"On guard!" he cried, madly. "The end is not yet! I'll kill you or you'll kill me!"
There was a clash of steel, and then the fight was on with more fury than before.
Diamond was utterly reckless. He left a dozen openings where Frank could have run him through. But Merriwell was working to repeat the trick of a few seconds before.
The frightened spectators were beginning to think of intervening, when once again Diamond was disarmed.
At the same moment there came a heavy knocking at the door.
One fellow, who had been on guard, ran in from a corridor and cried:
"It's the faculty! Somebody has given them wind of this!"
"Here! here!" called a freshman. "Follow me!"
They did so, and he led them to a back window, out of which they clambered.
Diamond was the last to get out, and just as he touched the ground somebody came around the corner and grabbed him.
