This unusual and popular series tells vividly the story of four adventure-loving lads, who, with their guardian, spent their summer vacations in the saddle in search of recreation and healthful adventure. Long journeys over mountain, through the fastness of primitive forest and across burning desert, lead them into the wild places of their native land as well as into many strange and exciting experiences. There is not a dull moment in the series.
