It was a forlorn old hat, of light-gray felt, but soiled and torn, and Betty’s frightened heart told her that it was the hat of some marauder, and not of any member of the Carey family.

With a sudden scream, which she could not repress, she ran and hid behind a large Japanese screen in the corner of the room.

“Who’s there?” called a man’s voice from the hall. It was a loud, gruff voice, and poor Betty shook and shivered as she crouched behind the screen.

“Who’s there?” repeated the voice, and Betty heard heavy footsteps coming in at the living-room door.

Then there was silence. The man was apparently awaiting Betty’s next move. Then he said again: “Who screamed just now? Where are you?” and somehow this time his voice did not sound quite so ferocious. But Betty had no intention of answering, and she squeezed into her corner, hoping that he would go away.

Then suddenly the whimsical idea came to her that, as she was personating Robinson Crusoe, this was probably the Man Friday who had arrived. This amused her so much that she giggled in spite of her fear. The man heard the smothered sound, and going straight to the screen, he pulled it suddenly away.

Betty, who was sitting on the floor, looked up to see a stalwart young man of a college type staring down at her. His costume of summer outing clothes was informal, but at once betokened he was no marauder. Also, his handsome, sunburnt face and frank blue eyes showed a kindly though surprised expression.

Betty was reassured at once, and, truly glad to see a human being of her own walk in life, her face broke into smiles and merry dimples, as she said:

“Hello, Man Friday!”

“Who are you?” was his bewildered response, and then remembering himself, he added: “I beg your pardon; may I assist you to rise?”
