Marshal wants to read aloud this stanza from “The Sandpiper” by Celia Thaxter:

Across the lonely beach we flit,
One little sandpiper and I,
And fast I gather, bit by bit,
The scattered driftwood, bleached and dry.
The wild waves reach their hands for it,
The wild wind raves, the tide runs high,
As up and down the beach we flit,
One little sandpiper and I.

What could Marshal do as he reads to help listeners visualize the action in the poem?
