Read it through once

Next morning, we drove around town in the rain. The city seemed but little changed. It _was _greatly changed, but it did not seem so; because in St. Louis, as in London and Pittsburgh, you can't persuade a new thing to look new; the coal smoke turns it into an antiquity the moment you take your hand off it. The place had just about doubled its size, since I was a resident of it, and was now become a city of 400,000 inhabitants; still, in the solid business parts, it looked about as it had looked formerly. Yet I am sure there is not as much smoke in St. Louis now as there used to be. The smoke used to bank itself in a dense billowy black canopy over the town, and hide the sky from view. This shelter is very much thinner now; still, there is a sufficiency of smoke there, I think. I heard no complaint.
