View of the clear-shining English scenery is often interrupted between London and Crew by long and short tunnels. The first one was disconcerting. Suddenly one knew that the train was shooting toward a black mouth in the hills. It swiftly yawned wider, and then in a moment the engine dived into a place inhabitated by every demon of wind and noise. The speed had not been checked, and the uproar was so great that in effect one was simply standing at the center of a vast, black-walled sphere. The tubular construction which one's reason proclaimed had no meaning at all. It was a black sphere, alive with shrieks. But then on the surface of it there was to be seen a little needle-point of light, and this widened to a detail of unreal landscape. It was the world; the train was going to escape from this cauldron, this abyss of howling darkness. If a man looks through the brilliant water of a tropical pool, he can sometimes see coloring the marvels at the bottom the blue that was on the sky and the green that was on the foliage of this detail. And the picture shimmered in the heat-rays of a new and remarkable sun. It was when the train bolted out into the open air that one knew that it was his own earth. Once train met train in a tunnel. Upon the painting in the perfectly circular frame formed by the mouth there appeared a black square with sparks bursting from it. This square expanded until it hid everything, and a moment later came the crash of the passing. It was enough to make a man lose his sense of balance. It was a momentary inferno when the fireman opened the furnace door and was bathed in blood-red light as he fed the fires. The effect of a tunnel varied when there was a curve in it. One was merely whirling then heels over head, apparently in the dark, echoing bowels of the earth. There was no needle-point of light to which one's eyes clung as to a star. From London to Crew, the stern arm of the semaphore never made the train pause even for an instant. There was always a clear track. It was great to see, far in the distance, a goods train whooping smokily for the north of England on one of the four tracks. The overtaking of such a train was a thing of magnificent nothing for the long-strided engine, and as the flying express passed its weaker brother, one heard one or two feeble and immature puffs from the other engine, saw the fireman wave his hand to his luckier fellow, saw a string of foolish, clanking flat-cars, their freights covered with tarpaulins, and then the train was lost to the rear.
