A narrow fellow in the grass

A narrow Fellow in the Grass
Occasionally rides -
You may have met Him - did you not
His notice sudden is -

The Grass divides as with a Comb -
A spotted shaft is seen -
And then it closes at your feet
And opens further on -

He likes a Boggy Acre
A Floor too cool for Corn
Yet when a Boy, and Barefoot -
I more than once at Noon
Have passed, I thought, a Whip lash
Unbraiding in the Sun
When stooping to secure it
It wrinkled, and was gone -

Several of Nature's People
I know, and they know me -
I feel for them a transport
Of cordiality -

But never met this Fellow
Attended, or alone
Without a tighter breathing
And Zero at the Bone -
