But Mr. De Royster had felt the sneaking fingers, and had made a grab for them. He was too late, however, and, in attempting to catch Hynard he stumbled and fell.
"Come on!" cried Baker to his companions. "Let him go! We've got the stuff."
"Grab them!" cried Roy to De Royster. "I'll help you."
He rushed forward. No sooner did the swindlers see him coming, than they changed their plans. They had intended jumping on the train, which was already in motion, and leaving Mr. De Royster behind, after they had his watch and diamond.
But Roy's quickness prevented this. Baker signalled to his companions, and they ran off down the track.
"Come on!" cried Roy. "We'll catch them!"
"No! I must go to New York," replied the salesman as he arose, and brushed off his clothes. "The train is going."
"But they've got your valuables!"
"I know it. I was a fool, but it's too late now. Help me aboard."
The train was gathering headway. Roy ceased his pursuit of the robbers and helped De Royster aboard, the young man carrying his dress-suit case. Then Roy followed, while the four swindlers kept on down the railroad tracks.
