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.
