280 THE OCEAN. 



Expanded like a sky above the speck ; 



That speck became a hand-breadth; day and night 



It spread, accumulated, and ere long 



Presented to my view a dazzling plain, 



White as the moon amid the sapphire sea; 



Bare at low water, and as still as death ; 



But when the tide came gurgling o'er the surface, 



'Twas like a resurrection of the dead; 



From graves innumerable, punctures fine 



In the close coral, capillary swarms 



Of reptiles, horrent as Medusa's snakes, 



Cover'd the bald-pate reef; then all was life, 



And indefatigable industry ; 



The artizans were twisting to and fro, 



In idle-seeming convolutions; yet 



They never vanish'd with the ebbing surge, 



Till pellicle on pellicle, and layer 



On layer, was added to the growing mass. 



Ere long the reef o'ertopped the spring-flood's height, 



And mock'd the billows when they leap'd upon it, 



Unable to maintain their slippery hold, 



And falling down in foam-wreaths round its verge. 



Steep were the flanks, with precipices sharp, 



Descending to their base in ocean-gloom, 



Chasms few, and narrow, and irregular, 



Form'd harbours, safe at once and perilous — 



Safe for defence, but perilous to enter. 



A sea-lake shone amidst the fossil isle, 



Reflecting in a ring its cliffs and caverns, 



With heaven itself seen like a lake below."* 



The islands of the second class seem to have been 

 originally of the same structure as those already 

 noticed, but have been elevated to the height of 

 one hundred to five hundred feet, byisome unknown 

 agency. The character of their vegetation resem- 

 bles that of the volcanic isles, of which I shall pre- 

 sently speak, but they do not possess their sub-
