There are little coral insects that begin to work 
down on the bottom of the ocean. They build there 
cell after cell, one upon another, like little grains 
of sand. But day by day, and year by year, these 
little insects keep cheerfully toiling on, never 
stopping to rest or play until, at length, their 
rocky dwellings reach above the water. And in this 
way beautiful islands are formed and men go and dwell on them.
