satisfied myself that there was only a narrow channel on each side of
it, even at high tide, and not, as on our side, a broad expanse of
water. Indeed, this knowledge alone was worth all the trouble I had
taken, and to attempt much more than this, in the face of a curiosity
already roused, would have been a waste of future opportunities. I could
try again, with the benefit of this new knowledge, on a point where the
statements of the negroes had always been contradictory.

Resolving, however, to continue the observation a very little longer,
since the water felt much warmer than I had expected, and there was no
sense of chill or fatigue, I grasped at some wisps of straw or rushes
that floated near, gathering them round my face a little, and then,
drifting nearer the wharf in what seemed a sort of eddy, was able,
without creating further alarm, to make some additional observations on
points which it is not best now to particularize. Then, turning my back
upon the mysterious shore which had thus far lured me, I sank softly
below the surface and swam as far as I could under water.

During this unseen retreat, I heard, of course, all manner of gurglings
and hollow reverberations, and could fancy as many rifle-shots as I
pleased. But on rising to the surface all seemed quiet, and even I did
not create as much noise as I should have expected. I was now at a safe
distance, since they were always chary of showing their boats, and they
would hardly take personally to the water. What with absorbed attention
first, and this submersion afterwards, I had lost all my bearings but
the stars, having been long out of sight of my original point of
departure. However, the difficulties of the return were nothing; making
a slight allowance for the flood-tide, which could not yet have turned,
I should soon regain the place I had left. So I struck out freshly
against the smooth water, feeling just a little stiffened by the
