ht noise behind him, as of soft,
hurrying footsteps, caught his attention, and a woman's voice broke upon
his startled senses.

"Please don't stop, nor look around," it said, and the owner caught up
with him now in the shadow. "But will you kindly let me walk beside you
for a moment, till you can show me how to get out of this dreadful place?
I am very much frightened, and I'm afraid I shall be followed. Will you
tell me where I can go to hide?"

After an instant's astonished pause, he obeyed her and kept on, making
room for her to walk beside him, while he took the place next to the
tracks. He was aware, too, of the low rumble of a train, coming from the
mouth of the tunnel.

His companion had gasped for breath, but began again in a tone of apology:

"I saw you were a gentleman, and I didn't know what to do. I thought you
would help me to get somewhere quickly."

Just then the fiery eye of the oncoming train burst from the tunnel ahead.
Instinctively, the young man caught his companion's arm and drew her

The pent black smoke from the tunnel rolled in a thick cloud about them,
stifling them. The girl, dazed with the roar and blinded by the smoke,
could only cling to her protector. For an instant they felt as if they
were about to be drawn into the awful power of the rushing monster. Then
it had passed, and a roar of silence followed, as if they were suddenly
plunged into a vacuum. Gradually the noises of the world began again: the
rumble of a trolley-car on the bridge; the "honk-honk" of an automobile;
the cry of a newsboy. Slowly their breath and their senses came back.

The man's first thought was to get out of the cut before another train
should come. He grasped his companion's arm and started up the steep
embankment, realizing as he did so that the wrist he held was slender, and
that the sleeve which covered it was of the finest cloth.

They struggled up, scarcely pausing for breath. The steps at the side of
the bridge, made for the convenience of railroad hands, were out of the
question, for they were at a dizzy height, and hung unevenly over the
yawning pit where trains shot constantly back and forth.

As they emerged from the dark, the man saw that his companion was a young
and beautiful woman, and that she wore a light cloth gown, with neither
hat nor gloves.

At the top of the emb
