The boy looked solemnly at Craddock, and the light of the red lamp, dim as it was, showed a certain emotion in both faces.

"That's about it, sir," said Craddock, a trifle huskily. "An' I tellin' her she'd go to 'ell! Lordy! ain't it like a woman to have the last word?"

He said no more then, but when it had been decided to return the way they had come, and take a branch line farther down, and when the trolly with its red signal had slipped back silently into the night, he came and stood at the carriage door for a moment. And as he looked at the figure crouching contentedly in the corner, he stroked his beard thoughtfully again, and went on as if no interval had come between his last words and his present ones.

"But she saved our lives, sir, by stoppin' us, that's what she done, sure as my name's Nathaniel James, and when a girl done that, a man's got nothin' left but, as the sayin' is, to act fair an' square by her--fair an' square."

"Just so, Craddock," replied the boy, with a queer stiffness in his voice. "We'll drop her at the gate again, and--and it shall be just--just as if it--as if it hadn't happened." Then he added in a lower voice, "Spin along as fast as you can, man, and let's have done with it."

"I won't leave her a hounce for a whistle, sir," said Craddock laconically.

So the carriage with the rosy light streaming through the windows shot forth into the darkness in front, and the sparks from the engine drifted into the darkness behind, and the roar and the rush drowned all other sounds. Perhaps Craddock whistled in the cab to make up for not being able to whistle on his engine. Perhaps the boy sang songs again in the carriage because he could not speak to the girl. Anyhow, they were both silent when the fly-wheel quivered into rest once more beside level crossing Number 57.

"Stop a bit," said a rather unsteady voice as a girl's figure paused against the rosy light of the open door. "It's too long a step. I'll lift you down."

Craddock, looking over the side, turned away and gave a sympathising little cough as if to cover some slighter sound. Perhaps he knew what would have happened if he had been in the boy's place.

The next instant, some one sprang into the cab and turned the steam hard on, some one with a half-pained, half-glad look on his face.
