to the force of gravity. Looking back, he could see by the faint light
from new snow that the driving-wheels on the rear engine were bigger than
his own, and that a tall figure stood atop of the cars and gestured
franticly. At a sharp turn in the track he found the other train but two
hundred yards behind, and as he swept around the curve the engineer who
was chasing him leaned from his window and laughed. His face was like
dough. Snow was falling and had begun to drift in the hollows, but the
trains flew on; bridges shook as they thundered across them; wind
screamed in the ears of the passengers; the suspected bridge was reached;
Edwards's heart was in his throat, but he seemed to clear the chasm by a
bound. Now the switch was in sight, but No. 19 was not there, and as the
brakes were freed the train shot by like a flash. Suddenly a red light
appeared ahead, swinging to and fro on the track. As well be run into
behind as to crash into an obstacle ahead. He heard the whistle of the
pursuing locomotive yelp behind him, yet he reversed the lever and put on
brakes, and for a few seconds lived in a hell of dread.

Hearing no sound, now, he glanced back and saw the wild train almost leap
upon his own--yet just before it touched it the track seemed to spread,
the engine toppled from the bank, the whole train rolled into the canon
and vanished. Edwards shuddered and listened. No cry of hurt men or hiss
of steam came up--nothing but the groan of the wind as it rolled through
the black depth. The lantern ahead, too, had disappeared. Now another
danger impended, and there was no time to linger, for No. 19 might be on
its way ahead if he did not reach the second switch before it moved out.
The mad run was resumed and the second switch was reached in time. As
Edwards was finishing the run to Green River, which he reached in the
morning ahead of schedule, he found written in the frost of his
cab-window these words: "A frate train was recked as yu saw. Now that yu
saw it yu will never make another run. The enjine was not ounder control
