The Mighty Deep 



Newfoundland. As they journey, they slowly 

 weep and trickle out of existence. 



In the Antarctic both glaciers and icebergs are 

 abundant. The northern bergs are generally 

 higher and more sharply peaked ; the southern 

 bergs of a flatter shape, but much larger and 

 of a deeper blue. 



Sea-water does not freeze so quickly as fresh 

 water. On account of the salt which it contains, 

 it does not become solid until it is four degrees 

 colder than fresh water needs to be. The freez- 

 ing-point of fresh water is 32° F. ; that of salt 

 water is 28° F. As ocean-water freezes, most 

 of the salt is separated from it ; and the ice 

 formed is practically fresh, though often it holds 

 unfrozen salt water in tiny hollows.
