It is a trick that sometimes avails to break an unsteady guard and to secure a clinch with an unwary opponent.

But Macdonald had been waiting for that trick.

Stopping short, he leaned over to one side, and stooping slightly, caught LeNoir low and tossed him clear over his head.

LeNoir fell with a terrible thud on his back, but was on his feet again like a cat and ready for the ever-advancing Macdonald.

But though he had not been struck a single blow he knew that he had met his master.
