A volume of travel, exploration and adventure is never without instruction and fascination for old and young. There is that within us all which ever seeks for the mysteries which are bidden behind mountains, 
closeted in forests, concealed by earth or sea, in a word, which are enwrapped by Nature. And there is equally that within us which is touched most sensitively and stirred most deeply by the heroism which 
has characterized the pioneer of all ages of the world and in every field of adventure.
