The dean nodded to show that he understood.
"Now, then," continued the professor, "I had the papers printed by the college printer in the usual way, with just enough copies to go around.
"I counted the papers when they were delivered at my room by the printer, and found them to be one hundred and forty-six in all. I tied the papers up in a parcel and left them in my room until this morning, when I took the parcel to Osborn Hall. There I opened the bundle and when the papers were distributed, it proved that two were missing."
Prof. Babbitt paused, as if expecting the dean to make some comment. He did not do so, but looked straight ahead, and so the professor went on.
"I must say that I instantly had my suspicions of Merriwell, for during the past three days he has been frequently at the house where I have my room.
"I kept my eyes on him during the entire examination, and I could easily see that he was not conducting himself as usual. He used up a great deal of paper and was evidently nervous.
"At length I took a position back of his desk, where I could watch what he was doing without being observed. Presently I saw him work out the last problem on the examination paper, and work it out correctly, too.
"Then, as he crumpled up the paper on which he had been figuring, I caught a glimpse of the other side of it. I pounced upon his hand and discovered that he had been figuring upon the back of one of the missing question sheets."
The professor's voice had a triumphant ring when he came to the end of his little speech. There was evidently no doubt in his mind that what he had discovered would be sufficient proof to the dean of Frank's crookedness.
The dean pursed up his lips and looked absently up at the ceiling for a moment, and then turned to Frank.
