   How can we help admiring that open and cheerful brow which, as yet, no care or sin has furrowed; those light and active limbs, full of health and vigour; the eye so quick; the ear so undulled; the memory so ready; the young curiosity so eager to take in new knowledge; the young feelings, not yet spoiled by over-excitement, ready to admire, ready to love?
