Mac did come again, glad to find something he could study in spite of his weak eyes, and learned much that was of more value than any thing his school had ever taught him.
Of course, the other lads made great fun of the whole thing, and plagued Dr. Alec's students half out of their lives. But they kept on persistently, and one day something happened which made the other fellows behave themselves for ever after.
It was a holiday, and Rose up in her room thought she heard the voices of her cousins, so she ran down to welcome them, but found no one there.
"Never mind, they will be here soon, and then we'll have a frolic," she said to herself, and thinking she had been mistaken she went into the study to wait. She was lounging over the table looking at a map when an odd noise caught her ear. A gentle tapping somewhere, and following the sound it seemed to come from the inside of the long case in which the skeleton lived when not professionally engaged. This case stood upright in a niche between two book-cases at the back of the room, a darkish corner, where Brother Bones, as the boys would call him, was out of the way.
As Rose stood looking in that direction, and wondering if a rat had got shut in, the door of the case swung slowly open, and with a great start she saw a bony arm lifted, and a bony finger beckon to her. For a minute she was frightened, and ran to the study door with a fluttering heart, but just as she touched the handle a queer, stifled sort of giggle made her stop short and turn red with anger. She paused an instant to collect herself, and then went softly toward the bony beckoner. A nearer look revealed black threads tied to the arm and fingers, the ends of threads disappearing through holes bored in the back of the case. Peeping into the deep recess, she also caught sight of the tip of an elbow covered with a rough gray cloth which she knew very well.
Quick as a flash she understood the joke, her fear vanished, and with a wicked smile, she whipped out her scissors, cut the threads, and the bony arm dropped with a rattle. Before she could say, "Come out, Charlie, and let my skeleton alone," a sudden irruption of boys all in a high state of tickle proclaimed to the hidden rogue that his joke was a failure.
"I told him not to do it, because it might give you a start," explained Archie, emerging from the closet.
"I had a smelling-bottle all ready if she fainted away," added Steve, popping up from behind the great chair.
"It's too bad of you not to squawk and run; we depended on it, it's such fun to howl after you," said Will and Geordie, rolling out from under the sofa in a promiscuous heap.
"You are getting altogether too strong-minded, Rose; most girls would have been in a jolly twitter to see this old fellow waggling his finger at them," complained Charlie, squeezing out from his tight quarters, dusty and disgusted.
