“He didn’t say; but he wants you to come at once.”

“Very well, Donald; where is he?”

“In the library.”

Oliver rose to his feet somewhat slowly. He was in no humor just then to face his respected sire. A few words will explain why.

Oliver was afraid he was in for a lecture, and perhaps worse. He was not a boy of bad disposition, but for once the combination of circumstances had led him into serious difficulty.

Oliver was a student at the Rockvale Academy, also catcher for the local baseball nine. Two days before, on the very afternoon that the nine was to play an important game with the club from Elmport, Oliver had been kept in by Dr. Tangus for a supposed fault of which he was not guilty. This had angered Oliver, and as his particular chum, Gus Gregory, was kept in at the same time, the two planned to “get square,” as they termed it.

Their plan of action was simple and harmless enough, but it bore grievous results. Gus proposed to take the doctor’s pet calf from her pasture and lead her into the schoolroom, and Oliver agreed that if this was done he would make the old cow follow.

At dead of night the two boys started to carry out their plan. But both the calf and the cow made such a noise that the doctor’s whole household was aroused, and the two boys had to run for it.

In making their escape Gus Gregory had stumbled over a hothouse bed, smashing a dozen panes of glass or more, thus provoking a shot from the doctor’s hired man, who imagined burglars were around.

When Oliver reached home he found he had quite a severe cut upon his left hand, obtained in his effort to help Gus out of the hotbed frame.
