was now too intense.

"Get back with you!" ordered Harry. "Get back if you don't want a heap
worse than you gave me."

"Ha, ha! Ho, ho!" came the sneering laugh. Then the stranger reached out

"I guess I'll have to do it---though not because I really want to hurt
you!" muttered Harry ruefully.

and felt ill within himself. Yet the black man did not stagger. With a
contemptuous snort he kicked the fragment of rock into the water as it
landed at his feet.
