He scowled. "Damn wall." Then he shrugged. I thought that was all he was going to say. Then he went on.

"These people, we look out for 'em, you hear? Maybe we don't go for what they're doin'. But they got it rough, you know?" He looked at me, expecting something. I never did get the knack of talking to these laconic Westerners. I always felt that I was making my sentences too long. They use a shorthand of grunts and shrugs and omitted parts of speech, and I always felt like a dude when I talked to them.

"Do they welcome guests?" I asked. "I thought I might see if I could spend the night."

He shrugged again, and it was a whole different gesture.

"Maybe. They all deaf and blind, you know?" And that was all the conversation he could take for the day. He made a clucking sound and galloped away.

I continued down the wall until I came to a dirt road that wound up the arroyo and entered the wall. There was a wooden gate, but it stood open. I wondered why they took all the trouble with the wall only to leave the gate like that. Then I noticed a circle of narrow-gauge train tracks that came out of the gate, looped around outside it, and rejoined itself. There was a small siding that ran along the outer wall for a few yards.

I stood there a few moments. I don't know what entered into my decision. I think I was a little tired of sleeping out, and I was hungry for a home-cooked meal. The sun was getting closer to the horizon. The land to the west looked like more of the same. If the highway had been visible, I might have headed that way and hitched a ride. But I turned the other way and went through the gate.

I walked down the middle of the tracks. There was a wooden fence on each side of the road, built of horizontal planks, like a corral. Sheep grazed on one side of me. There was a Shetland sheepdog with them, and she raised her ears and followed me with her eyes as I passed, but did not come when I whistled.
