Read this stanza from “The Song of Wandering Aengus” by William Butler Yeats.
 I went out to the hazel wood,
 Because a fire was in my head,
 And cut and peeled a hazel wand,
 And hooked a berry to a thread;
 And when white moths were on the wing,
 And moth-like stars were flickering out,
 I dropped the berry in a stream
 And caught a little silver trout.
