibly new elements."

"Cost of carriage," I said. "You know you're not a practical man. The
moon's a quarter of a million miles away."

"It seems to me it wouldn't cost much to cart any weight anywhere if you
packed it in a Cavorite case."

I had not thought of that. "Delivered free on head of purchaser, eh?"
