Read it through once

As the period fixed for our marriage drew nearer, whether from cowardice or a prophetic feeling, I felt my heart sink within me. But I concealed my feelings by an appearance of hilarity that brought smiles and joy to the countenance of my father, but hardly deceived the ever-watchful and nicer eye of Elizabeth. She looked forward to our union with placid contentment, not unmingled with a little fear, which past misfortunes had impressed, that what now appeared certain and tangible happiness might soon dissipate into an airy dream and leave no trace but deep and everlasting regret.
