On page 115 of Lyddie by Katherine Paterson, what payment does Lyddie receive?

Lyddie receives fifty dollars from Ezekial on page 115 of Lyddie by Katherine Paterson.

Earlier in the book, Lyddie met the runaway slave Ezekial.  Moments before parting, Lyddie decided to give Ezekial the money that she got from selling the calf in chapter two.  The calf sold for twenty-five dollars.  Ezekial refuses to take the money as a gift.  He is only willing to accept the money as a loan, and he promises to pay it back with interest, after he reaches the safety of Canada.  

The money that Lyddie receives on page 115 is Ezekial's repayment of Lyddie's loan, plus interest.  Lyddie can hardly believe it.  Fifty dollars is a lot of money, and the repayment of the loan allows Lyddie to begin thinking that she just might indeed be able to pay off the rest of the family debt.  

With one piece of paper her account had bulged like a cow about to freshen. She must find out at once what the debt was.  She might already have enough to cover it.
