He knew there would be no fishes close up to the falls, for nothing could swim in such an air-charged mass of water, and nothing would risk itself where it would be beaten down and hurled and whirled against the rocks upon which the waters fell and eddied and played around. Brace knew and felt that so soon as the boat was sucked a little nearer there would be a sudden glide right up to the falling water, and then in an instant they would be beaten down into the darkness right to the bottom, and then go rushing along at a terrible rate, to begin rising a little and a little more till they reached the surface half a mile or more away from where they went down, afterwards to float gently along past where the brig was anchored-- No; he felt that they would never reach the surface again; for, as soon as the rush of the water allowed, the great river would be teeming with shoals of ravenous enemies, and the friends left on board the brig would never learn the cause of the non-return of the boat's crew. All this and more passed through his brain in those frightful minutes as the men tugged hard at the oars, and they kept on parallel with the great descending sheet of water. Now and then, as if divided by a puff of air which did not reach them, the rolling mist opened and displayed piled-up natural piers of rock, towering above their heads and dividing the curtain of gleaming descending waters; but for the most part the falls were hidden from them by an impenetrable veil, and at last they were upon the outskirts of this mist as they rowed on. At first Brace believed that his eyesight was dimming, and he shuddered, for the faces of his fellow-sufferers appeared to him to be strangely distorted and indistinct; but he grasped the reason, and knew now that in a few minutes more they would pass on to their death. But no one else seemed to be affected by the surroundings. To a man, with fixed staring eyes and set teeth, the sailors dragged at their oars, waiting till their officer at the tiller should bid them cease, while his face seemed to have become set to a stony solidity which never changed, for Lynton was ready to meet the worst and, determined to help till the water beat them down, he breathed hard and thrust in the regular seaman's swing. Suddenly Brace felt more than saw that the yard above them swung slightly, and no doubt creaked; but no sound save the deafening roar of the waters could reach to his ear, and he just glanced upward, to feel for the moment that the canvas darkened their position, and it seemed to him that the time had come, for the sail was like one of the wings of death beating over them, and a curious feeling of resignation made him calm.
