Why, the canoe is floating on a liquid rainbow--on a casket of jewels melted down and poured into the burning sea--on glancing shades of rose, and quivering gleams of violet, and gold and blue and amethyst and chrysophrase, all trembling and melting one into another in marvels of colouring that leave all language far behind. Under the keel, as we shoot forward, rise and sink wonderful water-bouquets of purple, pink, and pearl; great lacy fans of ivory; frilled and fluted fairy shells, streamers of brilliant weed, and under and through all these wonders glint, from far below, the dark blue depths of unplumbed caverns beneath. It is the coral reef, and we are going to land upon a spot exposed by the tide, and see what we can see of these wonders, by-and-by. If we were bent on fishing, we might spend a pleasant hour or two catching some of these peacock and parrot-coloured fish that flutter through these wonderful water-gardens. But reefing proper is more amusing, after all.
At a point where the coral juts out above the sea, we leave the canoe, and start to walk about. It is very like trying to walk on a gigantic petrified hair-brush. The coral is peaked and pointed, and wrought into honeycombed sponges of stone, and there is nowhere for the foot to rest in security. Besides, the reef is covered with sea urchins possessing spines as long and sharp as a big slate-pencil, and these things pierce through any but the stoutest shoes. The colours of the sea-urchins are fascinating, and we pick up a good many, in spite of difficulties. Then there are tiger shells, shiny and spotted, in hues of orange and brown, and beautiful scarlet and pinky and lilac and chequered shells, and the daintiest of goffered clam shells, pearl white within, ivory white without, as large as a pea-pod, or as large as a vegetable dish--you may take your choice. And, if you are lucky, there is a varnished brown snail shell that you would not think worth picking up, if you did not happen to know that it has a “peacock-eye” gem, good to set in brooches, inside its plain little front door--like the homely brown toad of fable, that carried a jewel in its head. Much other spoil there is to put in your basket, and many things that you have no desire to possess at all--among them the huge hanks of slimy black string, which are alive, and wrigglesome, and not at all pleasant to put your hand on--and the wicked-faced great eels that look suddenly out of holes, and vanish, bubbling; and the revolting, leprous-spotted fish with the spiny back, that one may chance to see lurking at the bottom of a pool, every spine charged full of deadly poison for whoever touches it with unwary foot or hand. Indeed, the friends who are with you will warn you not to put your fingers into any pool, but to hook out shells and other spoil with a stick, if you want to be really careful, for there, are as many stinging and biting things among the beauties of the coral reef, as there thorns in a bed of roses.
