So far, nothing had been seen of the rajah's prahus. When questioned on the subject, he replied that they were all down on the coast, trading with the natives; but it was so improbable that they should have been sent away while the rajah was in fear of an attack by his neighbors that no credence was given to the assertion. The ship's boats often went out for long rows on the river, ostensibly--as the captain told the rajah, who inquired suspiciously as to the meaning of these excursions--for the sake of giving the crews active exercise, but principally in order to take soundings of the river, and to investigate the size and positions of the creeks running into it. One day the gig and cutter had proceeded farther than usual; they had started at daybreak, and had turned off into what seemed a very small creek, that had hitherto been unexplored, as from the width of its mouth it was supposed to extend but a short distance into the forest. The master's mate was in command of one boat, the second lieutenant of the other; Harry Parkhurst accompanied the latter. After pushing through the screen of foliage that almost closed the entrance to the creek, the boats rowed on for some distance. For half a mile the width was but some fifteen yards, and the trees met in an arch overhead, then it widened considerably. “This is just the sort of place,” the lieutenant said to Harry, “where the rajah's prahus may be hidden away. We had best go along as noiselessly as possible. If we were to come upon them suddenly they might fire upon us, and that would bring on a general row. If we should catch sight of them, it would be best to take the news to the captain, and let him act as he thinks fit.” He ordered the men to cease rowing until the gig came alongside. “Mr. Morrison,” he said, “it seems to me that this is a likely place for the prahus to be hidden. We had better try and discover if this is the case, without being ourselves seen; therefore have all the oars, except four, laid in, and let the men muffle those with their stockings, and be most careful to dip them into the water without making a splash. Let absolute silence be preserved in the boat. I will lead the way as before, and if I hold up my hand stop rowing instantly.” “Aye, aye, sir!” the mate replied. The same precautions were taken by the cutter, and the boats proceeded noiselessly. Presently the stream narrowed again, until it seemed that they were approaching its termination, and the boat stopped rowing. “I fancy we have come to the end of it, Mr. Morrison,” the lieutenant said in a low voice. “I am afraid so too, sir; there is no room for the oars, and we shall either have to punt the boats, or to drag them by the bushes.” The lieutenant was about to give the order to turn when Harry said, suddenly, “There is a current, sir. I have had my eye upon that root, and we have drifted backwards a couple of feet since we lost way, so there must be a stretch of water above us.”
