The Slaves labored in the fields from Sunup to sundown
The poem "Swift Things are Beautiful" by Elizabeth Coatsworth is about how everything around us is fleeting and ephemeral, and quickly goes by while we are not even looking. She wants to say that even though they disappear quickly, these sights are nevertheless beautiful. The point is that we should look around us and admire the view, and enjoy the beauty of it all while it is still there, because it will be gone soon. We should cherish these fleeting moments because we may not get the chance to do that ever again.
