Read the excerpt from “ Crossing Brooklyn Ferry.”

Just as you feel when you look on the river and sky, so I felt,
Just as any of you is one of a living crowd, I was one of a crowd,
Just as you are refresh'd by the gladness of the river and the
bright flow, I was refresh'd,
Just as you stand and lean on the rail, yet hurry with the swift
current, I stood yet was hurried,
Just as you look on the numberless masts of ships and the
thick-stemm'd pipes of steamboats, I look'd.
