The instructor flashed a rather wondering look at the girl of the Red Mill; then she smiled. It was a grouty person, indeed, who could look into Ruth Fielding's frank countenance and not return her smile.

"Bless you! I have heard of you already, Ruth Fielding. I have no idea I shall be troubled by you or your friends." They had fallen behind the others a few steps. "But we never can tell. Since last term—well!"

Much, evidently, was on Miss Cullam's mind; yet she kept step with Ruth when they came to the corridor on which the rooms of the three Briarwoods opened. Ruth could always find something pleasant to say. This woman with the care-graved countenance smiled whimsically as she listened, keeping at the girl's shoulder.

Evidently somewhat oppressed by the attentions of the instructor, Helen and Heavy had disappeared into the fleshy girl's room.

"Do come in and see how nicely we have fixed our sitting-room—study, I mean, of course," and Ruth laughed, opening the door.

"Looks homelike," confessed Miss Cullam. Then, with a startled glance around the room, she murmured: "Why, it's the very room!"

"What is that you say?" asked Ruth, curiously.

"Do you know who had this room last year?"

"Of course I haven't the first idea," returned the girl of the Red Mill.

"Miss Rolff."
