"I don't know," began Jack.
"Of course you don't," interrupted Sam. "I'll attend to all that.
Come on."
Needing no more urging, Jack laid aside his book, turned his light low, and soon he and Sam were cautiously making their way from Jack's window, along a trellis and drain pipe to the ground.
"There!" exclaimed Sam, as he dropped lightly to the earth. "I feel better already. Some of the restlessness has gone."
"Keep shady," muttered Jack. "Some of the teachers have rooms near here."
They walked along under the shadow of the Hall until they came to a window from which a brilliant light streamed forth. It came from a crack between the lowered shade and the casement. It was impossible to pass it without seeing what was going on inside the apartment. At the same time they could hear the murmur of voices.
"Adrian Bagot, and his two cronies up to some trick!" whispered Jack, as he grasped Sam by the arm.
The two friends saw the three new students bending over a table, containing a pot of something, which they seemed to be stirring with a long stick.
"What are they up to?" whispered Sam.
"Experimenting with chemicals, perhaps," said Jack.
