On leaving the Apure river we found ourselves in a vastly different countryside. An immense plain of water stretched out in front of us like a lake as far as the eye could see. White-topped waves rose several feet high from the clash between the breeze and the current. We no longer heard the cries of the herons, flamingos and spoonbills flying in long lines from one bank to the other. We vainly looked out for those diving birds whose busy tricks vary according to their species. Nature herself seemed less alive. Only now and then did we see between waves some large crocodiles breaking the water with their tails. The horizon was lined with a ribbon of jungle; but nowhere did the jungle reach the river. Vast beaches burned by the sun were as deserted and arid as sea beaches and, thanks to mirages, resembled stagnant marshes from afar. Rather than limiting the river these sandy banks blurred it. The banks drew near or receded according to the play of the sun's rays.
