Billy, with his eyes on the track ahead, was smoking his second pipe and humming a tune, and the "Mary Ann" was making about forty miles an hour, but doing more rolling and pitching and jumping up and down than an eight-wheeler would at sixty. All at once I discerned something away down the track where the rails seemed to meet. The moon had gone behind a cloud, and the headlight gave a better view and penetrated further. Billy saw it, too, for he took his pipe out of his mouth, and with his eyes still upon it, said laconically, as was his wont: "Cow."
"Yes," said I, closing the throttle and dropping the lever ahead.
"Man," said Billy, as the shape seemed to assume a perpendicular position.
"Yes," said I, reaching for the three-way cock, and applying the tender brake, without thinking what I did.
"Woman," said Billy, as the shape was seen to wear skirts, or at least drapery.
"Mexican," said I, as I noted the mantilla over the head. We were fast nearing the object.
"No," said Billy, "too well built."
I don't know what he judged by; we could not see the face, for it was turned away from us; but the form was plainly that of a comely woman. She stood between the rails with her arms stretched out like a cross, her white gown fitting her figure closely. A black, shawl-like mantilla was over the head, partly concealing her face; her right foot was upon the left-hand rail. She stood perfectly still. We were within fifty feet of her, and our speed was reduced to half, when Billy said sharply: "Hold her, John—for God's sake!"
But I had the "Mary Ann" in the back motion before the words left his mouth, and was choking her on sand. Billy leaned upon the boiler-head and pulled the whistle-cord, but the white figure did not move. I shut my eyes as we passed the spot where she had stood. We got stopped a rod or two beyond. I took the white light in the tank and sprang to the ground. Billy lit the torch, and followed me with haste. The form still stood upon the track just where we had first seen it; but it faced us and the arms were folded. I confess to hurrying slowly until Billy caught up with the torch, which he held over his head.
"Good evening, señors," said the apparition, in very sweet English, just tinged with the Castilian accent, but she spoke as if nearly exhausted.
