"If you please, Mr. Allen," responded Garry, "I would like to make an appointment with you for my father and me to see you here after classes to-day." "Why, of course," replied Mr. Allen, a little surprised, as he looked at the flushed, eager face of the boy. "Would you mind telling me what it is about?" "It's about that hip-flask business," responded Garry. "I've found out who put them in my desk, as well as those of Bill Sherwood and Rooster Long." "You have?" and now it was the principal whose voice was eager. Mr. Allen had never felt easy in his mind over the penalty inflicted on the accused boys. He did not see how he could have acted other than he had, considering the weight of circumstantial evidence. The discipline of the school had to be maintained. But deep down in his heart he could not believe that Garry Grayson had lied to him. So his relief at a promised clearing up of the mystery was almost as great as that of the boys themselves. "Yes, sir," Garry replied to the principal's question. "Who did it?" asked Mr. Allen. "Anybody connected with the school?" Garry nodded his head. "But I wish you wouldn't ask me who they are just now, if you please, Mr. Allen," he said. "I don't want you to take my word for it." Here the principal flushed a little. "I'll let somebody else tell the story. Will it be all right to bring a couple of witnesses with me?" "Perfectly right," replied Mr. Allen heartily. "And I want to tell you, Garry, that nobody will be more delighted than I if their story clears you of all connection with the matter." Garry thanked the principal and was off to telephone Cal Yates. The latter was at home, and agreed to go out in his car, get Jake, and bring him along. Promptly at the appointed time, Garry and his father, together with Cal Yates, were gathered in Mr. Allen's office. Jake was waiting outside, since Cal had promised to secure from Mr. Allen a pledge that Jake's name would be kept out of the matter as far as possible. "Now, Garry," said Mr. Allen, as he settled down in his chair, "you have the floor. Bring on your witnesses." "This is the first one," said Garry, introducing Cal. The latter plunged at once into the story, telling the facts clearly and convincingly. Mr. Allen was visibly impressed. He put a number of questions, all of which were answered frankly and without the slightest hesitation. "Now for the other witness," he said. Then Cal told of the presence of Jake outside and of his anxiety to avoid publicity. Mr. Allen conferred in low tones with Mr. Grayson, and then gave the required promise. Jake was brought in and, with much twisting and squirming, confirmed Cal's story. He was an unwilling witness, and for that reason his statements carried the more weight. The next morning a messenger from the principal came into the junior class in Latin and spoke to Mr. Blythe in a whisper. "Podder and Stewart," announced the Latin teacher, "you will report at once to Mr. Allen in his office!"
