“What are you doing?” he demanded, and then a long string of the firecrackers went off, causing him to whirl first to one side and then another. He put his hands behind him. “Ouch! I’m burnt!” he screamed.

“Whoopla! that’s the way to celebrate!” roared Spud. “Nothing like having fun while you are at it!”

“I’ll ‘fun’ you!” yelled Filbury, in anger, and of a sudden he drew off his coat and commenced to chase Spud. Down the corridor went the pair. And then Filbury cast the coat with the firecrackers still exploding, at Spud’s head.

Spud ducked and the coat sailed over his head, to enter a doorway that was partly open. Then another person appeared. It was Professor Asa Sharp. He stepped on the coat and as he did so several of the firecrackers went off, one hitting him directly in the chin.

“Oh!” he screamed. “I am hit! Take those fireworks away!” And he bolted down the hallway with all the speed he could command. He ran out on a porch and then down on the campus, where Tom and Sam were bending over something on the ground.

“Look out! Run!” yelled Tom, and then he and his brother leaped back. In bewilderment Professor Asa Sharp stood still. Then a terrific explosion rent the air, and a great shower of sparks flew in all directions.

“Say, that was an explosion!”

“Who was that stood so close?”

“Was he hurt?”
