No. 1.
ENIGMA.
In bugle, not in horn.
In aurora, not in morn.
In railroad, not in sleeper.
In woodbine, not in creeper.
In apples, not in cherries.
In plums, but not in berries.
In equator, not in pole.
In mouse, but not in mole.
In mingle, not in blend.
In favorite, not in friend.
In girdle, not in belt.
In Norman, not in Celt.
A river I, upon whose banks of old
Lived many a warrior chivalrous and bold;
And massive ancient towers still frown on me
As I rush onward to the restless sea.
Owlet.
