There's a listing about her on the Online Books Page listing her works available online, including a very cursory Wikipedia article, but neither show her and maybe there's a reason for that.
She looks like somebody we might rule out as too old-fashioned to be relevant.
Don't be fooled.
I'm going to give a story that meets a difficult topic sometimes wanted by teachers and parents: cleanliness, neatness, or tidiness -- call it what you will, it's a subject needed for preschool and primary grades. Bryant had a timeless understanding of what my Australian storytelling friends so aptly call "The Littlies." In How to Tell Stories to Children and Some Stories to Tell she has three age groups of "Stories Selected and Adapted for Telling." This is in the Kindergarten and Grade 1 section, but most preschool classes could handle it, too.
(Looking at later in life, just the other day at rehearsal, cast members were comparing notes on "personal hygiene" and mentioned a talented actor or two who could have used this story, a shower, and some deodorant. We might have wished this story had been one of those stories told back when those fellows were "Littlies" in case it made a difference! Stories do have a way of staying in our minds and that is why they can be a gentle but powerful way to teach.)
Because Bryant is quick to point out that stories need adaptation, don't feel a change or two is out of line. Boys no longer wear pinafores, so just change it to clothes. If you want this to be a fairy tale, there's no problem with the boy meeting a "Tidy Angel", but it could just as easily be the "Tidy Fairy" or . . . By all means, however, keep this light.
Yet another personal side note here, I remember being shocked to hear my mother reading Cat in the Hat to my two daughters like it was a Greek Tragedy! Not only that, she wasn't fooling when she saw the mess Thing 1 and Thing 2 made! This story from Laura E. Richards' classic 1903 book, The Golden Windows, should be done with a sense of fun and even sly cheek-in-your-tongue.
I hope you let the parting grumble by the pig be at least somewhat exaggerated.
Having talked so much about Sara Cone Bryant and the book where she explains storytelling, here's a bonus, her Table of Contents to show you why you might want to download your own copy. If you look on the list of stories at Grades 2 and 3 you will see "The Burning of the Rice Fields." The 2004 Indian Ocean tsunami shows that not all stories are fairy tales and they do indeed have a value 100 years later.
******************This is part of a series of postings of stories under the category, "Keeping the Public in Public Domain." The idea behind Public Domain was to preserve our cultural heritage after the authors and their immediate heirs were compensated. I feel strongly current copyright law delays this intent on works of the 20th century. My own library of folklore includes so many books within the Public Domain I decided to share stories from them. I hope you enjoy discovering new stories.
At the same time, my own involvement in storytelling regularly creates projects requiring research as part of my sharing stories with an audience. Whenever that research needs to be shown here, the publishing of Public Domain stories will not occur that week. This is a return to my normal monthly posting of a research project here. Response has convinced me that "Keeping the Public in Public Domain" should continue along with my monthly postings as often as I can manage it.
