The sun was at its zenith; it darted down its perpendicular light from a sky of violet grey, leaden grey, dim with the miasma of the swamps. The heat was so appalling that the black oarsmen, in spite of all their pluck, were obliged to take a rest. The tepid water could no longer quench their thirst; they were exhausted, and seemed to be melting away in perspiration. And then, when they halted, the pirogue, carried gently along by an almost imperceptible current, drifted onwards. The spahis could study at close quarters a whole strange world, the underworld that had its being beneath the mangroves and peopled all the marshes of equatorial Africa. In the shade, in the obscure network of great roots, this world lay asleep. There, two steps away from the canoe, which glided past without a sound, stealing by so quietly that not even the birds were awakened—near enough to touch it—lay dull-green crocodiles, their sleek forms stretched out on the mud, yawning and grinning idiotically with gaping viscous jaws. There were graceful white herons asleep likewise, snowy white balls, standing on one leg, and to avoid contact with the mud actually perched on the backs of the crocodiles in their trance-like sleep. There were kingfishers of every shade of green and blue taking their noonday rest by the water’s edge, in the company of sluggish lizards and great, wonderful butterflies that had come to life in a temperature like a boiler’s, slowly folding and unfolding their wings wherever they happened to alight, resembling dead leaves when their wings were closed, brilliant as mysterious jewels when their wings were spread, all glittering with blue enamel and metallic gleams. Above all, there were roots of mangrove trees, roots and still more roots, trailing down everywhere, like sheaves of filaments; roots of all lengths and thicknesses, falling in tangled masses from every direction. You would have said thousands of nerves, tentacles, grey arms, eager to enmesh and envelop all things. Great stretches of country were covered with these entanglements of roots. And swarming all over the mud and the roots and the crocodiles were colonies of great grey crabs, continually brandishing their single pair of ivory white pincers, as if seeking in dreams to clutch an imaginary prey. The somnambulistic movement of all these crabs under the dense verdure was the only sign of life perceptible throughout this sleeping universe. * * * * * When the black oarsmen had recovered their breath, they resumed, in low voices, their wild singing, and rowed furiously. Then the spahis’ pirogue cut through the quiet waters of the Diakhallémé and sped down the winding river, gliding very swiftly through the heart of the forests.
