The bank
helps in other ways. Do you see that stump on the false point?'
'Ay, ay, sir.'
'Well, the water is just up to the roots of it. You must make a note of
that.'
'Why?'
'Because that means that there's seven feet in the chute of 103.'
'But 103 is a long way up the river yet.'
'That's where the benefit of the bank comes in. There is water enough
in 103 NOW, yet there may not be by the time we get there; but the bank
will keep us posted all along. You don't run close chutes on a falling
river, up-stream, and there are precious few of them that you are
allowed to run at all down-stream. There's a law of the United States
against it. The river may be rising by the time we get to 103, and in
that case we'll run it. We are drawing - how much?'
'Six feet aft, - six and a half forward.'
'Well, you do seem to know something.'
'But what I particularly want to know is, if I have got to keep up an
everlasting measuring of the banks of this river, twelve hundred miles,
month in and month out?'
'Of course!'
My emotions were too deep for words for a while. Presently I said - '
And how about these chutes. Are there many of them?'
'I should say so. I fancy we shan't run any of the river this trip as
you've ever seen it run before - so to speak. If the river begins to
rise again, we'll go up behind bars that you've always seen standing out
of the river, high and dry like the roof of a house; we'll cut across
low places that you've never noticed at all, right through the middle of
bars that cover three hundred acres of river; we'll creep through cracks
where you've always thought was solid land; we'll dart through the woods
and leave twenty-five miles of river off to one side; we'll see the
hind-side of every island between New Orleans and Cairo.'
'Then I've got to go to work and learn just as much more river as I
already know.'
'Just about twice as much more, as near as you can come at it.'
'Well, one lives to find out. I think I was a fool when I went into
this business.'
'Yes, that is true. And you are yet. But you'll not be when you've
learned it.'
'Ah, I never can learn it.'
'I will see that you DO.'
By and by I ventured again -
'Have I got to learn all this thing just as I know the rest of the
river - shapes and all - and so I can run it at night?'
'Yes. And you've got to have good fair marks from one end of the river
to the other, that will help the bank tell you when there is water
enough in each of these countless places - like that stump, you know.
When the river first begins to rise, you can run half a dozen of the
deepest of them; when it rises a foot more you can run another dozen;
the next foot will add a couple of dozen, and so on: so you see you have
to know your banks and marks to a dead moral certainty, and never get
them mixed; for when you start through one of those cracks, there's no
backing out again, as there is in the big river; you've got to go
through, or stay there six months if you get caught on a falling river.
There are about fifty of these cracks which you can't run at all except
when the river is brim full and over the banks.'
'This new lesson is a cheerful prospect.'
'Cheerful enough. And mind what I've just told you; when you start into
one of those places you've got to go through. They are too narrow to
turn around in, too crooked to back out of, and the shoal water is
always up at the head; never elsewhere. And the head of them is always
likely to be filling up, little by little, so that the marks you reckon
their depth by, this season, may not answer for next.'
'Learn a new set, then, every year?'
'Exactly. Cramp her up to the bar! What are you standing up through
the middle of the river for?'
The next few months showed me strange things. On the same day that we
held the conversation above narrated, we met a great rise coming down
the river. The whole vast face of the stream was black with drifting
dead logs, broken boughs, and great trees that had caved in and been
washed away. It required the nicest steering to pick one's way through
this rushing raft, even in the day-time, when crossing from point to
point; and at night the difficulty was mightily increased; every now and
then a huge log, lying deep in the water, would suddenly appear right
under our bows, coming head-on; no use to try to avoid it then; we could
only stop the engines, and one wheel would walk over that log from one
end to the other, keeping up a thundering racket and careening the boat
in a way that was very uncomfortable to passengers. Now and then we
would hit one of these sunken logs a rattling bang, dead in the center,
with a full head of steam, and it would stun the boat as if she had hit
a continent. Sometimes this log would lodge, and stay right across our
nose, and back the Mississippi up before it; we would have to do a
little craw-fishing, then, to get away from the obstruction.
