He often passed the members of his class on the street without knowing them at all; the boys said you might as well bow to a post as to Old Dimple!

But here he had taken particular notice of Bobby Hargrew; indeed, he stopped to turn around and glare right at her—just as though she had said something particularly offensive to him as he passed the group.

“Goodness!” murmured Jess. “If you’re not in trouble with Gee Gee, Bobs, you manage to get one of the other instructors down on you. What have you done to the professor?”

“Nothing, I declare!” said Bobby, plaintively.

“If you’d murdered his grandmother he couldn’t look any harder at you,” chuckled Dora Lockwood.

The professor suddenly saw that he had disturbed the party of schoolgirls. He actually flushed, and turned hurriedly to move away.

As he did so he pulled a big, blue-bordered handkerchief from the tail pocket of his frock-coat. 9 That pocket was notably a “catch-all” for anything the poor, absent-minded professor wished to save, or to which he took a fancy. Once Short and Long (otherwise a very short boy named Long) dropped a kitten into the professor’s tail pocket and the gentleman did not discover it until he reached for his bandana to wipe his moist brow when he stood up to lecture his Latin class.

However, it was nothing like a kitten that followed the blue-bordered handkerchief out of the voluminous skirt-pocket. A crumpled clipping from a newspaper fell to the walk as Professor Dimp strode away.

Bobby Hargrew’s quick eye noted the clipping first, and she darted to retrieve it. She came back more slowly, reading the printed slip.

“What is it, Bob?” asked Jess, idly.
