In fact, Miss Margaret was the WILL of the body corporate.
Miss Sibyl was of milder nature and more melancholy temperament; she had a poetic turn of mind, and occasionally wrote verses.

Some of these had been printed on satin paper, and sold for objects of beneficence at charity bazaars.

The county newspapers said that the verses "were characterized by all the elegance of a cultured and feminine mind." The other two sisters agreed that Sibyl was the genius of the household, but, like all geniuses, not sufficiently practical for the world.
Miss Sarah Chillingly, the youngest of the three, and now just in her forty-fourth year, was looked upon by the others as "a dear thing, inclined to be naughty, but such a darling that nobody could have the heart to scold her." Miss Margaret said "she was a giddy creature." Miss Sibyl wrote a poem on her, entitled, "Warning to a young Lady against the Pleasures of the World." They all called her Sally; the other two sisters had no diminutive synonyms.

Sally is a name indicative of fastness.

But this Sally would not have been thought fast in another household, and she was now little likely to sally out of the one she belonged to.
