The cab finally rolled out of the gas-lit vault into a vast expanse of gloom. This changed to the shadowy lines of a street that was like a passage in a monstrous cave. The lamps winking here and there resembled the little gleams at the caps of the miners. They were not very competent illuminations at best, merely being little pale flares of gas that at their most heroic periods could only display one fact concerning this tunnel--the fact of general direction. But at any rate I should have liked to have observed the dejection of a search-light if it had been called upon to attempt to bore through this atmosphere. In it each man sat in his own little cylinder of vision, so to speak. It was not so small as a sentry-box nor so large as a circus tent, but the walls were opaque, and what was passing beyond the dimensions of his cylinder no man knew. It was evident that the paving was very greasy, but all the cabs that passed through my cylinder were going at a round trot, while the wheels, shod in rubber, whirred merely like bicycles. The hoofs of the animals themselves did not make that wild clatter which I knew so well. New York in fact, roars always like ten thousand devils. We have ingenuous and simple ways of making a din in New York that cause the stranger to conclude that each citizen is obliged by statute to provide himself with a pair of cymbals and a drum. If anything by chance can be turned into a noise it is promptly turned. We are engaged in the development of a human creature with very large, sturdy, and doubly, fortified ears. It was not too late at night, but this London moved with the decorum and caution of an undertaker. There was a silence, and yet there was no silence. There was a low drone, perhaps a humming contributed inevitably by closely-gathered thousands, and yet on second thoughts it was to me silence. I had perched my ears for the note of London, the sound made simply by the existence of five million people in one place. I had imagined something deep, vastly deep, a bass from a mythical organ, but found as far as I was concerned, only a silence. New York in numbers is a mighty city, and all day and all night it cries its loud, fierce, aspiring cry, a noise of men beating upon barrels, a noise of men beating upon tin, a terrific racket that assails the abject skies. No one of us seemed to question this row as a certain consequence of three or four million people living together and scuffling for coin, with more agility, perhaps, but otherwise in the usual way. However, after this easy silence of London, which in numbers is a mightier city, I began to feel that there was a seduction in this idea of necessity. Our noise in New York was not a consequence of our rapidity at all. It was a consequence of our bad pavements.
