We were very tired, we were very merry—

We had gone back and forth all night on the ferry.
It was bare and bright, and smelled like a stable—
But we looked into a fire, we leaned across a table,
We lay on a hill-top underneath the moon;
And the whistles kept blowing, and the dawn came soon.

We were very tired, we were very merry—
We had gone back and forth all night on the ferry;
And you ate an apple, and I ate a pear,
From a dozen of each we had bought somewhere;
And the sky went wan, and the wind came cold,
And the sun rose dripping, a bucketful of gold.

We were very tired, we were very merry,
We had gone back and forth all night on the ferry.
We hailed, “Good morrow, mother!” to a shawl-covered head,
And bought a morning paper, which neither of us read;
And she wept, “God bless you!” for the apples and pears,
And we gave her all our money but our subway fares.

How do the first two lines of each stanza support the "back and forth" movement of the ferry?

The repetition of "We were very tired, we were very merry" in the first two lines of each stanza reflects the back and forth movement of the ferry. This repetition emphasizes the weariness and excitement of the journey, mirroring the rhythm of the ferry as it moves back and forth across the water.
