Apart from that, how did you enjoy the visit?

Sorry, but I keep finding Blackgang Chine out-takes. This one's from The Quiver and a serialised inspirational novel Borne Back, by Emma E Hornibrook, another late-Victorian writer with more credits than you'd think (cue bibliography).

As we once more placed ice upon her head there was another change: she shuddered violently, and raved of a wondrous chasm we had visited in the Island.
      "The Blackgang Chine,'' she murmured, "the Blackgang Chine! Why must I live for ever there! All darkness—all gloom—and that dreadful water ever dashing down. I cannot climb those heights—I cannot escape. Desolate—most desolate! I will not stay. Why force me downward!"
      With a wild motion she sought to fling herself from the bed, but the nurse's strong detaining hand was upon her with a calming touch. She yielded to its influence and lay still.

This is from Borne Back (By the author of "Allie; or, Into the Light,", True to a Trust, etc, etc", [serial in] The Quiver: An Illustrated Magazine for Sunday and General Reading, Cassell, Petter, Galpin & Co., London, Paris & New York, Vol. XVI, 1881).

'See, miss!' he exclaimed, 'there is no danger if they can swim.'

Why all the Blackgang-xiety? Well, Borne Back is broadly a novel about (mild) loss of religious conviction: the narrator goes "frivolous" in some unspecified way, and recovers her faith at the end. It's also a real Mary Sue of a romance. It's not just a poor-but-pious outcome, but she ends up marrying the rich Hugh Capel, who has just inherited estates from his late father, General Capel.
      The problem with the Chine is that the family goes on a pleasant trip to the Isle of Wight (including its "singular chasms") ...

And then we went to Ryde; and in wanderings mid the lovely scenery of the garden isle, in the delightful breezes on the downs, in frequent excursions to its singular chasms, above all, in happy unhindered communion, my mind recovered its calm, and my fears were lulled to rest.

... but it all goes pear-shaped when the narrator’s brother drowns in a yacht race accident (the helmsman has “taken a draught from a secret flask”) and her mother is badly affected. All ends well, however, helped along by that convenient marriage into money.

A Guide to Irish Fiction has this to say about the author:

HORNIBROOK, Mrs Emma E., pseud. 'E.E.H.' ... Children's and religious fiction writer, possibly of Irish origin ... author of 15 works of fiction, at least two of which have clear Irish connections. She also was the author of 'Clouds', and 'Mad Phil', which have not been located.
- A Guide to Irish Fiction, 1650-1900 (Rolf Loeber, Magda Stouthamer-Loeber, Anne Mullin Burnham, Four Courts, 2006).

I think we can beat 15. I haven't got far with biographical details, but credits on many publications put her in America - Worcester, Mass. - in her later career, a supporter of peace and animal causes.

Addendum, 7th June
I have this from the 1915 Who's Who in New England:
HORNIBROOKE, Isabel (Isabel Hornibrook). author; b. in Ireland, of English parents; d. Nicholls Cole-Bowen and Emma Emilia (Bates) Hornibrooke; ed. under pvt. tutors; unmarried. First story accepted for an English magazine at 14; came to America in 1892, and subsequently established home in Worcester, Mass. Address: 23 Hollywood St., Worcester, Mass.

Isabel Hornibrook checks out separately as an author of the early 20th century - more later on that maybe - but this suggests that both mother and daughter were writers. But I don't get the chronology; and in fact I'm wondering if there was some overlap of pseudonyms and writing topics.
