Describe the setting as it is established in the first chapter?

The first chapter is set at the home of Widow Douglas. Huck is describing his adventures with Tom Sawyer, and he is speaking of the life he now leads being raised like the widow's own son. Miss Watson is driving him crazy with her nattering and he goes up to bed. He describes things in this way..........

"The stars were shining, and the leaves rustled in the woods ever so mournful; and I heard an owl, away off, who-whooing about somebody that was dead, and a whippowill and a dog crying about somebody that was going to die; and the wind was trying to whisper something to me, and I couldn't make out what it was, and so it made the cold shivers run over me. Then away out in the woods I heard that kind of a sound that a ghost makes when it wants to tell about something that's on its mind and can't make itself understood, and so can't rest easy in its grave, and has to go about that way every night grieving. I got so down-hearted and scared I did wish I had some company. Pretty soon a spider went crawling up my shoulder, and I flipped it off and it lit in the candle; and before I could budge it was all shriveled up. I didn't need anybody to tell me that that was an awful bad sign and would fetch me some bad luck, so I was scared and most shook the clothes off of me. I got up and turned around in my tracks three times and crossed my breast every time; and then I tied up a little lock of my hair with a thread to keep witches away. But I hadn't no confidence. You do that when you've lost a horseshoe that you've found, instead of nailing it up over the door, but I hadn't ever heard anybody say it was any way to keep off bad luck when you'd killed a spider.

I set down again, a-shaking all over, and got out my pipe for a smoke; for the house was all as still as death now, and so the widow wouldn't know. Well, after a long time I heard the clock away off in the town go boom--boom--boom--twelve licks; and all still again--stiller than ever. Pretty soon I heard a twig snap down in the dark amongst the trees --something was a stirring. I set still and listened. Directly I could just barely hear a "me-yow! me-yow!" down there. That was good! Says I, "me-yow! me-yow!" as soft as I could, and then I put out the light and scrambled out of the window on to the shed. Then I slipped down to the ground and crawled in among the trees, and, sure enough, there was Tom Sawyer waiting for me."
