I fidgeted up and down the raft, abusing myself to myself, and Jim was fidgeting up and down past me.

We neither of us could keep still.

Every time he danced around and says, "Dah's Cairo!" it went through me like a shot, and I thought if it WAS Cairo I reckoned I would die of miserableness.
Jim talked out loud all the time while I was talking to myself.

He was saying how the first thing he would do when he got to a free State he would go to saving up money and never spend a single cent, and when he got enough he would buy his wife, which was owned on a farm close to where Miss Watson lived; and then they would both work to buy the two children, and if their master wouldn't sell them, they'd get an Ab'litionist to go and steal them.
It most froze me to hear such talk.

He wouldn't ever dared to talk such talk in his life before.
