Here is a quote from the booklet 'Roll Back the Carpet' by Hugh Foss.
For example, the figure, half reels of four with corners, was, I
believe, first invented by Elma Taylor for her dance, The White Rose of
Scotland. It has since been included in Ellwyn's Fairy Glen and Mairi's
He adds as a footnote: The White Rose of Scotland was given in The Reel
No. 19 of June 1954, but the figure had, with Miss Taylor's permission,
been described in 'We Agree to Differ' in The Reel No. 7 of June 1952.
'Roll Back the Carpet' and 'We Agree to Differ' are collections of
articles written by Hugh Foss and published in The Reel (London Branch
of the RSCDS). A single booklet containing these articles is still
available. These are unbeatable (IMHO) for scholarly, yet entertaining
and enlightened, observations on the evolution of Scottish Country
Dancing in the modern era.
