No murmur of the sea is audible, though the water is as briny as at the mouth. Mangroves still reinforce the muddy banks at intervals, and big barramundi swirl aside to give the boat precedence in the narrow way. If in no impetuous haste, one might drift with the tide up and down with but little exertion except during periods of flood, which quickly rise and quickly subside. Drifters become familiar with characteristics of the stream unknown to those who hurry up and down in an echo-rousing motor-boat. They see crocodiles basking on their sides, as many as seven on a sunny morning in the cool season, and many curse them in De Quincey's phrase as “miscreated gigantic vermin” because the rifle happens to be unavailable. Crocodiles have their moods. Sometimes they are lazy and indifferent and will not be disturbed though the boat may clink and chatter as it passes, and the then easygoing man disposes of them. More often the faculties of the crocodile are disappointingly acute. He is visible for such a fragment of time that the authoritative man who has promised sport looks foolish and tries to relieve the strain by the relation of anecdotes in which circumstances have not been all in favour of the illusive creature. He tells of the slumbering one which lay on a mud-bank with its jaws distended, weary of the monotony of the mangroves, and took but sleepy notice when upbraided for being a sluggard. And of that other monstrous beast which, with eyelids like saucers and a bulk which filled a narrow tributary of the river, floundered, splashed, and flurried into deep water, while the awestruck individual with the rifle was too astounded to fire a shot. He may tell, too, of another instance of good luck on the part of the crocodile. How, drifting down silently with the ebb, the black boy indicated the presence of game on a slide overhung by a deep verandah of mud; how a shot was fired and a big log splashed into the water and the little one remained bearing the bullet-wound, the real having been too big and impressive for sight. The day is well spent among strange plants. Here is a tall hibiscus with coarse leaves, diversely lobed, and great pink, fragile flowers, each with a blotch of maroon at the base and each containing a fat and lumbering bee spangled with maroon-tinted pollen. A trailing eugenia bears dark red flowers shaped like a mop, and a tiny white lily with petals and strangely protuberant anthers scents the air as with honey and almonds. The tide ebbs fast. All the country teems with entertainment, and the river, cool in the dusk, and black, reflects the dead mangroves, white and spectral, on its brink. This breathless night the sea is as tetchy as petrol. Trailing fingers are terminals which ignite living flames, and the propeller of the little boat creates an avengeful commotion of light which trails far astern. Blobs of light are cast off from her bows as she rounds the familiar sandspit and glides to her moorings.
