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 
erowth, — 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.
