Professor Elias Rodd was rather elderly, and, as he never took much exercise, his sprinting abilities were not pronounced. So it took him about a minute and a half to cross the campus to where the little group of lads awaited him--anxious waiting it was too, on the part of Joe and Peaches. And in that minute and a half, before the excitement begins, I want to take the opportunity to tell you something about Joe Matson, and his chum Tom Davis, and how they happened to be at Excelsior Hall.
