"I have already told Dave Porter about it. I wanted his advice."

"Then request Porter to remain quiet, also," and Chip said that he would do as asked, and later on did so.

The end of the school term was now close at hand, and Dave turned to his studies with renewed vigor, resolved to come out as near to the head of the class as possible. He received several letters from Professor Potts, Mr. Wadsworth, and a delicately scented note from Jessie, and answered them all without delay. The letter from Jessie he prized highly, and read it half a dozen times before he stowed it carefully away among his few valued possessions.

On Wednesday evening Dave partook rather freely of some hash that was served up. On the sly, Sam Day salted his portion, and, as a consequence, the country boy went to bed feeling remarkably thirsty. He drank one glass of water, and an hour later got up to drink another, only to find the water pitcher empty.

"It's no use, I've got to have a drink," he told himself. "And if I catch the fellow who salted my hash——"

He slipped into part of his clothing, and, taking the water pitcher, made his way through the hallway to the nearest of the bathrooms. Here he obtained the coldest drink possible, and then, filling the pitcher, started to return to dormitory No. 12.

As he neared the dormitory, he saw somebody pass along the other end of the hallway. It was a boy, fully dressed, and with a cap set back on his head.

"Shadow Hamilton!" he murmured, as the boy passed close to a dimly burning hall light. "Now, what is he up to?"

He put down his pitcher and stole forward, until he was directly behind Shadow. Then, of a sudden, he beheld the boy swing around and put out his hands, feeling for the rail of a rear stairs. Shadow Hamilton was fast asleep.

"He is doing some more of his sleep-walking!" thought Dave. "Now, what had I best do?"
