What does Katie overhear regarding Matt during a conversation between Aunt Annie and Miss Carrington?

Miss Carrington, the teacher at the local school, comes by to speak to Aunt Annie. Katie is dispatched into the house to get tea for the guest. As Katie is returning, she overhears Matt's name. Katie is then sent down to the lake to finish trimming beans for supper. Katie drops a knife, and while she is looking for it, she overhears Miss Carrington ask her aunt to allow Matt to remain in school. Matt is extremely intelligent and should be able to get scholarships for the university. However, Aunt Annie refuses because of the lack of money.
