on the subway

Conversation on the Subway is impossible. The ingenious gentleman who constructed it started with the object of making it noisy. Not ordinarily noisy, like a ton of coal falling on to a sheet of tin, but really noisy. So they fashioned the pillars of thin steel, and the sleepers of thin wood, and loosened all the nuts, and now a Subway train in motion suggests a prolonged dynamite explosion with the voice of some great cataract.
