This huge, ceaseless breaker, to which I have so often alluded, was a much larger and more sublime object than we had at all imagined it to be. It rose many yards above the level of the sea, and could be seen approaching at some distance from the reef. Slowly and majestically it came on, acquiring greater volume and velocity as it advanced, until it assumed the form of a clear watery arch, which sparkled in the bright sun. On it came with resistless and solemn majesty,—the upper edge lipped gently over, and it fell with a roar that seemed as though the heart of Ocean were broken in the crash of tumultuous water, while the foam-clad coral reef appeared to tremble beneath the mighty shock!
We gazed long and wonderingly at this great sight, and it was with difficulty we could tear ourselves away from it. As I have once before mentioned, this wave broke in many places over the reef and scattered some of its spray into the lagoon, but in most places the reef was sufficiently broad and elevated to receive and check its entire force. In many places the coral rocks were covered with vegetation,—the beginning, as it appeared to us, of future islands. Thus, on this reef, we came to perceive how most of the small islands of those seas are formed. On one part we saw the spray of the breaker washing over the rocks, and millions of little, active, busy creatures continuing the work of building up: this living rampart. At another place, which was just a. little too high for the waves to wash over it, the coral insects were all dead; for we found that they never did their work above water. They had faithfully completed the mighty work which their Creator had given them to do, and they were now all dead. Again, in other spots the ceaseless lashing of the sea had broken the dead
