This is the land-the Sunset washes — China

This-is the land-the Sunset washes-1
These-are the Banks of the Yellow Sea-
Where it rose-or whither it rushes-
These-are the Western Mystery!

Night after Night 5
Her purple traffic
Strews the landing with Opal Bales-
Merchantmen-poise upon Horizons-
Dip-and vanish like Orioles!
