"In Louisiana" is a ballad in iambic tetrameter comprised of three quatrains with an abba cddc effe rhyme scheme. Having lived in Louisiana for about half a year in 1995, I can personally attest that the moss and swamps there at that time still met the description given by this poem, which was published almost 100 years earlier.
