How would Miss Blanche deal with Adele?

From the text, we can infer that Blanche would send Adele to boarding school.

"Mr. Rochester, I thought you were not fond of children?"
"Nor am I."
"Then, what induced you to take charge of such a little doll as that?" (pointing to Adele). "Where did you pick her up?"
"I did not pick her up; she was left on my hands."
"You should have sent her to school."
"I could not afford it: schools are so dear."
