In his rage he ran over to Tom and caught him by the ear.
He had scarcely done so than Tom put out one foot, gave the teacher a shove, and down went Crabtree flat on his back.
"You villain!" gasped the head assistant, as he scrambled to his feet.
"Don't you pinch my ear again," retorted Tom.
The door was open, and before Crabtree could stop him he ran out into the hallway.
"Hold on!"
"Not much!"
"It will be the worse for you!"
"I'll risk that."
"Stop him, somebody!" screamed Josiah Crabtree at the top of his voice.
