sodium peroxide, water condensers, and so forth. I remember the little heap they made in the corner—tins, and rolls, and boxes—convincingly matter-of-fact.
It was a strenuous time, with little chance of thinking. But one day, when we were drawing near the end, an odd mood came over me. I had been bricking up the furnace all the morning, and I sat down by these possessions dead beat. Everything seemed dull and incredible.
"But look here, Cavor," I said. "After all! What's it all for?"
He smiled. "The thing now is to go."
"The moon," I reflected. "But what do you expect? I thought the moon was a dead world."
He shrugged his shoulders.
"What do you expect?"
"We're going to see."
"Are we?" I said, and stared before me.
"You are tired," he remarked. "You'd better take a walk this afternoon."
"No," I said obstinately; "I'm going to finish this brickwork."
And I did, and insured myself a night of insomnia.
I don't think I have ever had such a night.
