The most remarkable if not the strangest denizens of the spot are two species of the big-eyed walking and climbing fish (PERIOPHTHALMUS KOELREUTERI and P. AUSTRALIS) which ascend the roots of the mangrove by the use of ventral and pectoral fins, jump and skip on the mud and over the surface of the water and into their burrows with rabbit-like alertness. They delight, too, in watery recesses under stones and hollows in sodden wood. Inquisitive and most observant they might be likened to Lilliputian seals, as they cling, a row of them, to a partially submerged root, and peer at you, ready to whisk away at the least sign of interference. They climb along the arching roots, the better to reconnoitre your movements and to outwit attempts at capture. Their eyes--in life, reflecting gems--are so placed that they command a complete radius, and if you think to sneak upon them they dive from their vantage points and skip with hasty flips and flops to another arching root, which they ascend, and resume their observation. It must not be assumed that the climbing fish--which seems to be more at home on the surface of the water than below--climbs up among the branches. A foot or so is about the limit of its upper wanderings. Then, too, in what is generally regarded as a noisome, dismal, mangrove swamp, birds of cheerful and pleasing character congregate. Several honey-eaters, the little blue turtle dove, the barred-shouldered dove, the tranquil dove, the nutmeg pigeon, the little bittern, the grey sandpiper, the sordid kingfisher, the spotless egret, the blue heron, the ibis--all and others frequent such places, and in their season, butterflies come and go. In most of its aspects a mangrove swamp is not only the scene of one of Natures most vigorous and determined processes, but to those who look aright, a theatre of many wonders, a museum teeming with objects of interest, a natural aviary of gladsome birds. THE UMBRELLA-TREE Having paid, in passing, respects to the most gorgeous tree of the island, it would be sheer gracelessness to withhold a tribute to one of the commonest, though ever novel and remarkable--the umbrella-tree. Less conspicuous in its blooming than the flame-tree, it flourishes everywhere--on the beaches with its roots awash at high tide; on the rearguard of the mangroves, leaning on the white-flowered CALOPHYLLUMS; on the steep hill-sides; on the borders of the jungle, and gripping scorched rocks with naked roots. While the flame-tree--few and confined to the beaches--flashes into bloom--an improvident blaze of colour, without a single atoning green leaf--the umbrella-tree charms for several months with a combination of graceful foliage and a unique corollary of singular flowers.
