"Baseball Joe" Matson's great ambition is to go to boarding school and play on the school team, in this second volume of the Baseball Joe series. Joe is a wide-awake country boy who enjoys playing baseball. We follow his career in the series, and his adventures, as he and hometown chum Tom Davis enroll in Excelsior Hall and join the school nine, are recounted here. When not on the diamond, Joe is saving lives and assisting his father against foes who are once again trying to steal Mr. Matson's machinery patents.
