Accounts of dare-devil exploits have always been read with deep interest. One Of the salient features of human nature is curiosity, a desire to know What is being said and done outside the narrow limits Of one's individual experience, or, in other words, to learn the modes of life Of persons whose environment and problems are different from one's own environment and problems. To this natural curiosity, the book of travel is particularly gratifying. But when we add to the fact that such a narrative treats of races and conditions almost unknown to the inhabitants Of civilised countries the consideration that those voyageurs to whom the adventures fell are men and women already prominently before the public, and SO deserving of that public's special confidence, the interest and value Of such a work will be seen to be extraordinarily enhanced.
