Perhaps the librarian will permit you to look over the shelves where the
biographies and works dealing with American history are kept. Don't be
over-awed by the number of volumes, because there are scores and scores
which are of no importance to you. Theodore Parker had a wrong idea
about reading, for once upon a time he undertook to read all the books
in a library, beginning at the first one and proceeding along shelf
after shelf. He never finished the task, of course, because he found
out, after a while, that there are many books which are not worth
reading, and many more which are of value only to specialists in certain
departments of knowledge. No man can "know it all." But every man should
know one thing well, and have a general knowledge of the rest.

For instance, none but an astronomer need know the mathematics of the
science, but all of us should know the principal facts concerning the
universe and the solar system, and it is a pleasure to us to recognize
the different constellations as we gaze up at the heavens on a cloudless
night. None but a lawyer need spend his time reading law-books, but most
of us want to know the broad principles upon which justice is
administered. No one but an economist need bother with the abstract
theories of political economy, but if we are to be good citizens, we
must have a knowledge of its foundations, so that we may weigh
intelligently the solutions of public problems which different parties
offer.

So if you are permitted to look along the shelves of the public library,
you will have no concern with the great majority of the books you see
there; but here and there one will catch your eye which interests you,
and these are the ones for you to read. You have no idea how the habit
of right reading will grow upon you, and what a delightful and valuable
habit it will prove to be. Like any other good habit, it takes pains at
