What is the significance of the title of this chapter?

Washington's plan at Tuskegee was to have students do not only the agricultural and domestic work, but also to construct their own buildings. The most trying experience in those days was attempting to make bricks. The bricks were needed to construct Tuskegee buildings, but also there was a demand in the general market. However, the work was hard and dirty, and it was difficult to persuade students to help. The process required special skills and knowledge that nobody initially had. The first three kilns failed, and there were no funds to try again.
