"The Tide Rises, the Tide Falls" by Henry Wadsworth Longfellow?

[hottie]

what are the subject matter of stanza one two and three
what does the tide represent
what does the traveler represent
what does the darkness represent
what does the morning represent ....

here is the poem

The tide rises, the tide falls,
The twilight darkens, the curlew calls;
Along the sea-sands damp and brown
The traveler hastens toward the town,
And the tide rises, the tide falls.
Darkness settles on roofs and walls,
But the sea, the sea in darkness calls;
The little waves, with their soft, white hands
Efface the footprints in the sands,
And the tide rises, the tide falls.
The morning breaks; the steeds in their stalls
Stamp and neigh, as the hostler calls;
The day returns, but nevermore
Returns the traveler to the shore.
And the tide rises, the tide falls.
