Determine the rhyme scheme of the following poem. the tides by henry wadsworth longfellow i saw the long line of the vacant shore, the sea-weed and the shells upon the sand, and the brown rocks left bare on every hand, as if the ebbing tide would flow no more. then heard i, more distinctly than before, the ocean breathe and its great breast expand, and hurrying came on the defenceless land the insurgent waters with tumultuous roar. all thought and feeling and desire, i said, love, laughter, and the exultant joy of song have ebbed from me forever! suddenly o'er me they swept again from their deep ocean bed, and in a tumult of delight, and strong as youth, and beautiful as youth, upbore me.
