NATURE FOR ITS OWN SAKE 
The whirl- 
ing world, 
erratic orbit, flinging off heat or cold as the in- 
clination of its axis to the ecliptic, it follows 
necessarily that the earth must be continually 
changing in light and color. There shall never 
be any monotony so long as the sun lasts and 
the world spins; and that light which was 
created on the earliest day is to this latest time 
the most varied and the most wonderful beauty 
of the universe.
