Now it so happened that Professor Tines was just leaving the dormitory. He had called to see one of his pupils who was ill--a "greasy dig" student--to use the college vernacular to designate a lad who burned midnight oil over his studies. The professor having finished his call came upon Sid in the corridor. The instructor saw before him a young man, mud covered, carrying a square, black box, and the countenance, spotted with specimens of swamp muck, was unfamiliar to him. Professor Tines at once suspected a student trick.
