For this reason they could put no dependence in their sail, and would have to trust altogether to the paddles. These could not be always in the water. Human strength could not stand a perpetual spell, even at paddles; and less so in the hands of a crew of men so little used to them. Nor could they continue the voyage at night. By doing so, they would be in danger of losing their course, their craft, and themselves! You may smile at the idea. You will ask--a little scornfully, perhaps--how a canoe, or any other craft, drifting down a deep river to its destination, could possibly go astray. Does not the current point out the path,--the broad water-way not to be mistaken? So it might appear to one seated in a skiff, and floating down the tranquil Thames, with its well-defined banks. But far different is the aspect of the stupendous Solimoës to the voyager gliding through its _gapo_. I have made use of a word of strange sound, and still stranger signification. Perhaps it is new to your eye, as your ear. You will become better acquainted with it before the end of our voyage; for into the "Gapo" it is my intention to take you, where ill-luck carried the galatea and her crew. On leaving Coary, it was not the design of her owner to attempt taking his craft, so indifferently manned, all the way to Pará. He knew there were several civilized settlements between,--as Barra at the mouth of the Rio Negro, Obidos below it, Santarem, and others. At one or other of these places he expected to obtain a supply of _tapuyos_, to replace the crew who had so provokingly forsaken him. The voyage to the nearest of them, however, would take several days, at the rate of speed the galatea was now making; and the thought of being delayed on their route became each hour more irksome. The ex-miner, who had not seen his beloved brother during half a score of years, was impatient once more to embrace him. He had been, already, several months travelling towards him by land and water; and just as he was beginning to believe that the most difficult half of the journey had been accomplished, he found himself delayed by an obstruction vexatious as unexpected. The first night after his departure from Coary, he consented that the galatea should lie to,--moored to some bushes that grew upon the banks of the river. On the second night, however, he acted with less prudence. His impatience to make way prompted him to the resolution to keep on. The night was clear,--a full moon shining conspicuously above, which is not always the case in the skies of the Solimoës. There was to be no sail set, no use made of the paddles. The crew were fatigued, and wanted rest and repose. The current alone was to favor their progress; and as it appeared to be running nearly two miles an hour, it should advance them between twenty and thirty miles before the morning.
