"I think you did wisely to let them go," he remarked. "Unless we were under the protection of their chief man, or king, as he is called, we could not tell how they might behave. We must use great caution in our intercourse with these people. When we have shown them that we are friends, and desire to do them all the good in our power, we, I hope, shall find them faithful; but they have become so debased by their intercourse with the white people, and especially, I am sorry to say, with my countrymen, who often deal treacherously with them, that they cannot be depended on. They in return, as might naturally be supposed, cheat and deceive the whites in every way." Our path first led through the forest near the banks of the river, of which we occasionally got glimpses. It was here of considerable width, bordered by mangrove bushes. In one or two places there were wide flats covered with reeds. Suddenly, as we passed a point of the river, I saw drawn up what had much the appearance, at the first glance, of a regiment of soldiers, with red coats and white trousers. "Why, where can those men have come from?" I cried out. David, who was near me, burst into a laugh, in which his sisters and the boys joined. "Why, Andrew, those are birds," he answered. "A regiment, true enough, but of flamingoes; and see! they are in line, and will quickly march away as we approach." A second glance showed me that he was right; and a very curious appearance they had. "See! there is the sentinel." As he spoke, one of the birds nearest to us issued a sound like that of a trumpet, which was taken up by the remainder; and the whole troop, expanding their flaming wings, rose with loud clamours into the air, flying up the stream. We went on, and cutting off a bend in the river, again met it; and here our bearers declared that they must stop and rest. We accordingly encamped, though Senhor Silva warned us that we must remain but a short time, as we wished to reach some higher ground before dark. A fire was lighted for cooking; and while our meal was preparing, David and I, with the two boys, went down nearer the banks to see what was to be seen. We observed on the marshy ground a little way off a high mound, and creeping along, that we might not disturb the numerous birds which covered the banks or sat on the trees around, we caught sight of another mound, with a flamingo seated on the top of it, her long legs, instead of being tucked up as those of most birds would have been, literally astraddle on it. "That is one of their nests," whispered David. "The bird is a hen sitting on her eggs. Depend upon it, the troop is not far off. See, see! there are many others along the banks. What a funny appearance they have."
