The spider, dropping down from twig,

Unfolds a plan of her devising,

A thin premeditated rig

To use in rising.

And all that journey down through space,

In cool descent and loyal hearted,

She spins a ladder to the place

From where she started.

Thus I, gone forth as spiders do

In spider’s web a truth discerning,

Attach one silken thread to you

For my returning.

(E.B. White)
