as huck thinks about the letter and the lobg raft trip down the river, what does he remember most?

He remembers Jim's friendship and goodness.

"I'd see him standing my watch on top of his'n, stead of calling me, so I could go on sleeping; and see him how glad he was when I come back out of the fog; and when I come to him agin in the swamp, up there where the feud was; and such-like times; and would always call me honey, and pet me, and do everything he could think of for me, and how good he always was; and at last I struck the time I saved him by telling the men we had smallpox aboard, and he was so grateful, and said I was the best friend old Jim ever had in the world, and the only one he's got now; and then I happened to look around, and see that paper."

hello Jill...
