versing the steam, backed the train for nearly a mile—retiring, like a jumper, in order to take a longer leap. Then, with another whistle, he began to move forward; the train increased its speed, and soon its rapidity became frightful; a prolonged screech issued from the locomotive; the piston worked up and down twenty strokes to the second. They perceived that the whole train, rushing on at the rate of a hundred miles an hour, hardly bore upon the rails at all.
And they passed over! It was like a flash. No one saw the bridge. The train leaped, so to speak, from one bank to the other, and the engineer could not stop it until it had gone five miles beyond the station. But scarcely had the train passed the river, when the bridge, completely ruined, fell with a crash into the rapids of Medicine Bow.
