The long train, which for nearly an hour had been gliding smoothly
forward with a soothing, cradling motion of its heavy trucked Pullmans,
and a crooning, lullaby sound of its droning wheels, came to a jarring
stop at one of the mountain stations, and Lieutenant Allison wakened
with a start. The echo of the laugh that he had heard in his dream still
sounded in his ears, a tantalizing, compelling note, elusive as the
Pipes of Pan, luring as a will-o'-the-wisp.
