"I hope it chokes you," he muttered, venomously.

Some of the passengers had descended from the day coach to stretch their limbs, and with a desire to avoid them Wade walked toward the rear of the train. Daylight dies hard up here in the mountains, but at last twilight held the world, a clear, starlit twilight. Overhead the vault of heaven was hung with deep blue velvet, pricked out with a million diamonds. Up the slope the camp-fire glowed ruddily. In the west the smouldering sunset embers had cooled to ashes of dove-gray and steel, against which Sierra Blanca crouched, a grim, black giant. Wade had reached the observation platform at the end of the sleeping-car. With a tired sigh he turned toward the slope and the beckoning fire. But the sound of a closing door brought his head around and the fire no longer beckoned.

On the platform, one hand on the knob of the car door as though meditating retreat, stood the straight, slim figure of a girl. She wore a light skirt and a white waist, and a bunch of flowers drooped from her breast. Her head was uncovered and the soft brown hair waved lustrously away from a face of ivory. The eyes that looked down into his reflected the stars in their depths, the gently-parted mouth was like a vivid red rosebud in the dusk. To Wade she seemed the very Spirit of Twilight, white and slim and ethereal, and so suddenly had the apparition sprung into his vision that he was startled and bewildered. For a long moment their looks held. Then, somewhat faintly,

"Why have we stopped?" she asked.

So unreal had she looked that his heart pounded with relief when she spoke.

"There's a hot-box," he answered, in the tones of one repeating a lesson learned. His eyes devoured her face hungrily.

"Oh!" said the girl, softly. "Then—then you aren't a robber, are you?" Wade merely shook his head. "I heard noises, and then—when I opened the door—and saw you standing there—." The first alarm was yielding to curiosity. She glanced at the scarred and stained hand which grasped the brass railing, and from there to the pleasant, eager, sunburnt face under the upturned brim of the battered sombrero. "No, I see you're not that," she went on reflectively. "Are you a miner?"

"No, only a prospector. We're camped up there." He tilted his head toward the slope without moving his gaze.

"Oh," said the girl. Perhaps she found that steady, unwinking regard of his disconcerting, for she turned her head away slightly so that her eyes were hidden from him. But the soft profile of the young face stood clear against the darkening sky, and Wade gazed enravished.

"You are looking for gold?" she asked.
