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.

"No sooner had we fairly entered it than I became aware it was much
narrower than I had supposed. To the left of us there was the long
uninterrupted shoal, and to the right a high, steep bank heavily
overgrown with bushes. Above the bush the trees stood in serried ranks.
The twigs overhung the current thickly, and from distance to distance a
large limb of some tree projected rigidly over the stream. It was then
well on in the afternoon, the face of the forest was gloomy, and a
broad strip of shadow had already fallen on the water. In this shadow
