But the finest music in the room is that which streams out to the ear of the spirit in many an exquisite strain from the hanging shelf of books on the opposite wall. Every volume there is an instrument which some melodist of the mind created and set vibrating with music, as a flower shakes out its perfume or a star shakes out its light. Only listen, and they soothe all care, as though the silken-soft leaves of poppies had been made vocal and poured into the ear.
