We went up to the lake. We sit down to view the beauty of the scene around. All was still save the gentle breeze that curled the lake. Not a bird was heard through all that wood. We were the only ones that intruded on Nature's dead repose. --How fast fly the hours when in the society of those we esteem. The sun had sunk behind the hill ere we thought of home.
Compare the following passage (once again involving Clara--see under O13n5 ) from The Romance of the Forest:
She adhered to her resolution, and towards the close of day went into the garden to amuse herself. The evening was still and uncommonly beautiful. Nothing was heard but the faint shivering of the leaves, which returned but at intervals, making silence more solemn, and the distant murmurs of the torrents that rolled among the cliffs. As she stood by the lake, and watched the sun slowly sinking below the alps, whose summnits were tinged with gold and purple; as she saw the last rays of light gleam upon the waters whose surface was not curled by the lightest air, she sighed, "Oh! how enchanting would be the sound of my lute at this moment, on this spot, and when every thing is so still around me! --pp. 251-52.
Did Louisa read The Romance of the Forest? According to Thackery, writing around 1860, Ann Radcliffe's The Mysteries of Udolpho was
"one of the most famous romances--which ever was published in this country [England]. The beauty and elegance of Valancourt made your young grandmammas' gentle hearts to beat with respectful sympathy."
Quoted in The Mysteries of Udolpho (The World's Classics, Oxford University Press, 1980), p. xiii. (The novel was first published in 1794.) One wonders whether The Romance of the Forest wasn't just about as popular.
