"You, sir!" exclaimed the lady, coldly. "I have heard enough of this. Don't be frightened, Miss Picolet. I only blame you for not coming to me. I have long known your circumstances, and the fact that you are poor, and that you have an imbecile sister to support, and that this man is your disreputable half-brother. And that he threatens to hang about here and make you lose your position unless you pay him to be good, is well known to me, too.

"We will have no more of this fellow's threats," continued Mrs. Tellingham, sternly. "You will give him none of your hard-earned money, Miss Picolet. Tony, here, shall see him off the grounds, and if he ever appears here again, or troubles you, let me know and I shall send him to jail for trespass. Now, remember—you Jean Picolet! I have your record and the police at Lumberton shall have it, too, if you ever trouble your sister again."

"Ah-ha!" snarled the big man, looking evilly at Ruth. "So the little Mademoiselle betrayed me; did she?"

"She has had nothing to do with it—save to have had the misfortune of losing the letter you gave her to deliver to Miss Picolet," Mrs. Tellingham said, briefly. "I had her here to identify you, had Miss Picolet not come out to meet you. Now, Tony!"

And big as the harpist was, and little as the old Irishman seemed, there was that in Tony Foyle's eye that made the man pick up his harp in a hurry and make his way from the campus.

"Child! go in to bed," said Mrs. Tellingham. "Not a word of this, remember. Thank goodness, you are one girl who can keep a secret. Miss Picolet, I want to see you in my study. I hope that, hereafter, you will give me your confidence. For you need fear no dismissal from the school over such a misfortune as is visited upon you."

She took the sobbing, trembling French teacher away with her while Ruth ran up to Duet Two in the West Dormitory, in a much excited state of mind.

Fortunately both Helen and Mercy had dropped to sleep and none of the other girls seemed to have heard the harp at midnight. So there was no talk this time about the Ghost of the Campus. To the other girls at Briarwood, the mystery remained unsolved, and the legend of the marble harp was told again and again to the Infants who came to the school, with the added point that, on the night Ruth Fielding and Helen Cameron had come to the hall, the marble harp was again heard to sound its ghostly note.

No thought of such foolish, old-wives' fables troubled Ruth Fielding's dreams as she lay down on this night which had seen the complete exposure of the campus mystery and the laying of the campus ghost. She dreamed, instead, of completing her first term at Briarwood with satisfaction to herself and her teachers—which she did! She dreamed of returning to the old Red Mill and being joyfully received by Aunt Alviry and Uncle Jabez—which she did! She dreamed, too, of joining Helen Cameron and her mid-winter party at Snow Camp and enjoying quantities of fun and frolic in the wintry woods; which, likewise, came true, and which adventures will be related in good time In the next volume of this series: "Ruth Fielding at Snow Camp; Or, Lost in the Backwoods."

"I am so glad it is over!" said Ruth to herself, as she retired. "I hope there is no more trouble."
