When he returned to school many strenuous happenings awaited him, and what they were will be found in "Dave Porter and His Rivals."
Dave had lived for years with a rich manufacturer of jewelry, and when this man was robbed it was our hero who followed the criminals in a long flight, as told in "Dave Porter on Cave Island." Then, with the booty in his possession, the youth returned home, to go back to school, from which he soon after graduated with honors, as shown in the volume preceding this, entitled, "Dave Porter and the Runaways."
In the present volume are related the particulars of another trip West, taken by Dave and his chums to locate a lost gold mine, willed to Roger Morr's mother by her brother. The boys had some strenuous happenings, and some of their old-time enemies did all they could to bring their expedition to grief. But Dave showed his common sense and his courage, and in the end all went well.
Once again I thank my young readers for the interest they have shown in my books. I trust that the reading of this volume will benefit them all.
