"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.

"If you'll please to tell me where the young lady saw it, mum," said Scott, "I'll let Bill on it sudden. He's death on rats."

"It was just at the foot of the bed," quavered Cicely. Scott stooped, and raised the valance with the greatest precaution. Bill sniffed eagerly, but he did not pounce upon any concealed victim.

"There's nothing there, mum—leastways no rat," said Scott, straightening his back.

"Are you sure?" gasped Miss Russell. "It couldn't possibly have escaped."

"I think it's been a little mistake of the young lady's, mum," said Scott, suppressing a grin. "If you'll kindly take a look under the bed, you'll see for yourself."

Miss Russell hastened to comply, and, bending down, gave an exclamation as she drew out one of Lindsay's best Sunday gloves.

"What an extraordinary illusion!" she cried. "I don't wonder Cicely took it for a rat. The soft doeskin is exactly the same colour, and the buttons were gleaming just like two bright eyes. I never saw a more perfect resemblance. I should certainly have been deceived. Well, I'm glad our chase has been a case of much ado about nothing. I think you may go to bed with easy minds to-night, girls. If we have any more alarms, we must send for Bill to protect us. Good dog! Can you find some scraps for him in the kitchen, Mrs. Wilson?"
