OFF FOR CLOVERBANK

Nan Bobbsey and some of her girl chums, as well as Danny Rugg and the boys with whom Bert Bobbsey played, also wondered why Bert had to go to the principal’s office.

“Did Bert do anything?” whispered Grace Lavine, who sat behind Nan.

“I don’t know,” was the low-voiced reply. “I don’t think so. I didn’t see him.”

“Was Bert fighting with any of the fellows?” inquired Charlie Mason of Danny, who sat near him. “Mr. Tarton doesn’t like fighting.”

“I know he doesn’t,” Danny answered. “But I don’t believe Bert was. It must be for something else.”
