So we went over to where the canoe was, and while he
built a fire in a grassy open place amongst the trees, I
fetched meal and bacon and coffee, and coffee-pot and
frying-pan, and sugar and tin cups, and the nigger was set
back considerable, because he re

Well, I blieve you, Huck. I I RUN OFF.
But mind, you said you wouldn tell you know you
said you wouldn tell, Huck.
Well, I did. I said I wouldnt, and Ill stick to it.
Honest INJUN, I will. People would call me a low- down
where I was. I talked along, but he only set there and
looked at me; never said nothing. Then I says:
Its good daylight. Les get breakfast. Make up your
camp fire good.
Whats de use er makin up de camp fire to cook

across that camp fire, stopping every minute or two to
listen. But I hadnt no luck somehow; I couldnt seem to
find the place. But by and by, sure enough, I catched a
glimpse of fire away through the trees. I went for it,
cautious and slow. By and by I was
I didnt wait, but shoved out and paddled away easy. I
tied up in the old place, and reckoned I would sleep in the

And every time I waked up I thought somebody had me

quit shooting and dropped over to the Missouri shore and
went home to the town.
I knowed I was all right now. Nobody else would
come a-hunting after me. I got my traps out of the canoe
and made me a nice camp in the thick woods. I made a
kind of a tent ou
again so as to have them out of sight, and I put out the fire
and scattered the ashes around to look like an old last
years camp, and then clumb a tree.
I reckon I was up in the tree two hours; but I didnt see
nothing, I didnt hear nothing I only THOUGHT
beginning to show. They would all come handy by and
by, I judged.
Well, I went fooling along in the deep woods till I
judged I warnt far from the foot of the island. I had my
gun along, but I hadnt shot nothing; it was for protection;
thought I would kill
Everybody was talking about the murder, but the captain
broke in and says:
Look sharp, now; the current sets in the closest here,
and maybe hes washed ashore and got tangled amongst
the brush at the waters edge. I hope so, anyway.
I didnt hope so. They al
I tuck out en shin down de hill, en spec to steal a skift

I WANTED to go and look at a place right about the
middle of the island that Id found when I was exploring;
so we started and soon got to it, because the island was
only three miles long and a quarter of a mile wide.
This place was a tolerable
So we went back and got the canoe, and paddled up
abreast the cavern, and lugged all the traps up there. Then
we hunted up a place close by to hide the canoe in,
amongst the thick willows. We took some fish off of the
lines and set them again, and begun t

And Jim said you mustnt count the things you are
going to cook for dinner, because that would bring bad
luck. The same if you shook the table-cloth after
sundown. And he said if a man owned a beehive and that
man died, the bees must be told about it befor
I got a good place amongst the leaves, and set there on
a log, munching the bread and watching the ferry- boat,
and very well satisfied. And then something struck me. I

the ferryboats side. You see, they was firing cannon over
the water, trying to make my carcass come to the top.
I was pretty hungry, but it warnt going to do for me to
start a fire, because they might see the smoke. So I set
there and watched the cannon-s
I went up and set down on a log at the head of the
island, and looked out on the big river and the black
driftwood and away over to the town, three mile away,
where there was three or four lights twinkling. A
monstrous big lumber-raft was about a mile up
mostly hove at the nigger and the gov- ment, though he
give the tub some, too, all along, here and there. He
hopped around the cabin con- siderable, first on one leg
and then on the other, hold- ing first one shin and then
the other one, and at last he le
make any noise, and got down the gun. I slipped the
ramrod down it to make sure it was loaded, then I laid it
across the turnip barrel, pointing towards pap, and set
down behind it to wait for him to stir. And how slow and
still the time did drag along.
RGIT up! What you bout?
I opened my eyes and looked around, trying to make
out where I was. It was after sun-up, and I had been
sound asleep. Pap was standing over me looking sourQand
sick, too. He says:
What you doin with this gun?
Oh, theyre here! dont touch me dont! hands off
theyre cold; let go. Oh, let a poor devil alone!
Then he went down on all fours and crawled off,
begging them to let him alone, and he rolled himself up in
his blanket and wallowed in under the old pine tabl
