There are not many persons who know what wonders are opened to them in the

stories and visions of their youth; for when as children we listen and dream,

we think but half-formed thoughts, and when as men we try to remember, we are

dulled and prosaic with the poison of life. But some of us awake in the night

with strange phantasms of enchanted hills and gardens, of fountains that sing

in the sun, of golden cliffs overhanging murmuring seas, of plains that stretch

down to sleeping cities of bronze and stone, and of shadowy companies of heroes

that ride caparisoned white horses along the edges of thick forests; and then

we know that we have looked back through the ivory gates into that world of

wonder which was ours before we were wise and unhappy.
