200 AGE OF CORAL REEFS. 
of the same Intellect through all time, every- 
where. 
When we observe the practical results of this 
sequence in the position of Corals on the reef, 
we cannot fail to see that it is not a mere acci- 
dental difference of structure and relation, but 
that it bears direct reference to the part these 
little beings were to play in Creation. It places 
the solid part of the structure at the base of the 
Reef, —it fills in the interstices with a lighter 
growth, — it crowns the summit with the more 
delicate kinds, that yield to the action of the tides 
and are easily crushed into the fine sand that 
forms the soil,—it makes a masonry solid, 
compact, time-defying, such a masonry as was 
needed by the great Architect, who meant that 
these smallest creatures of His hand should help 
to build His islands and His continents.
