SAFETY OF THE MARINER. 775 



tions unexplored grow smaller and smaller, so that we are 

 justified in believing that eventually the whole world will be 

 known to us, from actual observation. 



Another difference which our extended knowledge of the 

 world has produced is this : The mariner now approaching 

 an unknown coast does not fear to meet monsters, but looks 

 out for the light-house, the light- ships, the buoys, and othei 

 evidences of civilization, by which the dangers of the coast 

 are pointed out to the voyager. As a contrast with some of 

 the pictures already given, representing the approach to 

 the land of the early explorers, the illustration of the light- 

 ship will show how differently to-day a voyage approaches its 

 termination. Instead of looking out for enemies, and prepar- 

 ing weapons for use, a package of newspapers and letters is 

 got ready, and the news boat, which lies ready at hand, is 

 prompt to seize them, and hasten with these to spread the 

 news of another safe arrival. It is thus that science, 

 which is gradually preparing the means for converting the 

 globe into one great organism for the benefit of mankind, 

 points out the way for making it the abode of that harmony, 

 peace and plenty which has been dreamed of by the poets of 

 all time. For this it is only necessary that our moral progress 

 should keep pace with our advance in knowledge. The globe 

 will never become the abode of perfect harmony until men 

 are united in a universal league of justice and peace. And 

 n aiding toward the production of this most desirable con- 

 summation, what has been here written will show how 

 important has been the part taken by the ocean.
