gradually rise, owing to its restricted area, 

 until it would again cover the whole earth as 

 it undoubtedly did at one time in the earth's 

 history. This fact need not occasion any un- 

 easiness on the part of those who are living 

 to-day or for millions of years to come. 



The problem of building a world and then 

 tearing it to pieces is a very complicated one. 

 There is a constant battle going on between 

 the powers that build up and those that tear 

 down; and this is as true of character-build- 

 ing as it is of world-building. The world has 

 never been exactly alike any two successive 

 days from the time its foundations were laid 

 to the present moment. It seems to be a fun- 

 damental law of all life and growth, as well as 

 of all decay, that there shall be a constant 

 change. There is no such thing as rest in 

 nature. The smallest molecules and atoms of 

 matter are in constant agitation. In the ani- 

 mal and vegetable world there is a period of 

 life and growth, and a period of decay and 

 death; and this seems to be the destiny of 

 planets themselves as well as the things that 

 live and grow upon them. Still, science 

 teaches us that with all this turmoil and 

 change nothing either of matter or energy is 

 lost, but that it is simply undergoing one eter- 

 nal round of change. Does this law apply to 

 mind and soul? Do we die? Or do we 

 simply change?
