What does Simon Legree do with Tom's clothes and personal belongings?

Legree sells Tom's belongings at auction. 

"... the articles very readily were sold to one or another, and the empty trunk finally put up at auction. It was a good joke, they all thought, especially to see how Tom looked after his things, as they were going this way and that; and then the auction of the trunk, that was funnier than all, and occasioned abundant witticisms.”
