Natural History

E.B. White

The spider, dropping down from twig,
Unwinds a thread of her devising:
A thin, premeditated rig
To use in rising.

And all the journey down through space,
In cool descent, and loyal-hearted,
She builds a ladder to the place
From which she started.

Thus I, gone forth, as spiders do,
In spider's web a truth discerning,
Attach one silken strand to you
For my returning.
