-A Jelly-Fish by Marianne Moore
-
-Visible, invisible,
-A fluctuating charm,
-An amber-colored amethyst
-Inhabits it; your arm
-Approaches, and
-It opens and
-It closes;
-You have meant
-To catch it,
-And it shrivels;
-You abandon
-Your intent—
-It opens, and it
-Closes and you
-Reach for it—
-The blue
-Surrounding it
-Grows cloudy, and
-It floats away
-From you.

-My Shadow by Robert Louis Stevenson
-
-I have a little shadow that goes in and out with me,
-And what can be the use of him is more than I can see.
-He is very, very like me from the heels up to the head;
-And I see him jump before me, when I jump into my bed.
-
-The funniest thing about him is the way he likes to grow—
-Not at all like proper children, which is always very slow;
-For he sometimes shoots up taller like an India-rubber ball,
-And he sometimes gets so little that there’s none of him at all.
-
-He hasn’t got a notion of how children ought to play,
-And can only make a fool of me in every sort of way.
-He stays so close beside me, he’s a coward you can see;
-I’d think shame to stick to nursie as that shadow sticks to me!
-
-One morning, very early, before the sun was up,
-I rose and found the shining dew on every buttercup;
-But my lazy little shadow, like an arrant sleepy-head,
-Had stayed at home behind me and was fast asleep in bed.

-Theme in Yellow by Carl Sandburg
-
-I spot the hills 
-With yellow balls in autumn. 
-I light the prairie cornfields 
-Orange and tawny gold clusters 
-And I am called pumpkins. 
-On the last of October 
-When dusk is fallen 
-Children join hands 
-And circle round me 
-Singing ghost songs 
-And love to the harvest moon; 
-I am a jack-o'-lantern 
-With terrible teeth 
-And the children know 
-I am fooling.
