At all events, they were now scarcely a quarter of a mile from the forest, which they knew stretched along the horizon as far as they could have seen had it been daylight. They could only just distinguish a dark belt or line rising above the surface of the water before them; but that this extended right and left to a far distance could be told from the sounds that came from it. There was the hum of tree-crickets and cicadas, the gluck of toads and frogs, the screams of aquatic birds, the hooting of owls, and the strange plaintive calls of the goat-suckers, of which several species inhabit the Gapo forests; the whip-poor-will and the “willy-come-go” all the night long giving utterance to their monotonous melody. Harsher still were the cries proceeding from the throats of howling monkeys, with now and then the melancholy moaning of the aï, as it moved slowly through the branches of the embaüba (cecropia-tree). All these sounds, and a score of other kinds,—some produced by insects and reptiles of unknown species,—were blended in that great choir of nature which fills the tropical forest with its midnight music.
The two swimmers, however, paid no attention to this fact; their whole thoughts being occupied by the lights, that, as they advanced, grew every moment more conspicuous. There was no longer any doubt about these being the blaze of fires. It was simply a question of where the fires were burning, and who had kindled them.
The young Paraense supposed them to be upon the shore of the lagoa. About this, however, his companion expressed a doubt. They did not seem to burn steadily, their discs appearing now larger and now less. Sometimes one would go out altogether, then blaze up afresh, while another was as suddenly extinguished. The younger of the two swimmers expressed astonishment at this intermittence, which his companion easily explained. The fires, he said, were placed at some distance from the edge of the forest, among the trees, and it was by some tree-trunk now and then intervening that the illusion was caused.
Silently the swimmers approached, and in due time they glided in under the shadow of the thick foliage, and saw the fires more distinctly. To the astonishment of Richard—for the tapuyo did not seem at all astonished—they did not appear to be on the ground, but up in the air! The Paraense at first supposed them to have been kindled upon the top of some eminence; but, on scanning them more closely, he saw that this could not be the case. Their gleaming red light fell upon water shining beneath, over which, it was clear, they were in some way suspended.
As their eyes became accustomed to the glare, the swimmers could make out that the fires were upon a sort of scaffold raised several feet above the water, and supported by the trunks of the trees. Other similar scaffolds could be seen, on which no fires had been kindled,—from the fact, no doubt, that their occupants were not yet astir.
By the blaze human figures were moving to and fro, and others were on the platforms near by, which were more dimly illuminated; some entering, some coming forth from “toldos,” or sheds, that stood upon them. Hammocks could be seen suspended from free to tree, some empty, and some still holding a sleeper.
All this was seen at a single glance, while at the same time were heard voices, that had been hitherto drowned by the forest choir, but could now be distinguished as the voices of men, women, and children,—such as might be heard in some rural hamlet, whose inhabitants were about bestirring themselves for their daily avocations.
The tapuyo, gliding close up to the Paraense, whispered in his ear, “A malocca!”
“An Indian village!” Richard rejoined. “We’ve reached tierra firme, then?”
“Not a bit of it, young master. If the dry land had been near, those fires wouldn’t be burning among the tree-tops.”
