I can only think that the book is read because it deals with the difficulties of schooling, which do not change. Please note: the difficulties, not the problems. Problems are solved or disappear with the revolving times. Difficulities remain. It will always be difficult to teach well, to learn accurately; to read, write, and count readily and competently; to acquire a sense of history and start one's education or anothers.
