  PREFACE

  "Dave Porter on Cave Island" is a complete story in itself but forms theeighth volume in a line issued under the general title of "Dave PorterSeries."

  The opening tale of this series, called "Dave Porter at Oak Hall,"related the adventures of a wide-awake lad at a typical boarding schoolof to-day. This was followed by "Dave Porter in the South Seas," whitherour hero had gone to find his father, and then by "Dave Porter's Returnto School."

  From Oak Hall, Dave journeyed to Norway, as related in "Dave Porter inthe Far North." On his return to this country he once more attendedschool, as told of in "Dave Porter and His Classmates." Dave made a hostof friends and likewise a few enemies, and some of the latter plotted todo him much harm.

  When vacation came once more, Dave received an invitation to visit ahome in the far west, and what he did on that trip has been set forth in"Dave Porter at Star Ranch." Then, when vacation days were at an end, hecame back to Oak Hall, as related in the seventh volume of this series,entitled, "Dave Porter and His Rivals."

  In the present book we find Dave again at school. But the Christmasholidays are at hand and the lad returns home. Here a most mysteriousand unlooked-for happening occurs, and Dave's great benefactor, Mr.Wadsworth, is on the verge of ruin because of it. Dave gets a clew tothe mystery, and, with his chums, resolves to investigate. He takes along journey and has a number of stirring adventures, the particulars ofwhich are given in the pages that follow.

  When I started this line of books I trusted that Dave might please theboys, but I did not imagine that so many thousands of boys and girls allover the land would clamor as they have for more concerning the doingsof my hero. I thank all for their appreciation of my efforts to pleasethem, and I sincerely trust that the reading of this new volume will bea benefit to them.
