'Let go!' cried the rider.

'Not until you have told me where you live, and where you may be found. I have searched for you in vain. I will have my revenge; I will force you to do justice. You——'

He reared bolt upright, he kicked, he plunged; and, finally, he shook off the obnoxious control, to dash furiously in the direction of the gravel pits. Miss Gwinn fell to the ground.

To fall into the pit would be certain destruction to both man and horse. Austin Clay had watched the encounter in amazement, though he could not hear the words of the quarrel. In the humane impulse of the moment, disregarding the danger to himself, he darted in front of the horse, arrested him on the very brink of the pit, and threw him back on his haunches.

'Young gentleman, you have saved my life.'

There was little doubt of that. Austin accepted the fact without any fuss, feeling as thankful as the speaker, and quite unconscious at the moment of the wrench he had given his own shoulder.

'It would have been an awkward fall, sir. I am glad I happened to be here.'

'It would have been a killing fall,' replied the stranger, stepping to the brink, and looking down. 'And your being here must be owing to God's wonderful Providence.'
