Amid the various subjects which present themselves to the attention of the philosophic inquirer, we know not of anyone more national in its interests, or worthy of minute attention, than that which investigates the theory and practice of public instruction. The assertion that ‘knowledge is power,’ is verified on every page of history, present or past.
