"There's the president!" exclaimed Ned Foreman, and he ran forward to the front of the academy, where Professor Elliott had just been driven up in a carriage.

"I will go with you," said Frank, ranging himself up by the side of the officer. "I would like to speak to Mr. Elliott first, though."

"Certainly," acceded the constable willingly, awed by the crowd and pleased with the gentlemanly manner of his prisoner.

Professor Elliott stood awaiting the approaching crowd, staring in a puzzled way at them through his eye glasses. Frank walked straight up to him.

"Professor Eliott," he said, "I have just been arrested by this officer, on the complaint of Gill Mace, I am led to believe."

The academy president stared in astonishment at Frank, and then at Gill, who had kept up with the coterie.

"Yes, I had him arrested," proclaimed Gill.

"Indeed," spoke Mr. Elliott. "Upon what charge, may I ask?"

"He stole a diamond bracelet from my uncle's jewelry store at Tipton," declared Gill.

"There is the bracelet in question, Professor Elliott," said Frank, promptly placing a little parcel done up in tissue paper in the hands of the professor.
