Read it through once

The old Battery out on the marshes was our place of study, and a broken slate and a short piece of slate-pencil were our educational implements: to which Joe always added a pipe of tobacco. I never knew Joe to remember anything from one Sunday to another, or to acquire, under my tuition, any piece of information whatever. Yet he would smoke his pipe at the Battery with a far more sagacious air than anywhere else,—even with a learned air,—as if he considered himself to be advancing immensely. Dear fellow, I hope he did.
