object to the presence
of a perfectly harmless stranger?"

Partly with cold, partly with nervousness, David shivered.

"I wish that train would come," he sighed. And instantly, as though in
answer to his wish, from only a short distance down the track he heard
the rumble and creak of approaching cars. In a flash David planned his
course of action.

The thought of spending the night in a swamp infested by alligators and
smugglers had become intolerable. He must escape, and he must escape by
the train now approaching. To that end the train must be stopped. His
plan was simple. The train was moving very, very slowly, and though he
had no lantern to wave, in order to bring it to a halt he need only
stand on the track exposed to the glare of the headlight and wave his
arms. David sprang between the rails and gesticulated wildly. But in
amazement his arms fell to his sides. For the train, now only a hundred
yards distant and creeping toward him at a snail's pace, carried no
headlight, and though in the moonlight David was plainly visible, it
blew no whistle, tolled no bell. Even the passenger coaches in the rear
of the sightless engine were wrapped in darkness. It was a ghost of a
train, a Flying Dutchman of a train, a nightmare of a train. It was as
unreal as the black swamp, as the moss on the dead trees, as the ghostly
tug-boat tied to the rotting wharf.

"Is the place haunted!" exclaimed David.

He was answered by the grinding of brakes and by the train coming to a
sharp halt. And instantly from every side men fell from it to the
ground, and the silence of the night was broken by a confusion of calls
and eager greeting and questions and sharp words of command.

So fascinated was David in the stealthy arrival of the train and in her
mysterious passengers that, until they confronted him, he did not note
the equally stealthy approach of three men. Of these one was the little
man from the tug. With him was a fat, red-faced Irish-American. He wore
no coat and his shirt-sleeves were drawn away from his hands by garters
of pink elastic, his derby hat was balanced behind his ears, upon his
right hand flashed an enormous diamond. He looked as though but at that
moment he had stopped sliding glasses across a Bowery bar. The third man
carried the outward marks of a sailor. David believed he was the tallest
man he had ever beheld, but equally remarkable with his height was his
beard and hair, which were of a fierce brick-dust r
