Perhaps it is the youthful romanticism of America which makes our subways so much more exciting than those of Europe. The Englishman is too cautious and too conservative to trust himself away from the earth's surface more than two minutes at a time. So the trains that run through the London tube are tame, cowardly things. They timidly run underground for half a mile or so and pop their heads out into the air and sunlight or fog at every station. But the New York subway train is ready to take a chance. It dives into the earth and "stays under," like a brave diver, for an hour at a time. And when it does emerge, what splendor attends its coming! There is a glimmer of sunshine at the One Hundred and Sixteenth Street Station; the blue and white of the walls and pillars reflect a light not wholly artificial. Then there is a brief stretch of fantastically broken darkness. Passengers in the first car can see ahead of them, at Manhattan Street, a great door of sunshine. At last there is a strange change in the rumble of the wheels, for the echoing roof and walls are gone, and the train leaves its tunnel not to run humbly over the ground, but to rise higher and higher until it comes to a sudden halt above the chimneys and tree tops. To say that the grub becomes a butterfly does not fit the case, for the grub is a slow-moving beast and a butterfly's course is capricious. Rather, it is as if, by some tremendous magic, a great snake became a soaring eagle. And how keenly all the passengers enjoy their few seconds in the open air! When they hurried down the steps to the train, they were scornful of the atmosphere they were leaving, they had no thought of tasting wind and watching sunlight. Now they are become, for the moment, connoisseurs of these delectable things; they wish the train would linger at Manhattan Street, not inevitably plunge at once into its roaring cavern. But the train is wise, it knows brevity is essential to all exquisite things, so it gives its passengers only an evanescent glimpse of the glories they have just now learned to appreciate. This is a part of the great conspiracy of the subway. It is regarded only as a swift and convenient and uncomfortable carrier, and it has no wish to be otherwise interpreted. But those who have studied it know the hidden purposes it constantly and effectively serves. It is showing our generation the value of mankind's commonest and most precious gifts, by taking them away.
