he was hard at work, a thrall to
strange witchcraft, full of improving knowledge. He was useful because
he had been instructed; and what he knew was this--that should the water
in that transparent thing disappear, the evil spirit inside the boiler
would get angry through the greatness of his thirst, and take a terrible
vengeance. So he sweated and fired up and watched the glass fearfully
(with an impromptu charm, made of rags, tied to his arm, and a piece of
polished bone, as big as a watch, stuck flatways through his lower lip),
while the wooded banks slipped past us slowly, the short noise was left
behind, the interminable miles of silence--and we crept on, towards
Kurtz. But the snags were thick, the water was treacherous and shallow,
the boiler seemed indeed to have a sulky devil in it, and thus neither
that fireman nor I had any time to peer into our creepy thoughts.

"Some fifty miles below the Inner Station we came upon a hut of reeds,
an inclined and melancholy pole, with the unrecognizable tatters of
what had been a flag of some sort flying from it, and a neatly stacked
woodpile. This was unexpected. We came to the bank, and on the stack of

meant for the place where it could be only found after approach.
Something was wrong above. But what--and how much? That was the
question. We commented adversely upon the imbecility of that telegraphic
style. The bush around said nothing, and would not let us look very far,
either. A torn curtain of red twill hung in the doorway of the hut, and
flapped sadly in our faces. The dwelling was dismantled; but we could
see a white man had lived there not very long ago. There remained a rude
table--a plank on two posts; a heap of rubbish reposed in a dark corner,
and by the door I picked up a book. It had lost its covers, and the
pages had been thumbed into a state of extremely dirty softness; but the
back had been lovingly stitched afresh with white cotton thread, which
looked clean yet. It was an extraordinary find. Its title was, 'An
Inquiry into some Points of Seamanship,' by a man Tower, Towson--some
