The three students left the dormitory, and from another lad learned that Nat was in the library. They sent a small boy after him, stating that he was wanted at once at the "den," a room where the students sometimes congregated, but which just then was deserted.

"Found it just where you lost it—in Luke Watson's slipper."
"Eh?" And Nat looked startled.
"Nat, we have found you out!" cried Shadow, sternly. "You needn't attempt to deny it. You took those shoes, boots, and slippers."
