Nora Proctor and Marjorie Butler awoke half the school one night by loud and repeated screams, and when Miss Frazer rushed into their room, imagining fire or burglars, she found them cowering behind the bed curtains, in mortal terror of a large bat that had made its way through the open casement. Earwigs were a constant nuisance, and everyone grew almost accustomed to catching green caterpillars, which crept in from the roses that surrounded the windows, and would turn up in the most undesirable spots. Naturally so old a house was infested with rats and mice. They scuttled inside the walls, and squeaked behind the wainscots, and seemed to hold carnival at the back of the oak panelling, often disturbing the girls at night with the noise. This was particularly noticeable in the room where Lindsay and Cicely slept. They were sometimes awakened by sounds like the rolling of barrels overhead, as if heavy objects were being clanked about up in the ceiling. "You've no need to be afraid of them," said Mrs. Wilson, who made light of all complaints, "they never venture out of the walls, to my knowledge." The fear, however, that a rat might possibly gnaw its way into her bedroom afflicted Cicely continually. "If it ran across my pillow I should die of fright, I know I should!" she wailed. "I wish Mrs. Wilson would let us have the cat to sleep with us. I should feel far safer." "I wish we could send for the Pied Piper, and get rid of them all. They woke me twice last night," said Lindsay. Poor Cicely never dared to retire without first having a thorough examination to assure herself that no lurking rodent was lying hidden behind the wardrobe, or in any other obscure corner. One evening she was making her usual round, armed with a tennis racket for protection, and was peeping under the bed, when she suddenly let the valance fall hurriedly, and drew back with a shriek. "There's a rat there! I saw it quite plainly; its great big eyes were glaring at me!" she announced in a trembling voice. "What are we to do?" exclaimed Lindsay, in equal consternation. "Call for Miss Frazer this instant. She hasn't gone downstairs yet." "Don't disturb it on any account!" decreed Miss Russell, who was fetched from the drawing-room to cope with the emergency. "I shall send at once for Scott, the gardener, and ask him to bring his terrier dog. We must really take some measures to destroy these pests." It was not very long before Scott arrived. He clumped solemnly up the stairs with a thick stick in his hand, and Bill, his sharp little fox terrier, at his heels. Mrs. Wilson accompanied him, bearing the kitchen poker; and the parlour-maid followed, holding the yard dog by the collar, in case Bill should miss his prey. Miss Frazer and Miss Humphreys were there to support Miss Russell; while Mademoiselle and a great many of the girls hovered outside in the passage, half-frightened and half-excited over the coming fray.
