Caves and caverns in the rocks and the tops of the mountains are not favourite resorts of blacks. According to them nearly every mountain has its mysterious lagoon, which none but old men have visited, but which teems with fish and waterfowl. When direct inquiries are made as to the precise locality of any particular lagoon, invariably inconclusive evidence is tendered. "Old man, he bin see 'em;" and, the old man is never forthcoming for cross-examination. The origin of the romance, no doubt, is to be attributed to the desire of the blacks to account to themselves for the water which glitters on the face of the rocks far up the mountains. One boy gave an exceptionally graphic description of a lagoon on the top of one of the highest peaks of Hinchinbrook Island, in which all manner of sea fish revelled. When doubt was expressed as to the possibility of sea-water and sea-fish getting up so far "on top" and it was suggested--"What you think, that old man humbug you?" "Yes," was the ready response; "me think that old fella no tell true. Him humbug." Some blacks possess something wiser than knowledge. On the northern aspect of Dunk Island, where the sea swirls about the buttresses of the hills, there is a cavern only approachable by boat. The mouth is overhung by vines and ferns, and through the moss which covers the lintel water trickles and splashes with pleasant sound. When the bronze orchid lavishly decorates the rocks with its crinkled flowers of dull gold, the entrance has a specific character; and quite another when the glossy leaves of the umbrella-tree form the relief and its long radiating spikes of dull red, bead-like flowers attract the brilliant sun-bird, and big blue and green and red butterflies. Even when the sea is lustrous the cavern, with all the artfulness and grace of the decorations of its portals, is a black blotch--the entrance to something unknowable and unknown--at least to the blacks. None had ever ventured near it and they never will. They tell you how it came to be made. How a long, long time ago, a big man, "all a same debil-debil," took out with his mighty fingers a plug of rock and put it "on top alonga Hinchinbrook." Now the particular decapitated pinnacle of Hinchinbrook is 20 miles away, and out of all proportion. But these facts do not affect the legitimacy of the legend. There is the hole, and there on the top of the far-away mountain the prodigious plug demonstrative evidence too obvious to be set aside on any such plea as the eternal fitness of things. Is not the blue point of the mountain a defiantly triumphant fact? Is not the legend authenticated by tradition and confirmed by topography? Why, therefore, doubt it for a moment? And the hole--it goes a long, long way under the mountain. It is a bad place, a very bad place. No one has ever been there. Suppose any fella go inside, bi'mby that fella sick, bi'mby that fella die.
