Being wound up, the mouse would run swiftly across the room.
At this juncture, Frank pointed the mouse toward Nancy, and let it go, at the same time giving a squeak, which both professors distinctly heard.
Nancy saw the mouse coming, and she uttered a wild shriek of terror, clutching Professor Jenks around his slender neck.
"Save me! Save me from that terrible beast!" she squawked.
It happened that the professor was quite as scared of a mouse as Nancy could be, and he broke away and jumped up on a chair, squealing: "Murder! We'll all be bitten!" In a most remarkably skillful manner the widow sprang up to the top of the center-table, where she stood, in a stooping position, her head against the ceiling.
"Who's scared of a mouse!" sneered Professor Scotch, as he gave chase to the toy, which bumped against various pieces of furniture, and so kept dodging about.
Under the chair on which Jenks stood ran the mouse.

Scotch knocked the chair over, and Jenks uttered a wild shriek as he came down astride the little professor's neck.

Then both rolled against the center-table, which was upset.
Down came Nancy, like a balloon, nearly smothering the two professors, upon whom she alighted.
This was too much for Tad Jones, who burst into a shriek of laughter, jumped out, and extinguished the light, and shouted: "Skip, fellows--skip!" Frank and Hans lost no time in leaving their places of concealment and hustling out of the room, abandoning the two professors to their fate..
