Read these first three stanzas from Mariana, and then answer the question that follows it: With blackest moss the flower-plots Were thickly crusted, one and all: The rusted nails fell from the knots That held the pear to the gable-wall. The broken sheds look'd sad and strange: Unlifted was the clinking latch; Weeded and worn the ancient thatch Upon the lonely moated grange. She only said, 'My life is dreary, He cometh not,' she said; She said, 'I am aweary, aweary, I would that I were dead!' Her tears fell with the dews at even; Her tears fell ere the dews were dried; She could not look on the sweet heaven, Either at morn or eventide. After the flitting of the bats, When thickest dark did trance the sky, She drew her casement-curtain by, And glanced athwart the glooming flats. She only said, 'The night is dreary, He cometh not,' she said; She said, 'I am aweary, aweary, I would that I were dead!' Upon the middle of the night, Waking she heard the night-fowl crow; The cock sung out an hour ere light: From the dark fen the oxen's low Came to her: without hope of change, In sleep she seem'd to walk forlorn, Till cold winds woke the gray-eyed morn About the lonely moated grange. She only said, 'The day is dreary, He cometh not,' she said; She said, 'I am aweary, aweary, I would that I were dead!'
