In chapter 13 of up from slavery why was starting a night school so dear to Washington's heart?

In 'Up From Slavery,' Booker T. Washington developed the idea of night school who didn't have the money to pay for their board. This was important because he no longer had to turn away students who were worthy, but simply did not have the funds to attend. They could take classes at night, that enabled them to still live at home. The requirement was that they work ten hours a day in gainful employment, and that they devote two hours of study each night.
