“Well, how do you see what all it is to see?”

Mr. Head didn’t answer. Then as if the sight of people passing had given him the clue, he said,” You walk,” and started off down the street. Nelson followed, steadying his hat. So many sights and sounds were flooding in on him that for the first block he hardly knew what he was seeing. Mr. Head turned and looked behind him at the station they had left, a putty-colored terminal with a concrete dome on top. He thought that if he could keep the dome always in sight, he would be able to get back in the afternoon to catch the train again.

And, why not, another extract from the same story:

“The day is going to come,” Mr. Head prophesied, “when you’ll find you ain’t as smart as you think you are.” He had been thinking about this trip for several months but it was for the most part in moral terms that he conceived it. It was to be a lesson that the boy would never forget. He was to find out from it that he had no cause for pride merely because he had been born in a city. He was to find out that the city is not a great place. Mr. Head meant him to see everything there is to see in a city so that he would be content to stay at home for the rest of his life. He fell asleep thinking how the boy would at last find out that he was not as smart as he thought he was.
