Why, again, is this particular miniature dome of coral so precisely spirally fluted, like the dome of a Byzantine cathedral? Why of so pure a mauve and bespangled with so many millions of snow-white crystals? Why--where no eyes see them--should parti-coloured algae flaunt such graceful, flawless plumes? What marvellous fertility of imagination in form and design is exhibited in every quiet coral garden! Stolid battlemented walls, massive shapeless blocks, rollicking mushrooms, tipsy toadstools; narrow fjords, sparklingly clear, wind among and intersect the stubborn masses. Fish, bright as butterflies and far more alert, flash in and out of mazes more bewildering than that in which Rosamond's bower was secluded. Starfish stud the sandy flats, a foot in diameter, red with burnished black bosses, and in all shades of red to pink and cream and thence to derogatory grey. Here is a jade-coloured conglomeration of life resembling nothing in the world more than a loose handful of worms without beginning and without end, interloped and writhing and glowing as it writhes with opalescent fires; and here a tiny leafless shrub, jointed with each alternate joint, ivory, white, and ruby-red respectively; again this tracery of gold and green and salmon pink decorating a shiny stone, in formal and consistent pattern. What is it? why is it? and why are such luminous tints so sordidly concealed? CHARTER XIII SOME MARINE NOVELTIES "And call up unbound In various shapes old Proteus from the sea." MILTON. During the cool season the tides on the coast of North Queensland offer peculiar facilities to the observer of the thousand and one marvels of the tropic sea. Spring tides throughout the warm months range low at night and high during the day. In other words, the lowest day spring-tide in winter exposes far more of the reefs than the lowest day tide of summer, while the highest night tide of summer sweeps away the data of the corresponding tide of winter. When, therefore, the far receding water makes available patches of coral reef exposed at other times of the year merely to the cool glimpses of the moon, I am driven to explore them with an eagerness, if not of a treasure-seeker or in the frenzies of naturalistic fervour, at least with the enthusiasm of an ardent student. It may be that most of the sights which are revealed are of common knowledge among scientific men, and if one is inclined to preach a little sermon on the text of the living stones and polyps and animated jelly, and if such text be trite, let it be granted that the sermon is at least original. Necessarily the sermon will lack commentary and application, and be very imperfect in many other details. If it possesses any virtues, you must apply them personally, for the preacher is not enlightened enough to expound them even to his own, much less to the satisfaction of others.
