How much money did Ona make a day?

Ona made eight to ten dollars a week.

"Ona came home and reported that the forelady seemed to like her, and had said that, while she was not sure, she thought she might be able to put her at work sewing covers on hams, a job at which she would earn as much as eight or

ten dollars a week."

This is the only quote I have found that deals with the wages paid for child labor. Do you have a specific chapter for this question?

"There are little children here, scarce in their teens, who can hardly see the top of the work benches—whose parents have lied to get them their places—and who do not make the half of three hundred dollars a year, and perhaps not even the third of it."
