"Two pilgrims were quarrelling in hurried whispers as to which bank. 'Left.' 'no, no; how can you? Right, right, of course.' 'It is very serious,' said the manager's voice behind me; 'I would be desolated if anything should happen to Mr. Kurtz before we came up.' I looked at him, and had not the slightest doubt he was sincere. He was just the kind of man who would wish to preserve appearances. That was his restraint. But when he muttered something about going on at once, I did not even take the trouble to answer him. I knew, and he knew, that it was impossible. Were we to let go our hold of the bottom, we would be absolutely in the air—in space. We wouldn't be able to tell where we were going to—whether up or down stream, or across—till we fetched against one bank or the other—and then we wouldn't know at first which it was. Of course I made no move. I had no mind for a smash-up. You couldn't imagine a more deadly place for a shipwreck. Whether we drowned at once or not, we were sure to perish speedily in one way or another. 'I authorize you to take all the risks,' he said, after a short silence. 'I refuse to take any,' I said shortly; which was just the answer he expected, though its tone might have surprised him. 'Well, I must defer to your judgment. You are captain,' he said with marked civility. I turned my shoulder to him in sign of my appreciation, and looked into the fog. How long would it last? It was the most hopeless lookout. The approach to this Kurtz grubbing for ivory in the wretched bush was beset by as many dangers as though he had been an enchanted princess sleeping in a fabulous castle. 'Will they attack, do you think?' asked the manager, in a confidential tone.
"I did not think they would attack, for several obvious reasons. The thick fog was one. If they left the bank in their canoes they would get lost in it, as we would be if we attempted to move. Still, I had also judged the jungle of both banks quite impenetrable—and yet eyes were in it, eyes that had seen us. The riverside bushes were certainly very thick; but the undergrowth behind was evidently penetrable. However, during the short lift I had seen no canoes anywhere in the reach—certainly not abreast of the steamer. But what made the idea of attack inconceivable to me was the nature of the noise—of the cries we had heard. They had not the fierce character boding immediate hostile intention. Unexpected, wild, and violent as they had been, they had given me an irresistible impression of sorrow. The glimpse of the steamboat had for some reason filled those savages with unrestrained grief. The danger, if any, I expounded, was from our proximity to a great human passion let loose. Even extreme grief may ultimately vent itself in violence—but more generally takes the form of apathy....
"You should have seen the pilgrims stare! They had no heart to grin, or even to revile me: but I believe they thought me gone mad—with fright, maybe. I delivered a regular lecture. My dear boys, it was no good bothering. Keep a lookout? Well, you may guess I watched the fog for the signs of lifting as a cat watches a mouse; but for anything else our eyes were of no more use to us than if we had been buried miles deep in a heap of cotton-wool. It felt like it, too—choking, warm, stifling. Besides, all I said, though it sounded extravagant, was absolutely true to fact. What we afterwards alluded to as an attack was really an attempt at repulse. The action was very far from being aggressive—it was not even defensive, in the usual sense: it was undertaken under the stress of desperation, and in its essence was purely protective.
"It developed itself, I should say, two hours after the fog lifted, and its commencement was at a spot, roughly speaking, about a mile and a half below Kurtz's station. We had just floundered and flopped round a bend, when I saw an islet, a mere grassy hummock of bright green, in the middle of the stream. It was the only thing of the kind; but as we opened the reach more, I perceived it was the head of a long sand-bank, or rather of a chain of shallow patches stretching down the middle of the river. They were discoloured, just awash, and the whole lot was seen just under the water, exactly as a man's backbone is seen running down the middle of his back under the skin. Now, as far as I did see, I could go to the right or to the left of this. I didn't know either channel, of course. The banks looked pretty well alike, the depth appeared the same; but as I had been informed the station was on the west side, I naturally headed for the western passage.
