When speaking about other students at hampton, what does Booker note?

The students at Hampton ranged in age, but all were extremely earnest in studying and working. Many were just as poor as Washington. Washington was impressed that all seemed to desire to prepare themselves to lift up their people back home, rather than thinking of themselves. He also expressed his admiration and gratitude for the Yankee teachers who devoted themselves to helping the Negroes of the South.
