When Roy got out into the street again, after paying for the pie he had forgotten about, he was quite puzzled as to which direction to take to get back to his hotel. "Guess I'm off the trail," he told himself. "I'd ought to have brought a compass along. Let's see, which way is North?" He looked about for a sight of the sun, but, though it was shining, the tall buildings hid it from view. "Might as well be down in the grand canyon of the Colorado, as here in New York for all you can see of the sun," he murmured. "I ought to have taken more notice of the way I came, but what with going in so many buildings, and that express elevator, I'm all turned around." He tried to think which way to take, and then, getting over a little natural embarrassment about asking a stranger the road, he inquired of a well-dressed man the way to get to his hotel, the name of which, fortunately, Roy remembered. "Go right down those stairs," said the man, pointing to a flight which started in a little shelter built on the sidewalk. "Take an uptown express, and you'll land right at your hotel. There's a station there." "Station?" thought Roy. "That's a queer place for a station. Didn't have room for it above ground, I reckon." He walked down the flight of steps, finding himself in a brilliantly lighted place. Doing as he saw the crowd do he bought a ticket at a little window and then, seeing a sign "Uptown Express Trains," he followed the throng going in that direction. A moment later a string of cars came rumbling up along-side of the platform. "All aboard!" called the guard. The boy from the ranch got in and took a seat. The next moment the train started off at great speed, for it was an express, and made but few stops. Leaving the brilliantly-lighted station the cars plunged into darkness, relieved by an occasional electric lamp. "Must be a tunnel," thought Roy. "We'll come out on top of the ground in a minute, and I can see what New York looks like. Space is so crowded down town, I s'pose they have to tunnel for a few blocks." But the tunnel did not come to an end. In vain Roy waited for the train to emerge into daylight. Past station after station it rushed, the lights there showing for an instant, and then the darkness closing in again. Finally the express stopped. Several passengers got off, and more got on. Then it started up again, still whizzing through the dark. Roy could stand it no longer. Perhaps he had made a mistake and gotten into the wrong train This one might be destined for China, or some other under-ground port. Roy made his way to where a guard was standing. "Excuse me, stranger," he began, in his broad western tones. "But how long is this tunnel, anyhow?" "Tunnel? This ain't no tunnel!" "No? what is it then? It's a pretty good imitation. Looks like an underground river that has gone dry." "Why, this is the subway." "The subway?" "Sure. It goes right under the streets, all the way along New York."
