Perhaps she was dreaming of Earth again.
Suddenly, watching her, I didn't care if they laughed at me or lectured me on my responsibilities to the government as if I were a senile fool. I was going to the spaceport. I was going to find out if, somehow, we couldn't go back.
I got up and dressed and went out, walking softly so as not to awaken her. But even so she heard me and called out to me.
"Lewis...."
I turned at the head of the stairs and looked back into the room.
"Don't get up, Martha," I said. "I'm going into town."
"All right, Lewis."
She relaxed, and a minute later she was asleep again. I tiptoed downstairs and out the front door to where the trike car was parked, and started for the village a mile to the west.
It was desert all the way. Dry, fine red sand that swirled upward in choking clouds, if you stepped off the pavement into it. The narrow road cut straight through it, linking the outlying district farms to the town. The farms themselves were planted in the desert. Small, glassed-in houses and barns, and large greenhouses roofed with even more glass, that sheltered the Earth plants and gave them Earth air to breathe.
