Other atmospheric effects, which occasionally occur in this District, have been alluded to elsewhere in these notes; as the aerial armies seen on Souter Fell, and the Helm Cloud and Bar, with their accompanying wind, generated upon Cross Fell. Phenomena of a singular character, which may be ascribed to reflections from pure and still water in the lakes, have also attracted observation. Mr. Wordsworth has described two of which he was an eye-witness. "Walking by the side of Ulswater," says he, "upon a calm September morning, I saw deep within the bosom of the lake, a magnificent Castle, with towers and battlements; nothing could be more distinct than the whole edifice;--after gazing with delight upon it for some time, as upon a work of enchantment, I could not but regret that my previous knowledge of the place enabled me to account for the appearance. It was in fact the reflection of a pleasure house called Lyulph's Tower--the towers and battlements magnified and so much changed in shape as not to be immediately recognised. In the meanwhile, the pleasure house itself was altogether hidden from my view by a body of vapour stretching over it and along the hill-side on which it extends, but not so as to have intercepted its communication with the lake; and hence this novel and most impressive object, which, if I had been a stranger to the spot, would, from its being inexplicable, have long detained the mind in a state of pleasing astonishment. Appearances of this kind, acting upon the credulity of early ages, may have given birth to, and favoured the belief in, stories of sub-aqueous palaces, gardens, and pleasure-grounds--the brilliant ornaments of Romance. "With this inverted scene," he continues, "I will couple a much more extraordinary phenomenon, which will shew how other elegant fancies may have had their origin, less in invention than in the actual process of nature.
