The Lurline Cave is justly regarded as one of the most charming chambers in the group. The _coup d'oeil_ is magnificent. It does not need any close examination to find that it has some distinctive features which show that, although there is no aqueous accommodation for the queen of the water nymphs, whose name it bears, the appellation of this portion of the Lucas Cave cannot, etymologically at least, be considered as a _lucus a non lucendo_. There are the "coral bowers" and cells to which Rudolph was transported; the "halls of liquid crystal, where the water lilies bloom;" there is the cool grot in which the Water Queen dwelt; there is the rock on which she sat "when all was silent save the murmur of the lone wave, and the nightingale that in sadness to the moon telleth her lovelorn tale;" there is Rhineberg's magic cave, with its "wedges of gold from the upper air;" there are the distant recesses to which Lurline sent the gnome while she restored to life her mortal affinity. With such surroundings it is easy to reproduce, link by link, the rosy chain which enthralled the German Count and "The Daughter of the Wave and Air." Or, to take the more rollicking version by "Thomas Ingoldsby, Esq." Here is "a grand stalactite hall," like that which rose above and about the impecunious "Sir Rupert the Fearless," when he followed to the bottom of the Rhine the dame whose-- "Pretty pink silken hose cover'd ankles and toes; In other respects she was scanty of clothes; For so says tradition, both written and oral, Her _one_ garment was loop'd up with bunches of coral." Where-- "Scores of young women diving and swimming, * * * * All slightly accoutred in gauzes and lawns, Came floating about him like so many prawns," and where their queen, Lurline, lost her heart and her plate, and, according to the same reverend author, her cajoler, whose disastrous fate inspired the moral-- "Don't fancy odd fishes! Don't prig silver dishes! And to sum up the whole in the shortest phrase I know, Beware of the Rhine, and take care of the Rhino!"
