Since those first days at school many changes had taken place; so many, in fact, that but a few can be noted here. Crabtree had been discharged, and was now in prison for trying to hypnotize a lady into marrying him. This lady was Mrs. Stanhope, the mother of Dora Stanhope, who lived in the vicinity of Putnam Hall, and a girl of whom Dick Rover thought a good deal.
It had not taken the Rover boys long to discover that not only the dictatorial old teacher, but also the bully, Dan Baxter, were rascals, and, what was more, that Arnold Baxter, the father of Dan, was an old enemy to their father. Following this had come a journey to Africa and into the jungle in search of Mr. Rover, and this mission accomplished, the Rover boys had gone West to establish a mining claim in which their father was interested. This claim was disputed by the Baxters, and when the Rovers won out and went for a pleasure trip on the Great Lakes, the Baxters did their best to bring Dick, Tom, and Sam to grief. But instead of accomplishing their purpose they failed once more, and Arnold Baxter was returned to the prison from which he had escaped some months before. What had become of Dan Baxter nobody knew, but the Rover boys were soon to learn, as we will see in the chapters which follow.
