He walked over to the window, looking out on the campus, and stood watching the flitting crowd below. Randall had come around all right, he thought, and, with a little careful handling, would soon be his old self.

Meantime, however, Randall had given a quick glance at his back. A crafty smile leaped to his face, and, while still watching Merriwell’s motionless figure, he reached out and seized the folded paper.

Tearing off one end with a quick motion, he emptied a flickering white powder into the glass that stood beside the pitcher. Still covertly eying Chip, he deftly obtained a second glass from the closet shelf and placed it on the opposite side of the pitcher. Then he poured water into both glasses.

The white powder dissolved instantly. At the sound of the pouring water, Merry turned, and Randall straightened up with a smile that set queerly on his features.

“I say, Merry,” he called, with seeming candor, “let’s drink a toast to the success of the team to-day, and the continuance of our friendship—a toast in aqua pura!”

“Bully!”

Merriwell stepped forward, with a smile. At this instant there was a sudden interruption, however.

The door was flung open, and a panting cadet orderly appeared as the startled Randall swung round.

“Mr. Randall! Colonel Gunn wants to see you at once in his office.”

This summons could mean only one thing—trouble. Randall had already slipped into his clothes, and he seized his hat, instantly forgetting everything else. Was it possible that his visit to the village of the previous night had been discovered?
