What main events happen in Chapters 34-36 in The Adventures of Tom Sawyer by Mark Twain?

These are the final short chapters of the Twain classic.
After Tom and Huck return from finding the treasure, they also find that the Widow
Douglas has a house full of people and some news of her own: She is going to adopt Huck.
But before she can get Huck's response, Tom blurts out that they are rich. Tom brings in
the sacks of gold and when they count the money, they find that it totals $12,000. Tom
and Huck became the biggest celebrities in the town. The Widow Douglas and Aunt Polly
put their boys' money in the bank "at six per cent," and even gave them a gigantic
allowance (for the time!) of $1 per day. But such life was not for Huck, and the two
decided to get their gang back together--with an initiation at
midnight.
